Lester Uni-Rib™ Roof/Siding The Lester Uni-Rib™ panel is an exclusive, colorful line of steel ideal for roofing, siding, and interior linings on Lester® buildings. Uni-Rib™ panels offer you strength where it is needed, plus the good looks you want on your building now and for years to come. The Uni-Rib™ color process provides years of low maintenance beauty, inside and out. Full hard steel (82,000 psi tensile strength minimum) provides resistance to deformation from wind, snow, ice and hail. G60 hot-dip commercial galvanized zinc coating on both sides of panel provides additional weather resistance. A heavy zinc phosphate coating, plus its seal coat, further enhance corrosion resistance and primer adhesion. Baked-on primer coating ensures adhesion of finish coat and protects against corrosion. Siliconized polyester, baked-on paint finish provides rich, durable outside surface color and helps panels resist fading and chalking in sunlight. Panels are warranted not to chalk or fade excessively for 30 years (graduated). In addition, paint is warranted to adhere to the panels without cracking, checking or peeling for 30 years under normal weather and use conditions. See warranty for complete details.
