Carbon Steel Decorative Expanded Metal

Carbon Steel Decorative Expanded Metal is precision-made from high-quality low-carbon steel. Through a professional expansion process, solid carbon steel sheets are precisely slit and stretched to form diamond, hexagonal or custom-designed mesh structures, creating an integrated seamless surface with unique visual effects, combining structural practicality and aesthetic appeal.

This product features excellent formability, processability and stable mechanical properties. It is compatible with various surface treatments such as powder coating, painting and antique finishing to meet diverse design requirements. Its open structure creates creative light, shadow and transparency effects while ensuring durability and ventilation.

It is mainly used for architectural and interior space enhancement. Facade decoration and sunscreens: adding rich texture while adjusting light penetration;Interior partitions and ceilings: defining space with decorative transparency;Commercial displays and furniture: providing modern design elements for commercial environments; Landscape and garden facilities: used as trellises, screens or artistic installations.

Available in a variety of patterns and thicknesses, this product is an ideal material for designers to integrate industrial texture with modern aesthetics, achieving a balance between visual effect and practical performance.

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.
