Galvanized amount of rolled steel sheet

1.The amount of galvanizing is a common and effective method to express the thickness of the zinc layer of the galvanized sheet. The common unit of galvanizing amount is g/m2. There are two common types of constant thickness galvanizing and differential galvanizing. In short, galvanized coils have different amounts of galvanizing on both sides (the same or different amounts of galvanizing on both sides).

2. Mechanical properties of galvanized coil

Tensile strength and flexural strength are common properties of rolled steel sheets. Tensile properties: Generally speaking, only structural, tensile and deep drawing galvanized sheets have tensile properties requirements. Bending: is the main item to measure the process performance of sheet. However, the requirements for various galvanized sheets in national standards are not consistent.

3. Chemical composition of galvanized coil

Chengdu galvanized coil has strict national standards for the chemical composition of galvanized substrates. However, the chemical composition of galvanized coil produced in different countries will vary.
