Knowledge about maintenance of galvanized coil

1. Packaging

Divided into two types: galvanized sheet cut to fixed length and rolled galvanized sheet packaging Generally speaking, iron sheet packaging is lined with moisture-proof paper and tied with an iron waist to prevent the galvanized sheets inside from rubbing against each other.

2. Specifications and dimensions

The relevant product dimensions (described below) all list the recommended dimensions thickness, length and width of galvanized sheet and their allowable defects. In addition, the width and length of the board and the width of the roll can also be determined according to the user's requirements.

3. Surface

General situation: Galvanized sheet has different profiles due to the different treatment methods in the coating process, such as general spangle, fine spangle, flat spangle, no spangle and phosphating treatment profiles. Galvanized sheets cut to fixed lengths and galvanized coils shall not have defects (listed below) that affect their use, but rolled sheets are permitted to have non-deformed parts such as welded parts.

4. Galvanizing amount

Galvanizing Scale Value: Galvanizing is a widely used and useful method to indicate the thickness of the zinc layer of galvanized sheet. different) The unit of galvanizing is g/m2.

Galvanized steel coil is very popular in various environments and has a long anti-corrosion life, but the anti-corrosion life in different environments is different. The processing cost is low, and the anti-rust cost of galvanized steel is lower than other coatings. durable. In suburban environments, the standard galvanized anti-rust coating will last for over 50 years without maintenance. In urban areas or offshore areas, the standard galvanized anti-rust coating will last for 20 years without maintenance. good reliability. The galvanized layer and the steel are metallurgically combined and become part of the rigid surface, so the durability of the coating is relatively reliable. The coating has strong toughness, and the galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
