About Us

Dueck’s Mechanical Inc. is a family owned business located in Whitemouth, Manitoba, Canada. We have been designing, developing and manufacturing fabric covered steel structures since 1989. Our focus is on quality and service while maintaining reasonable prices. This starts with well trained, qualified staff using high quality North American produced steel and fabric.

The Canadian Welding Bureau has certified Dueck’s Mechanical Inc.’s manufacturing plant to CSA Standard W47.1. This guarantees you are getting superior welds on all welded building components.

Diamond Shelters is also certified to CAN/CSA-A660, a requirement for manufacturers of engineered structures under the National Building Code of Canada. It is your assurance that the material that goes into each part is traceable and meets the specifications stated or required by engineering.

Dueck’s Mechanical Inc. markets its structures under the label Diamond Shelters. Although all business is conducted out of the Whitemouth office, Dueck’s Mechanical Inc. operates in the United States as Giant Supply USA. Diamond Shelters has a growing network of excellent dealers in Canada and the United States to service our many customers. This service includes helping you choose the shelter best suited for you. We have the building that will fit your needs. If not, we may be able to customize our shelters to fit the dimensions or specifications you require. Easy to follow set up instructions are included with each shelter package. Our technical support staff is available to answer any questions that may arise while erecting the shelters. This after sales service provided by Diamond Shelters and our dealers ensures that all structures are completed to your satisfaction.

In 2023, Dueck’s Mechanical Inc. celebrated not only its 34th Anniversary manufacturing Diamond Shelters, but also 34 years of providing Retail and Metal Fabricating Services to our region. Check out what other services we can offer you.
