Huaxia-Steel manufactures carbon steel perforated sheets with precision CNC punching and laser cutting capabilities. Our perforated sheets feature uniform hole patterns, clean edges, and consistent open area ratios. Available in round, square, slotted, and decorative patterns, we serve filtration, architecture, machinery guarding, and acoustic panel industries worldwide.
Product Overview
Carbon steel perforated sheet is a versatile metal product with regularly spaced holes created by punching or drilling. It offers strength, ventilation, visibility, and aesthetic appeal in a single material. Perforated carbon steel is cost-effective compared to stainless alternatives and accepts various surface treatments including powder coating, galvanizing, and painting.

Available Materials
- ASTM A36 / Q235B: General purpose, cost-effective
- Q345B / S355JR: Higher strength, structural applications
- SPHC / SPHD: Cold-forming quality for deep draws
- Galvanized: Hot-dip galvanized before or after perforating
Manufacturing Standards
Perforation is performed on CNC turret punch presses or fiber laser cutting machines depending on pattern complexity and thickness. Hole diameter tolerance is 0.05mm for standard patterns. Sheet flatness is maintained within 3mm per meter. For architectural applications, we offer deburred edges and brushed finishes.
Applications
- Air and liquid filtration systems
- Architectural facades and sunshades
- Machine guards and safety screens
- Acoustic panels and ceiling baffles
- Ventilation grilles and diffusers
- Grain drying and sorting equipment
- Automotive grilles and trim
Quality Assurance
Each batch is inspected for hole diameter accuracy, pitch consistency, open area percentage, and sheet flatness. Thickness is measured with micrometers at multiple points. For coated sheets, coating thickness is verified per ASTM D7091.
Packing and Shipping
Sheets are stacked horizontally on wooden pallets with paper interleaving to prevent surface scratching. Edges are protected with U-channel or corner guards. For thin sheets (under 2mm), vacuum packaging prevents transit damage. Container loading uses proper bracing to prevent shifting.
