DGI Dome Frames

We offer the highest quality dome structure available, manufactured from high-grade structural steel. All frames are powder coated with a white finish—direct from the factory at no extra cost.

DGI manufactures with thick gauge structural-rated steel.

Our standard frame system is pre-engineered to withstand the following:
Wind Speed – 125 to 150 miles per hour, according to dome size
Snow Load – 20 to 30 pounds per square foot
Hanging Weight – 250 @ 50 pounds from each of the 5 top hubs. This allowance can potentially increase and can vary based on placement of hang.

Heavy Duty Upgraded
While our current standard frames are considered heavy duty, we will run a “site/use specific engineering report” and manufacture custom heavy duty frames.

The relationship of the three loads above (wind, snow, and hanging weight) is like a mobile. If one of the three loads is adjusted, the other two are affected. For example, if there is zero hanging weight in the dome then the snow and wind loads will be increased.

These are pre-engineered calculations. The actual performance can vary depending on specific region’s safety and seismic requirements, in which case, we cannot guarantee our pre-engineered calculations will qualify your region. You may need a “site-specific” engineering report created for your location.

This report is provided starting at a base cost of $1,500.00 and can range up to $2,500.00 or more, depending on the area’s requirements, size of the dome, and the scope of the project.

If the geographic area of the project calls for a stronger dome, we will custom engineer and manufacture frames to meet the specifications.
