• Remote Access: Enjoy the convenience of a fully automated door with our auto-lock option and remote opener packages. Enter and exit your building with ease at the push of a remote button, just like your garage door at home.

• Self-supporting Header: The optional Self-Supporting Header is used for applications where the building does not have the strength to hold the door’s weight and loads and/or is used to extend the clear opening past the roofline, increasing available overhead space.
• Stainless Steel Pkg: The stainless-steel frame option is a great option for high humidity or corrosive environments such as dairy barns and poultry barns. Diamond Doors offers many different grades of stainless steel. Most common is the 300 series in 304, 304L, 316 and 316L. Also included are stainless steel hinges, hinge pins, and lifting cables.

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.
