Aluminum Expanded Metal Grating

Aluminum Expanded Metal Grating is made from high-strength aluminum alloy sheets, featuring natural corrosion resistance, excellent strength-to-weight ratio and non-sparking properties. It is suitable for places with strict safety requirements.

The product adopts an integrated cold expansion process in production. By simultaneously slitting and stretching aluminum sheets, it forms seamless, weld-free diamond openings, eliminating fragile welded joints. The process naturally creates a raised anti-slip surface. The open mesh design allows efficient drainage and ventilation, and prevents debris accumulation.

This product is widely used in the following scenarios.Marine and coastal facilities: walkways and platforms requiring high saltwater corrosion resistance;Chemical and food processing: non-polluting flooring in wet working areas;Light industry: mezzanines and elevated walkways with low structural load requirements;Architectural decoration: decorative grilles, sunscreens and pedestrian bridges.

A variety of thicknesses and specifications are available to meet diverse project needs and ensure long-term maintenance-free operation.

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.
