Cold Rolled
Steel Sheet in Coil
 |
Product introduction
A cold rolled steel sheet is produced by pickling a hot coil and rolling it uniformly at an appropriated temperature to a thinner thickness. It has excellent surface configuration and superb mechanical properties for use in automobile and electronic appliance production. |

Classification of products
Commercial
Sheet of this quality is for simple bending or
moderate forming. Commercial steel sheet can be
bent flat upon itself in any direction at room
temperature. It has a wide variety of uses, including
automotive panels, electrical home appliances,
drums, pipes, farm implements, office supplies,
building and civil work materials, and as base
metal for various coatings.
Drawing
Sheet of this quality has a greater degree of
ductility and is more consistent in performance
than commercial steel because of higher standards
in production, selection and melting of the steel.
It is suitable for automotive panels, audio-visual
equipment, and heating apparatuses.
Deep drawing
Sheet of this designation should be used when
drawing steel will not provide a sufficient degree
of ductility for fabrication of parts with stringent
drawing requirements, or applications that require
the sheet be free from aging. This quality is
produced through special steelmaking and finishing
practices. It is suitable for automotive front
panels and rear fenders.
Dull finish
Dull finish, which is attained by attaching numerous
fine grains onto the steel surface, is often called
'pear-skin finish' or 'egg-shell texture'. The
grains are made by steel grit blasted roll. The
dull finish is useful in drawing because lubricant
oil can be evenly spread over the entire surface,
thereby reducing the possibility of friction.
The fine grains also help boost paint adherence
and extend the steel life span of the steel.
Bright finish
Bright finish presents high-quality roughness
that is optimal for decorative purposes. The sheet
surface is rolled with fine polished rolls.
Applications
| All kinds of hardware, fittings, parts and accessories, furniture, medical equipment, motorbike and bicycle accessories, lightings parts, etc. |
