Q235 Steel Square Bar

Steel square bar is a solid bar. Steel square bar can be divided into hot rolling and cold rolling; The length of hot rolled steel square bar is 5-250mm, and that of cold-drawn square steel is 3-100mm.

Square steel bar is also called mild steel square bar, carbon square steel bar. Mainly used in the manufacture of petroleum, chemical, gas separation and shipping container or other similar devices, such as all kinds of tower vessels, heat exchangers, storage tank and tank car, etc.

Film

1. Polyester (PE) has good adhesion, rich colors, wide range of moldability and outdoor durability, medium chemical resistance and low cost.
2. Silicon modified polyester (SMP) has good hardness, wear resistance and heat resistance, good external durability and pulverization resistance, gloss retention, general flexibility and medium cost.
3. High durability polyester (HDP), excellent color retention and ultraviolet resistance, excellent outdoor durability and pulverization resistance, good adhesion of paint film, rich colors and excellent cost performance.
4. Polyvinylidene fluoride (PVDF) has excellent color retention and ultraviolet resistance, excellent outdoor durability and pulverization resistance, excellent solvent resistance, good formability, dirt resistance, limited color and high cost.

Application

(1)Hot rolled steel square bar can be used to make components, escalators, bridges and fences.
It has good strength, and its surface is smoother than other steels. In addition, the gauge of the thickness of hot rolled steel square bar is very tight, which determines that it is very suitable for welding. The bearing weight of square steel is large, and welding is an essential processing technology in the production process of components, escalators and fences. At the same time, the surface of steel must be smooth and able to bear a certain amount of heavy objects. However, some characteristics of square steel just completely meet the requirements. This makes it a raw material for processing and manufacturing components, escalators, fences and other items.
(2)Hot rolled steel square bar can be used as a welding billet and a slab of laminated thin plates.
hot rolled steel square bar is a kind of steel with rectangular interface, which can be regarded as a part of long steel plate. This makes it possible to be processed into a steel plate with a large area.
(3)Hot rolled steel square bar can be made into hoop iron material.
hot rolled steel square bar is a long strip steel, and its thickness and width specifications are very complete. In addition, square steel has good flexibility and can be used as hoop iron material.
