K-Series joists are designed for use typically with lighter loads and are most common in roof design. Typically where shorter span conditions are required.

KCS-Series Joists are a version of the K-series joists, but designed for a constant shear and moment, which allows for greater flexibility for locating extra loads such as those from rooftop units.

LH-Series Joists are for longer span conditions and are capable of supporting larger loads. These joists allow for special profiles to accommodate a variety of conditions. Some of the typical special profiles include gable joists and arched joists.

As with LH-Series joists, DLH-Series (Deep Longspan) joists are for longer span conditions and support larger loads. With standardized depths from 52” through 120” and spans up through 240 feet, DLH joists also allow for special profiles to accommodate a variety of conditions.

Joist girders are primary framing members. The design is simple span, supporting equally spaced concentrated loads from open web steel joists. Joist girders are designed to allow for the efficient use of steel in longer spans for primary framing members.
