Square tube, as the name suggests, is a kind of square tube. Many materials can form square tube. It is used for, what to do and where to use. Most square tubes are steel tubes, mostly structural square tubes, decorative square tubes, building square tubes, etc
rectangular steel pipe

Rectangular tube is a kind of hollow long steel, also known as flat tube, flat square tube or square flat tube (as the name suggests). When the bending and torsional strength are the same, the weight is light, so it is widely used to manufacture mechanical parts and engineering structures.

steel coil/strip/plate/bar/angle/spiral ground pile

Steel coil, also known as steel coil. The steel is rolled by hot pressing and cold pressing. In order to facilitate storage and transportation, it is convenient to carry out various processing.

Strip steel is a kind of narrow and long steel plate produced by various steel rolling enterprises in order to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. Steel strip, also known as steel strip, is within 1300mm in width and slightly different in length according to the size of each roll.

Steel plate is a flat steel plate cast with molten steel and pressed after cooling.
It is flat and rectangular, which can be directly rolled or cut by wide steel strip.
Steel plates are divided according to thickness. Thin steel plates are < 4mm (the thinnest is 0.2mm), medium thick steel plates are 4 ~ 60mm, and extra thick steel plates are 60 ~ 115mm.
Steel plate is divided into hot rolling and cold rolling according to rolling.

Spiral ground pile is mainly used for solar base connection, fixed fence, fence and movable plank house. Spiral ground pile is used in soft soil. Raw materials used: welded pipe, processing technology: shaping and welding metal. Surface treatment technology of spiral ground pile: acid pickling and hot galvanizing,
