Details of Galvanised steel coil :
Hot Dipped Galvanized Steel Sheet in Coil (GI) is produced by
passing the Full Hard sheet which has undergone the acid washing
process and rolling process through the zinc pot, thereby applying
zinc film to the surface. It has excellent corrosion resistance,
paintability, and workability due to Zinc’s characteristics.
Usually, hot-dipped galvanized steel sheet and galvanized steel
coil process and specifications are basically the same.
Surface Treatment Of Galvanized Steel Coil:
| Surface treatment type | Code | Feature |
|---|
| Chromic acid treatment | C | Good corrosion resistance, suitable for bare state |
| Chromic acid treatment + oiling | S | Good corrosion resistance |
| Phosphoric acid treatment (including sealing treatment) | P | A certain degree of corrosion resistance, good paint performance |
| Phosphoric acid treatment (including sealing treatment) + oiling | Q | It has certain corrosion resistance, good paint performance, and
prevents rust during transportation and storage |
| Phosphoric acid treatment (excluding sealing treatment) | T | A certain degree of corrosion resistance, good paint performance |
| Phosphoric acid treatment (excluding sealing treatment) + oiling | V | Have certain corrosion resistance, good paint performance, and
prevent rust |
| Oiled | O | Prevent rust during transportation and storage |
| No treatment | M | Suitable for immediate painting |
Chromate treatment of galvanized steel coils is also called
passivation treatment. Through passivation treatment, the surface
structure and gloss of the galvanized layer can be improved, the
corrosion resistance and service life of the galvanized layer can
be improved, and the bonding force of the coating and the base
metal can be improved.
The purpose of oiling galvanized steel coils is a protective layer
is formed on the surface of the steel coil to prevent the surface
from rusting.
Application of galvansied steel coil :
Galvanized steel coil has a wide range of applications, and its
advantage is that it has a long anti-corrosion period. It is mainly
used for home appliances, office panels, roof sheets, automotive
panels, construction and substrate of prepainted steel coils.
Car board
The use of automotive plates must first be stamped and formed, and
the steel plate is stamped into the required shape and size of the
part.
Then spot welding, as an important welding method for thin plate
connection, has a wide range of applications in the manufacturing
industry, especially in the automotive industry.
Galvanized roof sheet
The performance requirements of galvanized roof panels mainly
include the mechanical properties of the material (tensile
strength, yield strength, elongation), coating performance (coating
type, coating thickness and coating adhesion)
Home appliance office board
Including air conditioners, washing machines, refrigerators,
photocopiers, etc., household galvanized sheets are mainly used for
general forming applications and stamping.
Substrate
Another use of galvanized steel coils is to be used as the
substrate of prepainted steel coils. prepainted steel coils have
polyethylene coatings than galvanized coils and are more durable.
