It is an economical, general purpose steel grade offering moderate strength and toughness. As a standard grade, 1008 steel is used in many common, low-stress applications. Weldability (spot, projection, butt, and fusion) and brazeability are excellent.

A572 steel has four different grades: 42, 50, 60 and 65. Each of these grades differ in their mechanical properties and chemical composition.

Hot-dip galvanizing is one of the effective means to delay the environmental corrosion of iron and steel materials, it is the surface of the cleaned, activated iron and steel products immersed in molten zinc, through the reaction and diffusion between iron and zinc, in the iron and steel products surface plating good adhesion of zinc alloy

Galvanized pipe is a metal pipe whose surface is covered with a layer of zinc, which has good anti-corrosion properties and durability. Hot-dip galvanized pipe is a steel pipe that is heated at high temperature and then immersed in a galvanizing solution to form a thick zinc layer, which has high anti-corrosion performance and durability. Electroplated galvanized pipe uses steel pipe as the cathode and deposits a thin zinc layer on the surface through electrolysis, which has good anti-corrosion performance and decorative properties. Galvanized pipes are widely used in water supply, drainage, heating and other piping systems in the construction field and are widely used in sewage, rainwater, tap water and other pipeline systems in the municipal field.

PPGL is pre-painted galvanized iron, also known as pre-coated steel, coil-coated steel, color-coated steel, etc., usually with hot-dip galvanized steel substrate. The term is an extension of GI, which is the traditional abbreviation for Galvanized Iron.Galvanizing protects the base steel by providing cathodic and barrier protection. The paint coating acts as a barrier protection to the hot-dip galvanized coating, significantly reducing the corrosion rate of zinc.

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.
