Product  Brief  Introduction

 

Hot-Dipped Corrugated Steel  Roofing 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 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 are the sectors in which galvanized steel strips can be used?
Steel sheet galvanized steel strip is a kind of narrow and long steel plate produced by various 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 called steel belt, is slightly different in length 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.
Q:What does galvanized steel strip A6 mean?
The difference between the two is that one zinc plating, one without plating, the other with zinc, is more resistant to oxidation and corrosion
Q:What are the raw materials for making strip steel?
The cold rolled strip used for packing is made of plain carbon steel, low alloy structural steel, fine carbon steel and alloy structural steel. It is specially used for packing and strapping.
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:What is the difference between steel strip and strip steel?
The difference is: the strip, that is used for processing into steel belt materials, iron and steel enterprise is produced by hot rolling cold rolling plate, a large volume of.
Q:What about the strip scraping in the annealing furnace?
When the plate shape is not good, the strip tension is too low or the nozzle is too close to the strip, it may cause the contact between the nozzle and the strip,
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:What's the cutting edge of cold rolling strip?
Cold rolled materials are generally cut edges. The hot rolled material is partly rough. Cutting edges and burrs can be viewed straight. The two sides of a strip of steel, similar to those of waves. The two sides of the trimming are straight.
Q:What does "strip 50" mean?
Medium carbon high strength carbon steel, after quenching with high strength and hardness of the steel cutting medium, cold plastic deformation, poor welding, heat treatment when no temper brittleness, but the hardenability is low, the critical diameter of water is 13*30mm, and when the water quenching cracking tendency. This steel is usually used after normalizing or quenching, tempering, or high frequency surface hardening.
