Uchannel（U-STEEL） is a long stripe of steel with a fluted section , construction and mechanical use of carbon structural steel, is a profile steel with complex section , its section shape is groove shape. U-Steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing., u-steel is often used together with I steel.

The angle steel is mainly used to make frame structures, such as high-voltage transmission towers, frames on both sides of the main beam of steel structure bridges, columns and booms of tower cranes on construction sites, columns and beams of workshops, etc., small places such as flower pot shaped shelves at the festival roadside, and shelves with air-conditioning and solar energy hung under windows. Angle steel is also widely used in building structures and engineering construction, such as house beams, power transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.

Stainless steel I-beam is a long steel bar with a grooved section. It can be used to form various stress components according to the different needs of the structure, and can also be used as a connector between components. It is widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, hoisting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves. Stainless steel I-beam is a carbon structural steel used for construction. It is a simple section steel, mainly used for metal components and plant frames. Good weldability, plastic deformation performance and mechanical strength are required in use. The raw steel billet of stainless steel I-beam is low carbon square steel billet, and the finished stainless steel I-beam is delivered in hot rolling forming, normalizing or hot rolling state.

Aluminum plate is the thickness of more than 0.2mm to less than 500mm, the width of more than 200mm, the length of less than 16m aluminum material is called aluminum sheet or aluminum sheet, below 0.2mm for aluminum,200mm width within the bar or bar.

It has good mechanical properties, good plasticity in hot state, good plasticity in cold state, good machinability, easy fiber welding and welding, corrosion resistance, but easy to produce corrosion rupture, in addition, it is a common copper variety widely used.
