Technical Information on DeMuth's Steel Domes
The steel domes are shipped in stacks of pie-shaped steel sections, ready for assembly on the job-site. Panels are radiused and their edges are roll-formed into channels at the factory. These are then nested together and bolted together during assembly resulting in a rigid and beautiful free-standing structure. They can be used as an architectural detail or can become an integral part of the building structure, providing a breathtaking inside view.

Domes are available with a base diameter from 10' to 36'. They can be produced as perfect hemispheres or can be formed into more exotic shapes.

The domes are typically manufactured from 24 gauge premier galvanized steel which can be prefinished with a wide range of colors.

Installation of these domes is quick and surprisingly economical.

Coppertunities - Copper Dome Roofs

DeMuth has been manufacturing hemispheric dome roofs since 1946. Traditionally, these roofs were used on tower silos. The unique shape of this roof caught the interest of many architects and in 1979 we started manufacturing a premium hemispherical dome roof for a variety of applications such as churches, day care centers, commuter transit stations, recreational theme parks, and private homes, among others.

The unique feature of DeMuth’s hemispheric domes is that it is structurally self-supporting. Eliminating the need for a superstructure, installation of the DeMuth dome is quick and easy.

Over the years, architects have used DeMuth domes made from a variety of materials and colours. The one metal asked for frequently that could not be used was copper. To maintain the structural integrity of the self-supporting dome meant that only very hard, high tensile materials could be used. Copper, being a soft metal, meant that it was not the best choice as a material for the hemispheric dome even though it offered a very attractive patina as it aged and would outlast many other types of materials.

Leading architectural firms in North America, by their strong interest, moved copper dome roofs higher on our agenda. DeMuth sourced suppliers around the world and found a copper strong enough to be used in our self-supporting hemispherical dome roof. We are now able to offer the architectural industry a dome roof in 20 ounce, ¾ hard copper material.

If your clients are looking for a unique roof in shape and material, offer them a DeMuth copper hemispherical dome roof!

Mobile-T International

When is a silo not a silo? When it’s used to house a cell tower!

Mobile-T International was very aware of the aesthetics around Arvada, Colorado where they wanted to erect a cell tower. After all, this is farm country and a cell tower would not enhance the landscape. And so they came up with the clever idea of putting their cell towers inside farm silos!

DeMuth Steel supplied the silo hoops, the fixed ladder that’s inside the silo to make it easy to maintain the cell tower itself, as well as special doors and frames. Rather than the traditional steel roof, this one is made of fiberglass so it doesn’t interfere with the transmission signals from the tower.

… another innovative way to use stock products

 DeMuth goes Hollywood (sort of)

Just when we thought we'd seen it all when it comes to the many creative ways people use our hemispherical dome roofs, along comes a major promotional event in California.

Adidas commissioned Nadeau Ice to build them an igloo to promote their new Climacool footwear. And what place is colder than an igloo! Building an igloo is a challenge by itself but when you add in the 80F+ climate of Santa Monica in California, the fact that thousands of people would be coming and going inside the igloo to see the new product line, and the two-week timeline to get everything ready for the product launch, it called for some real talent.

Here's how they did it. The base for the igloo used one of our dome roofs. It took 4 people, 9 man hours and 27,000 pounds of snow and ice to build the igloo. The igloo was first assembled, double insulated and painted in Chicago and then re-assembled on-site in Santa Monica.

Company president, James Nadeau, was very pleased with the co-operation of everyone involved in this project, including DeMuth (of course), "...who couldn't have been more accommodating." If you're interested in seeing more photos of the igloo project from start to finish, visit their web site at www.nadeauice.com.

What's next for the DeMuth dome roof - a movie? We'll see.
