Introduction to galvanised sheet materials and uses:

1、Non alloy hot dip galvanised steel strip

DC5XD series: It can be used for general purpose, and also can be used for deep drawing and nibbling. The larger the zinc content of its surface plating, the better the anti-corrosion properties; the smaller the amount of surface zinc plating, the better the processing performance.

SXXXGD Series: Can be used for structural purposes, with good processing performance and corrosion resistance.

HXXXPD+Z series: including low alloy steel, phosphorus-containing steel and hardened steel, which has superior processing performance and corrosion resistance.

2、Alloyed hot-dip galvanised steel strip

DCXXD+ZF series: Can be used for structural use, stamping and cold forming. This material of galvanised sheet has more superior welding performance and coating performance, but it is very easy to produce peeling in the process.

Galvanised sheet classification:

1, alloyed galvanised steel: hot dip method of production out of the type of steel, with good weldability and adhesion properties.

2, hot gold galvanised steel: this is a thin layer of zinc attached to the surface of the thin steel, its production process for the continuous galvanised way.

3、Electro-galvanised steel sheet: the steel sheet is galvanised by means of electricity, but the zinc plated in this way is relatively thin, and the corrosion resistance is relatively poor.

4, single-sided galvanised steel plate: only one side of the steel plate is coated with zinc, whether it is used for processing, painting or welding, adaptability is better than double-sided zinc-plated steel plate.

5, double-sided galvanised steel: single-sided galvanised steel still has some shortcomings, in order to overcome these shortcomings, but also in the other side of the steel plate coated with a thin layer of zinc, which is double-sided galvanised steel.

6, composite galvanised steel: the internal material in addition to pure steel, there are lead, aluminium and other metals composite to comply with the steel, and then plated with a layer of zinc on its surface. This kind of steel plate has more superior rustproof performance, and the painting performance is also better.

Galvanised sheet and stainless steel which is better

Galvanized sheet iron is brushed with a layer of metal zinc corrosion, cold plating and hot plating, in short, long time the surface of the zinc will fall, iron will be corroded, stainless steel does not have to corrosion chant, of course, the price is expensive, stainless steel in 200-300, only some special materials in the low temperature tempering at 200-300 degrees, but the temperature is too low, generally not a great deal of change in the galvanized sheet at high temperatures (200 degrees, 300 degrees) Under the surface layer of zinc will be slowly baked off.

There are many types of stainless steel, galvanised sheet is only in the steel plate or iron plate surface electroplated with zinc metal once. Galvanised sheet itself is a common plate, do the surface processing only. Stainless steel plate is an acid-resistant alloy plate. Depending on what you do, 200-300 degrees is not considered high temperature, relatively cheap stainless steel 430 plate price should be 2 times more expensive than the same specifications of galvanised sheet.

Stainless steel is through the addition of trace elements to achieve the purpose of changing the steel components to achieve the anti-corrosion function. Galvanised sheet is galvanised on the surface of ordinary steel plate to achieve the purpose of anti-corrosion in the form of sacrificial zinc. 200 degrees, 300 degrees on the metal are not a problem, depending on the environmental atmosphere, there will be some very small impact, but it takes a long time to have a change.
