Steel rebar is a steel material used for reinforced concrete and prestressed reinforced concrete. Its cross section is usually round, sometimes square with rounded corners. The main types of rebar include plain round bars and deformed bars. Plain round bars are actually small round bars and coils of ordinary low-carbon steel, while deformed bars have ribs on the surface, usually 2 longitudinal ribs and transverse ribs evenly distributed along the length. The shape of the transverse ribs can be spiral, herringbone or crescent.

Seamless pipes are derived from solid steel that is in sheet or bar form and is formed into a solid round shape known as “billets” which are then heated and cast over a form such as a piercing rod to create a hollow tube or shell. These kinds of pipes are known for their ability to withstand pressure more efficiently in comparison to other methods of pipe manufacturing processes, as well as being fast and cost-effective. Seamless pipes are generally used in gas lines, as well as pipes that carry liquids.

Channel 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.
Channel 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. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing., Channel steel 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.

Checkered Plate is a steel plate with raised patterns on the surface, which is anti-slip, beautiful and practical. It is widely used in construction, transportation, machinery and manufacturing, and is mainly used in places where anti-slip is required, such as stair treads, car bottoms, etc. The surface pattern design of the patterned plate not only provides good anti-slip performance, but also increases the friction of the surface, reducing the occurrence of accidents.

Hot-dip galvanized I-beams are anti-corrosion profiles formed by immersing I-beams in molten zinc at 500℃ to create a zinc alloy coating. The process involves acid washing, fluxing, and galvanizing, with a coating thickness of 30-50 microns. The metallurgically bonded zinc layer is resistant to strong acid and alkali fumes. The products are classified into hot-rolled and cold-rolled types based on the processing method, with hot-rolled being the mainstream in the market, while cold-rolled types are custom-made as needed. The material of this type of steel is mostly Q235B or Q235 carbon steel, with a compressive strength of 300-500 MPa, and the specifications cover a range of waist heights from 10# to 630#. It is mainly used in steel structures of building engineering, chemical equipment, and marine ports and docks in highly corrosive environments. It has the advantages of uniform coating, strong adhesion, and high construction efficiency. In suburban environments, its anti-rust life can reach over 50 years.

Galvanized steel coil, immersing the thin steel plate in the molten zinc bath, and adhering a layer of zinc thin on the surface.
It is mainly produced by the continuous galvanizing process, that is, the coiled steel plate is continuously immersed in the
zinc-melted plating tank to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also made by the hot-dip method, but it is heated to about 500 °C immediately after exiting the tank to form an alloy film of zinc and iron. This galvanized steel coil has good paint adhesion and weldability.

Galvanized sheet is a metal sheet made by coating the surface of carbon steel with a zinc layer. The purpose of galvanizing is to increase the corrosion resistance of carbon steel plates and extend their service life. Galvanized sheets are commonly used in construction, manufacturing, automotive manufacturing, and other areas.

Color-coated coils, the full name of color-coated steel coils, are based on hot-dip galvanized sheets, hot-dip galvalume sheets, electro-galvanized sheets, etc., and undergo surface pretreatment (such as chemical degreasing and chemical conversion treatment). A product that is coated with one or more layers of organic paint and then baked and solidified. It is named after being coated with organic coatings of various colors, referred to as color-coated rolls.
