Galvanized Steel Sheet Quality And Performance

1. Specifications and Dimensions

The standard galvanized coil factory is marked with its standard length, thickness, width and allowable deviation value; if the customer has special requirements, the width, length and thickness of the galvanized sheet can be customized according to customer requirements.

2. Packaging Design

Galvanized coils are generally packaged with iron sheets, lined with moisture-proof paper, and tied with iron waists. The binding is firm and prevents the inner galvanized sheets from rubbing against each other.

3. Appearance

Galvanized coils have different surface states due to different treatment methods in the coating process; such as ordinary flat spangle, non-spangle and phosphating surfaces.

4. Galvanizing amount

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).

5. Mechanical properties

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.

6. Chemical composition

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.

7. Plate shape

There are two indicators for measuring the shape of rolled steel sheets, namely flatness and sickle curvature. There are certain regulations for the flatness of the steel plate and the allowable value of the camber.
