Product Overview
Anping Xinye Metal Wire Mesh Products Co., Ltd is a professional manufacturer located in Hengshui, Hebei, China. Our factory has developed steadily since 2020 and now operates a 5,000-10,000 square meter plant with 51-100 experienced employees. We produce this heavy duty expanded metal sheet from high quality carbon steel coil, supplied in a standard 4 feet by 8 feet panel with 3mm strand width. It is a strong and versatile mesh panel for industrial, construction, security and architectural applications. Every panel can be delivered with a mill test report for material traceability and inspection confidence.
Key Features and Benefits
- One-piece structure: The sheet is expanded from a single steel plate, not welded or woven, so it will not loosen or unravel under repeated loading.
- High strength-to-weight ratio: Carbon steel provides strong support while keeping the panel light enough for easy handling and installation.
- Non-slip surface: The raised diamond strands create safe walking surfaces for platforms, walkways, stair treads and floor gratings.
- Open area for ventilation: The diamond mesh lets air, heat and light pass through, helping to avoid dust collection and improving visibility in safety screens.
- Versatile fabrication: Panels can be cut, sheared, flattened, bent, welded or bolted using standard metalworking tools.
- Low maintenance: With an optional paint, galvanized or powder-coated finish, the sheet can resist corrosion and serve for many years.
- Material documentation: A mill test report is provided to confirm the carbon steel grade and mechanical properties.

Material, Construction and Performance
Expanded metal is produced by slitting a metal sheet and stretching it into a network of diamond-shaped openings. This cold-working process increases the strength and rigidity of the panel while minimizing waste. The carbon steel substrate used in this product is selected for its predictable mechanical behavior and easy weldability. The result is a heavy duty expanded metal sheet that performs well under foot traffic, machine loads, security barriers and outdoor installations. The 4x8 foot panel dimensions reduce the number of seams required in large projects, while the 3mm strand width gives a strong mesh line that withstands impact and deformation.
Compared with solid metal plate, expanded metal sheet offers a practical balance of strength, open area and material efficiency. It is often used where both protection and visibility are required, such as machine guards, security windows, partitions, fencing and ventilation panels. The raised strand edges also contribute to skid resistance, making this sheet suitable for wet or oily environments in factories and construction sites.
Common Applications
- Walkways, platforms, catwalks and mezzanine flooring
- Machine guards, safety screens and enclosure panels
- Security fencing, window guards and door infill panels
- Ventilation grilles, air inlet screens and filter supports
- Industrial storage racks, pallet fences and shelf backing
- Architectural cladding, sunshades and decorative screens
- Truck and trailer flooring, step treads and ramps

Frequently Asked Questions
Q1: What does 4' x 8' mean in this product?
It means the expanded metal panel is four feet wide and eight feet long, approximately 1220 mm x 2440 mm. This is a common standard size for building and industrial projects.
Q2: What is a 3mm strand width?
The strand is the solid metal band around each opening in the expanded sheet. The 3mm strand width indicates the thickness of that band, giving the mesh strong and stable bars.
Q3: Is the sheet galvanized?
This product is carbon steel and can be supplied as black or with a galvanized, painted or powder-coated finish. Please tell us the surface treatment required for your application.
Q4: Can you cut the sheet to custom sizes?
Yes, we can shear or cut the expanded metal sheet to custom dimensions, and we can also flatten, bend or further fabricate it as needed. Custom sizes are available upon request.
Q5: What is a mill test report?
A mill test report is a material quality certificate issued by the steel mill. It lists chemical composition, mechanical properties and heat number, and it confirms the material specification for traceability.
Q6: Can I use this sheet outdoors?
Yes, but if the sheet will be exposed to rain or humidity, we recommend a galvanized or painted finish to improve corrosion resistance. Bare carbon steel should be protected with paint or oil for long-term outdoor use.
Q7: What are typical uses for heavy duty expanded metal?
It is commonly used for walkways, platforms, machine guards, security screens, fencing, ventilation grilles, storage racks and architectural infill panels.
Q8: Do you provide samples or trial orders?
Samples and small trial orders are available. As a factory, we can also provide production support, packing advice and export documentation for larger quantities.
