Other companies only use 33 KSI, Grade C steel panels standard. In addition to our great quality, we stand behind some of the best warranties in the business! Our workmanship is guaranteed for one year, while other companies offer only a 90 day warranty on workmanship. Our steel panels are guaranteed for 40 years for film integrity, 30 years against fading, peeling and flaking, and 25 years against rust-through perforation.
