Thermoforming

Long-term customer satisfaction is our top priority at McElroy Metal. As a result, we're constantly looking for ways to do things better, even if it means making investments in new equipment. Thermoforming (or warm forming) is just one example of our customer commitment.
Traditionally steel panels have been manufactured from steel at room temperature. While that process worked for decades, new advances have proven that warming the steel prior to production can result in a better product with a longer life expectancy for Silicone Modified Polyester (SMP) paint systems.
Thermoforming technology is just one more thing we're doing different than our competitors to earn your business.
Factory Applied Anti-Condensation Membrane
Max-Rib roof panels with McElroy's MoistureLok, offer a great option to address condensation challenges. The design of our MoistureLok product traps moisture and then releases it back into the air as natural humidity once conditions go back below the dew point.
