Diamond Shelters — Manitoba-Made Since 1989

Diamond Shelters is manufactured by Dueck's Mechanical Inc. in Whitemouth, Manitoba. They've been designing and building fabric-covered steel structures for over 35 years. The catalogue covers clear-span widths from 15 feet through 160 feet, in any length you need, with 12oz polyethylene-impregnated fabric available in multiple colours. They have an extensive dealer network across Canada and the US, ship complete setup instructions with every kit, and have technical support staff that actually answers the phone.

None of that replaces a crew with manlifts on your site. Diamond's dealer network is broad but not every dealer offers installation, and on the larger sizes — 40-wide and up — even competent owner-builders struggle without the right equipment. We install the entire Diamond range. Flat-rate pricing identical to the canonical table on our homepage. No brand surcharge.

Yes — every Diamond width from 15 ft through 160 ft clear span. Most of our Diamond work comes from customers who bought through the Diamond dealer network and the dealer doesn't install in their area. Diamond's kits are well-documented and forgiving to assemble, which makes them one of the faster kits we install once the right equipment is on site.
