Galvanized Round Steel Pipe

Galvanized Round Steel Pipe is made of high-quality carbon steel, which is ERW high-frequency welded and then hot-dip galvanized (HDG) or pre-galvanized, providing excellent corrosion resistance while ensuring structural strength.

Raw Material Inspection: We select high-quality steel coils and inspect their chemical composition, dimensions, and surface quality to ensure they meet production requirements.

Forming and Welding: We employ ERW high-frequency welding technology for continuous forming, resulting in strong welds and stable dimensions.

Sizing and Straightening: Online sizing and straightening improve the roundness, straightness, and dimensional accuracy of the steel pipes.

Zincing Treatment: We use pre-galvanizing or hot-dip galvanizing processes according to customer requirements to form a uniform, corrosion-resistant coating.

Finished Product Inspection: After completing dimensional, weld, coating, and appearance inspections, the finished product is packaged and shipped.

Raw Material Inspection: Each batch of steel coils undergoes chemical composition and mechanical property testing to ensure stable and reliable raw materials.

Non-destructive Testing of Welds: We use online eddy current testing equipment to inspect weld quality, ensuring welding continuity and reliability.

Coating Inspection: We use a coating thickness gauge to check the thickness and uniformity of the zinc layer, ensuring it meets standards and customer requirements.

Mechanical Performance Testing: Conducts tensile, yield, hardness, and hydrostatic tests to verify product performance meets application requirements.

Third-Party Inspection: Supports third-party inspections by SGS, BV, Intertek, etc., and can provide EN 10204 3.1 material certification (MTC).

Product Customization: Supports customization of outer diameter, wall thickness, length, steel grade, zinc coating thickness, and pipe end type.

Processing Services: Supports threading, grooving, beveling, cutting, and custom processing based on drawings to meet diverse project needs.

Packaging Customization: Supports customer logos, labels, markings, packaging methods, and OEM production.

Building Structures: Suitable for steel structures, factories, scaffolding, and building support systems, providing stable load-bearing capacity.

Water Supply, Drainage, and Fire Protection: Suitable for water supply, drainage, and fire protection networks, combining pressure resistance and corrosion resistance.

Greenhouse Agriculture: Used for greenhouse frames and agricultural facilities, exhibiting excellent durability in high-humidity environments.

Municipal Infrastructure: Widely used in the construction of fences, railings, lighting poles, and public facilities.

Machinery Manufacturing: Applicable to the processing of mechanical structures, equipment frames, and metal furniture.

International Standards: Supports production according to standards such as ASTM A53, ASTM A795, EN 10219, EN 10255, EN ISO 1461, BS 1387, and JIS G3444.

Quality Certification: ISO 9001 quality management system certification, EN 10204 3.1 material certificate (MTC), and third-party testing reports such as SGS are available.

Export Packaging: Uses steel strapping, waterproof packaging, and plastic caps for protection. Wooden crates can be provided upon request.

Container Loading: Supports 20GP, 40GP, and 40HQ container loading options, and allows for mixed loading of different sizes to improve loading efficiency and reduce transportation costs.

Export services: Supports customized shipping marks, labels, and export documents to meet project procurement and warehousing management requirements.
