Hot Dipped Galvanized Steel Coil/Hot Dipped Galvanized Steel Strips Coil/Zinc Coated Steel Coil Description:

Galvanized steel coil are widely used in the construction industry, as raw material for the production of corrugated panels, fencing products, drywall panel profiles, ventilation systems etc. Recommended for both outside and inside usage, galvanized steel has a high resistance to corrosion in different environments, due to a protective layer of zinc of 100 – 180 grams per square metre.

Main Features of Hot Dipped Galvanized Steel Coil/Hot Dipped Galvanized Steel Strips Coil/Zinc Coated Steel Coil:

Hot-dip galvanized steel coils are produced by immersing steel in a zinc bath. An appropriate galvanizing process requires a pretreatment process during which the steel passes through different baths which prepare the surface for zinc coating. In this stage, chemicals are used to clean the surface of the steel. After the chemical treatment, the steel coils pass through a bath of melted zinc at temperatures around 460 ° C. The resulting uniform coating is finished through a process of skin-passing to provide smooth and shiny appearance of the finished product. To store for a longer period, the hot-dip galvanized coils can be delivered with a final oil coating, according to the customer’s demand.

Q:What is the hardness of cold rolled steel strip?
The thickness of cold rolled strip and sheet is 0.1 ~ 3mm, and the width is from 100 to 2000mm. The products are made of hot rolled strip or steel plate and rolled in cold rolling mill at room temperature. Cold rolled strip and sheet have the advantages of smooth surface, smooth surface, high dimensional accuracy and good mechanical properties. Most of the products are formed into rolls, and a large part of them are processed into coated steel plates. The roll cold rolled sheet has the advantages of high production efficiency, convenient operation and favorable follow-up processing. Therefore, widely used, it has gradually replaced the same thickness of hot rolled sheet. Only a small number of cold rolled alloy sheets for special purposes are rolled by single plate. The production of cold rolled strip and sheet steel accounts for about 30% of the total output of steel in developed countries. In addition to ordinary carbon steel, there are silicon steel, stainless steel and alloy structural steel, etc..
Q:What is the cause of the deviation of the strip in the rolling process? How to deal with it?
Because of the sudden decrease or disappearance of the tension of coiler during the rolling process, the strip is running off and breaking.
Q:Hot rolled strip and hot rolled strip are also sealing plates? What's their function?
First of all, there are some hot rolled strip, the main role is to prevent roll cooling water flow to the workpiece, affecting the crown of the strip and shape control.
Q:What are the advantages of cold rolling and cold rolling strip steel?
What to do with cold rolling is better than that of hot rolling, which is the main one because cold rolling is processed by hot rollingCold: hot rolled steel coil as raw material by pickling descaling after cold rolling, the finished rolling hard volumes, due to continuous deformation caused by cold hardening the volume rolling hard strength, hardness, toughness index rise decline, so the stamping performance will deteriorate, only for a simple deformation of parts.Cold rolled steel strip and sheet thickness is generally 0.1 ~ 3mm, width 100 ~ 2000mm in hot strip steel or timber as raw material, under normal temperature after cold rolling, cold rolled steel strip and sheet has the advantages of smooth surface, smooth, high precision and good mechanical properties.
Q:What gas does the shear of the strip weld require for the welder?
Shear machine is used to end cutting neat strip, shearing machine to use with about two sets of cutting edge of herringbone shear is appropriate. In order to reduce the contact area of the welding machine, all the shearing machine and the working line of the machine are arranged at an angle.
Q:Where is the good quality of galvanized steel strip?
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:Reasons for black side of hot strip galvanizing
The content of zinc chloride in plating bath is too low, which leads to some parts can not be plated and lead to local blackening.
Q:Steel industry, strip 195, where can strip be used?
Q195 carbon content is low, the strength is not high, plasticity, toughness, processing and welding performance is better.
Q:What does "strip 50" mean?
It is a kind of narrow and long steel plate produced by all kinds of steel rolling mills in order 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.
Q:1 can thick galvanized steel square pipe burn welding?
Welding can only use 2.5 of the electrode, the current transferred to 80A, slowly welding, yes, I have also welded. If the line is conditional, do better with sub fluorine welding or oxygen welding.
