Frequently Asked Questions
Q1 What materials are available for perforated sheets?
Perforated sheets can be manufactured from stainless steel (grades 304, 316, 316L), carbon steel, galvanized steel, aluminum, brass, and copper, depending on corrosion resistance, weight, and application requirements.
Q2 What hole patterns and configurations can be produced?
Standard hole configurations include round (staggered or straight line), square, slotted, hexagonal, and decorative patterned holes, with variable pitch, hole diameters, and open area percentages.
Q3 Can custom sheet dimensions and non-perforated margins be provided?
Yes, custom cut-to-size dimensions, specific blank margin widths along edges, laser cutting, bending, and specialized hole configurations are fully customizable based on technical drawings and engineering specifications.
Q4 What surface finishes and treatments can be applied?
Available surface treatments include mill finish, powder coating, anodizing (for aluminum), hot-dip galvanizing, electro-polishing, and PVDF coating to enhance weather resistance, durability, and aesthetics.
Q5 What are the primary applications of perforated metal panels?
Common applications include architectural facade cladding, acoustic ceiling panels, sunscreens, protective equipment guards, filtration screens, ventilation grilles, interior partitions, and balustrade infill panels.
Q6 How do I calculate and select the right open area percentage?
The open area percentage is determined by the hole diameter and center-to-center pitch distance. It influences fluid filtration efficiency, airflow ventilation, light transmission, and the remaining structural strength of the sheet.
