TH54194B - Structural panel - Google Patents

Abstract

This invention involved In general, with that of the structural panel in the form of 10 elongated metal roof panels. And have four longitudinal and spaced ridges. 12/14/16/18 adjacent pairs of longitudinal ridges, such as 12 and 14, are connected by segments. Trays 20 sections, trays 20 each, including small grooves that extend horizontally. 22 small grooves are in the form of grooves and ridges, such as 23 and 25, respectively. The smaller grooves are designed to strengthen the unstable trays. In other words, 20 and also For beauty In order to have an attractive appearance and It has also been found that the groove size Small results in removing "oil canning" if the surface of the material is distorted by expanding sheet metal in General rolling forming
