Carbon rod is non-metallic product, it has high temperature resistance, good electrical conductivity, not easy to break properties, suitable for cutting metal into the required shape. Because of the high temperature of the carbon rod, it is easy to conduct electricity and has good chemical stability. It has been widely used in national defense, machinery, metallurgy, chemical industry, casting, non-ferrous alloy, lightening and other fields, especially black carbon rod, also used in ceramics, semiconductors, medicine, environmental protection, laboratory analysis and other fields, has become the most widely used non-metallic materials.

Angle steel,commonly known as angle iron ,is a carbon structural steel used in construction. It is a long strip of steel with two sides perpendicular to each other. It is a profile steel with simple section . Angle steel is divided into equal Angle steel and unequal Angle steel. The raw billet for the production of steel angles is low carbon square billet, and the finished Angle steel is devided into hot rolled, normalized or hot rolled state. Angle steel can make up different stress components according to the different needs of the structure, as the connection between components. Widely used in a variety of building structures and engineering structures, such as beams, Bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouses.

Steel coil, also known as coil steel. The steel is formed into rolls by hot pressing and cold pressing. In order to facilitate storage and transportation, and to facilitate various processing (such as processing into steel plates, steel strips, etc.).

The raw material of carbon steel is easy to find, so it is usually low in production cost. It has a robust construction, high ductility, easy fabricating, good abrasion resistance, and great versatility. It is in a wide selection of thicknesses, sizes, grades, and types to choose from. Being a cost-effective alternative to GI, GL, and SS steel.

It is a long strip of steel with an I-shaped cross section. I-beams are divided into ordinary I-beams and light I-beams. It is a section steel with an I-shaped cross-section. Whether the I-shaped steel is ordinary or light, because the cross-sectional size is relatively high and narrow, the moment of inertia of the two main axes of the cross-section is quite different, so it can only be directly used for members that are bent in the plane of its web or formed into a lattice-type force-bearing member. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which limits its application range. I-beams are widely used in buildings or other metal structures. The selection of I-beams in structural design should be based on its mechanical properties, chemical properties, weldability, structural dimensions, etc. to select reasonable I-beams for use.

Seamless steel pipe is a round, square and rectangular steel with a hollow section and no joints around it. Seamless steel pipes are made of steel ingots or solid tube blanks through perforation to make capillaries, which are then hot-rolled, cold-rolled or cold-drawn. The seamless steel pipe has a hollow section and is widely used as a pipeline for conveying fluid. Compared with solid steel such as round steel, the steel pipe has a lighter weight when the bending and torsional strength is the same. It is an economical section steel and is widely used in the manufacture of structures. parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycle frames, and steel scaffolding used in construction.

Black iron carbon square steel pipe and tube

Welded steel pipe, also known as welded pipe, is made of steel plate or strip after crimping forming welded steel pipe. Welded steel pipe production process is simple, high production efficiency, variety of specifications, less investment in equipment, but the general strength is lower than seamless steel pipe.

Channel steel is a long stripe of steel with a fluted section, construction and mechanical use of carbon structural steel, and is a profile steel with complex section. Its section shape is groove shape. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing., It is often used together with I steel. Channel steel is divided into ordinary u-steel and light Channel steel. The specification of hot rolled ordinary Channel steel is 5-40#. The specification of hot rolled flexible Channel steel is 6.5-30# after agreement between the purchaser and the supplier.
Channel steel can be divided into four kinds according to the shape: cold bending equilateral u-steel, cold bending unequal side Channel steel, cold bending inner edge coil Channel steel, and cold bending outer edge coil u-steel.
