Quality and Safety:

• Certified Design: Our doors have been rigorously tested and are certified to the UL325 standard, ensuring they meet the highest safety and performance requirements.
• Expertly Welded: Diamond Doors is certified with the Canadian Welding Bureau, and all welding is completed to the CSA W47.1 standard, guaranteeing superior quality and craftsmanship.
• Cables: Diamond Doors uses highly specialized cables that utilize an extremely fine weave and fiber core for exceptional lifespan. These cables have 18 braids of 7 strands per braid and a flexible nylon rope center. Common competitor door cables use a 7×19 cable, which is 7 braids with 19 strands per braid. Our design has increased flexibility and longevity. We are committed to creating quality products, which is why we go above and beyond, engineering our doors with a 10x cable safety factor. Using more cables translates to less loading per cable, helping to better distribute door loads and extend cable life. Our unique cable lift system creates an offset during lift, preventing the cable from ever “overlapping” or coming into contact with itself (the primary reason for shortened cable life). Our innovative system guides the cables around the driveline like a candy cane. Our cables are not affected by wind and wrap consistently every time.
