Mechanical process and pre-treatment:
SMALTODESIGN® panels are "individually tailored" once the feasibility study is completed. Drilling, cutting and welding of the sheets are performed with laser technology and press-bending by a numerically controlled machinery. To assure optimal adherence of the enamel to the steel, the raw panels are pre-treated by immersion into special tanks with specific solvents for degreasing, cleaning, pickling and the application of nickel.
Enamel coating:
The coating process is performed in compliance with the norm UNI EN 14431: the use of acid resistant enamels of class A+ secure the structural and colouristic inalterability from exposure to atmospheric and/or chemical agents.
The first step in production disposes the application of the priming coat (Grund), followed by two successive colour passages with respective firings at the temperature of 830°C.
The minimum thickness of the three enamel layers of SMALTODESIGN® panels is 250 microns.
The desired colour can be chosen from the RAL scale or, alternatively, especially composed and formulated by our SMALTODESIGN® laboratory.
Flatness:
The perfect flatness of SMALTODESIGN® panels is assured by a stiff counter-backing support and a balancing layer of galvanized steel which are hot-pressed to the backside of the panels.
