10) How can I process Steelcolors® sheet?
Steelcolcors can be guillotine cut, sheared, drawn, trimmed, bent, flexed, bolted, riveted, glued, and welded, as long as the proper equipment is applied to each operation. Ask for the User Guide.
11) Where can I buy equipment and accessories to process Steelcolors®?
As to equipment applied for processing there are specialized companies that manufacture and trade bending press, calender, hydraulic press, and guillotine, which can be easily purchased on the market.
12) Does Steelcolors® support repainting or touch-ups?
Yes, repainting may be needed for a number of reasons. Since this type of painting is to dry out at the atmosphere, it will not present the same level of performance as the one that is thermally applied and cured at the factory by means of a process named Coil-coating.
Painting manufactures, which are the suppliers for this kind of process, have the capacity to produce compatible paints, and with the same shade.
For small amounts, which purpose is the touch-ups, one shall pay special attention so that the paint is duly compatible with the original painting (Polyester Resin). One shall do an initial test with the paint by applying it at a small and hidden area, prior to start painting the entire area of purpose.

- Non-combustible
- Greater Mechanical Strength
18) What is the advantage of Steelcolors® if it is compared against the pre-painted aluminum solid sheet?
- Lower Cost
- Greater Mechanical Strength
19) Under the circumstance of a fire, what happens to Steelcolors®?
