As a leading manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in heavy-duty steel perforated sheets designed for demanding industrial applications. Our 4x8 Feet Mild Steel Perforated Sheet Heavy Duty 3mm Thick 12mm Round Hole ASTM A36 combines structural integrity with precise perforation, offering a reliable solution for construction, filtration, and architectural projects. With annual export value exceeding US$5 million and a global footprint spanning across North America, South America, Europe, and Asia, we deliver consistent quality that meets international standards.
This perforated sheet is manufactured from high-quality ASTM A36 mild steel, ensuring excellent weldability, machinability, and strength. The 3mm thickness provides robust load-bearing capacity, while the 12mm round holes in a staggered pattern optimize airflow, drainage, and visibility. Ideal for heavy-duty applications such as machine guards, security screens, shelving, and acoustic panels, this product offers a balance of durability and functionality.
Key Features & Benefits
- Heavy-Duty Construction: 3mm thick mild steel plate withstands high impact, pressure, and wear, suitable for industrial environments.
- Precision Perforation: 12mm round holes with consistent spacing (typically 15mm pitch) ensure uniform flow and structural integrity.
- Standard Size: 4x8 feet (1220mm x 2440mm) fits standard frameworks and reduces cutting waste.
- ASTM A36 Compliance: Guarantees minimum yield strength of 250 MPa and tensile strength of 400-550 MPa for reliable performance.
- Versatile Surface Options: Available in black (as rolled) or hot-dip galvanized finish for corrosion resistance in outdoor or humid conditions.
- Easy Fabrication: Can be cut, welded, bent, or painted to meet specific project requirements.
- Wide Application: Used in construction (safety barriers, gratings), agriculture (grain dryer floors), mining (screens), and architecture (facade cladding, sunshades).

A: Sheets are bundled on wooden pallets, wrapped with waterproof paper and steel strapping to prevent damage during transit.
Q: Can I cut the sheet to smaller sizes?
A: Yes, the mild steel material is easy to cut with plasma, laser, or shearing tools. We can also provide pre-cut sizes at an additional cost.
Q: What is the typical lead time?
A: For standard specifications, lead time is 15-20 working days after order confirmation. Custom orders may require 25-30 working days.
Q: Does this sheet meet ASTM A36 specifications?
A: Yes, our material is tested and certified to comply with ASTM A36 mechanical properties, with a yield strength of 250 MPa minimum.
