Lead plate, refers to the plate made of metal lead rolling, the common thickness is 1-20mm, the common specification is
1000*2000M, mostly made of 1# electrolytic lead. · Lead plate, with strong corrosion resistance, acid and alkali resistance, acid environment construction, hospital radiation protection, X. Light, CT room ray protection, weight, sound insulation and many other aspects, and is a relatively cheap material.

Carbon steel rod is a rod-like material made of carbon steel with a carbon content between 0.03% and 2.0%, with high strength, good wear resistance, corrosion resistance and easy processing ‌.

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.

Carbon steel coil is a continuous steel coil made of iron-carbon alloy by hot rolling or cold rolling, with a thickness of 0.2-25 mm and a width of 600-2000 mm. It has high strength, good ductility, can be welded and punched. It is divided into low-carbon, medium-carbon, high-strength and alloy structural steel according to the carbon content, and complies with GB/T 3274, ASTM A1011 and other standards. The surface can be pickled, galvanized, and color-coated for easy subsequent processing. It is widely used in automobiles, home appliances, construction, pipelines, containers, machinery manufacturing and cold-bent parts, and is the preferred raw material for industrial mass forming and welding.

Seamless steel pipe is formed by hot rolling or cold drawing of round billet, without welds, dense structure, uniform wall thickness, high pressure bearing and good toughness. The material contains 0.1-0.6% carbon, and implements GB/T 8163, ASTM A106 and other standards, with specifications of Φ6-1020 mm×1-120 mm. It can be hot rolled, normalized, tempered or quenched and tempered, and the outer surface can be painted, galvanized, 3PE. It is used in high-pressure boilers, oil cracking, ships, machinery, hydraulic props and fluid transportation pipelines, safe and reliable, long life.

Aluminum tube is a tube made of aluminum alloy. It is light and relatively low in density. It can significantly reduce weight in various applications and facilitate transportation and installation. For example, it can reduce the load of aircraft in the aerospace field. It has good corrosion resistance and is easy to form an oxide film on the surface. It can be used stably in a variety of environments. For example, it can resist some corrosive media in chemical pipeline transportation. It has excellent thermal and electrical conductivity and can be used for heat dissipation components and conductive structural parts, such as heat pipes and electrical conductors of electronic equipment. It has high strength and can withstand a certain amount of pressure. It can be used as a structural support material, such as tent poles and scaffolding components.

Carbon steel plate is hot-rolled or cold-rolled steel with a carbon content of 0.05%-2% and iron-carbon alloy as the main material. The thickness is 0.2-200 mm and the width is 1000-3500 mm. It has high strength, good weldability and low cost. It is divided into ordinary carbon, low alloy and high-strength structural steel according to its performance. It complies with GB/T 3274, ASTM A36 and other standards. The surface can be blackened, galvanized or coated. It is used in buildings, bridges, ships, vehicles, pressure vessels, machinery manufacturing and home appliance shells. It is the largest basic material in industrial use.

Stainless steel plate is a flat product made of stainless steel as the main material, with excellent corrosion resistance, high temperature resistance and mechanical properties. It is usually composed of alloy elements such as chromium and nickel and iron-based alloys. Common grades include 304, 316, 430, etc., and are widely used in construction, chemical industry, food processing, medical equipment, home appliances, automobiles and other fields.
