  • Uniform surface finish

  • Tight thickness tolerances

  • High degree of formability

  • Outstanding shape control (flatness)

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, Curtis 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.

Commercial Quality

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 implement, office supplies, building and civil work materials and as base metal for various coatings.

Drawing Quality

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 Quality

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. 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.
