Our razor wire, also known as razor ribbon or concertina wire, is a high-security fencing topping designed to prevent unauthorized climbing and intrusion. Manufactured from high-tensile galvanized steel core wires with sharp, razor-sharp barbs, this product creates a formidable psychological and physical barrier. The barbs are tightly clenched onto the core wires to prevent sliding and shifting, ensuring long-term effectiveness. Available in various coil diameters and barb spacings, our razor wire can be installed in single or multiple coils on top of walls, fences, and perimeters. The hot-dip galvanized finish provides excellent corrosion resistance against tropical humidity and coastal salt spray, making it ideal for prisons, military bases, power plants, airports, and high-security industrial facilities across Southeast Asia. For added visibility and longer service life, we also offer PVC-coated options in green or yellow.
