Anping Xinye Metal Wire Mesh Products Co., Ltd is a professional manufacturer based in Hengshui, Hebei, China, focusing on metal wire mesh and expanded metal products. This 4mm thick expanded metal grating with serrated anti-slip surface is engineered specifically for stair treads and walkways where maximum safety is required. It offers excellent traction, high strength-to-weight ratio, and long service life even under continuous foot traffic and heavy industrial use.
Our expanded metal grating is made from a single sheet of metal that is simultaneously slit and stretched, creating a diamond-shaped mesh without any welding or joints. The serrated surface is formed by an additional process that raises each strand edge into a sharp, rough profile, effectively preventing slipping in wet, oily, or dusty environments. This makes it an reliable choice for factories, warehouses, power plants, refineries, and public infrastructure projects.
Key Features:
- Anti-Slip Serrated Surface: Every mesh strand features raised serrations that increase friction and reduce the risk of slips, even with steel-toe boots or wet footwear.
- 4mm Thick Construction: Provides a robust load-bearing capacity while remaining lighter than solid checker plate or welded bar grating.
- One-Piece Expanded Design: No weak welded joints — the continuous metal structure delivers uniform strength across the entire panel.
- Ventilation and Drainage: Open diamond mesh allows water, snow, mud, and debris to fall through, keeping the walking surface cleaner and safer.
- Easy to Cut and Install: Can be cut, shaped, and fixed with standard tools; suitable for both new construction and retrofits.
- Maintenance-Free: With proper surface treatment, it requires minimal upkeep and offers a long service life.

Why Choose This Expanded Metal Grating?
Compared to ordinary flattened expanded metal or welded bar grating, the serrated surface of this product provides noticeably better slip resistance. The 4mm base thickness gives it a solid feel underfoot without excessive weight, which means easier handling during installation and lower shipping costs. The diamond pattern also offers natural flexibility — the panel can conform to slightly curved surfaces, making it adaptable for curved staircases or transition areas where flat steel plate would be unsuitable.
For safety-conscious project managers, our grating helps meet workplace safety requirements for anti-slip flooring. The open mesh design reduces the accumulation of dust and liquids, which is a key advantage in food processing facilities, offshore platforms, and chemical plants where hygiene and slip prevention are critical. Additionally, the expanded metal structure uses less material than solid plate, providing a cost-effective solution without compromising strength.
Customization Options:
- Panel width and length can be customized to match your exact stair tread or walkway dimensions.
- Carbon steel, stainless steel, or aluminum materials are available — stainless steel is recommended for marine or highly corrosive environments.
- Hot-dip galvanizing provides long-term corrosion protection for outdoor use; powder coating is available if you require specific safety colors.
- Grating can be supplied with flat bars welded along the edges for reinforced stair nosings or framed walkway panels.
- Custom serration patterns and mesh geometries are possible for special traction requirements — contact our engineering team for assistance.

Frequently Asked Questions
Q1: Can this expanded metal grating be used for both stair treads and flat walkways?
Yes. The 4mm serrated expanded metal grating is well suited for both stair treads and walkway platforms. For stair nosing applications, we can supply flat bar edge reinforcement or bent profiles so the grating fits securely over the step nose. For flat walkways, it can be laid directly on support beams or subframes.
Q2: How does the serrated surface perform in wet or oily conditions?
The serrated edges create a series of raised sharp ridges that bite into shoe soles, providing slip resistance significantly higher than plain expanded metal or smooth steel plate. The open mesh pattern also allows water, oil, and debris to fall through instead of pooling on the surface. However, extremely unusual industrial spills should still be addressed with additional absorbents or hose-down maintenance.
Q3: Can the panel be cut to custom sizes for my project?
Absolutely. Our factory can cut panels to your exact width and length before shipment. We can also fabricate stair treads with welded end plates, bend them to form a nosing lip, or supply plain panels that you can cut and install on site using a standard angle grinder or metal cutting saw.
Q4: What material options are available for this 4mm expanded metal grating?
We offer carbon steel (Q235, Q355), stainless steel (304, 316), and aluminum alloy. Carbon steel is the most economical and is usually specified with hot-dip galvanizing for outdoor use. Stainless steel 316 is recommended for coastal environments or chemical processing areas where corrosion resistance is critical. Aluminum provides a lightweight option for platforms where weight reduction matters.
Q5: Which surface treatment should I choose for exterior stair treads?
For exterior installations, hot-dip galvanizing is a solid choice because it creates a thick zinc coating that protects the base metal against rust for many years. Powder coating in safety yellow or black can also be applied over galvanized surfaces for added color visibility. If you need a specific finish, let us know the environment and expected lifespan, and we can offer recommendations.
Q6: What is the typical lead time for bulk stair tread orders?
Lead time depends on order quantity and surface treatment. For standard carbon steel panels with hot-dip galvanizing, production usually takes 15 to 25 days to complete. Custom stainless steel orders may require 20 to 30 days. We recommend sharing your required quantities and delivery date so we can plan accordingly and provide a confirmed schedule.
Q7: How does expanded metal compare to welded grating for walkway safety?
Expanded metal is made from a single sheet without welding, which removes the risk of weld failure on individual joints. It also naturally has a rough, textured surface and does not require separate anti-slip bars. Welded bar grating with serrated cross bars is another common option, but expanded metal generally offers better open-area ratio, lighter weight, and easier fabrication for certain applications.
Q8: What is the minimum order quantity?
Our standard minimum order quantity for stock sizes is 50 square meters. For custom sizes, special materials, or fabricated stair treads with welded end plates, the MOQ may be lower depending on the specification. We encourage customers to contact us with their project details — we are flexible with trial orders so you can evaluate the product quality first.
