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.

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.

Function and Application of Steel ShapesSection steel is a special type of steel that is processed and cold bent into specific cross-sectional shapes, such as H-shaped steel, I-shaped steel, angle steel, etc. Steel profiles have high strength, stiffness, and stability, and are widely used in fields such as construction, bridges, and mechanical manufacturing. It can provide support, support, and connection functions, as well as withstand and disperse gravity and structural loads.

Color coated steel coil is a type of steel coil product that has undergone special coating treatment and can have various colors and surface effects. It is widely used in fields such as construction, household appliances, and transportation.

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 use of colored steel platesColor coated steel plate is a type of steel plate with a surface coated with color coating, which has a wide range of applications.

Aluminum zinc coated coils are a common metal coating product mainly used for corrosion prevention and enhancing material weather resistance.

In the field of architecture, aluminum zinc coated coils are commonly used for building roofs, walls, and exterior wall insulation panels, as a material with good weather resistance. It can provide good corrosion resistance, extend the service life of buildings, and also have good UV resistance and heat resistance. In the field of power and communication: Aluminum zinc coated coils are also widely used in facilities such as power towers, transmission lines, and communication towers.

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.

Color steel coil is widely used, can be used as a wall, can also be used as a roof, the application field is different, its thickness choice is not the same.
