Galvanized square tubing used for Intermediate bulk container steel frame.


We welded square tubing pre-galvanizde steel coil of certain thickness as 0.8mm or 0.9mm or 1.0mm into square section long square tubing then cut them incto different short lengths according later usage requirement, as varieties welding location requirement.Dry and shinning the surface with light oil to ensure long-term purpose of anti-rust as long as half year even one year.

Then for square tubing swaged the ends of long tubing or expend then other end to ensure square tubing can insert each other tightly,meanwhile for vertical lengths tubing,the whole fabricated process are cut them into short certain length and punch tubing body with certain deepth caulks,besides flatted the two ends of each piece with nipples for easy welding process.

Certainly,with long-term experience almost 20 years for square tubing, we can make finished square tubing we called steel frame joint bars not only by sqaure tubing,we can make them by round tubing,it also depends on the requirement from customer and certainly depends on quantity one time need as one time one shipment more than 20 sea feet container.
