Building Systems

Steel Framing Systems

Every frame is designed individually and manufactured specifically to meet the requirements of your building.

We have the engineering expertise to design interiors with wide-open spaces, unusual ceiling heights and extreme load requirements.

Our frame designs can accommodate cranes, monorails, mezzanines and other custom requirements.

Clear-Span Frame

Clear span frames are recommended for buildings where unobstructed interior space is required.

Common uses include aircraft hangars, arenas, tennis centres, soccer centres, riding arenas, manufacturing facilities, warehouses, offices, and retail stores.

Column-free interiors also provide the space required for material handling and crane systems.

Lean-To Framing System

Lean-To Frame

Primarily used for expansion or extension of a building, lean-to frames can provide additional space very economically.

They are commonly used to provide additional office or storage space for a larger building.

A lean-to frame typically has a single slope profile (no ridge) and straight sidewall columns (it must be supported by attachment to another frame).

multi-span framing system

Multi-Span Frame

Multi-span frames are commonly used for building layouts that permit interior columns. The spacing between columns can be consistent or varied to meet your requirements.

Large open floor spaces are accommodated by using the minimum number of columns which allows large open space and easy movement of fork lifts, etc.

These frames are most often used in manufacturing plants, warehouses, truck terminals, and retail stores.

Bracing Systems

Bracing transfers seismic and wind loads from endwalls and sidewalls to the foundation.


Rod bracing (also called X-bracing) is a tension-only bracing system. It may be located in the roof and walls of a building between frame members, transferring longitudinal forces to the foundation.


Cable bracing (like rod bracing) is a tension-only X-bracing system.

It is one of the most efficient ways to transfer longitudinal loads to the foundation in smaller low-rise buildings, however it has application limitations due to capacity constraints for buildings with mezzanines, cranes, or in high seismic areas.


When bracing must occur in locations where doors or other accessories would interfere with rod-bracing, a portal frame may be used.

A portal frame is comprised of two columns and a rafter made of built-up material and is attached to the web of the sidewall columns.


Flange braces are the structural members that attach purlins, girts, and eave struts to primary structural members (columns or rafters).

They are used to prevent the main frame from twisting or buckling laterally under the load.

Can also be very useful as an erection aid to align the purlins and eave struts for easier and lower cost roof installation.

Kodiak Thermal Insulation System for Walls and Roofs

Robertson Thermal System (RTS)

Accommodating up to 18″ of compressed insulation, RTS provides an effective thermal barrier for energy-efficient roof and wall construction.

RTS reduces heat loss through the envelope (compared to traditional metal building insulation systems) so that smaller heating/cooling units that consume less energy may be used, reducing initial and building operating costs.

Intended for both new and retrofit construction, cost-effective RTS is easily customized to provide the level of energy efficiency required for your building.
