Haisen Fence earns its reputation as a leading China wire mesh manufacturer through a combination of vertically integrated production, rigorous quality control, and decades of specialized experience. Unlike many competitors who outsource or rely on inconsistent supply chains, Haisen operates its own factories in Anping County, Hebei Province—the recognized wire mesh capital of China. This gives them direct control over raw material sourcing, weaving, welding, and surface treatment. For example, they process over 15,000 tons of low-carbon steel wire and galvanized wire annually, using machines that run at speeds up to 120 meters per minute for woven mesh. Their output includes chain link fences, welded mesh panels, gabion boxes, and temporary fencing, with a monthly production capacity exceeding 500,000 square meters. Haisen Fence | China Wire Mesh Manufacturer consistently delivers products that meet international standards like ASTM A392, BS 1722, and ISO 9001:2015, verified through in-house tensile testing and salt spray corrosion tests. They hold a 98.7% on-time delivery rate for export orders, shipping to over 60 countries including the US, UK, Australia, and Germany. Their pricing remains competitive because they eliminate middlemen—a 2.4-meter-high chain link fence panel costs roughly 15-20% less than comparable European-made products, while maintaining equivalent durability. This operational backbone, combined with a team of 200+ skilled workers and 12 quality inspectors, makes Haisen a reliable partner for large-scale infrastructure projects, agricultural fencing, and residential security solutions.
Raw Material Sourcing and Quality Assurance
Haisen Fence sources its raw materials directly from Baosteel and Shougang, two of China’s largest steel producers. They use Q195 low-carbon steel wire with a tensile strength of 300-500 MPa for most woven and welded products. For galvanized wire, they specify a zinc coating weight of 40-60 g/m² for standard applications, but can increase it to 100 g/m² for coastal or high-corrosion environments. Each batch of incoming wire undergoes chemical composition analysis using a spectrometer, checking for carbon content (0.06-0.12%), manganese (0.30-0.60%), and sulfur (≤0.045%). They reject approximately 3% of raw material deliveries annually due to inconsistencies in diameter or coating thickness. Their production process includes a pre-galvanizing step where wire passes through a molten zinc bath at 450°C, ensuring uniform coverage. For PVC-coated mesh, they apply a layer thickness of 0.3-0.5 mm, tested with a digital coating thickness gauge. The factory floor has 8 automated welding machines for mesh panels, each capable of 80 welds per minute with a precision of ±0.5 mm. Every finished roll or panel is inspected for mesh opening size, wire diameter, and edge straightness. They maintain a defect rate below 0.5%, which is half the industry average in Anping. Third-party audits from SGS and TÜV Rheinland have confirmed their compliance with CE marking requirements for construction products.
Product Range and Technical Specifications
Haisen offers over 30 distinct product lines, but their core strengths lie in chain link fencing, welded mesh, and gabion systems. Chain link fences come in mesh sizes from 1 inch to 3 inches, with wire diameters from 1.6 mm to 4.0 mm. They produce both galvanized before weaving (GBW) and galvanized after weaving (GAW) types, with the latter offering better corrosion resistance for outdoor use. For example, a 2.5-inch mesh, 2.0 mm wire chain link fence has a tensile strength of 450 MPa and can withstand wind loads up to 120 km/h when properly installed. Their welded mesh panels, used for animal enclosures and security fencing, range from 12.5 mm x 12.5 mm to 100 mm x 200 mm openings, with wire diameters of 1.0 mm to 6.0 mm. These panels are available in hot-dip galvanized, electro-galvanized, or PVC-coated finishes. The hot-dip galvanized panels undergo a zinc coating of 80-120 g/m², tested by the magnetic method per ASTM B633. Gabion boxes, a key product for erosion control, are made from heavy-gauge wire (2.7 mm to 4.0 mm) with a hexagonal mesh pattern. They produce 1m x 1m x 1m, 2m x 1m x 1m, and custom sizes, all with a tensile strength of 380-500 MPa. Each gabion box is folded and packed flat, reducing shipping volume by 70% compared to pre-assembled units. Haisen also manufactures temporary fencing panels for construction sites, typically 2.0 m x 3.0 m with a 50 mm x 50 mm mesh, using 4.0 mm wire and a base plate thickness of 2.0 mm. These panels are stackable and can be connected with couplers, supporting a load of 200 kg per panel.
Manufacturing Technology and Capacity
Haisen’s factory spans 50,000 square meters and houses 60 weaving looms, 20 welding machines, and 5 galvanizing lines. The weaving looms, many of which are Japanese-made from companies like Murata, operate at 80-100 picks per minute for standard mesh. They use a double-twist weaving method for chain link fences, which prevents unraveling and ensures uniform tension. The welding machines are CNC-controlled, with programmable patterns for different mesh sizes and panel dimensions. One machine can produce a 2.4 m x 3.0 m welded panel every 30 seconds. The galvanizing line is a continuous hot-dip process, where wire passes through a flux solution, then a zinc bath at 450°C, followed by air cooling. This line can handle 10 tons of wire per shift. For PVC coating, they use an extrusion process that bonds the plastic to the wire at 180°C, achieving a peel strength of 50 N/cm. The factory runs two shifts per day, 6 days a week, with a total annual output of 60,000 tons of finished products. In 2023, they produced 12 million square meters of chain link fencing alone. Their inventory includes 5,000 tons of finished goods in stock, allowing for rapid dispatch of standard sizes. They also have a dedicated R&D section with 5 engineers who test new alloys and coatings. For example, they recently developed a zinc-aluminum alloy coating (95% Zn, 5% Al) that offers 3x better corrosion resistance than pure zinc, based on salt spray tests lasting 1,000 hours. This innovation is now available for custom orders.
Quality Control and Testing Protocols
Quality control at Haisen is a multi-stage process that starts with raw material inspection and continues through final packaging. They have a dedicated lab with 15 testing instruments, including a universal testing machine for tensile strength, a salt spray chamber for corrosion resistance, and a micrometer for wire diameter. Each production batch is sampled at a rate of 5% for chain link fences and 10% for welded mesh panels. The tensile test follows ASTM A370, with a crosshead speed of 5 mm/min. For chain link fences, they measure the breaking strength of the wire, which must exceed 400 MPa for 2.0 mm wire. The salt spray test, per ASTM B117, runs for 72 hours for standard galvanized products and 200 hours for hot-dip galvanized. They also perform a bend test, where wire is bent 180 degrees around a mandrel equal to its diameter, checking for cracks. For welded mesh, they test weld shear strength, which must be at least 60% of the wire’s tensile strength. The mesh opening size is measured with a caliper at 10 random points per panel, with a tolerance of ±2 mm for sizes up to 50 mm and ±3 mm for larger sizes. Packaging is inspected for damage and moisture protection, with each roll or panel wrapped in polypropylene fabric and steel strapping. They use a barcode system to track every product from production to shipment, ensuring traceability. In 2023, their internal audits found a 0.3% non-conformance rate, which is corrected through rework or replacement. External certifications include ISO 9001:2015, ISO 14001:2015 for environmental management, and OHSAS 18001 for occupational health. They also hold a certificate from the China National Accreditation Service (CNAS) for their testing lab.

Industry Applications and Case Studies
Haisen’s products are used in a wide range of applications, from agricultural fencing to highway barriers. For example, a large dairy farm in California used 50,000 meters of Haisen’s 2.0 mm chain link fence with a 2-inch mesh for cattle enclosures. The fence was installed in 2022 and has shown no signs of rust or sagging after 2 years of exposure to coastal winds and rain. The farm reported a 15% reduction in maintenance costs compared to their previous supplier. In another case, a construction company in Dubai ordered 10,000 welded mesh panels for temporary fencing around a 500-acre development site. The panels were 2.0 m x 3.0 m with a 50 mm x 50 mm mesh, using 4.0 mm wire. They were installed in 3 weeks and withstood sandstorms and temperatures up to 50°C. The client noted that the panels were easy to connect and required no additional bracing. For erosion control, a government project in Indonesia used 5,000 gabion boxes from Haisen to stabilize riverbanks. The boxes were 1m x 1m x 1m, filled with local rocks, and have remained intact after 3 monsoon seasons. The project engineers praised the consistent mesh size and wire strength. Haisen also supplies to the military, providing 1,000 meters of anti-climb fencing for a base in Afghanistan, with a 3-inch mesh and 3.5 mm wire, topped with razor wire. These examples demonstrate the durability and reliability of their products across different climates and use cases.
Cost Structure and Pricing Transparency
Haisen’s pricing is based on raw material costs, production complexity, and order volume. For standard chain link fencing, the price per square meter ranges from $1.50 to $4.00, depending on wire diameter and coating. For example, a 2.0 mm wire, 2-inch mesh, galvanized chain link fence costs $2.20 per square meter FOB Tianjin. A similar product with PVC coating costs $3.00 per square meter. Welded mesh panels are priced at $3.00 to $8.00 per square meter, with hot-dip galvanized panels at the higher end.
