Carbon steel rectangular tube is a type of steel pipe with a square cross-section, mainly composed of elements such as carbon, manganese, silicon, phosphorus, sulfur, etc.

Welding Carbon Steel Pipe is formed from an originally flat piece of carbon steel. The piece of carbon steel is rolled and welded creating a welded seam going long ways down your piece of carbon steel tubing or piping. The weld is formed by using a high energy source to melt the local metal together.

Seamless Steel pipes with hollow sections are widely used as conduits for conveying fluids, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe has the same bending and torsional strength and is lighter in weight. It is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction.

A36 is an American standard carbon structural plate, which is subject to ASTM A36/A36M. This standard is applicable to riveting, bolting and welding structures for bridges and buildings, as well as general purpose structural steel quality carbon steel sections, plates and bars.

SPCC carbon steel plate is generally used in the production of steel structures, vehicles, ships and bridges, and has good corrosion resistance and atmospheric corrosion resistance.

Carbon steel plates have many uses and a large amount. They are mainly used in railways, bridges, and various construction projects to manufacture various metal components that bear static loads, and unimportant mechanical parts and general welded parts that do not require heat treatment.

SPCC is commonly used cold rolled carbon steel sheet and steel strip.Cold coil is made of hot rolled coil at room temperature and below the recrystallization temperature, including plate and coil, of which the sheet delivered is called steel plate, also known as box plate or plate; the long length and delivered in coil is called steel strip, also known as coil plate.

Hot rolled coil is made of continuous casting slab or first rolled slab as raw material, heated by step heating furnace, descaled by high pressure water and entered into roughing mill, roughing material is cut head, tail, and then entered into finishing mill to implement computer controlled rolling, laminar cooling (computer controlled cooling rate) and coiling machine after the final rolling, to become straight coil. Hot rolled products have high strength, good toughness, easy processing and molding and good weldability, so they are widely used in construction, machinery, boilers, pressure vessels and other manufacturing industries.
