Cold Rolled Strip Steel , Cold Rolled Steel Sheet Thickness 0.12 - 2.5mm
Description:
Cold Rolled Steel is a mill product made with a high degree of gauge accuracy and uniformity of physical
characteristics. The smooth deoxidized matte finish gives an excellent base for paint, lacquer and enamel.
Box annealing and absence of scale permit stamping and moderate drawing operations. Sheets bend flat
on themselves without cracking. Oiling protects Surface against rust.
The application of surface oil to cold rolled steel sheet is intended to provide protection from corrosion
("rusting") during shipment and warehousing. Because cold rolled steel sheet is prone to rusting, standard
practice is to apply a rust-preventative oil at the exit end of the temper mill (the last processing step).
Rust-preventative oils are different than forming lubricants in that they contain special corrosion-inhibiting additions. In addition to the oil, Wangfa Steel maintains clean, dry environments in climate
controlled warehouses at all its facilities to ensure our coils and sheets arrive to you in prime condition.
Cold rolled sheet products have been available for many, many years, and have been successfully used
for a multitude of applications. Today's cold rolled sheet products are much improved over those used in
the past. They offer better control of thickness, shape, width, surface finish, and other special quality
features that compliment the emerging need for highly engineered end use applications.
