What are Perforated Sheets?
Perforated sheets are flat metal panels with a pattern of holes punched through them using CNC punch presses. The hole pattern, size, and pitch determine the open area percentage, which controls airflow, visibility, sound absorption, and filtration properties.
The most common pattern. Available in staggered (60-degree) and straight-line configurations. Offers consistent open area and structural integrity.
Provides higher open area than round holes at the same pitch. Used where maximum flow or visibility is required, such as screens and guards.
Decorative and functional patterns including slotted, hexagonal, and ornamental designs for architectural and OEM applications.

Frequently Asked Question
Trusted in more than 100 countries and 4 million customers.
We stock round hole and square hole perforated sheets in SS304, MS HR, GI, and CRCA. Round hole in 60-degree staggered pattern is the most commonly available. Custom patterns can be manufactured to order.
Yes. We supply standard sheet sizes as well as roll-cut pieces to your exact dimensions. Roll-cut (SQM) format is available for long runs and allows custom width and length.
We stock up to 10 mm thickness in MS HR. SS304 is commonly available up to 3 mm. Thicker gauges can be sourced on request.
For round holes in 60-degree staggered pattern: Open Area (%) = (PI / (2 x SQRT(3))) x (D/P)^2 x 100, where D = hole diameter and P = pitch. We also provide an open area calculator on our website.
Finishing is available on request. Standard supply is mill finish. For architectural applications, we can arrange powder coating, anodising, or PVD coating through our finishing partners.
