The superior performance of our prison security fencing begins with strictly selected raw materials . We primarily use high-quality low-carbon steel wire as the core material for the mesh body , which offers an excellent balance of toughness, malleability, and weldability. After being processed through a cold-drawing technique, the tensile strength of the steel wire is significantly increased, providing the foundational resistance against impact and cutting for the entire fence . The posts and frame are constructed from high-strength rectangular steel tubes or angle steel, serving as the robust “skeleton” of the protective system to ensure structural integrity under force without deformation or collapse . The razor wire at the top is precision-punched from galvanized steel sheets or stainless steel plates, ensuring each blade is sharp and uniform, creating an effective psychological deterrent and physical barrier. All metal materials undergo strict chemical composition and mechanical property testing before being put into use . Advanced manufacturing processes are key to transforming premium raw materials into high-security products . For the mesh panels, we employ fully automated resistance welding technology. Computer-controlled welders ensure every intersection point is welded firmly and uniformly, with high tensile strength at the weld points, eliminating false or missed welds . Cutting and punching for posts and frames are performed using CNC plasma cutting and punching machines, guaranteeing dimensional accuracy and the precise positioning of mounting holes, laying the foundation for fast and accurate on-site installation. The distinctive razor barbed wire is manufactured using specialized equipment that securely winds sharp blades onto a high-tensile core wire, forming helical or straight lines. The connection points can withstand immense pulling force without detachment . The entire manufacturing process operates under an ISO quality management system, with inspection at each stage to ensure consistency and reliability from the inside out . For security facilities permanently exposed to the elements, anti-corrosion capability directly determines their effective service life . We offer multiple proven surface treatment solutions, specifically designed to withstand harsh Southeast Asian environments like Vietnam’s high temperature, humidity, and salt spray  is the preferred process. Workpieces are immersed in a molten zinc bath at temperatures above 450°C, forming a dense, uniform zinc-iron alloy layer. This provides excellent cathodic protection and mechanical defense, with a service life exceeding 20 years . Powder Coating / PVC Coating involves applying a layer of polyethylene (PE) or polyvinyl chloride (PVC) coating over 0.8mm thick onto the workpiece surface. The coating is tough, color-fast, and offers excellent resistance to acids, alkalis, and UV degradation. Spray Coating (Electrostatic Spraying) allows for a wider range of color options and a smooth, aesthetically pleasing finish . Dual Protection System: Galvanizing + Coating  combines the electrochemical protection of the zinc layer with the physical barrier of the plastic coating, offering ultimate protection for facilities in extreme environments.
