gb standard square pipe

A square pipe of GB standards is a popular choice among many industries, with its capability to resist moderate external pressures and its attractive weldability and exterior finish. From construction work, to machinery assembly, through steel structure crafting, shipbuilding, solar panel installation or food-processing, the GB standard square pipe offers reliable stability to support a wide range of projects.

Square pipes serve as an integral structural base in modern construction and machine fabrication. In constructing significant load-bearing columns, pillar frames, and steel supports in commercial buildings, square pipes take up the slack. Machinery manufacturers also capitalize on their sturdy design by using them to make parts of robust machines. Even seafaring vessels benefit from these sturdy pipes when used as durable hulls that steer them through the waves. Additionally, solar power projects utilize the support of these reliable pipes when mounting solar panels, while food processing companies rely on them to construct equipment necessary for handling food products.

In the People’s Republic of China, the GB Standard Square Pipe has been officially measured and standardized by the State Bureau of Technical Supervision. It comes in a range of sizes from 20*20mm to 400*400mm, with a wall thickness varying between 1mm to 28mm. All measurements are specified in millimeters.

The rectangular pipes that follow the GB standard are typically crafted from Q195, Q215, Q235, Q345, ST37, ST52, 10#, 20#, 45#, and other materials. TheseGB-compliant tubes usually come in lengths of 6m, 9m and 12m while specialty sizes can also be sourced based on the buyer’s needs.

The surface of GB standard square pipes can come in two distinct forms – black and galvanized. The black surface is lightly polished and formed through hot-rolling, pickling, cold-rolling, and annealing, creating a pristine and rust-free finish. On the other hand, the galvanized finish is attained with hot-dip galvanizing to produce a uniform, highly durable product with great adhesion strength.

The GB Standard Square Pipe is employed in many industries, from the construction sector to food processing, for its effectiveness and stability. Able to support moderate external tensions, it’s a convenient option for machinery manufacturers as well as for solar panel technicians. What’s more, its simple welding process and impeccable finish make it an invaluable material for many projects.
