Pre-galvanized Hollow section
Pre-galvanized hollow section is one of the main structural steel materials in the profile and light house of the civilization construction. It will be manufactured by ERW & HFW. The main usage: chemical transfer, green house, fence steel pole etc, the zinc coating thickness is 40g/m2-200g/m2, The main advantage is the welding beam is low, different sizes can be join together, if you fabricate some holes on the surface, it is very easy to do, meanwhile the position of the welding beam can be controlled during the manufacture. High Precision can be reached.

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
