Carbon Steel Flattened Expanded Metal

Carbon Steel Flattend expanded metal mesh is a cost-effective and high-strength metal mesh product. Carbon steel plates are cut and stretched using professional equipment to form primary expanded mesh with diamond-shaped holes, which is then subjected to high-pressure flattening treatment. This process can make the mesh surface smooth, remove sharp edges, improve structural uniformity, and ensure that the mesh sheet, while maintaining overall strength, is easier to install and reprocess.

This product is made of high-quality Q195/Q235 carbon steel, benefiting from the excellent tensile strength, structural rigidity, and cost-effectiveness of this material. It inherits the inherent sturdiness of carbon steel and is suitable for heavy-duty operations as well as general protection scenarios that require both high strength and economy.

In the industrial field, it is very suitable for use in mezzanine floors, walkways, and stair treads. It can not only meet the safety and comfort requirements of walking surfaces but also retain the drainage and light transmission properties of the mesh sheet. In the mechanical field, it can be made into machine guards with strong protection and durability, featuring a clean and attractive surface, while ensuring unobstructed visibility and air circulation. In the logistics and transportation field, it is used for truck bed floors, trailer linings, and conveyor guards, and its flat surface facilitates the smooth movement of goods and equipment. In the architectural decoration field, its smooth surface makes it suitable for wall cladding, decorative screens, and signage.
