Stainless Steel Decorative Expanded Metal

Stainless Steel Decorative Expanded Metal is a high-end, multi-functional decorative material precision-manufactured from premium 304 and marine-grade 316 stainless steel. It features natural corrosion resistance, food-grade safety, and long-lasting metallic luster, with no need for additional protective coatings.

The product adopts a CNC-integrated cold expansion process: solid sheets are precisely slit and expanded to form a seamless, weld-free integrated mesh, eliminating fragile welded joints that affect strength and visual consistency. Custom patterns including diamond, hexagonal, and exclusive artistic designs are available. The expansion process maintains the structural integrity of stainless steel while creating creative forms, ensuring strength without welding or splicing. Its surface can be processed by mirror polishing, matte brushing, and other finishes, expanding design possibilities to meet diverse requirements.

This product is widely used in coastal building facades, high-end catering spaces, luxury retail interiors, medical clean rooms, yacht partitions, and public art installations, perfectly integrating artistic expression with industrial durability. A variety of thicknesses and mesh specifications are provided to fulfill customized project demands.

Other sizes are available upon request. For larger sizes, reinforcement is required to prevent expanded metal panels from sagging. For expanded metal panel with mesh bending frame, the mesh width shall be equal to the panel width; for expanded metal panel with angle steel frames, bending shall be considered, so the mesh width shall be 4–5 cm smaller than the panel width. Frame size: aluminum angle: 30 × 30 × 2 mm (thickness); hang-in angle: 30 × 30 × 2 mm (thickness); for panels larger than 1200 × 2000 mm, 3 mm thick is recommended.

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.
