High Carbon Steel Obstacle Fence – heavy-duty anti-intrusion security barrier for high-risk restricted areas and high-level defense. Made from phosphating steel wire with ultra-high tensile strength and surface hardness vs. soft low-carbon steel. Hard-drawing and welding process maximizes rigidity – mesh resists cutting, bending or breaking by tools or force. Dense small apertures with reinforced welds eliminate climbing gaps and weak points – solid physical obstacle system. Phosphating ensures stable performance and durability outdoors – reliable high-security barrier for critical restricted sites requiring strict intrusion protection.
Product Specification
The product adopts strict military and high-risk security grade specifications to meet top-level anti-intrusion demands. The steel wire tensile strength reaches no less than 1800MPa, far exceeding the strength of ordinary civil fence wires. The wire diameter ranges from 0.50mm to 0.90mm, forming an ultra-thick high-strength mesh body, which effectively prevents climbing, drilling and forced intrusion without protective dead angles. All wire intersections adopt fully reinforced high-pressure welding joints, ensuring no solder joint cracking or falling off under strong impact and shear force. The overall specification configuration focuses on structural firmness, anti-damage performance and long-term stability, fully complying with high-risk restricted area barrier standards.
Material
This high-strength obstacle fence adopts professional high-carbon steel raw material with a carbon content ranging from 0.45% to 0.8%, which fundamentally enhances the steel's hardness, tensile performance and shear resistance compared with conventional low-carbon steel. After multi-pass hard-drawing treatment, the high-carbon steel wire forms a dense and stable metal texture, delivering outstanding tool-resistant and anti-damage capabilities. To adapt to long-term outdoor and harsh industrial environments, the finished mesh panels undergo two upgraded anti-corrosion treatments
Product Application
With ultra-high structural strength, excellent anti-intrusion performance and harsh environment adaptability, high carbon steel obstacle fence is exclusively applied in high-security restricted scenarios. It is mainly used for military zone obstacle isolation to achieve closed and strict regional defense, mine restricted area fence to prevent unauthorized personnel and vehicle entry, prison auxiliary obstacle barrier to strengthen safety isolation and prevent escape, as well as chemical dangerous goods storage yard perimeter protection to isolate external risks and ensure site safety, providing top-level physical security defense for key high-risk sites.
Production Process
The product adopts rigorous high-strength standardized production procedures to guarantee top-grade barrier performance: firstly, conduct multi-pass hard-drawing treatment on high-carbon steel rods to refine metal texture and significantly boost wire tensile strength and hardness; secondly, adopt high-pressure automatic welding equipment to produce thick and dense mesh panels with reinforced solder joints; thirdly, complete surface pickling and impurity removal, followed by heavy hot-dip galvanizing or ZnAl alloy anti-corrosion treatment; fourthly, carry out batch tensile destructive testing to ensure all products meet strength standards; finally, adopt reinforced pallet packaging to prevent collision damage during long-distance transportation and ensure intact product delivery.
Precaution for Use
The high-hardness steel wire and reinforced welding structure have strong rigidity, so avoid violent impact and heavy extrusion during installation to prevent local structural stress concentration. Professional cutting tools are required for on-site size adjustment, as ordinary tools cannot cut the high-carbon steel wire. Keep the fence vertically and firmly installed with reliable fixing accessories to give full play to anti-intrusion performance. Regularly check welding joints and coating integrity for long-term outdoor use, and repair damaged coatings timely to avoid local corrosion diffusion.
Compare with Other Products
Compared with ordinary low-carbon steel fences, high carbon steel obstacle fence has several times higher tensile strength and hardness, with excellent anti-cutting, anti-bending and anti-vandalism capabilities, reaching professional security barrier grade. Different from common galvanized and PVC coated civil fences focused on basic isolation, it prioritizes anti-intrusion and anti-damage performance for high-risk scenarios. Though higher in cost and heavier in weight, its ultra-high structural stability and long service life make it irreplaceable for military, prison and dangerous goods yard high-security protection projects.
