Details
Wire mesh is a versatile and widely used material composed of interlocked or woven wires forming a grid-like pattern. It offers varying degrees of strength, durability, and corrosion resistance. Available in an array of shapes, sizes, and configurations, wire mesh finds application across diverse industries, including construction, agriculture, manufacturing, and art. Its uses range from reinforcing concrete and providing structural support in construction to serving as protective barriers, filtration systems, animal enclosures, and even artistic installations. The flexibility, strength, and adaptability of wire mesh make it an indispensable component in numerous practical and creative endeavors.
