WELDED WIRE MESH FENCING PANELS

Welded meshes are supplied in galvanized and powder paint/ coated finish. Weld mesh panel can be used with steel palisade to form a stronger fencing texture, a dual fencing panels with both steel bar railing and mesh partition. The mesh netting welded also makes a popular secure fencing material for airport, road, residences, prison, garrison and borders.

Security Weld Mesh Panelling

Weld mesh partition is used with palisade fence and many other fencing materials to provide additional anti-cutting, anti-climbing features. Normally, welded mesh of galvanized finish works with steel fencing of same finish.
