Prepainted Galvanized square pipe tube

When steel components are used to make more complex finished products, they can be galvanized before the product is assembled. This is called pre-galvanizing, or "pre-galvanizing". It may also be referred to as "in-line", "continuous" or "rolled" galvanizing.

RHS and SHS tube are a welded structural grade tubing,depending on its size and wall thickness. Either grade is ideal for all structural applications, general fabrication, manufacturing and repairs.
Square hollow section is widely used in industrial maintenance, agricultural implements, transportation equipment, truck beds, trailers, frames, etc. Its box-shape configuration allows for much greater strength and rigidity compared to angles or channels.

Product Show

Steel components (such as sheets or wires) are galvanized using an automated process before they are cut to size. This automated process will vary depending on the type of galvanized part. In general, steel components are immersed in a "galvanizing bath" of molten zinc for a short period of time. After the steel is removed from the bath, excess zinc is removed using a mechanical wiper, air knife, or steam. This leaves a relatively thin layer of galvanizing.
