Steel joists are key components to your roofing and flooring system. New Millennium engineers and manufactures a full range of standard steel joists (also known as bar joists) plus composite joists (CJ-Series) and Joist Girders. We can provide early design assistance for total-project cost optimization, including load zone joist design. All joists are locally available, and manufactured in accordance with the specifications of the Steel Joist Institute.
Steel joist products include K, LH and DLH Series joists, designed and manufactured in accordance with the specifications of the Steel Joist Institute. Single piece joists can be produced up to 120 feet long, with field splices used to increase lengths and depths. Available with either under-slung or square ends.
A composite joist (CJ-Series) is a steel joist designed for shear connection to the overlying concrete slab using field applied shear studs, such that when the decking is filled with concrete, the shear studs become embedded in the hardened concrete and a unified load bearing system is created that deflects as a single unit.
An alternative to specifying KCS series joists is to specify joists designated as KZ to support the concentrated loads residing in specific areas defined as “load zones”. With the boundaries of the zones defined and the corresponding concentrated loads specified, New Millennium can substantially engineer steel material costs out of a project.
Joist Girders are open web steel trusses that serve as primary framing members. They are designed as simple spans to support concentrated loads for a floor or roof system. These concentrated loads are normally considered to act at the top chord panel points of the Joist Girders.
