Lianxin is a professional manufacturer of Expanded Metal Mesh products, offering high-quality solutions for industrial, commercial, architectural, and security applications. Expanded Metal is produced by slitting and stretching metal sheets to form diamond-shaped openings, creating a single-piece mesh without welds. This structure ensures excellent strength-to-weight ratio, rigidity, and long-lasting performance, making it ideal for walkways, enclosures, guards, screens, facades, and fencing. Expanded Metal is widely used for ventilation, drainage, filtration, reinforcement, and design features in infrastructure, construction, and equipment manufacturing. Available in raised (standard) or flattened types, our Expanded Metal Mesh comes in a variety of materials, opening patterns, and surface finishes to suit specific project needs.



Materials for Expanded Metal Mesh
Lianxin manufactures Expanded Metal Mesh using a variety of high-performance materials:
- Low Carbon Steel – Cost-effective, strong, suitable for general industrial applications. Can be galvanized for rust protection.
- Galvanized Steel – Steel with zinc coating for corrosion resistance in outdoor and high-moisture environments.
- Stainless Steel (304, 316) – Excellent for harsh or hygienic environments due to corrosion resistance.
- Aluminum and Alloys – Lightweight, rust-resistant, and ideal for architectural panels or decorative use.
- Copper, Brass, Nickel – Applied in specialized or decorative projects requiring aesthetic or conductive properties.
Surface Treatments of Expanded Metal
To enhance appearance and durability, Lianxin offers a variety of surface finishes:
- Hot-dip Galvanizing – Thick zinc coating for corrosion resistance.
- Electro-galvanizing – Smooth zinc layer suitable for light-duty use.
- Powder Coating / Painting – Custom RAL colors available for decorative or protective finishes.
- PVC Coating – Adds insulation, impact resistance, and color.
- Anodizing (Aluminum) – For corrosion resistance and architectural aesthetics.
Types of Expanded Metal Mesh
- Light Expanded Metal – Thin gauge mesh for vents, screens, and small enclosures.
- Medium Expanded Metal – Ideal for guards, partitions, and fencing panels.
- Heavy-Duty Expanded Metal (Grating) – For walkways, catwalks, and industrial platforms.
- Raised Expanded Metal (Standard) – Rigid and skid-resistant with elevated strands.
- Flattened Expanded Metal – Cold-rolled mesh with a smooth surface, suited for framing and mounting.
- Architectural & Decorative Mesh – Custom patterns and coatings for facades, interiors, and design features.
Expanded Metal Mesh Applications
