Case
Steel pipe application
Steel pipe is not only used to transport fluids and powdery solids, exchange heat, manufacture machinery parts and containers, it is also a kind of economic steel. It can reduce weight, save 20%-40% metal material, realizing the industrial mechanized construction. Making highway bridges with steel tubes can not only save steel material , simplify construction difficulty, but also greatly reduce the area of protective coating and save investment and maintenance cost.
Hot rolled steel coil and sheet application
Hot rolled products have high strength , good toughness, easy processing and good weldability. , it is widely used in construction, machinery, boiler, pressure vessel and other manufacturing industries. After annealing, it is processed into ordinary cold rolling coil .
Cold rolled steel coil and sheet application
Cold rolled steel coil is mainly used in automobile, shipbuilding, electric power, coal, light industry, household appliances,hardware and other industries, such as used in engineering machinery, transportation machinery, construction machinery, agricultural machinery and light industrial and civil industries of general structural parts and stamping parts, as well as manufacturing sewing machine, bicycles, farm machines and other accessories and hardware products.
H beam application
H beam is widely used in all kinds of civil and industrial building structures , all kinds of large-span industrial plants and modern high-rise buildings, especially in areas with frequent seismic activity and industrial plants under high temperature working conditions, large bridges with large bearings capacity, good cross-section stability and large span are required, heavy equipment , expressway, shipframe, mine support, foundation treatment and dam works, various machine components.

Welded steel pipe
Provide spiral welded steel pipe, high frequency or low frequency resistance welded pipes and other types of steel pipes. Specialized in welding stainless steel pipe,our black welded steel pipes are made of high-quality raw materials, which can be selected according to specific application scenarios and needs.Customized services are accepted.
Galvanized steel pipe
High quality galvanized steel pipe for sale. Welding galvanized steel pipe with advanced technology and raw materials. The presence of the galvanized layer effectively isolates the steel pipe from the external environment and prevents oxidation corrosion. Cutting, bending and other processing operations are simple and can meet various complex installation requirements.
PPGI
PPGI steel coil, also called ppgi galvanized steel coil. Covered with a coating made of a mixture of iron oxide and aluminum oxide on the basis of cold rolled sheet. Extremely high resistance to corrosion, wear and high temperature oxidation with good appearance. It is widely used in the manufacturing process of construction, electrical appliances, automobiles and other products.
Seamless steel pipe
Seamless steel pipes are long steel strips with hollow cross-section and no seams around it. Seamless carbon steel pipe is made of high-quality carbon steel with high yield strength and tensile strength. Refining treatment gives it good mechanical properties and welding performance. Carbon steel seamless pipe can meet various high-strength and high-durability requirements.
Angle bar
Steel angle bar is a long steel bar with two sides perpendicular to each other. It can be used to form various load-bearing components and can also be used as a connector between components. It is widely used in various building structures and engineering structures. We provide high-quality metal angle bar and stainless angle bar, which have excellent performance in practical applications.
Hot rolled steel coil
Hot rolled steel coil refers to a type of steel product that is formed by heating steel ingots or slabs to high temperatures and then rolling them into flat sheets or coils. This process results in a product with a rough surface finish and rounded edges, making it ideal for applications where precise dimensions are not critical. Hot rolled steel is known for its malleability and ductility, allowing it to be easily shaped and formed into various structural components.
Cold rolled steel sheet
Cold rolled steel sheet is a type of steel product that undergoes a process where the steel is rolled at room temperature or slightly above it. This method results in a smoother surface finish and tighter tolerances compared to hot rolled steel. Cold rolling increases the strength and hardness of the steel while maintaining its flexibility, making it ideal for applications requiring precise dimensions and a polished appearance. Cold rolled steel is commonly used in industries such as automotive, appliances, and construction
