Common Technical Analysis
Q1 What are the main anti-slip methods and materials currently available on the market?
• Material Classification： Generally, anti-slip effectiveness is ranked by coefficient of friction as follows： Silicon Carbide (Carborundum) > Rubber/PVC > Aluminum. • Installation Methods： o Installing stair nosing： Offers optimal effectiveness, is easy to install and suitable for DIY, with low maintenance costs. o Chemical etching： Utilizes chemical reactions to create pores. Frequent cleaning is required to prevent pores from filling up, which would cause loss of anti-slip function. o Sandblasting service： Requires a high level of professional construction. The quality of the work directly affects the lifespan, and future maintenance is more difficult.
Q2 Are stair nosing suitable for all stair materials?
• Evaluation Focus： The primary consideration is the usage environment (indoor or outdoor) and the anti-slip requirement, rather than the surface material. • Material Recommendations： o Silicon Carbide stair tread： Features a high friction coefficient (ASTM D1894 up to 1.1), offers a stylish and design-forward appearance, and maintains excellent slip resistance even when exposed to water or oil, making it suitable for both indoor and outdoor applications. o Rubber stair tread： Available in vibrant colors, offers strong decorative appeal, and is easy to replace, suitable for indoor environments that are dry and free from oil or water.
Q3 Why do stair nosings need to be clearly distinguished between indoor and outdoor models?
• Environmental Stress： Indoor environments are stable, with designs focusing on aesthetics and tactile feel; outdoor areas must withstand year-round rain, strong UV radiation, and temperature fluctuations. • Weather Resistance Requirements： Outdoor anti-slip stair nosing must possess stronger waterproofing, wear resistance, and weather resistance capabilities to maintain stable anti-slip performance under extreme weather conditions, preventing loss of anti-slip function due to environmental degradation.
Q4 What are the main differences between commercially available products and "Wenly anti-slip stair nosing"?
• Design Risks： Many commercially available stair nosing products do not consider long-term safety or use less rigorous material selection, leading to a short service life and a lack of dedicated after-sales maintenance. • Brand Endorsement： Wenly boasts a 50-year reputation guarantee. We design products from a safety perspective, meticulously select weather-resistant materials, and implement stringent quality control. The product/installation warranties offered by our company are superior to the warranty conditions of similar products in the Taiwan market. The actual warranty period is subject to product model, installation method, and project specifications, ensuring that our products offer exceptional value.
Q5 Have Wenly stair nosing products passed professional inspection?
• Authoritative Reports： Yes, Wenly can provide various specification inspection reports according to customer requirements. • Testing Institutions： We have long-term partnerships with authoritative institutions for testing, including： o Plastic Industry Development Center. o Intertek. o SGS Taiwan. • Standards： The scope of testing covers internationally recognized standards such as CNS and ASTM.
Q6 Is the Silicon Carbide (Carborundum) adhesive stair nosing prone to detachment?
• Brand Recognition： Please recognize 【Wenly】. Products on the market vary in quality. Non-professional manufacturers often encounter issues such as sand surface peeling or inadequate adhesive on the base material. • Product Tiers： o Economy Type (PVC Base)： When installed according to our DIY recommendations, it offers excellent resistance to detachment and saves labor costs. o Advanced Type (Aluminum Base)： Provides robust support, is wear-resistant, durable, and not easily damaged. We also offer professional installation and warranty services.
Q7 Does adding a "metal reinforcement plate" to the rubber anti-slip strip effectively prevent shrinkage?
Technical Truth： The anti-shrinkage property of rubber strips should be determined by the material properties of the raw material. Due to the significant difference in thermal expansion coefficients between plastics and metals, forced bonding can instead cause stress failure. Safety Hazard： For example, after prolonged outdoor exposure to sunlight, the separation of dissimilar materials can lead to cracking of the rubber strip or protrusion of metal edges. This not only fails to achieve the anti-shrinkage purpose but may also cause injury to users through contact with exposed metal pieces. Wenly insists on returning to scientific formulations and pure materials, eliminating such products that prioritize packaging over substance. Brand Commitment： "We prioritize safety above all else, preferring not to sell rather than compromise the potential safety of our users." This commitment to product safety is the highest principle of the Wenly brand spirit.
Q8 What are the advantages and disadvantages of wrap-around corner stair nosing (corner design)?
• Structural Risk： While the wraparound design can enhance edge slip resistance, the connection between the rubber strip and aluminum strip relies solely on adhesion. Prolonged use under foot pressure can easily cause the rubber strip to detach, leading to accidents. • Wenly Solution： Our products consistently utilize aluminum alloy edges with anti-slip patterns. This mechanical structure increases the anti-slip coefficient and extends the service life, completely eliminating the risk of rubber strip dislodgement.
Q9 When selecting stair nosing, which is more important： "stair tread material" or "base structure"?
Professional Insight： Each component serves its purpose. The "stair tread" ensures immediate safety, while the "base" guarantees long-term stability. The Stair Tread： Guardian of Safety： The stair tread (e.g., silicon carbide or rubber) directly provides friction, crucial for immediate safety while walking. As stair treads are consumables, good design allows for localized replacement when the tread wears out or you wish to change the color scheme, without dismantling the entire structure. This is both economical and environmentally friendly. The Base： The Unchanging Foundation： The base (aluminum alloy base) is the supporting frame for the entire system. It is typically embedded or securely fastened to the stairs and is not recommended for frequent replacement. Therefore, we strongly advise selecting high-strength, corrosion-resistant, premium metal materials for the base. Concluding Recommendation： "A one-time installation of the base, paired with flexible tread replacement." Wenly's rigorously selected aluminum base material offers far superior strength and enhanced corrosion resistance compared to other brands, providing the industry's most durable base design. This saves you the cost of base replacement when the stair tread wears out and offers the convenience of updating slip resistance performance at any time.
Q10 When conducting "barrier-free facility inspections" for buildings, what are the regulatory requirements for the color and design of stair nosing on stairs?
Amended according to the Ministry of the Interior's Order No. 1070820550 dated January 4, 2019, effective July 1, 2019 "Accessibility Design Standards for Buildings." The three critical areas most frequently leading to rejection during project acceptance are： 1. Stair Tread Slip Resistance and "Flushness" Requirement (Standard 304.3)： Regulations stipulate that the edges of stair treads must be treated for slip resistance and be flush with the tread. For new constructions, we strongly recommend implementing the "pre-embedded stair nosing" installation method during the construction phase to fundamentally resolve flushness and durability issues. 2. Tactile Warning Zones at Stair Starts and Ends (Standard 306.1)： Within 30 cm of the start and end of a flight of stairs, warning facilities with a depth of 30-60 cm and a "different color and texture" must be clearly installed to provide clear boundary guidance for the elderly or visually impaired. 3. Elevator (Lift) Guidance Material (Standard 403.2)： The floor 30 cm in front of the Braille call button should have a "**60 cm in length and 30 cm in width**" treatment of different material, and it is explicitly stipulated that it "shall not obstruct wheelchair users' movement." ⚠️ 【Wenly Exclusive Solution： Responding to the Trend of Increasingly Strict Inspection Based on Real Case Feedback Since 2025】 In the past, the construction industry often used "self-adhesive stair nosing" for simple installation to pass inspections. However, starting from 2025, based on actual cases in public works and accessibility engineering in recent years, it has been observed that inspection requirements for installation stability, flushness, and slip resistance are receiving greater attention. The accessibility inspection standards for new constructions are becoming universally stricter. Inspectors strongly require the use of installation methods that are "stable and have long-lasting fixation." Traditional, simple adhesive methods are highly likely to lead to rejection during acceptance. Therefore, Wenly offers "reinforced anti-slip plates" specifically for high-standard building projects. This solution offers the following three irreplaceable advantages： Can be pre-embedded and secured： Completely eliminates the risk of adhesive failure, meeting the latest stringent inspection standards. Extremely thin and flush： Ensures smooth passage for wheelchairs, perfectly complying with flushness regulations for elevator lobbies and stairs. High color contrast and rough texture： Combined with high-grade Silicon Carbide design, ensuring clear boundary perception for visually impaired individuals. Corresponding slip resistance and fixation solutions can be provided based on engineering design and accessibility standard requirements, assisting architectural and construction units in reducing acceptance risks.
Q11 For anti-slip engineering on basement driveway ramps or slopes, is it necessary to completely close the driveway for several days during construction?
No. We understand that the "traffic dark period" is the biggest pain point for most community management committees and commercial office buildings. Compared to traditional anti-slip engineering which requires complete resurfacing, re-tiling, and a long curing period (usually closed for 3 to 7 days), Wenly's "high-rigidity metal base combined with non-directional Silicon Carbide (Carborundum)" anti-slip plate, specifically designed for high-intensity driveways, supports "no complete closure and rapid phased construction." Traffic can be reopened quickly after installation and fixing, completely resolving the critical danger of driveway slippage with maximum efficiency, without affecting residents' daily routines and vehicle access.
Q12 Does Wenly provide on-site installation services including labor and materials, or do you only offer wholesale building materials?
Both are available. We offer a comprehensive, one-stop professional service from raw material manufacturing to final installation. As a local factory with 50 years of experience, we not only provide high-quality anti-slip building materials for bulk purchasing and wholesale to builders, construction companies, and industry peers across Taiwan; for large-scale construction projects, public works (such as MRT systems and hospitals), or driveway improvement projects, we also have an experienced dedicated team to provide on-site anti-slip installation services with both materials and labor. From site survey and assessment, specification recommendations, to precise construction, we offer clients the most reassuring complete protection solutions.
Q13 If we have special specifications or drawings, can Wenly assist with "custom development" of anti-slip building materials?
Absolutely, this is precisely the core advantage of Wenly as a "manufacturer." Architectural drawings and site conditions vary immensely. If standard specifications cannot meet your needs, we possess robust capabilities for customized mass production. Please contact us for inquiries with sufficient order volume. Whether it's custom cutting to special dimensions, exclusive aluminum alloy mold development, or high-end anti-slip materials for specific demanding environments (such as food factories resistant to oil stains or outdoor extreme climates), we can collaborate with designers or engineering units based on their drawings for sample customization and R&D, precisely crafting building materials that meet exclusive specifications.
Q14 How should stair nosing be cleaned and maintained after installation to ensure the longest possible service life?
Wenly's high-end anti-slip products possess excellent weather resistance and anti-shrinkage/anti-aging properties, making daily maintenance very simple. It is recommended to use clean water with a neutral detergent and a soft brush or sponge mop for surface cleaning. Please note two major taboos during daily maintenance： Strictly avoid using strong acidic or alkaline detergents： These types of chemicals will damage the reinforced anodized layer on the surface of the aluminum alloy base, leading to premature metal oxidation and loss of luster. They will also significantly reduce the lifespan of the surface material. Avoid using steel brushes or overly rough abrasive tools： This is to prevent scratching the anti-slip tread under excessive scrubbing, which would affect the original high anti-slip coefficient. By maintaining a gentle and correct cleaning method, our anti-slip systems can maintain excellent grip and aesthetics for a long time.
Q15 How long does stair nosing installation take? Will normal operations be affected during installation?
Wenly has 50 years of professional installation experience. Standard anti-slip stair nosing installation for small to medium-sized stairs can be completed within 1-2 business days. We utilize a standardized, factory-direct installation process： on-site measurement → precise cutting → surface cleaning → professional adhesion and fixing → completion inspection. For locations such as hospitals, shopping malls, and office buildings that require continuous operation, we can also arrange for night-time or holiday installations to minimize operational impact. All installations are performed by the Wenly team to ensure consistent quality.
Q16 How long can driveway anti-slip treatments last after installation? Is regular maintenance required?
Wenly's driveway anti-slip solutions utilize durable steel plates with professional anchoring methods, offering a lifespan of over 5 years under normal use. Compared to general anti-slip stickers or coatings, reinforced anti-slip stair nosings offer overwhelming advantages in wear resistance and corrosion resistance, making them particularly suitable for high-load, high-friction environments such as driveways. We recommend performing routine inspections every six months to ensure fixing screws are secure. Wenly provides comprehensive after-sales warranty, and our engineering team is always available to provide technical support for any issues after installation.
Where can I buy silicon carbide stair nosing? Can I install it myself?
Silicon Carbide stair nosing can be ordered directly through the official Wenly website or by phone (02-2331-0649). Factory-direct sales eliminate intermediary markups. We offer two solutions： (1) Material purchase and self-installation – suitable for construction teams with installation experience, providing comprehensive technical consultation; (2) Material and labor package – a team of Wenly professional technicians will perform on-site installation to ensure anti-slip effectiveness and durability.

Q18 What regulatory standards must be met for anti-slip engineering on accessible ramps?
Accessible ramp anti-slip engineering must comply with the Ministry of the Interior's "Code of Practice for Barrier-Free Facilities Design," which specifies ramp slope, handrail height, platform dimensions, and ground anti-slip standards. Wenly's Silicon Carbide (Carborundum) friction coefficient, tested by SGS to ASTM D1894, is over 1.1, far exceeding the legal minimum requirement (0.5). We collaborate closely with architects and construction companies from the design phase to ensure all anti-slip engineering, from material selection to construction details, meets barrier-free regulations. We have assisted hundreds of public construction projects in improving barrier-free anti-slip facilities and passing inspections.
Q19 What is the difference between Wenly anti-slip stair nosing and the anti-slip stair nosing purchased at general hardware stores?
Stair nosing available at general hardware stores are often resold products from distributors, lacking original manufacturer technical support and quality assurance. Wenly Anti-slip is a Taiwan-based professional stair nosing manufacturer with 50 years of experience, offering three key differences： (1) Quality Control — We maintain full in-house control from raw material selection to finished product shipment, ensuring strict quality management for every batch. (2) Professional Consultation — Our technical team, with 50 years of experience, provides selection advice and installation guidance to prevent product misuse and failures.

Actual warranty periods are determined by product model, installation method, and project specifications, ensuring our products offer exceptional value. Any product issues are directly handled by the factory, avoiding the situation where "distributors pass the buck to importers." For public works and corporate procurement, choosing direct sales from the original manufacturer is the safest and most economical long-term solution.
Q20 I want to buy stair nosing from a hardware store to install myself. What is the fundamental difference compared to professional installation by your company?
Common issues with DIY stair nosing installation： insufficient surface cleaning, incorrect adhesive selection, or improper bonding. Based on our past maintenance cases, this can lead to edge lifting, mold growth, or detachment within six months. Wenly's professional installation service first assesses the floor material (tiles, stone, cement, wood) and selects the most suitable industrial-grade adhesive and corresponding product. After professional installation, the stair nosing will achieve its maximum lifespan. Furthermore, we offer an installation warranty, providing peace of mind that DIY cannot match.
Q21 Just applying something, why does the anti-slip project require professional assessment? Will it be expensive?
The value of professional anti-slip assessment lies in： (1) Material judgment： Different floor materials require different anti-slip products. (2) Environmental assessment： Damp bathrooms, greasy kitchens, and outdoor areas exposed to sun and rain all require completely different product choices. (3) Long-term cost： Professional installation once can ensure many years of use, avoiding the hidden costs of repeated DIY failures. Regarding costs, Wenly offers free online or on-site assessments and quotes. We provide multiple solution options based on site conditions. Installation begins only after your confirmation, ensuring complete transparency.
Q22 Do stair nosings or anti-slip products accumulate soap scum or mold? How often do they need maintenance?
Wenly selected materials possess excellent anti-fouling and anti-mold properties, making them resistant to dirt accumulation and mold growth under normal use. Daily maintenance only requires a neutral detergent and a soft brush to lightly scrub the surface. We also offer regular "Anti-Slip Health Check Services," where you can book professional personnel to conduct on-site anti-slip coefficient testing, ensuring safety effectiveness is always maintained in optimal condition.
Q23 For a home with elderly and children, what is the safest anti-slip planning?
Home safety planning should consider "high-risk areas throughout the house"： the bathroom is the primary focus, followed by stairs, kitchens, balconies, and entrances. We offer tailored solutions based on user behavior in different areas (elderly gripping, toddlers crawling, walking paths). For example, for barefoot use, skin-friendly patches can be used without causing injury, and stairs are recommended to be equipped with edging and anti-slip stair nosing to enhance visual cues and prevent slips.
Q24 I heard some anti-slip stair nosings are toxic. Are your products safe?
All Wenly products come with relevant testing data from SGS, Plastics Industry Research and Development Center, or Intertek, which can be provided based on project requirements. Our products comply with CNS national standards, are free from heavy metals and toxic substances, making them safe building materials. Inexpensive anti-slip stair nosings of unknown origin on the market may use inferior materials containing heavy metals or volatile organic compounds, posing health concerns with prolonged exposure. When purchasing, be sure to identify the "Wenly" brand and its related certifications to protect your family's health.
Q25 Why do the stair nosings in outdoor restaurants or public spaces look different from those at home?
This is due to the significant difference between "residential grade" and "commercial/industrial grade" products. Public spaces have extremely high requirements for wear resistance, fire resistance, load-bearing capacity, and weather resistance, necessitating the use of heavy-duty stair nosing with a metal structure (aluminum base) that complies with CNS and Building Technical Regulations. Wenly, with 50 years of deep cultivation, is the leading brand for this type of professional heavy-duty stair nosing, with a project portfolio covering major public works such as high-speed rail, metro systems, and hospitals.

(2) A professional consultant will visit your site to take measurements and assess the floor conditions. (3) Based on the site conditions and your requirements, we will provide solutions with different specifications and transparent quotations. (4) After confirming the solution, a construction date will be arranged. (5) Inspection upon completion and warranty provided. The entire process is pressure-free with no forced sales.
Q27 What materials are available for stair nosing? How should I choose?
Wenly offers three main material series： (1) Silicon Carbide (Carborundum) tread： Highest friction (up to 1.1), provides anti-slip performance in both wet and oily conditions, suitable for indoor and outdoor use, and is the most versatile. (2) Rubber tread： Available in a wide range of colors with a comfortable feel, suitable for dry indoor stairs, and enhances aesthetic appeal. (3) Aluminum alloy： Durable and robust, ideal for outdoor or high-traffic areas. If unsure, you are welcome to schedule a free on-site assessment with our professional technicians to recommend the most suitable material.
Q28 How long does it take to install stair nosing? Can the area be used normally during installation?
For residential stair anti-slip installations, completion typically takes about half a day, depending on the area and installation method. Normal foot traffic is permitted immediately after the anti-slip stair nosing is adhered. If there is a need to wait for the adhesive to fully cure, a professional technician will explain the recommended waiting time for each installation method.
Q29 My old stair nosing is lifting, can I just replace one piece, or do I need to redo the entire installation?
This depends on the situation! If it's an early Wenly-installed replaceable stair nosing, you only need to replace the surface material while retaining the base to avoid damaging the floor. For other brands or older adhesive types, it may be necessary to remove the old adhesive and re-prepare the floor before installing a new product. We recommend taking photos or scheduling a free on-site assessment, and we will provide you with the most cost-effective repair solution.
Q30 Do anti-slip engineering projects have a warranty? How long is the warranty period?
Wenly's product/installation warranties exceed those of similar products in the Taiwanese market. The actual warranty period is subject to the product model, installation method, and project conditions, ensuring excellent value for your investment. During the warranty period, non-human-induced damages will be repaired or replaced free of charge at your location. This demonstrates our confidence in our products and installation quality, and is your greatest assurance when choosing a professional manufacturer.
