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 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: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:Hot rolled strip, the theory of the thinnest, how thin rolling, why not rolling too thin, is the material or the reasons for plate shape?
Tangshan Iron and steel production line design capacity of 0.8mm, the thin can be rolled to 1.8 or limited production, steel level, the purity of molten steel are related, and also there is a certain relationship between the plate width.
Q:Why is strip heat cheap?
Coil is 800mm in width, material better than the strip, because hot rolled production to refining furnace.
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:Is the strip steel strip?
Including strip steel, generally speaking, the strip refers to the plate and strip of the general term, but the plate in the middle part of the plate and the delivery of sheet metal is cut from the strip.
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 difference between steel strip and strip steel?
In some less strict people, it is easy to confuse these two names, but also on the Internet with the same strip of steel.
Q:What's the cutting edge of cold rolling strip?
Do you mean the cutting edge is the indication of the steel roll out of the factory? When the steel factory leaves the factory, the steel coil will have the burr and the cutting edge two kinds, the rough edge is the steel strip two, the edge is not neat. The trimming is the two sides of the steel band, and the width of the strip is certain when it is trimmed.
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.
