| Panelsinstretchedplate Panels obtained by: Galvanized steel sendzimir DX52D+Z140/200 on which a plastic deformation (stretching) is made in order to obtain several typologies of rhomboid, square, round mesh on different thicknesses and stand width The so obtained squares undergo the following manufacture of cutting and folding through pressing or folding pressing depending on the fact it deals with standard panels or special panels by request. The process ends with the powder coating on requested colours with a thickness of 60-80 mrc. The panels belong to the zero class of reaction to fire because included between the materials listed in D.M. 14/01/85 (G.U: n. 16 of 19/91/85) to which is automatically given the zero class without being subjected to the proof of non combustibleness and to D.M. of 26/06/84 (G.U. n. 234 of 25/08/84) which considers not influential the layers of superficial finish composed by varnishes and/or paintings with a thickness inferior to 0,6 mm sticked to non combustible materials. |
