Diamond-shaped wire mesh, also known as diamond-shaped chain link mesh, is a mesh structure made of low-carbon steel wire, stainless steel wire, or aluminum alloy wire through a hook-and-weave process. Surface treatments include electro-galvanizing, hot-dip galvanizing, and plastic coating. It features uniform mesh size, a flat surface, corrosion resistance, and structural stability. It is mainly used in highway and railway guardrails, stadium fencing, machinery protection, and flood control projects (such as gabion reinforcement of embankments).
