1. Product Description Expanded wire mesh (expanded metal) is produced by simultaneously slitting and stretching a solid metal sheet in one continuous, chipless process, forming a diamond-pattern mesh with no joints or welds. The result is a lightweight yet rigid mesh offering a high strength-to-weight ratio, excellent ventilation, and anti-slip surfaces. Bolin supplies expanded mesh in a broad range of materials and dimensions for architectural, industrial, and security applications. 2. Available Materials Stainless Steel: 304 / 304L / 316 / 316L / 2205 / 2507 | Nickel | Aluminium | Titanium | Copper | Silver (special materials on request) 3. Key Features • One-piece formed — no joints or welds: inherently strong and uniform • Lightweight: weighs only 40–60% of the original solid sheet, reducing material and shipping cost • Anti-slip surface: diamond-pattern edges provide natural grip for walkways and treads • Ventilated and transparent: open area engineered to balance strength and airflow/light • Excellent workability: can be cut, bent, stamped, or roll-formed into complex shapes 4. Applications • Architecture: curtain wall cladding, balustrades, stair treads, suspended ceilings • Industrial: machine guards, platform grating, ventilation covers • Mining and screening: ore grading screens • Security: perimeter fencing, anti-theft screens, protective barriers • Agriculture and aquaculture: enclosures, gratings • Marine and offshore: deck grating, anti-slip treads 5.
