Stainless Steel Expanded Metal Mesh

Product Introduction

Stainless Steel Expanded Metal Mesh is a versatile industrial material manufactured from a single sheet of stainless steel. It is simultaneously slit and stretched to create a diamond-shaped pattern of openings. This process results in a rigid, one-piece construction that is stronger than wire mesh or perforated metal, as there are no joints or welds to fail.

Material (Grade)

Standard Grade: SS304, SS304L

Corrosion-Resistant Grade: SS316, SS316L (Ideal for marine or chemical environments)

Other Grades: SS310, SS321 (Available upon request)

FAQ

Q1: Is it stronger than wire mesh?

A: Yes. Because it is made from a single sheet of metal without welding points, it is structurally stronger and will not unravel if cut.

Q2: Can it be painted or powder coated?

A: Absolutely. While stainless steel is naturally corrosion-resistant, it can be powder coated for specific color matching or additional protection.

Q3: What is the difference between "Flattened" and "Standard" expanded metal?

A: Standard (Raised): The strands are left at an angle, providing a skid-resistant surface.
Flattened: The metal is passed through a cold roll reducer to flatten the strands, creating a smooth, flat surface with uniform thickness.

Q4: Do you offer custom sizes?

A: Yes, we specialize in custom manufacturing. We can cut sheets to your exact dimensions or fabricate panels with bending or welding.
