Color-coated coils, the full name of color-coated steel coils, are based on hot-dip galvanized sheets, hot-dip galvalume sheets, electro-galvanized sheets, etc., and undergo surface pretreatment (such as chemical degreasing and chemical conversion treatment). A product that is coated with one or more layers of organic paint and then baked and solidified. It is named after being coated with organic coatings of various colors, referred to as color-coated rolls.

We are a wholesale supplier of PPGI steel in China with our own factory. In our factory, we have 3 color coating lines with an annual production capacity of 3.2 million tons. There are also two galvanizing lines with an annual production capacity of 10 million tons. In addition, there are different designs of rolling equipment, shear lines, etc. to meet the different needs of plain or corrugated pre-coated galvanized steel sheets. Welcome to contact us online or visit our factory on site.

Galvanized square pipe is a hollow square cross-section steel pipe with a square cross-section shape and size made from hot-rolled or cold-rolled galvanized strip steel or galvanized coil plate, which is formed by cold bending and then high-frequency welding. , or galvanized square rectangular pipes made by hot-dip galvanizing the pre-made cold-formed hollow steel pipes.

Channel steel is a long stripe of steel with a fluted section , construction and mechanical use of carbon structural steel, is a profile steel with complex section , its section shape is groove shape.
Channel steel is a long stripe of steel with a fluted  section , construction and mechanical use of carbon structural steel, is a profile steel with  complex section , its section shape is groove shape. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing., Channel steel is often used together with I steel.
Channel steel is divided into ordinary u-steel and light Channel steel. The specification of hot rolled ordinary Channel steel is 5-40#. The specification of hot rolled flexible Channel steel is 6.5-30# after  agreement between the purchaser and the supplier.

Galvalume plate, as a high-performance corrosion-resistant alloy steel plate, is made by hot-dip plating process to evenly cover the surface of the steel plate with aluminum-zinc alloy. Its main components are 55% aluminum, 43.4% zinc and 1.6% silicon. This unique alloy ratio gives the galvanized sheet excellent corrosion resistance, heat resistance and good processing performance.

Stainless steel coil is a thin steel plate supplied in coils, also called strip steel. There are imported and domestic products, divided into hot-rolled and cold-rolled. According to the needs of different users, we can also order a variety of special-shaped steel materials.In order to ensure that the yield strength, tensile strength, elongation and hardness of various stainless steel coils meet the requirements, the stainless steel coils must undergo heat treatment such as annealing, solution treatment, and aging treatment before delivery.

Stainless steel bars are widely used in industrial pipelines and mechanical structures in the fields of petroleum, chemical industry, medical treatment, food, light industry, mechanical instruments, etc. They are widely used in the manufacture of mechanical parts and engineering structures. They are also commonly used in furniture and kitchen utensils.

Steel rebar is a steel material used for reinforced concrete and prestressed reinforced concrete. Its cross section is usually round, sometimes square with rounded corners. The main types of rebar include plain round bars and deformed bars. Plain round bars are actually small round bars and coils of ordinary low-carbon steel, while deformed bars have ribs on the surface, usually 2 longitudinal ribs and transverse ribs evenly distributed along the length. The shape of the transverse ribs can be spiral, herringbone or crescent.

Stainless steel sheets have a smooth surface and high plasticity, toughness, and mechanical strength. They are resistant to corrosion from acidic and alkaline gases, solutions, and other media. It is an alloy steel that does not easily rust, but it is not absolutely rust-proof. Stainless steel sheets refer to steel sheets resistant to corrosion from weak media such as atmosphere, steam, and water, while acid-resistant steel sheets refer to steel sheets resistant to corrosion from chemically corrosive media such as acids, alkalis, and salts.
