First class workmanship by staff, certified by the Canadian Welding Bureau, go into making each Diamond Shelter. The results are components that fit together well, joints that are smooth and do not need to be taped with duct tape and very little, if any, on-site fabrication when setting them up. North American made steel and fabric go into all our shelters. This ensures the steel and fabric in your Diamond Shelteris of a consistent high quality. Diamond Shelters are certified to CAN/CSA-A660 standards. This is a quality control program that is your assurance that the material that goes into each shelter part meets the specifications stated or required by engineering. Finally, after determining the origin of a competitor’s steel and fabric, and the level of certification of the manufacturer’s plant, compare the design of a Diamond Shelter with a competitor. Find answers to the following questions. What is the rafter spacing? What is the diameter of the major structural members? What is the shipping weight? How many purlins (Single Hoop) or cross braces (Welded Truss) are used in the shelter?
