Aluminum Decorative Expanded Metal

Aluminum Decorative Expanded Metal is a lightweight, high-performance decorative and architectural material, precision‑manufactured from high‑grade aluminum alloy. It offers excellent corrosion resistance without coatings, maintaining a brand‑new appearance for a long time. Its outstanding formability allows complex patterns, while its light weight simplifies installation and reduces structural load. The surface can be anodized or powder‑coated in various colors, greatly expanding design possibilities while retaining metal recyclability.

Using a CNC one‑step cold expansion process, solid aluminum alloy sheets are slit and stretched into seamless diamond, hexagonal or custom‑shaped openings, creating dynamic visual effects through unique light and shadow interplay. It supports anodizing, colorful powder coating or brushing to meet diverse design requirements.

Widely used in lightweight building facades, modern interior partitions, commercial display systems, rail transit interiors and outdoor landscape installations, it minimizes structural load while maximizing creative expression, combining industrial practicality with modern aesthetics for long‑term reliable performance. A full range of thicknesses and mesh specifications is available to meet fully customized project needs.

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.
