Galvanized strip is a long and narrow strip of cold-rolled or hot-rolled steel which is coated with a layer of raw material called zinc and aluminium in varying degrees. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Complex physical and chemical reactions occur between hot-dip galvanized strip steel matrix and molten plating solution, forming a zinc-iron alloy layer with a close corrosion-resistant structure. The alloy layer is integrated with pure zinc layer and strip steel matrix. Therefore, it has strong corrosion resistance.

Steel Strip with thinner thickness, narrower width and longer length. Its width is generally between 20 mm and 200 mm. Volume supply, specifications expressed in thickness * width. According to the quality of steel, it can be divided into high quality and common strip, hot rolling and cold rolling, which are called hot rolling strip and cold rolling strip respectively. Hot-rolled common strip is 2 mm-6 mm thick, cold-rolled strip is 0.05 mm-3.60 mm. Strip steel can be made of plain carbon steel, carbon-bonded steel, spring steel, tool steel, stainless steel, etc. Widely used in manufacturing welded pipe, clamp, washer, spring blade, saw blade, blade, etc.

Steel Strip refers to the conveyor belt made of carbon steel as the traction and transport component of belt conveyor, and can also be used to tie goods. It is a narrow and long steel plate produced by various rolling enterprises in order to meet the needs of industrialized production of various metals or mechanical products in different industrial sectors. Steel strip, also known as strip steel, is less than 1300 mm in width, and its length varies slightly according to the size of each coil. Strip steel is generally supplied in coils, which has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving.

Seamless steel pipe is made of whole metal and has no seams on its surface. According to the production method, seamless pipe is divided into hot-rolled pipe, cold-rolled pipe, cold-drawn pipe, extruded pipe, pipe jacking and so on. According to the cross-section shape, seamless steel pipe can be divided into two kinds: circular and irregular. The irregular pipe has many complex shapes, such as square, ellipse, triangle, hexagonal, melon seed, star and finned pipe. The maximum diameter is 650 mm and the minimum diameter is 0.3 mm. Depending on the use, there are thick-walled and thin-walled tubes. Seamless steel pipes are mainly used for petroleum geological drilling pipes, cracking pipes for petrochemical industry, boiler pipes, bearing pipes and high-precision structural steel pipes for automobiles, tractors and aviation.

Hot rolled, or hot rolled coil, is made of slab (mainly continuous casting slab) as raw material, which is heated by roughing mill and finishing mill.The hot strip from the last finishing mill is cooled by laminar flow to set temperature, coiled into strip coil by coiler. The cooled strip coil is processed into steel plate by different finishing lines (leveling, straightening, cross cutting or longitudinal cutting, inspection, weighing, packaging and marking, etc.) according to different needs of users. Flat coil and longitudinal cut strip products.

Galvanized coil, the thin steel plate immersed in the molten zinc bath, so that its surface adheres to a layer of zinc thin steel plate. At present, continuous galvanizing process is mainly used to produce galvanized steel sheet, which is made by continuously immersing coiled steel sheet in galvanized bath and alloying galvanized steel sheet. This kind of steel plate is also made by hot dipping method, but it is heated to about 500 C immediately after the trough is out to form zinc and iron alloy film. The galvanized coil has good adhesion and weldability of the coating.

Flat steel refers to steel with a width of 12-300 mm, a thickness of 3-60 mm, a rectangular section and a slightly blunt edge. Flat steel can be used as finished steel or as blank for welded pipe and thin slab for laminated sheet rolling. Main Application: Flat steel can be used as finished material for hoop iron, tools and mechanical parts, and as building structural parts and escalators.

Welded steel pipe with hot dip or galvanized layer on the surface of galvanized steel pipe. Galvanizing can increase the corrosion resistance of steel pipe and prolong its service life. Galvanized pipes are widely used not only as pipelines for general low-pressure fluids such as water, gas and oil, but also for oil wells and pipelines in petroleum industry, especially in offshore oilfields, oil heaters, condensers and coolers for chemical coking equipment, pipes for coal distillate wash oil exchangers, and supports for Trestle pipe piles and mine tunnels. Wait a minute.

Spiral welded pipe is also a kind of welded pipe equipment. Its strength is generally higher than that of straight welded pipe. It can produce welded pipe with bigger diameter with narrower blank and welded pipe with different diameter with the same width blank. However, compared with the straight seam pipe of the same length, the length of the weld increases by 30-100%, and the production speed is lower. Therefore, most of the smaller diameter welded pipes are welded by straight seam welding, while the larger diameter welded pipes are mostly welded by spiral welding.Spiral steel pipe production process: The spiral seam steel pipe is made of strip coil plate as raw material, often extruded at high temperature, and welded by automatic double-wire double-sided submerged arc welding process.

Square pipe, as its name implies, is a kind of square pipe. Many kinds of material can form square pipe. It is used for what purpose and where. Most square pipe is made of steel pipe. After unpacking, flattening, crimping and welding, it forms round pipe. Then it is rolled into square pipe and cut into needed pipe. Length. Generally, 50 square pipes per package are in large specifications at most 10*10*0.8-1.5-500*500*10-25 in spot. Square pipes are divided into structural square pipes, decorative square pipes, construction square pipes, mechanical square pipes and so on.
