0.5mm PPGI-manufacture,factory,supplier from China

The process flow of PPGI (pre coated galvanized steel plate) coil usually includes the following steps:Raw material preparation: Purchase substrate steel coils from suppliers and perform necessary quality inspection and preparation work.Pickling: The substrate steel coil is pickled to remove surface oxides and other impurities to ensure coating adhesion.Cleaning and phosphating: Clean and phosphating the acid washed steel plate to form a phosphating film and enhance the adhesion of the coating.Primer coating: Apply the primer coating evenly on the surface of the steel plate through the coating

The substrate for color coated steel coils is usually cold-rolled sheet or hot-dip galvanized sheet, which has good strength and processing performance. On the surface of the substrate, after pre-treatment, one or more layers of coating are usually applied to enhance its corrosion resistance and decorative properties.

Galvanized coils are coils that have undergone galvanizing treatment, and their common uses and materials are as follows:Building materials: Galvanized coils are commonly used in the construction field, such as making roofs, wall panels, roof trusses, and pipes. Its anti-corrosion performance can improve the service life of buildings and has a good appearance effect. Automotive manufacturing: Galvanized coils are also widely used in the automotive manufacturing industry, such as car bodies and doors.

Angle steel quality inspection method 1. Angle steel appearance quality inspection: The surface quality of Angle steel is specified in the Angle steel use standard, and there are generally no delamination, cracks, cracks and obvious problems in the steel. In the steel use standard also specifies the allowable range of Angle steel geometric shape deviation, generally including bending degree, side width, side thickness, top Angle, weight and other requirements, and stipulates that the Angle steel must not have obvious torsion.2.

Mainly including the following aspectsAnti corrosion effect: The surface of galvanized steel plate is covered with a layer of zinc, which has good anti-corrosion performance and can effectively resist corrosion in atmospheric, water and other environments, extending the service life of the steel plate.Structural building applications: Galvanized steel plates can be used as the main material in building structures, such as for making roofs, wall panels, floors, and trusses.

 Galvanized steel wire for breeding farmsGalvanized steel wire is a carbon steel wire that is galvanized on the surface using hot dip or electroplating methods. Its performance is the same as that of straightening and tempering steel wire. It can be used as unbonded prestressed reinforcement, but at least 200-300g of zinc should be plated per square meter of area.

H-shaped carbon steel is a type of carbon steel material with a specific shape, and its cross-section presents a shape similar to the Latin letter "H". This shape design enables H-shaped carbon steel to have excellent load-bearing performance and stability in structural engineering. H-type carbon steel is commonly used to manufacture components that need to withstand large loads in bridges, building structures, mechanical equipment, and other heavy engineering projects.Carbon steel is an alloy steel containing carbon elements, which has good strength and wear resistance.

Angle steel is a common metal material with an L-shaped cross-section, which consists of two perpendicular intersecting straight edges. Angle steel is usually made of carbon steel, stainless steel, or aluminum and is widely used in fields such as construction, machinery manufacturing, shipbuilding, and bridge construction. The main functions of angle steel include supporting, connecting, or reinforcing structures, commonly used to build frames, brackets, shelves, building structures, etc.

Galvanized Roofing SheetGalvanized tile sheet, also known as galvanized iron sheet, is a common building material. It is made of steel through hot-dip galvanizing process, which has the characteristics of corrosion resistance, durability, and aesthetics.Galvanized tiles are commonly used in building structures such as roofs, walls, and partitions. They can effectively prevent corrosion and oxidation, and extend their service life.

The Function and Application of U-shaped Channel SteelU-shaped channel steel is a commonly used building material with a U-shaped cross-sectional shape, also known as U-shaped steel groove or U-shaped steel groove.
