Galvanized Sheet Weight Calculator

Galvanized sheet refers to the steel plate with a layer of zinc on the surface.

Galvanizing is an economic and effective anti-corrosion method often used. About half of the world’s zinc production is used in this process in order to prevent the surface of steel plate from corrosion and prolong its service life.

According to different production and processing methods, galvanized steel sheet can be divided into hot-dip galvanized steel sheet, alloyed galvanized steel sheet, electro galvanized steel sheet, single-sided galvanized steel sheet and double-sided differential galvanized steel sheet, alloy and composite galvanized steel sheet, as well as color galvanized steel sheet, printing coated galvanized steel sheet, PVC laminated galvanized steel sheet, etc

However, the most commonly used is still hot-dip galvanized plate.

There are three types of coating surface, namely ordinary zincification, small zinc flower and no zinc flower.

According to the current national standard continuous hot dip galvanized steel sheet and strip (GB / t2518-2008), the nominal thickness of galvanized sheet is 0.3mm ~ 5.0mm, the nominal width is 600mm ~ 2050mm and the nominal length is 1000mm ~ 8000mm.

The galvanized sheet is generally delivered according to the theoretical weight, and the galvanized steel strip is generally delivered according to the actual weight.

Since the galvanized sheet is galvanized on the basis of cold-rolled or hot-rolled steel plate, the theoretical weight of galvanized sheet also includes two parts: one is the theoretical weight of cold-rolled or hot-rolled steel plate (substrate) for processing galvanized sheet, and the other is the theoretical weight of galvanized layer.

You can use the galvanized sheet weight calculator below to calculate the weight of galvanized sheet.

Nominal coating weight range

Coating formApplicable coating surface structureNominal coating weight range (g/m2)
Pure zinc coating (Z)Zinc iron alloy coating (ZF)
Equal thickness coatingN,M,F,R50~60060~180
Differential coatingN,M,F25 ~ 150 (each side)— 

Note: N, M and F are pure zinc coatings. N indicates that the surface structure of the coating is ordinary zinc flower, M indicates small zinc flower, and F indicates no zinc flower; R is the common zinc flower of zinc iron alloy coating.
