Carbon Steel Standard Expanded Metal

Standard expanded metal, also referred to as raised expanded metal, is manufactured by slitting and stretching metal sheets or coils simultaneously.

It boasts a surface with raised diamond-shaped openings, and its raised strands form an angle relative to the original plane of the solid sheet-this design enhances the product's strength, rigidity, and anti-skid performance significantly.Owing to these superior properties, it finds extensive applications across numerous fields, such as road fences, platforms, stair treads, and machine guarding.

We offer a wide range of standard expanded metal products crafted from high-quality materials, including carbon steel, galvanized steel, and aluminum. This ensures our products deliver optimal performance and long-lasting durability. Furthermore, we are committed to collaborating with you to develop custom expanded metal solutions tailored to your specific application needs through in-depth communication.
