Galvanized Steel Small Hole Expanded Metal

Galvanized steel sheet small hole expanded mesh is a type of metal mesh product with extremely high strength and wear resistance, suitable for various harsh industrial operations and outdoor application environments. We use high-quality carbon steel billets, which are precisely formed and then subjected to advanced hot-dip galvanizing treatment - this post-treatment process applies a uniform thickness of zinc layer to all parts of the mesh, from the main wires to the tiny hole edges, and the zinc layer is tightly bonded with the steel substrate, integrating into one.

This product has high structural toughness and wear resistance: the solid carbon steel substrate has excellent tensile and compressive strength, and can effectively resist deformation and fracture even under continuous heavy loads and friction. The galvanized layer not only forms an anti-seepage barrier to resist rust, corrosion and chemical erosion, but also significantly improves the surface hardness of the mesh, further enhancing its wear resistance. This greatly extends the service life of the product in high-wear environments without affecting its core mechanical properties at all.

Production Workflow

Raw material

Our raw material steel plates are supplied by recognized companies such as Baosteel and Shougang Group. When the materials arrive, our quality control team performs detailed testing on chemical composition, dimensions, and related specifications to guarantee they meet or surpass quality requirements.

Stamping

Our company is equipped with advanced 4000 mm ultra-wide expanded metal manufacturing machines, as well as flattening and leveling equipment. We have developed and accumulated more than 1,000 types of precision molds for expanded metal, allowing us to satisfy customer demands for larger-sized materials. We can also select or customize new mesh patterns to meet requirements related to strength, appearance, ventilation, and shading.

Flattening

Our workshop is equipped with comprehensive deep-processing machinery such as cutting, flattening, bending, and welding equipment. With these capabilities, we can deliver customized processing solutions for expanded metal products to meet diverse application needs.

Leveling

Using high-precision leveling machinery, we ensure that the mesh surface remains flat, with evenly distributed openings and superior flatness tolerance. With many years of expertise and multiple CNC leveling machines, our skilled team optimizes operational parameters to maintain high productivity and consistent product quality.

Surface treatment

Our company offers a comprehensive range of surface treatment solutions, such as galvanizing, powder coating, anodizing, and PVDF coating. These finishes provide excellent durability and an appealing appearance for both functional and decorative uses.

Quality inspection

During manufacturing, our technical staff closely monitor processes such as punching, flattening, shearing, and leveling. This ensures that product quality can be evaluated continuously while also allowing us to detect and improve any weaknesses in the production process.

Packaging

Our packaging solutions are designed according to the chemical and physical properties of the products. Waterproof, moisture-resistant, and protective materials are used to minimize the risk of damage during shipping. We also offer customized packaging to meet individual customer specifications.
