McElroy Metal ThermoForms all Max-Rib galvanized metal panels for increased longevity, visual appeal and value.
The ThermoForming process increases the ductility of both the paint coating and the zinc in the metalllic galvanized coating. This process significantly reduces tension bend cracking in the panel’s paint and metallic coating. This in turn reduces the risk of premature corrosion of roof and sidewall panels.
Tension-bend cracking is not an issue for Max-Rib Ultra, because it is coated with a PVDF coating. PVDF coatings remain flexible regardless of the temperature during the roll forming procedure.
The ThermoForming process incorporates a special heater chamber to raise the inner and outer temperatures of the coil sheet to > 120F. The process increases the ductility of the outer paint coating as well as the ductility of the zinc in the inner metallic galvanized coating. This extends the life, the visual appeal and the value of Max-Rib Utility, Max-Rib 60 and Max-Rib 90 building panels.
ThermoForming is not available at all McElroy locations. Please inquire with your McElroy Customer Service Representative for more information.
