Rectangular tube is a hollow square cross-section light thin-walled steel tube, also known as steel cold-bent profile. It is a square cross-section steel made of Q235 hot-rolled or cold-rolled strip or coil as the base material, which is formed by cold bending and then high-frequency welding. It is mainly used in construction, machinery manufacturing, steel construction projects, shipbuilding, etc.

Spiral welded pipe is made by rolling low-carbon structural steel or low-alloy structural steel strip into a tube blank at a certain spiral angle, and then welding the tube seams together. It can be used to produce large-diameter steel pipes with narrow strip steel. It is mainly used for oil and natural gas pipelines.

Carbon steel welded pipe is a common metal welding products, is the use of hot and cold rolled sheet coil or steel strip after forming and welding into a pipe a steel pipe. According to different forming methods and welding methods, carbon steel welded pipe can be divided into straight seam welded pipe and spiral welded pipe two types. Usually used to transport gas, liquid, solid powder or bulk materials.

Copper is one of the earliest metals discovered by humans, and it is also one of the best pure metals, slightly hard, extremely tough, and resistant to wear. It's also very malleable. Good thermal and electrical conductivity. Copper and some of its alloys have good corrosion resistance, copper and some of its alloys have good corrosion resistance and are very stable in dry air.
