Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer of welded bar grating with an annual export value of US$5-10 million. Our S355 Carbon Steel Welded Bar Grating with 100x100mm mesh and 6mm thickness offers superior strength and durability for heavy-duty industrial applications. Each panel comes with a Mill Test Report to ensure material traceability and quality assurance.
This welded bar grating is designed to provide maximum load-bearing capacity while maintaining an open area for drainage, ventilation, and light transmission. The S355 carbon steel grade delivers excellent weldability and structural performance, making it ideal for platforms, walkways, trench covers, and mezzanine floors. With our advanced manufacturing techniques, we ensure consistent panel dimensions and precise welding for long-lasting service.
Key Features & Technical Specifications
- Material: S355 carbon steel (yield strength ≥355 MPa) – higher strength than standard mild steel, reducing weight while maintaining load capacity.
- Mesh Size: 100mm x 100mm (center-to-center) – balanced open area for safety and functionality.
- Bearing Bar Thickness: 6mm – robust enough for heavy traffic and static loads.
- Surface Finish: Mill finish (black) as standard; hot-dip galvanized, painted, or epoxy coating available upon request.
- Manufacturing Process: Electric resistance welding (ERW) – strong, uniform joints without filler metal.
- Panel Sizes: Customizable lengths and widths up to 6m x 2m, or as per customer requirements.
- Mill Test Report: Included with each shipment to verify chemical composition and mechanical properties.
- Applications: Industrial platforms, catwalks, stair treads, drainage covers, security grilles, and marine environments.

Advantages & Benefits
- High Load Capacity: S355 steel provides 30% higher yield strength than S235, allowing for longer spans and reduced material usage.
- Excellent Drainage & Ventilation: The 100x100mm open area prevents water accumulation and allows air circulation, reducing corrosion risk.
- Easy Installation: Lightweight yet strong panels can be cut, welded, or clamped on-site with standard tools.
- Customizable Options: Choose from various bearing bar heights, surface coatings, and panel dimensions to meet specific project requirements.
- Mill Test Report Included: Full material traceability ensures compliance with engineering specifications and quality control standards.
- Anti-Slip Surface: Optional serrated bearing bars or raised patterns enhance safety for pedestrian use.
Our welded bar grating is manufactured using precision automated welding equipment, ensuring consistent quality and tight tolerances. Each panel undergoes visual inspection and dimensional checking before packing. With over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory has supplied grating to diverse markets including North America, Europe, Southeast Asia, and Africa. Our annual export value of US$5-10 million reflects our commitment to reliable delivery and customer satisfaction.
We can produce panels in various sizes: standard widths from 1m to 2m, lengths up to 6m, and custom dimensions upon request. For projects requiring enhanced corrosion resistance, hot-dip galvanized finish is available with a uniform zinc coating following ASTM A123 or equivalent standards. Our factory also offers serrated bearing bars for improved slip resistance in wet or oily conditions.
Typical Applications
- Industrial Platforms & Walkways: Heavy-duty flooring for factories, warehouses, and power plants.
- Drainage Covers: Trench grates for municipal, commercial, and residential drainage systems.
- Stair Treads: Safe, durable steps for ladders and staircases.
- Mezzanine Floors: Lightweight yet strong panels for additional storage space.
- Security Grilles: Fencing, gates, and barriers for safety and security.
FAQ
1. What is the difference between S355 and standard mild steel grating?
S355 has a higher yield strength (355 MPa) compared to standard mild steel (e.g., S235 at 235 MPa). This allows S355 grating to carry heavier loads with thinner bars, reducing weight and cost while maintaining performance.
2. Do you provide the Mill Test Report for each shipment?
Yes, a Mill Test Report (MTR) is included with every order to certify the chemical composition and mechanical properties of the S355 carbon steel used.
3. Can I get customized panel sizes?
Absolutely. We can cut panels to your specified length and width. Maximum dimensions are typically 6m x 2m, but we can discuss larger requirements.
4. What surface finishes are available?
Standard finish is mill (black). Hot-dip galvanized, painted, and epoxy coatings are available upon request. Galvanizing provides excellent corrosion resistance for outdoor or harsh environments.
5. How is the grating packaged for export?
Panels are bundled with steel strapping, protected with edge protectors, and wrapped in waterproof material or placed in wooden crates for sea freight. We ensure safe handling during transit.
6. What is the typical lead time?
For standard sizes and mill finish, lead time is 10-15 working days. Custom sizes and galvanized finishes may require 20-25 working days depending on order quantity.
7. Can you supply serrated or anti-slip grating?
Yes, we offer serrated bearing bars (with teeth) that provide excellent slip resistance. Please specify when ordering.
8. Do you ship to international destinations?
Yes, we export worldwide from ports including Tianjin, Qingdao, Shanghai, and Foshan. Our main markets cover North America, Europe, Asia, Africa, and Oceania.
