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 |
Mill Edge
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. |
