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.

Hot Rolled Round steel pipes are the ones which are mostly for structural purpose, construction industries.Comply to the standard including ASTM A53, BS1387, ASTM A500, EN10219, EN10210, AS/NZS 1163, JIS G3444 etc.

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.

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,

Special shaped pipes generally have large moment of inertia and section modulus, and have large bending and torsion resistance, which can greatly reduce the structural weight and save steel.
