Product  Brief  Introduction

 

Hot-Dipped Corrugated Metal 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's the difference between cold rolled strip and cold rolled strip?
Cold roll is usually called hard roll, 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.
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:What is cold rolled strip and hot rolled strip? Why is it called strip steel?
Strip is because rolled steel like tape, Gu called strip steel.Cold rolled strip is a strip of steel that is rolled directly without cold.Hot rolled strip is rolled or not cooled billet rolled strip.
Q:What is the difference between cold plate and strip steel?
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. Two kinds of hot-rolled strip steel and cold rolled strip steel are processed according to processing method.
Q:1 can thick galvanized steel square pipe burn welding?
Galvanized square is a hot-rolled or cold-rolled galvanized steel or galvanized sheet for the blank shape by the cold bending process after section steel pipe welded square hollow square cross-section shape and size of the high-frequency; or the cold hollow steel well in advance of the re galvanized square by galvanizing processing of pipe.
Q:What is the difference between strip steel and silicon steel?
The sheet material rolled with silicon steel is the most widely used soft magnetic material in the field of electrical engineering. Therefore, silicon steel sheet is also called electrical steel sheet. Silicon steel sheets are widely used in motors, generators, transformers, chokes, electromagnetic devices, relays and measuring instruments. Influence of silicon content on properties of silicon steel sheet. Silicon is a good deoxidizer for steel. It combines with oxygen to convert oxygen into a stable, non carbon reduced SiO2, avoiding lattice distortion of iron by doping oxygen atoms. Silicon becomes a solid solution in alpha iron, increasing resistivity and helping to separate harmful impurities from carbon.
Q:Is there any difference between galvanized steel strip and galvanized sheet?
Broad sense means galvanized steel sheet.
Q:Specification and use of cold rolled strip
Cold rolled strip steel: widely used in construction machinery, transportation machinery, construction machinery, lifting machinery, agricultural machinery and light industry, civil and other general structural parts and stamping parts.
Q:Can the tension leveller eliminate the wave shape of strip steel completely?
We take the longest and shortest fibers in the cross section of the strip and analyze their elastic and plastic deformations under the action of tension. In addition to external force because of tension by strip in straightening process, and bending stress and bending stress is tensile stress and compressive stress of the component, and the main role is tensile stress, the main deformation so through the analysis of tensile deformation on behalf of strip.
Q:How to drill through galvanized steel strip quality piercing eye
The quality of the strip is not good, quality is not good, which made galvanized pipe, can not bend 90 degrees, depending on the quality of the strip material; general material, galvanized can be plated well.
