China Galvanized Steel Tube Supplier Guide
Galvanized steel tubes are strong and long-lasting pipes. They are used in construction, water systems, scaffolding, fences, and factories. These tubes do not rust easily. Choosing the right galvanized steel tube suppliers, especially China galvanized steel tube manufacturers, helps you get good quality pipes and on-time delivery.
This guide will explain the types, sizes, uses, and how to choose the right galvanized steel tubes.
What Is a Galvanized Steel Tube?
A galvanized steel tube is made of steel. It can be welded steel or seamless. A zinc layer covers the pipe to stop rust. Hot dip galvanized steel tubes are dipped in melted zinc. This makes the zinc layer thicker and stronger.
Benefits of galvanized steel tubes:
Last a long time (20–50 years)
Protects well against rust
Strong and hard
Needs little maintenance
Can be used inside or outside
The zinc layer makes the tubes good for water pipes, fences, scaffolding, and building supports.
Common Sizes of Galvanized Steel Tubes
China galvanized steel tube suppliers make many sizes. Tubes are measured by nominal pipe size (NPS), outer diameter, wall thickness, and length. Standard lengths are 6 meters or 12 meters.
NPS (Inch) | OD (mm) | Wall Thickness (mm) | Weight (kg/m) |
1/2" | 21.3 | 2.6-3.2 | 1.22-1.45 |
3/4" | 26.9 | 2.6-3.2 | 1.50-1.85 |
1" | 33.7 | 3.2-3.8 | 2.40-2.85 |
1-1/2" | 48.3 | 3.2-3.8 | 3.60-4.30 |
2" | 60.3 | 3.6-4.5 | 5.45-6.70 |
3" | 88.9 | 3.8-4.8 | 8.70-11.30 |
4" | 114.3 | 4.0-5.4 | 11.8-16.10 |
Custom sizes and thicknesses are available from China galvanized steel tube suppliers.
Standards of Galvanized Steel Tubes
Good China galvanized steel tube products follow world standards:
ASTM A53 / A795
BS 1387
EN 10255
ISO 65
The zinc layer usually is 40g/m² to 600g/m². Thicker zinc layer means better protection, especially outdoors.
Applications of Galvanized Steel Tubes
Size Range | Uses |
1/2" – 1" | Water pipes, handrails, furniture, garden frames |
1-1/4" – 2" | Scaffolding, fences, greenhouses, small structures |
2" – 3" | Supports, fire pipelines, industrial use |
4" – 6"+ | Big drainage, factories, heavy construction |
China galvanized steel tube products are popular in Africa, Southeast Asia, and the Middle East because they last long and are strong.
