Description
Normally, steel sheets are divided into two categories of hot and cold plates, which are recognized based on their production methodology. One type of the cold plates is galvanized sheet, made from cold-rolled steel sheet. It should be noted that galvanized sheet is made from cold-rolled sheet and cold-rolled sheet is also made from black sheet.
Types of galvanized sheets
The classification of galvanized sheets depends on various factors, one of which is the final shape of the manufactured product. Galvanized sheet is produced in two forms, rolls and sheets, each of which has its own dimensions and standards.
The production method of galvanized sheet is also a determining factor for the types of products available, including shadow line sheet, gable sheet, shutter sheet, steel deck, colored sheet, etc.
Each of these products are produced based on peculiar specifications and have different applications.
After galvanization, some ridges appear on the sheet, known as spangles. Based on these spangles, the galvanized sheets are divided into “no spangle, regular spangle, big spangle and small spangle”.
The specification applied by each factory for the production of galvanized sheet provides specific characteristics to the product, based on which we will know various types of galvanized sheet. These specifications are: American standard ASTM A653/A653M and European standard EN 10346 and DSTU EN 10346.
