Framing Systems

The gable roof design features two sloping sides meeting at a central ridge, forming a triangular shape at the end walls. This versatile and cost-effective style is ideal for garages, shops, barns, warehouses, and residential use.

The unsymmetrical gable roof features an off-center peak, with one side of the slope longer than the other. This design is ideal for sites requiring an offset roof peak for functional or aesthetic purposes. 

A single slope building features a roof that slopes in one direction, creating a single, inclined roof plane from one side of the structure to the  other.

A lean-to building is a single-sloped metal structure attached to the side of an existing building, using the main structure’s wall for roof support. It provides a cost-effective additional storage or shelter, expanding the building.

The purlin spans between frame lines and is spaced at intervals of up to 5 feet, depending on local building code requirements. 

 Joists are used to span between frame lines when larger bay sizes are needed, typically ranging from 40 to 60 feet. 

The eave strut is installed at the eave—either at the gable end of a structure or at both the low and high sides of a single-slope building. It spans between frame lines and sits atop the rafters. 

Girts are secondary wall members that span between frame lines and are vertically spaced from the slab to the eave in accordance with local building codes. C sections are commonly used for framed openings, header support, and for attaching metal wall panels to masonry and other structures. 

Structural support column that gradually grows from the base of the column to the top of the column. 

Structural support column that maintains a consistent width from the top to the bottom. 

Metal building bracing system that are installed in an “X”,pattern between the columns. It runs from the base of one column to the top of the adjacent column. 

Structural bracing system that uses a frame consisting of two vertical columns connected to a horizontal beam. Typically these are used when a door or window needs to be placed within the bay that requires bracing.

Also known as Wind Column

A vertical member on a sidewall that transfers wind loads to the foundation. It can be placed adjacent to or slightly offset from the main frame column, depending on design. 

Horizontal supports attached to building columns, running around the building's exterior without touching the columns. This creates a gap between the column and the wall panel, allowing the girts to bypass the columns completely.

Horizontal supports installed directly against the exterior columns, making the outside face of the wall panels align perfectly with the column surface, creating a smooth and even appearance
