Mono strand barbed wire consists of a single galvanized steel wire with four-point barbs twisted at regular intervals. It complies with ASTM A641 (low-carbon) or ASTM A121 (high-tensile) standards. Common applications include farm boundaries, highway medians, and security perimeters where a lighter yet effective barrier is needed.

FAQ
Q1: What is the maximum roll length without a splice?
For 2.0 mm wire, we can produce up to 500 m continuous length without any splice. For 2.8 mm, maximum is 300 m.
Q2: Do you offer stainless steel mono strand barbed wire?
Yes, with grade 304 or 316. The barbing process is the same, but the tensile strength is around 700–800 MPa.
Q3: How long does hot‑dip galvanized mono strand last in a marine environment?
Typically 10–15 years. For longer life, add a PVC coating or use 316 stainless steel.
