Aluminum Standard Expanded Metal

Aluminum small-hole expanded mesh is a lightweight, corrosion-resistant, and versatile metal mesh product. It is mainly made of high-quality 1050 pure aluminum or 3003 aluminum alloy - these two materials are widely recognized for their excellent corrosion resistance. They do not require additional coatings and can be used for a long time in various environments.

The production process follows strict precision manufacturing standards: first, high-quality aluminum plates undergo surface degreasing and annealing treatment, then are formed using custom molds through CNC precision stamping and stretching processes. This advanced manufacturing technology creates a small-hole structure with dense and evenly distributed apertures. The entire production process has no welded joints, ensuring that the mesh retains the inherent overall structural stability of aluminum while maintaining a smooth and flat surface.

This product is widely used in multiple fields. In the field of architectural decoration, it is suitable for making exquisite sunshades, interior and exterior decorative panels, ceilings, and ventilation curtain walls, especially in scenarios that have high requirements for fine surface texture and modern aesthetic design. In the field of filtration and screening, it can be made into precision filters for the food and beverage industry, air and liquid filters, as well as protective covers for precision electronics and audio equipment. In the professional industrial field, it can be used as lightweight shielding components, partitions in clean rooms and electronic manufacturing workshops, and is also suitable for producing industrial parts with strict requirements for spark-free characteristics. In the design and retail industries, it can be processed into display decorative panels, characteristic background walls, and various creative design components, giving full play to its excellent formability and smooth and delicate surface texture.

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.
