Galvanized square steel pipe is a square - sectioned steel pipe that has undergone a galvanizing treatment. By plating a layer of zinc on the surface of the steel pipe, it provides excellent corrosion - resistance and is widely used in fields such as construction, machinery manufacturing, agriculture, and furniture.
Production Process
1. Base Pipe Manufacturing
Hot - rolled or cold - rolled steel strips are used to form a square - sectioned steel pipe through processes such as shaping and welding.
2. Galvanizing Treatment
Hot - dip Galvanizing: Immerse the square pipe in molten zinc liquid, so that the zinc layer adheres evenly to the surface.
Electro - galvanizing: Deposit a relatively thin layer of zinc on the surface of the square pipe through an electrolytic process.
3. Post - treatment
After galvanizing, the square pipe may go through processes such as cooling, passivation, and oiling to enhance its corrosion - resistance and surface quality.
Main Characteristics
1.Excellent Corrosion - resistance: The zinc layer effectively prevents the steel pipe from rusting and extends its service life.
2.High Strength: The square - shaped structure of the pipe is stable, with strong load - bearing capacity.
3.Aesthetic Appeal: The surface is smooth, and the zinc flower pattern is beautiful, making it suitable for occasions with high aesthetic requirements.
4.Good Workability: It is easy to cut, weld, bend, and assemble.
5.Environmental Friendliness: It can be recycled, meeting environmental protection requirements.
Specifications and Dimensions
1.Cross - sectional Shape: Square (with four equal sides) or rectangular (with unequal length and width).
2.Side length: Usually ranges from 10mm×10mm to 500mm×500mm.
3.Wall thickness: Usually ranges from 0.8mm to 20mm.
4.Length: Generally 6 meters or 12 meters, and can also be customized according to requirements.
Application Fields
1.Construction Industry: Used for steel - structure frames, scaffolding, door and window frames, etc.
2.Machinery Manufacturing: Used for structural parts and support parts of mechanical equipment.
3.Agriculture: Used for greenhouse greenhouses, breeding equipment, etc.
4.Furniture: Used for the frames of tables, chairs, shelves, and other furniture.
5.Transportation Facilities: Used for guardrails, sign poles, etc.
Differences from Ordinary Square Steel Pipe
Conclusion
Galvanized square steel pipe is a square - sectioned steel pipe that has undergone a galvanizing treatment. It has excellent corrosion - resistance, strength, and aesthetic appeal. It is widely used in fields such as construction, machinery manufacturing, agriculture, and furniture, especially suitable for occasions that require long - term anti - corrosion protection. If a lower - cost option is needed, ordinary square steel pipe can be considered, but additional anti - corrosion treatment is required.
