Angle steel, commonly known as angle iron, is a long strip of steel that is perpendicular to each other and forms an angle. It's the same type of steel, just called differently. It is a section steel specially used to make shelves. It has various shapes and many long holes for people to string screws. It is mainly used for personal shelves in shopping malls and factories.
Channel steel is a carbon structural steel for manufacturing and machinery. It is a section steel with a complex section, and its cross-sectional shape is groove-shaped. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing. In use, it is required to have good welding, riveting performance and comprehensive mechanical performance.The raw material billet for producing channel steel is carbon-structured steel or low-alloy steel billet with a carbon content not exceeding 0.25%.
Roofing sheet is a profiled plate processed by a series of processes such as rolling and cold bending of color steel plates into various wave shapes.It not only has the excellent decorative performance of traditional clay tiles, but also has the excellent performance of modern metal tiles. It is light, strong and durable. It is the current mainstream roofing material.
And cold-rolled coil (annealed state): it is obtained by bell-type annealing before the chilled coil is rolled. After annealing, its work hardening phenomenon, that is, the decrease in yield strength is close to that before cold rolling.Definition of cold rolled coilCold-rolled coils are made of hot-rolled coils, which are rolled at room temperature below the recrystallization temperature, including plates and coils.
Galvanized steel pipes are divided into cold galvanized steel pipes and hot galvanized steel pipes. Cold galvanized steel pipes have been banned, and the latter has been advocated by the state for temporary use. In the 1960s and 1970s, developed countries began to develop new types of pipes, and have banned galvanized pipes. China's Ministry of Construction and other four ministries and commissions also issued a document explicitly banning galvanized pipes as water supply pipes from 2000.
Aluminum tube refers to a metal tubular material that is hollow along its entire longitudinal length through extrusion processing of pure aluminum or aluminum alloy. There can be one or more closed through holes, the wall thickness and cross-section are uniform, and they are delivered in straight lines or in rolls. Widely used in automobiles, ships, aviation, electrical appliances, agriculture, electromechanical, home furnishing and other industries.
Aluminum profiles are an vital fabric for current enterprise and life, exerting impact with special overall performance and vast application.Product characteristics1.Lightweight and excessive strength: The density of aluminum is about 2.7g/cm³, which is 1/3 of steel. It is effortless to lift and install.
Corrugated board is also called profiled plate. It adopts color coated steel plate, galvanized sheet and other metal sheets to be rolled and cold-bent into various corrugated profiled plates. It is suitable for industrial and civil buildings, warehouses, special buildings, large-span Roof, wall and interior and exterior wall decoration of steel structure houses.
As an vital metallic material, carbon metal performs an vital position in many fields with its incredible performance.In the development industry, carbon metal is one of the key substances for constructing secure structures.
Recently, the color roll market has shown a booming trend, and its demand is growing in many areas, which is inseparable from its continuous improvement of production technology.Substrate preparation: The substrate of the color coated coil is usually cold-rolled strip steel or hot-rolled strip steel, and some will also use hot galvanized sheet, hot aluminum plated zinc plate, electrogalvanized sheet, etc.
