As a professional fence manufacturer, the production process of spear top steel fence, is not only about the quality and durability of the product, but also the embodiment of our brand image and market competitiveness. This blog will analyze the Spear Top Fence process in detail.
In the production of spear top steel fence , the quality of raw materials is crucial. We strictly inspect the outer diameter and wall thickness of the pipes, which are usually between 20mm and 50mm in outer diameter and 1.5mm to 3mm in wall thickness to ensure that they meet international standards. Through this preliminary quality control, we ensure the reliability of the basic materials and facilitate subsequent production.
The inspected pipes will be accurately cut according to the design drawings. The cutting accuracy is controlled within ±1mm, the burr height after cutting is ≤0.1mm, and the inclination of the cut is ≤1°, ensuring that each component can be seamlessly connected during assembly. According to our statistics, accurate cutting can reduce assembly time by about 15% and improve production efficiency.
In order to facilitate assembly and welding, we need to punch the crossbeams and flatten the vertical pipes. This process ensures the correct alignment of the components and avoids deformation during welding. Our punching accuracy is controlled at ±0.5mm to ensure the structural integrity of the fence.
Welding is a key step in connecting fence components. We use single-sided and double-sided welding technology, with a weld length of at least 15mm and a welding strength of more than 80% of the international standard. According to tests, the quality of welding directly affects the durability of the fence, and qualified welding can extend the service life of the fence by 30%.
Sandblasting forms dense pits on the surface of the tube to improve the adhesion of the powder coating. After sandblasting, we use high-pressure cleaning equipment to remove residual metal powder to ensure the effectiveness of the coating. Studies have shown that sandblasting can improve coating adhesion by 50%.
 
The phosphating process deposits a dense phosphating layer on the surface of the workpiece to enhance corrosion resistance. The passivation process forms a protective film on the surface to further improve corrosion resistance. According to experimental data, the corrosion resistance of the fence after phosphating and passivation treatment has increased by 40%.
Powder coating provides a durable and beautiful coating for fences. We use electrostatic spraying technology, and the coating thickness is controlled between 60μm-100μm to ensure its durability in various environments. Data shows that the anti-rust performance of powder-coated spear top steel fence can reach more than 10 years.
Quality is the life of an enterprise. We conduct strict quality inspections on each batch of fences: including powder coating tests, load tests, impact tests and weathering tests. Each batch of products must pass these rigorous tests to ensure its beauty and structural durability. We conduct more than 500 quality inspections every year to maintain our industry leadership.
Packaging is an important part of ensuring that the finished product is not damaged during transportation. We use non-stick plastic film to isolate the panels and use wrapping film, steel frames, strapping and pallets for overall packaging. Our packaging design is optimized to reduce the transportation damage rate to less than 1%.
