Section 01

Primary Structural Frame

The primary frame is the backbone of your building. It consists of heavy-duty galvanized steel columns and rafters engineered to support the entire weight of the structure and withstand external loads.

12-Gauge vs 14-Gauge

14-gauge is the industry standard. 12-gauge is thicker and stronger, recommended for high-wind and heavy-snow areas.

Galvanized Coating

All our framing is galvanized to prevent rust and corrosion, ensuring a lifetime of structural integrity.

Engineered Connections

Precision-drilled holes and high-strength bolts ensure every connection is secure and easy to assemble.

Heavy-Duty Galvanized Steel Framing

Purlins

Horizontal members that support the roof panels and transfer loads to the primary rafters.

Girts

Horizontal members that support the wall panels and provide lateral stability to the columns.

Eave Struts

Located at the intersection of the roof and wall, providing a transition point for panels.

Bracing

Diagonal members that provide additional stability against wind and seismic forces.

Section 02

Secondary Framing

Secondary framing consists of the purlins, girts, and eave struts that span between the primary frames. These components provide the attachment surface for your roof and wall panels.

  • Precision-formed galvanized steel
  • Optimized spacing for maximum panel support
  • Easy bolt-together assembly

We offer both 14-gauge and 12-gauge galvanized steel framing. 14-gauge is the industry standard (2.5" x 2.5"), while 12-gauge is thicker (2.25" x 2.25" but with thicker walls) and stronger, recommended for high-wind and heavy-snow areas.

We offer both, but we highly recommend vertical roof panels for better drainage and structural integrity. Vertical panels allow snow, rain, and debris to slide off easily, whereas horizontal panels can trap moisture and debris.

The gauge refers to the thickness of the steel. 29-gauge is the standard thickness, while 26-gauge is thicker and more resistant to dents and structural stress. 26-gauge is often required for commercial buildings.

Absolutely! You can mix and match from our 15+ color options for the roof, walls, and trim at no extra cost.

Yes, we provide generic engineered drawings for all our buildings. Site-specific wet-stamped drawings are also available if required by your local building department.
