Quality

1

Commercial Quality
The commercial quality cold rolled steel sheets and coils are made of carefully annealed low carbon steel coils. They have a good surface finish, workability and excellent flatness.

2

Drawing Quality
This quality is used for applications that require drawing properties that are better than those of the commercial quality. They are produced from high grade materials by carefully controlled manufacturing process.

3

Deep Drawing Quality
Made from strictly selected materials and manufactured with the most exacting quality controls, this quality has the highest attainable quality for drawing use.

 

 Surface Finishes

1

Dull Finish (Matte Finish)
This does not have any luster and is actually made rough intentionally so that the lubricant will stick to it during press forming, thereby facilitating fabrication. This finish is also suitable for paint adhesion. With these characteristics, cold rolled steel sheets and coils with this finish are most extensively used.

2

Commercial Bright Finish
The smooth texture of the surface makes it best suited for metallic plating and coating.

 
 Edges

1

Edges produced during the hot rolling process in the manufacturing of hot rolled coils.

2

Slit Edge (Trimmed Edge)
Edges produced by trimming or slitting at the final stage after the cold rolling process.

 
 Oiling

1

Cold rolled sheet coil are oiled by the Electrostatic Oil Coater at our recoiling line in order to provide maximum protection against rusting. However, order are accepted for products without oiling.

2

DOS coating (FDA approved) are also available for cold rolled steel coils to be used in making food grade packaging containers.
