This panel supports five major ribs with minor stiffener ribs added for improve rigidity and aesthetics. Because of the panel's 38" width and 36" coverage, the Five Star Panel overlaps one rib of the preceding panel for a weather tight seal. One of the most important features of this seal is the Anti-Siphon Cavity in the purlin bearing rib. This prevents capillary action from transferring water to the underside of the panel. This is accomplished by breaking the surface tension that draws water between objects while providing a channel for the water to drain out.
In order to enhance the lifespan of our product, North Star Metals exploits the benefits of pre-heating all roll-formed panels. Pre-heating increases the elasticity of not only the paint and primer, but the zinc alloys in the galvanic coating as well. This increase in elasticity allows coatings to maintain uniform adhesion throughout the roll-forming process. Having found the perfect temperature for roll forming, North Star is able to produce panels that are drastically less susceptible to micro-crazing and the inherent corrosion.
