what is AISI 304L Stainless Steel Perforated Sheet?
AISI 304L stainless steel perforated sheet is a flat sheet made from low-carbon austenitic stainless steel (304L grade) with a regular pattern of holes punched into it. It offers excellent corrosion resistance, strength, and a good strength-to-weight ratio, making it ideal for construction, food processing, filtration, and industrial applications requiring ventilation, drainage, or decorative features. The "L" indicates its low carbon content, which improves weldability and prevents sensitization (carbide precipitation) during welding.

FAQ
1️⃣ What does 3000/1500 mesh mean in a perforated plate?
It refers to the number of holes per unit area, providing fine filtration or ventilation, depending on your application.
2️⃣ What is R8T12 punching?
R8T12 is the punching pattern type, defining hole size, shape, and spacing, ensuring consistent flow and uniform perforation.
3️⃣ Can these 304L perforated plates be welded or processed?
Yes. Being low-carbon SUS304L, they are ideal for welding, cutting, and machining without significant corrosion risk at welded seams.
4️⃣ What thickness and sizes are available?
Thickness: 0.5 mm – 6 mm, Width: up to 1500 mm. Custom sizes can be cut to order for your specific project.
