Carbon Steel Expanded Metal Grating

We select high-quality low-carbon steel, which is integrally formed from a whole thick steel plate through CNC stamping + stretching and expanding processes, with no welding points and a continuous structure. The surface treatments mainly include hot-dip galvanizing (mainstream anti-corrosion), electro-galvanizing, and powder coating.

Core Advantages:Strong anti-slip performance: Three-dimensional ridges form an uneven surface, making it not easy to slip in rainy, snowy, oily, or greasy environments;High opening rate: Fast drainage and mud discharge, reducing water accumulation and icing;High strength-to-weight ratio: Higher load-bearing capacity than flat plates/welded gratings of the same weight, with overall resistance to deformation and shear;Maintenance-free, long service life, and no risk of welding point detachment;Good ventilation and lighting, which can reduce wind resistance.

Typical Application Scenarios:Industrial field: Factory operating platforms, stair treads, equipment maintenance walkways, foot nets for oil tankers/chemical tankers, mine roadway platforms;Transportation infrastructure: Bridge maintenance channels, expressway anti-glare nets, dock boarding ladder treads;Construction and municipal engineering: Scaffold planks, steel structure platforms, drainage ditch covers, stadium fences;Special environments: Sewage treatment plants, coastal platforms, anti-slip treads in food/pharmaceutical workshops.

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.
