Product Brief Introduction

 

 Premium Colored Corrugated Roofing Steel Sheet

 

 --- Corrosion resistance: Pre-coated steel offers excellent corrosion resistance achived through continuous hot DIP galvanization and corrosion resistant primer/polyester coating. Protection is achieved when zinc and steel are together in the presence of moisture; The zinc protects the steel by galvanic action

Q:What are the sectors in which galvanized steel strips can be used?
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. Strip steel is widely used in the production of welded steel pipe, made of cold formed steel billet, manufacturing bicycle frame, rim, clamp, gasket, spring, saw blades, hardware and blades. The use of hot galvanized strip is naturally associated with the application of galvanized strip in construction, light industry, automobile, agriculture, animal husbandry, fishery and business. Now, with the improvement of various industries, electronics and other manufacturing processes, the application of materials is also more and more widespread.
Q:What does galvanized steel strip A6 mean?
The chemical and chemical reactions between the substrate and the molten bath of the hot galvanized steel pipe are complicated and the corrosion resistant structure is closely alloyed with zinc and iron alloy. The alloy layer is integrated with pure zinc layer and strip steel matrix. Therefore, it has strong corrosion resistance.
Q:Where is the lining board made of polyurethane lining? Please contact immediately
I don't know where to use it,Wear resistant lining board is based on the use of the environment and requirements for the product design, the earliest silo chute used in wear-resisting lining board is made of PE material fabrication and installation, but in use, PE liner wear, service life, leading to the use of units often change, very inconvenient, but also affect the normal purchase and shipment. PE material hardness is very high, food and other food raw materials in the process of loading and unloading, and PU lining plate contact parts, food will be a large number of broken, seriously affecting the quality of grain. Therefore, polyurethane wear-resistant lining board arises at the historic moment. Polyurethane wear-resistant lining board, as an elastomer product, has very high abrasion resistance and resilient cushioning performance.
Q:Why does the strip bend when it is rolled?
In the rolling process of strip tension is too large or too small will bring many adverse effects on the operation, including in the choice of a plan, must be properly chosen at each strip tension, if the improper selection of strip tension, will affect the quality of strip steel and the actual operation, when the strip coiler tension before and after the selection is too large that will cause the broken belt or rolled steel coil is heart-shaped, tension is too small will cause damage to roll off with Le roll or strip.
Q:What's the difference between hot rolled strip and cold rolled strip? What's the difference between hot rolled coil and cold rolled coil?
Hot rolled coil is above the recrystallization temperature of rolling, cold-rolled plate refers to the recrystallization temperature following rolling, popular point that is in the hot strip rolling red hot state, while cold rolled hot-rolled is under normal temperature rolling. Hot plate often said refers to the hot rolled plate, cold plate refers to the cold rolled plate, hot rolled, cold rolled and hot rolled coil is said and cold rolled coil.
Q:What's the reason for the strip after pickling?
Will it use a strong acid wash, and the temperature is too high to destroy the ductility of steel?.
Q:What is cold rolled strip and hot rolled strip? Why is it called strip steel?
Hot rolled steel strip in the processing of molding, the raw material is in high temperature, that is, after heating rolling forming, so called hot rolled steel strip, in contrast, have better toughness, soft and easy bending deformation.
Q:Steel industry, strip 195, where can strip be used?
195, material, steel pipe and profiles, I do not know which you ask. Roughly the same as Q235. The curve is different when it is round. There are 195 materials drilling is not convenient, carbon content is too high, easy to hurt the drill bit.
Q:Pickling process of cold rolled strip
The continuous pickling line is divided into 3 sections according to the nature of the work:Inlet section: feeding, unwinding, strip surface, iron oxide crushing, straightening, shearing, shearing and welding;Pickling section: acid washing, hot and cold washing and drying;Exit section: shearing, oiling, and final take-up (take-up).
Q:Can cold rolled strip be plated with white zinc?
Sure。 Electroplating cold rolled plate surface is gray rust, after plating the cold rolling plate smoothness is higher than that of hot rolled plate.
