Pre-painted

Prepainted steels

These products consist of a steel substrate to which an organic coating in the form of paint (or powder) is applied by a continuous method (coil coating). This allows these products to encompass a huge variety of features: the different mechanical properties provided by the steel substrate, the highest levels of corrosion resistance, the availability of multiple colors, the variability of gloss and surface finish, environmental compatibility, and economic and energy savings in the overall manufacturing process.

The material that makes up the substrate is a steel product with or without a metal coating, depending on the use:
ZINCED: this is the most commonly used substrate, as the zinc coating protects the steel from corrosion

COLD LAMINATED: this is never used if there is a risk of corrosion (so typically only for interior use).

Depending on the use, the paint/enamel layer should be tuned at the time of purchase.

The system constituting the coating can be single-layer, with certain requirements, or applied as a primer in preparation for later applications. It can be multilayer, comprising a base layer, possibly one or more intermediate layers and a finishing layer with all the necessary requirements.

Technical supply conditions:

The standard specifies the requirements of flat steel products continuously coated with organic material (coated strips). In particular, it specifies performance requirements. The products considered are wide strips, sheets cut from wide strips, sheared wide strips, rolled strips less than 600 mm wide, and the strips (made from sheets or strips).

The name of these steels shall include the full description of the steel substrate, the type and weight of the metal coating (where present), the symbol for the organic material applied to the top surface, and, where required, for that applied to the bottom surface, the nominal thickness in µm of the organic coating applied to the top surface and, where required, that applied to the bottom surface.

It is always necessary to specify whether the nominal thickness of the desired prepainted steel is inclusive of the organic coating applied to the two faces or whether it is instead to be understood as the thickness of the substrate and metal coating excluding the organic coating (as the standard prescribes).
