What are the precautions for using galvanized sheets?

1. When storing, high humidity, acidic and damp environment is not conducive to its keeping. Choose a dry, clean and ventilated place in the house for storage to avoid erosion by dew or penetration of moisture. When storing, don't destroy the wrapping paper and shorten the storage time as much as possible.

2, the transportation should be covered with a good raincover, and must be padded with cushion wood and rubber pads, fixed with ropes, to try to avoid loading and unloading in the rain. Steel coils should be added under the cushion wood or support frame, stacking layers should not exceed two layers.

3, the steel plate needs to be used as soon as possible, so as not to be too long, it may occur processing performance reduction, tensile deformation and so on. Galvanized plate processing degree is too high, may destroy the zinc layer, so before use also need to confirm the degree of processing. Flat plate by the outside world under abnormal pressure, the zinc layer will be partially detached.

4, to prevent dirt and oil powder sticking to the surface so that will affect the galvanizing effect, shall not use organic solvents to wipe the surface of the steel plate, may make the surface of the zinc electroplating coating loss or peeling.

What are the differences between galvanized sheet and cold rolled sheet

1, different physical properties

Galvanized sheet corrosion resistance is good, easy to construct, while the cold rolled sheet high hardness, the surface is very smooth.

2, different materials

The main material of galvanized sheet is hot-dip galvanized steel and electro-galvanized steel, while the main material of cold rolled sheet is stamping grade cold rolled sheet.

3、Different process

Galvanized sheet through the galvanizing process on the surface of the steel plate coated with a layer of zinc, made of alloy products, and cold rolled sheet production without heating, the appearance of a better gloss.

Selection of galvanized sheet to pay attention to what

1, before buying galvanized sheet, pay attention to understand the brand, there are many brands of galvanized sheet, the choice of space is relatively large, try to choose a big brand of galvanized sheet, quality and other aspects will be more secure.

2, galvanized sheet bought back, pay attention to storage in a dry place, do not store in the wet area, which will cause some damage to the galvanized sheet.

3, buy galvanized sheet, pay attention to check the surface of the galvanized sheet, see whether there are stains, etc., if so, such galvanized sheet is best not to buy.

4, you can choose according to the galvanized sheet specifications, combined with the actual situation to buy, if you buy the wrong size of galvanized sheet, it will affect the use of galvanized sheet.

What is the use and function of galvanized

1, is usually used in the construction of houses, handicrafts production, wire mesh preparation, as well as highway guardrail kind of place.

2, galvanized wire can be divided into hot-dip galvanized and cold galvanized, hot-dip galvanized manufacturing speed, but the coating is not balanced, the lowest standard in the market is 45 microns, the highest can be more than 300 microns, and the color is very dark, need to consume a lot of zinc metal, it can be formed with the substrate metal into the layer of corrosion resistance is excellent, even in outdoor environments can be maintained unchanged for decades.

What is the difference between galvanized sheet and iron sheet?

1, the base material is different

Iron plate, also known as ordinary iron plate, is divided into hot rolled plate and cold rolled plate. The surface of hot rolled sheet is black. It is easy to rust and is also called black iron. It is mainly rolled by high temperature heating. The surface of cold rolled sheet is generally white, more shiny than galvanized sheet. Galvanized sheet is in the ordinary iron plate after a surface treatment - galvanized. In terms of rust and corrosion prevention than “iron plate” strong! Appearance is better than ordinary iron plate! Galvanized iron sheet and white iron (white surface) and color steel (color patterned surface).

2, different physical properties

Hot-dip galvanized sheet than iron corrosion resistance, hot-dip galvanized steel sheet features strong corrosion resistance, good surface quality, conducive to deep processing, economical and practical. Hot-dip galvanized steel sheet is basically a tensile performance is not as reliable as iron. Hot-dip galvanized steel is not as easy to weld as iron plate, the zinc layer will be damaged when welding.

3, the surface of the physical characteristics of different

One is galvanized white, and another is black. Hardness is actually almost the same, but also in the use of performance differences, generally galvanized sheet processing is no longer dealt with, because the surface of the base has a better oxidation, while the iron plate can not be, but also have to do a good job on the surface of the paint or will oxidize.
