ASTM A36 steel plate is one of the most common grades of steel used in structural applications. This mild carbon steel grade contains chemical alloys that give it properties such as machinability, ductility, and strength that are ideal for use in constructing a variety of structures.

Tinplate(SPTE) is a common name for electroplated tin steel sheets, which refers to cold-rolled low-carbon steel sheets or strips coated with commercial pure tin on both sides. Tin mainly acts to prevent corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, solderability and aesthetic appearance of tin in a material with corrosion resistance, non-toxicity, high strength and good ductility.Tin-plate packaging has a wide range of coverage in the packaging industry because of its good sealing, preservation, light-proof, ruggedness and unique metal decoration charm. Because of its strong antioxidant, diverse styles and exquisite printing, tinplate packaging container is popular with customers, and widely used in food packaging, pharmaceutical packaging, commodity packaging, instrument packaging, industrial packaging and so on.

Tinplate (also known as tinplate) refers to a cold-rolled thin steel plate coated with an extremely thin layer of metallic tin on both sides, which combines the hardness and strength of steel with the easy weldability, corrosion resistance and bright appearance of tin. The tin plate has the advantages of tasteless, non-toxic, light weight, easy processing and forming. Printing different patterns can also beautify products, so it has been widely used in the food canning industry, electronic devices, chemical paint and other industries. In the process of tin plate production, after tinning, the tin plate should be passivated in order to prevent the tin layer from oxidizing and yellowing when the tin plate is stored or the coating is baked, and to improve the performance of the tin plate such as sulfur resistance.

Carbon steel H-beam is an important steel material widely used in construction, bridges, ships, machinery and other fields. Its excellent mechanical properties and welding properties make it play a pivotal role in modern industry.

I-beam is mainly divided into ordinary I-beam, light I-beam and low alloy light I-beam. Ordinary I-beam and light I-beam flanges are thick on the web plate and thin on the outside. Ordinary I-beam, light I-beam, because the cross-sectional dimensions are relatively high, narrow, so the section of the two main sleeve moment of inertia difference is large, which makes it in the scope of application has a great limitation.

Channel steel is a long strip of steel with a groove-shaped section, which is a carbon structural steel for construction and machinery. It is a section steel with a complex section, and its section shape is groove-shaped. Channel steel is mainly used for building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.

Carbon steel angle steel is an angle steel with carbon as the main alloy element, and its carbon content is generally between 0.12% and 2.0%. Carbon steel angle steel is composed of carbon, iron, manganese, sulfur, phosphorus and other elements, among which carbon occupies a dominant position. Carbon can increase the hardness and strength of the steel, but too much carbon content can also reduce its toughness and plasticity. Carbon steel angle steel can be manufactured through various processes such as hot rolling, cold rolling, forging and casting. Due to its excellent physical properties and good processability, carbon steel angle steel is widely used in construction, engineering, manufacturing, aviation, aerospace, automobile and other fields. In the construction field, carbon steel angle steel is mainly used to build bridges and steel structures, such as highways, large industrial plants, super high-rise buildings, etc. In the mechanical field, carbon steel angle steel is often used to manufacture various mechanical parts, bearings, and gears.

‌Carbon steel flat steel‌ is an alloy steel made of carbon as the main component. It is usually made by hot rolling or cold rolling and has specific mechanical properties and chemical composition. Its cross-section is rectangular with slightly blunt edges, the width is between 12-300mm, and the thickness is between 3-60mm‌
. Carbon steel flat bars are widely used in various structures and projects, such as bridges, buildings, automobile manufacturing, industrial pipelines, etc. In the field of construction, carbon steel flat steel is often used to make steel frames in reinforced concrete structures to improve the seismic performance and wind resistance of buildings‌

HRB400 is a steel reinforcement material with high strength and good plasticity. HR stands for "hot rolling", which essentially refers to the heating and rolling process of steel bars in the production process. B represents that its yield strength is 400 megapascals (MPa) higher than that of ordinary carbon steel. HRB400 steel bars are mainly composed of alloys of carbon, sulfur, phosphorus, manganese and other
