1.Structure of Hot-Dip Galvanized Steel Sheet Description

Hot-dip galvanized steel coils are available with a pure zinc coating through the hot-dip galvanizing process. It offers the economy, strength and formability of steel combined with the corrosion resistance of zinc. The hot-dip process is the process by which steel gets coated in layers of zinc to protect against rust. It is especially useful for countless outdoor and industrial applications. Production of cold formed corrugated sheets and profiles for roofing, cladding, decking, tiles, sandwich walls, rainwater protective systems, air conditioning duct as well as electrical appliances and engineering.tungsten, carbon and so on. Basically, steel is an iron-carbon alloy that does not undergo eutectic reaction. In contrast,cast iron does undergo eutectic reaction, juveniles and non-breeding males have predominantly grey-brown plumage, but breeding males adopt brilliant colours, with an iridescent silvery-blue crown and upper back, red-brown shoulders, a black throat, grey-brown wings and pale underparts. Though the red-winged fairywren is locally common, there is evidence of a decline in numbers. Primarily insectivorous, it forages and lives in the shelter of scrubby vegetation in China.

5.FAQ of Hot-Dip Galvanized Steel Sheet 

We have organized several common questions for our clientsmay help you sincerely: 

1.How about your company

A world class manufacturer & supplier of castings forging in carbon steel and alloy steelis one of the large-scale professional investment casting production bases in China,consisting of both casting foundry forging and machining factory. Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirements.

2.How to guarantee the quality of the products

We have established the international advanced quality management systemevery link from raw material to final product we have strict quality testWe resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

3. How long can we receive the product after purchase?

Q:Is the coil strip? Is hot rolled coil and hot rolled strip the same?
Is not the same, although both are in the shape of a roll, they generally written specifications (thickness * width *C, length C said, due to the general roll up so C said, if it is a rectangular steel will have length) for example we see Ruifeng strip 2.5*315*C, 11.5*1500*C 315 and Wuhan Iron and steel coil. 1500 that the width of 315mm and 1500mm
Q:What are the raw materials for making strip steel?
Hot rolled carbon steel strip is made of ordinary carbon structural steel, mainly used for cold rolled billets, cold formed steel billets, welded steel pipe billets and bicycles and hardware products
Q:What are the differences between strip steel and round steel? Where are they mainly used?
Strip steel is a kind of narrow and long steel plate produced by various rolling mills to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Strip steel, also known as steel strip, is within 1300mm in width, and the length varies slightly according to the size of each roll. The strip is supplied in general, and has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. Same as steel plate, strip steel is divided into two kinds of ordinary strip steel and high quality strip steel according to the material used, and two kinds of hot-rolled strip steel and cold rolled strip steel according to processing method.
Q:What's the meaning of "double light" in strip cold rolling?
Strip strip coiling: general supply, with high dimensional accuracy, good surface quality, easy processing, material saving and other advantages. With the same steel plate, strip by strip material is divided into ordinary and high quality strip two; according to the processing method of cold rolled strip steel hot strip, two.
Q:What is the cause of the deviation of the strip in the rolling process? How to deal with it?
Roll, roll grinding after due to severe pressure, taper, makes the school not to the operator in the rolling process of double pendulum regulation increases taper, will cause serious side light waves caused by shape defects, cause strip deviation and broken belt.
Q:What gas does the shear of the strip weld require for the welder?
(1) inlet strip clamping mechanism.(2) shearing machine.(3) welding device.(4) export strip clamp mechanism.The inlet and outlet strip clamp mechanism is used to make the end of the strip to the middle and clamp to the welding position, including strip clamping, centering and positioning device.
Q:The degreasing time is too long, will the strip surface be oxidized?
Galvanized steel plate in spray, generally do phosphating treatment, the parameters of free acid phosphating solution should be kept low, and high temperature, acid, zinc ions reduced excessive reaction, resulting in coarse crystallization. Reference: Fa:0.8-1.5 Ta:17-28 acid ratio of about 25, the temperature can be 35-45 degrees.
Q:65 what is the hardness of the best heat treatment of manganese steel strip?
65 manganese spring steel best heat treatment hardness, mainly to have good elasticity, in the dynamic load environment conditions, there is a high yield strength. In case of heavy load, there should be high fatigue strength. Under repeated loads, it has a long service life, and has sufficient toughness and plasticity to prevent sudden brittle fracture under impact. 65 the best heat treatment hardness of manganese steel strip is HRC48, and the above comprehensive mechanical properties are the best.
Q:What is the meaning of C hot strip material, B material is how to distinguish between
Hot rolled steel plate surface is plated black brown, plating cold rolled plate surface is gray, after plating from the surface smoothness to distinguish, lengzha board smoothness is higher than that of hot rolled steel plate.
Q:What is strip steel?
A steel strip, also called a strip, is actually a thin, narrow and long steel plate, usually rolled.
