PRODUCT INFORMATION
Hard, High Tensile Strength Steel
Best Rib's hard 29-gauge steel is manufactured to ASTM A792 Grade 80 specifications for a minimum tensile strength of 80,000 psi, allowing Best Rib to stand up to the most severe weather conditions including ice, driving wind, or heavy snow.
Galvalume Coating
A heavy, hot-dipped zinc-aluminum coating is applied to the base steel on both the bare and painted products. This coating offers maximum corrosion protection and helps assure low maintenance, durability and edge protection with a limited 25-year warranty.
Acrylic Coating
Available on bare only, is a clear organic surface treatment applied over the Galvalume coating. The surface treatment is essentially invisible and provides excellent characteristics to improve the performance and applicability of the unpainted Galvalume sheet. Installation is easier and safer since no oils are applied to either the sheet or the forming rolls. Equally impressive is the performance of the material in regards to hand marking and non-uniform darkening when stored at a job site.
Siphon Groove
Best Rib is designed with unique siphon groove drain channels that guard against wind, rain, and snow-eliminating leaks. The siphon groove on the underlap of the panel interlocks with the overlap of the next panel. This adds strength to the purlin bearing leg. The design permits a free-flow water runoff, channeling out any water that might be forced into the snug-fitting lap.
Life Cycle Cost
Best Rib is the best investment for your dollar. Backed by a limited warranty on the color coated panels, Best Rib is less prone to wind damage and deterioration from the elements than traditional roofing products. The low maintenance and long-lasting beauty make Best Rib the cost-effective alternative.
Environment
Looking to the future, we all need to be concerned about preserving the environment. Many asphalt and tar-based roof systems are not recyclable, which contributes to the growing landfill problems. Steel is 100% recyclable and all of AMW's steel panels contain recycled steel. Because the Best Rib is durable and lightweight, it can be retrofitted over existing shingles or built-up roof systems. This eliminates the need to remove or dispose of the existing, non-recyclable roof.
About Metal Panels
The two primary components of any steel panel are substrate and coating system. Many combinations of substrate and coating are available. The quality and performance of these two components are critical to the longevity and performance of the panel.
About Coatings
The coating system, or paint, for metal panels is also an important consideration. The surface panel will constantly be exposed to environmental elements – ultraviolet sun rays, acid rain, dirt, etc. Over time, these environmental conditions will break down the coating, resulting in panel fade and chalk.
