Color Coated Steel Coil
Contents |
[edit] Specification
Colour coated steel coils are painted in a variety of colours for aesthetic and protective purposes. Coatings help prolong the lifespan of the steel by protecting it from corrosion and damage. A variety of standard colours, as well as bespoke colours and design are available. The base metal is galvanised steel, cold rolled steel and galvalume steel, typically between 0.2 mm and 1.2 mm thick, with a variable width between 600 mm and 1,250 mm.
[edit] Uses
Steel coils are used in numerous industries for a variety purposes, in the construction industry, as a roof or cladding material, and the automotive industry, for interior and exterior applications. Colour coated steel coils can be seen on painted roofs, fenders, hoods, bumpers, and door panels as well as in furniture, lamps, and general consumer goods.
[edit] Manufacture
The procedure of making colour coated steel coils involves three steps:
- Step 1 - The base metal is cleaned and pre-treated to remove rust, oil, and other contaminants.
- Step 2 - A primer coat is applied to help the paint adhere to the metal surface. Once dry, the coil is then fed to a painting line to be coated with one or more layers of paint.
- Step 3 - After application, the coil is oven-cured to guarantee a lengthy-lasting finish and then quality checked.
[edit] Benefits
- Durable.
- Resistant to deterioration.
- Easier to keep clean and maintain.
- Simple colour selection.
- Protection against the elements.
[edit] Quality checks
Quality checks are a crucial part of any manufacturing process, and that is certainly true for the creation of colour coated steel coils. There are a number of different tests which can be used to assess the quality of the steel coils, including tests for thickness, width, flatness, colour uniformity, gloss level, and so on. By carefully conducting these quality checks each and every stage of production, manufacturers can ensure that their products fulfil the highest standards.
