80’ to 120’ Wide Welded Truss  Diamond Shelters


  • 110' FreestandingDiamond Shelter Welded Truss structures are designed for those applications that require wider clear spans site-specific and engineering. They can be used for: commercial warehousing; manufacturing facilities; highway salt and sand storage; sports training facilities; horse riding arenas; composting facilities; machinery storage; hay, straw and grain storage; and livestock facilities. 


All Diamond Shelters start with well trained and qualified staff, certified by the Canadian Welding Bureau. We also use high-quality North American produced steel. The steel, because it is produced in North America, has very consistent yield and tensile strengths.

80' Freestanding All components in a Diamond Shelter are precision manufactured. This translates into a structure that fits together better; that meets or exceeds load requirements; that is more aesthetically pleasing; and that requires little, if any, on site fabrication.

For superior structural strength our Welded Truss Diamond Shelters are designed with multiple rows of cross bracing rather than straight purlins.

Bolt together joints make rafter and cross bracing easy to assemble. All joints or connections contacting the cover are smooth. No taping of joints is required.

The 80’, 90’, 100’, 110’ and 120’ Welded Truss shelters come in Freestanding and High Profile models. They all can have either 8’, 10’ or 12’ rafter spacing.

Optional Powder Coating in our standard grey color, provides a superior finish that is tough, durable, attractive and environmentally friendly. Powder Coating is also available in other colors as an additional option.

Take a look at the Welded Truss Options that are available. They include screw pile mounting plates, half moon ends, awnings, end wall mesh vents, ridge vents, flame retardant covers and insulation packages.
