Creating Galvanized Steel Coils
As a leading galvanized steel coil manufacturer, Jiangsu Mittel Steel employs best industry practices in the creation of our products. Our loyal customers can rest assured that Sinowell Metal features exacting processes to produce our hot dipped galvanized steel coils. During the production process, our engineers place cold rolled steel coils through our uncoiler. The steel travels through an accumulator where it undergoes pretreatment.

In order to guarantee its quality, this steel coil and sheet is severely tested on varied standards. We offer this steel coil and sheets in a range of specifications as per the demands of customers.
Features:
- High strength
- Elevated durability
- Hardness & ductility
- Compact design
Atmospheric Corrosion Resistance:
- Based on many year atmospheric corrosion R&D tests, it is estimated that 55% Al-Zn sheet will outlast G90 galvanized by two to four times in marine, industrial and rural atmospheres. 55% Al-Zn panels are still rust-free after 30 years in all but the severe marine environment. The estimated life of the 55% Al-Zn coating (years to first rust) based on these 30-years tests ranges from 14 years to 40 or more years.Thickness range is 0.2mm to 0.95mm.
We guarantee our products meet stated criteria and grades that include primary standards such as:
ASTM A653M
This is the American standard for cold rolled materials.
JIS G 3302
This is the Japanese material standard associated with hot dipped galvanized steel coils.
