Stainless Steel Small Hole Expanded Metal

Our stainless steel small-hole expanded metal mesh boasts extremely high manufacturing precision. It undergoes meticulous stamping and stretching processes. These advanced manufacturing technologies play a crucial role in ensuring the uniform size of the small holes on the mesh surface. The tight structure of the mesh surface is the result of these processes, and it also ensures that there are no loose threads that could affect the integrity of the product.

We use top-grade 304 or 316L stainless steel plates. The selection of these high-quality materials endows the mesh with a number of excellent properties. Its outstanding corrosion resistance means that it can stand the test of time even in humid environments or environments with the risk of acid-alkali corrosion. The high-strength characteristic of the mesh surface ensures that it can withstand large pressure and stress without being easily deformed. Despite its high strength, it is lightweight, making it easy to transport and install. In addition, its good ventilation performance allows air or fluid (depending on specific application scenarios) to pass through smoothly.

Thanks to its excellent material properties and compact structural design, this product is widely used in various high-demand scenarios. In the food and pharmaceutical industries, it can be used as precision filter screens and sanitary protection nets; in the chemical and marine fields, it can serve as corrosion-resistant protection nets and filtering components. Moreover, it is also suitable for protective covers of medical equipment, architectural decorative panels, and ventilation nets of electronic devices, perfectly meeting the requirements for hygiene, corrosion and rust resistance, and fine protection in all these scenarios.

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.
