High-quality profiles, high strength, corrosion resistance, various specifications, widely used in construction, machinery and other fields, strong and durable.

Copper is a non-ferrous metal closely related to humans and is widely used in fields such as electrical, light industry, mechanical manufacturing, construction industry, national defense industry, etc. It is second only to aluminum in the consumption of non-ferrous metal materials in China. Copper is a red metal and also a green metal. Say it's green metal. Copper is also a durable metal that can be recycled multiple times without compromising its mechanical properties.

Aluminum is a silver white light metal. It has extensibility. Products are often made into rods, sheets, foils, powders, ribbons, and filaments. A layer of oxide film can be formed in humid air to prevent metal corrosion. Aluminum powder and foil can burn fiercely when heated in the air and emit a dazzling white flame. Easily soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide, and potassium hydroxide solutions, but insoluble in water. Relative density 2.70. Melting point 660 ℃. Boiling point 2327 ℃. The development of the three important industries of aviation, construction, and automotive requires the unique properties of aluminum and its alloys in material properties, which greatly facilitates the production and application of this new metal aluminum. The application is extremely extensive.

Color coated roll is a product made from hot-dip galvanized sheet, hot-dip aluminum-zinc sheet, electrogalvanized sheet, etc. as substrates, after surface pre-treatment (chemical degreasing and chemical conversion treatment), one or several layers of organic paint are applied to the surface, and then baked and cured. Color coated rolls are lightweight, aesthetically pleasing, and have good corrosion resistance. They can also be directly processed and are generally classified into gray white, navy blue, and brick red colors. They are mainly used in the advertising industry, construction industry, home appliance industry, electrical appliance industry, furniture industry, and transportation industry.

Stainless steel is often divided into martensitic steel, ferritic steel, austenitic steel, austenitic ferrite (duplex) stainless steel, and precipitation hardening stainless steel according to their structural state. Stainless steel is the abbreviation for stainless steel and acid resistant steel. Steel that is resistant to weak corrosive media such as air, steam, water, or has rust resistance is called stainless steel.

Carbon steel is steel, but not pure steel, as it is more prone to oxidation and rust due to the absence of other alloying elements. The higher the carbon steel content, the greater the hardness, and the higher the strength, which is relatively lower in plasticity. It is usually used on metal parts that require strength, hardness, and wear resistance, such as cutting tools, steel cables, piano wires, springs, and cutting tools. After processing, the parts usually need to be further processed and tempered. The higher the carbon content of steel, the higher its hardness, strength, and wear resistance after heating treatment. Carbon steel is divided into high carbon steel, medium carbon steel, and low carbon steel, each of which is further divided into two types; According to its characteristics, high carbon steel is hard and brittle, while low carbon steel is soft and ductile.
