Pre-galvanized round steel pipe
Pre-galvanized round steel pipe is one of the main construction materials in the normal usage. It will be manufactured by ERW & HFW. The main usage: scaffold pipe, green house, fence, fire job etc, the zinc coating thickness will be 40g/m2-200g/m2, usage validity time is around 10-25 years after the assemble. The main character is the welding beam is smooth, fabrication by cold roll material so the hardness is strong, it can be properly used in the building and furniture. Meanwhile as the precision is good some sizes are used in the equipment of the home appliance. We can also supply the bending and model fabrication of the pipe.

Production Process

1: Inspection Raw material in site (surface zinc coating and size)
2: Open Coil and Joined welding
3: Continuous ERW or HFW welding
4: Cutting
5: End and welding inspection (Painting ends)
6: Mark Packing and Trucking
