Galvanized Steel Decorative Expanded Metal

Galvanized Decorative Expanded Metal is made of high-quality carbon steel, featuring an attractive visual effect and excellent durability.

In the production process, carbon steel sheets are first precision-expanded into diamond, hexagonal or custom-shaped openings to form a seamless mesh surface with unique light and shadow effects. The mesh is then hot-dip galvanized to form a protective zinc coating, ensuring long-term corrosion resistance while fully retaining the decorative texture, making it suitable for harsh outdoor environments.

This product is ideal for both interior and exterior applications: architectural decoration such as facade panels, balcony railings and sunshades for high weather-resistance requirements; landscape facilities including garden screens, trellises and outdoor art installations; commercial interiors like decorative partitions, ceiling panels and retail displays; as well as security and aesthetic uses such as decorative window guards and entrance doors.

Specifications and mesh sizes can be customized according to customer requirements, and a variety of surface treatments are available to meet diverse design needs.

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.
