FAQ

1.What is expanded mesh?
Expanded mesh is a metal product made by simultaneously slitting and stretching a solid metal sheet or coil. This process creates a diamond-shaped opening pattern. Unlike welded or woven mesh, expanded mesh has no joints or seams because it comes from a single piece of metal.

2.What materials are used for expanded mesh?
Common materials include galvanized steel, stainless steel (304 and 316), aluminum, carbon steel, copper, brass, and titanium. Stainless steel 316 is recommended for marine or highly corrosive environments. Aluminum is lightweight and rust-proof, making it suitable for architectural and decorative applications.

3.What are the standard mesh sizes and sheet dimensions?
Mesh openings range from very fine (0.5mm) to heavy-duty (100mm+). The opening size is defined by SWD (short way of diamond) and LWD (long way of diamond). Standard sheet sizes include 1x2m, 1.22x2.44m (4x8 feet), and 1.5x3m. Custom sizes are available.

4.What thicknesses are available?
Material thickness typically ranges from 0.3mm to 8.0mm. Thin sheets (0.3-1.0mm) are used for fine mesh and decorative applications. Thick sheets (2.0-8.0mm) are used for heavy-duty walkways, safety grating, and security screens.

5.What is the difference between expanded mesh and perforated metal?
Expanded mesh is made by stretching slotted metal, creating raised diamond openings with no material loss. Perforated metal is made by punching holes into a flat sheet, which removes material and leaves flat openings. Expanded mesh is generally stronger and lighter for the same gauge. Perforated metal offers a flatter surface and more uniform appearance.

6.What are the main applications of expanded mesh?
Safety grating and walkways, machine guards and safety barriers, security fencing and window screens, architectural facades and sun shades, shelving and storage racks, filtration and sieving, animal cages and enclosures. The one-piece construction makes it stronger than welded or woven mesh of equivalent weight.
