Road traffic poles are an important infrastructure element of municipal roads whose manufacturing process directly determines their durability, safety and life span. Well-known manufacturer Qixiang use standardized assembly line processes with strict control at each step, from raw material selection and cutting/welding, to galvanizing and powder coating. The complete manufacturing process not only improves the structural strength, corrosion resistance and wind resistance of the traffic light steel poles, but also ensures the high-quality appearance, meeting the long-term outdoor use requirements of various municipal projects.
I. Full Manufacturing Process of Road Traffic Poles
The production process of good-quality municipal road traffic poles is standardized and strictly controlled from the selection of raw material up to the delivery of the finished product at every stage. This process mainly includes six core steps to ensure the pole quality is stable and durable.
1. Cutting and Raw Material Selection
Select high-quality national standard low-carbon steel pipes and galvanized steel pipes as raw materials, with high thickness and toughness. We use professional CNC equipment to perform precise cutting according to the customer’s needs and project specifications, controlling the length and diameter of the traffic light steel poles to eliminate errors and ensure the uniformity of the pole foundation.
2. Bending and Welding
The pipes are bent in one piece by huge bending machines and get standard shapes like uprights, cantilever arms and overhead arms. The joints are full welded, with smooth full welds, free of porosity or incomplete welds. With the grinding, burrs and sharp edges are taken away, making it a smooth, clean look with a more stable structure.
3. Pickling and Rust Removal
After welding, professional pickling, degreasing and rust removal treatments are carried out to thoroughly remove rust, oil and oxide layers on the surface of the traffic light steel poles, and purify the surface of the substrate. This process lays the groundwork for future anti-corrosion treatments, avoiding problems like delamination and rust down the line.
4. Hot-Dip Galvanizing
This is the primary anti-corrosion method. The purified poles are dipped into the high temperature zinc liquid for overall hot-dip galvanizing, so that the traffic light steel poles can get a complete zinc coating inside and out with no dead corners, effectively isolating the poles from the corrosion of air and rainwater.
5. Powder Coating
After galvanization, powder coating is applied by high quality outdoor powder coating. The powder is sprayed evenly on the surface of the poles and baked at high temperature to ensure tight adhesion between the coating and the substrate.
6. Careful Quality Inspection and Packing
Each traffic light steel pole is inspected for flatness, wind resistance, coating adhesion and dimensional accuracy after completion. Defective products are rejected and qualified traffic lamp poles are packaged neatly and shipped.
II. Benefits of Standardized Processes
1. Excellent corrosion and rust resistance, long service life
Hot-dip galvanizing + electrostatic powder coating dual anti-corrosion process, double-layer protection, wind, rain, acid and alkali corrosion, can be used outdoors for 15-20 years, without frequent replacement and maintenance, suitable for various harsh outdoor environments.
2. Resistance to wind and pressure, stable structure
The one-piece molding + full welding process makes the traffic lamp poles have strong overall toughness and high load-bearing capacity, which can resist deformation and breakage, and can withstand strong winds, rain and snow pressure, meeting the safety standards of municipal road engineering.
3. Beautiful and suitable for urban construction
The grinding and uniform powder coating process ensures a smooth and flat surface with uniform color, which can prevent fading and paint peeling. Neat and elegant design meets the requirements of cleanliness and aesthetics for smart city roads.
Qixiang specializes in producing road traffic poles of various specifications, using carefully selected high-quality national standard steel and employing CNC cutting, integrated bending, and full welding and grinding processes. The entire traffic lamp pole features double anti-corrosion treatment with hot-dip galvanizing and powder coating, making it wind-resistant, pressure-resistant, rust-proof, corrosion-resistant, and resistant to fading and deformation. Strictly produced according to municipal standards, the workmanship is meticulous, dimensions are standardized, customization is supported, and the high quality ensures long-term outdoor use, making it a reliable choice for various municipal engineering procurement projects.
