Aluminum foil is a thin, flexible sheet of aluminum metal, typically less than 0.2mm thick. It is known for its lightweight nature, excellent barrier properties, and high thermal conductivity. Aluminum foil is widely used in packaging, insulation, and cooking due to its ability to resist moisture, light, and heat. Its versatility, ease of handling, and recyclability make it a preferred material for numerous applications.
DX51D+Z/DC51D+Z (CR) Galvanized Corrugated Plate is a cold-rolled hot-dip galvanized product with excellent corrosion resistance and structural rigidity, ideal for roofing, wall cladding and temporary buildings, complying with EN/GB standards.
The biggest advantage of galvanized steel plate is excellent corrosion resistance, painting, decoration and good formability. With the development of industry, hot dip galvanizing products have been used in many fields. The advantage of hot dip galvanizing is that the anti-corrosion life is long and it has been a popular anti-corrosion treatment method to adapt to the environment widely. It is widely used in power tower, communication tower, railway, highway protection, road light pole, Marine component, building steel structure component, auxiliary facilities of substation, light industry and so on.
Color coated steel coil (PPGI)is a product made of cold-rolled steel coil and (aluminum) galvanized steel coil after surface chemical treatment, coating (roll coating) or composite organic film (PVC film, etc.),and then baking and curing. This product is produced by the manufacturer in coils on the continuous production line, so it is also called prepainted steel coil. It not only has the properties of high mechanical strength and easy forming of steel materials, but also has good decoration and corrosion resistance of coating materials.
DC53D+Z Color Coated Corrugated Board, with a high-formability galvanized substrate and weather-resistant topcoat, offers superior deep-drawing performance and double corrosion protection, ideal for curved roofing and custom-shaped architectural cladding.
DX51D+Z Galvanized Coil—with 270-500MPa tensile strength and excellent weldability—is a budget-friendly choice for both construction and light industry, compliant with multiple international standards.
8620 steel bar is made of a kind of low alloy steel mainly composed of iron, carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel and other elements. It has good hardenability and weldability, and can obtain excellent mechanical properties through heat treatment.
SPHC, SPHD and SPHE pickled & oily hot rolled carbon steel coils are professional deep-drawing base materials graded by JIS G3131. With progressively optimized ductility and ultra-low impurity control, these stamping-grade coils deliver exceptional forming performance from general shallow stamping to complex deep drawing. Widely used for home appliance shells and automotive structural parts, they serve as the core base stock for cold rolling and precision metal stamping factories.
Carbon steel plates have many uses and a large amount. They are mainly used in railways, bridges, and various construction projects to manufacture various metal components that bear static loads, and unimportant mechanical parts and general welded parts that do not require heat treatment.
Carbon steel pipe in the performance of the outstanding performance is high yield strength and stress corrosion resistance, has good weldability, welding cold crack and hot crack are less sensitive.
Carbon steel tubes are divided into hot rolled and cold rolled (drawn) steel tubes.
Hot rolled carbon steel tubes are divided into general steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel tubes, petroleum cracking tubes, geological tubes and other steel tubes.
Cold rolled (dial) carbon steel pipe generally are divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, other steel pipe, also includes carbon thin wall steel pipe, alloy thin wall steel pipe, stainless steel pipe, special-shaped steel pipe.
A53 American standard seamless steel pipe is made of high-quality steel billets through hot rolling, cold drawing and other processes. The chemical composition and mechanical properties of this steel pipe comply with the requirements of American standard ASTM A53/A53M.
ASTM A333 is the standard specification for seamless and welded carbon and alloy steel pipe for low temperature applications or other applications requiring notch toughness. This standard covers several grades of ferritic steel: Grade 3, Grade 4, Grade 6, Grade 7, Grade 8, Grade 9, Grade 10 and Grade 11.
