Bulk storage dome

Storage Domes and Barrel Buildings for Bulk Solids

Proven performers

For 50 years, our patented domes and barrel buildings have proved to be the most economical, efficient and reliable structures ever built for storing bulk solids … from road salt to fertilizer, sugar, chemicals, powdered metals and cement.

Features and materials that benefit your operation and the environment

High performance – Built to withstand the worst weather and to meet the most stringent building codes

An ideal shape – Mirrors the shape of piled bulk solids; naturally deflects high winds and sheds heavy snow; circular footprint eliminates wasted space and leftover material in corners and makes it easier to rotate materials

Self-supporting panelized construction – Results in a building that is much stronger than conventional flat- or peaked-roof structures, with huge clear spans and no need for internal pillars, supports, trusses or beams

Durable, long-lasting materials – Roofing materials are warranted for 40 years or more; galvanized steel hardware and other materials are carefully chosen to ensure a corrosion-resistant storage system that protects your investment from the elements and requires little or no maintenance

Impenetrable pads and seals – Prevent product loss from leaching and protect the environment from contamination

Corrosion-proof ducts – Eliminate trapped moisture and fumes

Strong, reinforced concrete retaining walls – Last longer and stand up better to material pressures and equipment mishaps than wooden retaining wall systems; walls are sealed to prevent corrosion

Large entrance doors and canopies and unobstructed interiors – Make loading and unloading safer, faster and easier

Barrel buildings – structures formed by “cutting a dome in half,” stretching it out, and filling in the center section with laminated lumber infill panels – can be:

  • Made to virtually any length
  • Partitioned to accommodate multiple materials
  • Custom-designed to fit a particular site or application
  • Expanded at any time

Cost-effectively produced and quick to install

Our domes and barrel buildings are pre-engineered and prefabricated at our manufacturing facility in a climate- and quality-controlled environment.

The floating concrete retaining wall is founded at grade, eliminating the need for expensive and time-consuming below-grade foundation construction. And the modular prefabricated wood panels can be bolted together in days.

This gives you a higher-quality building at a lower cost – a building that goes up quickly and easily, on time and on budget.

Suitable for a wide range of applications

Infinitely adaptable

Size and capacity:

Standard domes range from 35 to 150 feet in diameter … and the size of our barrel buildings is limited only by the amount of land you have available. Capacities can range from 500 to more than 100,000 tons.
