How far can steel joists span?
deep joist has a maximum Span = 40 ft. between panel points from uniform loads.
How far can open web joists span?
120 feet
These members have been standardized for depths from 20 inches (508 mm) to 120 inches (3048 mm), and spans to 120 feet (36,576 mm). The standard depth at the bearing ends has been established at 7 1/2 inches (191 mm) for all Joist Girders.
What is steel joist framing?
Steel joist framing provides an efficient framing system for supporting floors and ceilings in a wide variety of building types. Since steel joists are lighter than wooden trusses, the size of the supporting structural elements as well as the size of the building’s foundation can be reduced for cost efficiency.
What are the webs of Open joist Triforce made of?
TRIFORCE® open joists are manufactured with an OSB panel at one end. This end of the joist may be trimmed up to 24″ to achieve the desired joist length for installation.
What are the 6 different types of floor joists?

What is K series joist?
K-Series. K-Series joists are designed for use typically with lighter loads and are most common in roof design. K-Series Joists are used typically where shorter span conditions are required.
What is the standard floor joist spacing?
16 inches apart
Most often, floor joist spacing is 16 inches apart on center, but this can vary depending on building codes and the requirements of the structure in the blueprint. Floor joists help distribute the load of a structure.
What is an open web truss?
Open-Web Trusses. Since its introduction in 1960, the open-web truss has become one of the most widely used engineered wood building products in commercial construction. Open-web trusses are lightweight, easy to install, and have nailable chords for easy attachment of roof decking and ceiling materials.
What is a joist beam for an opening?
A joist is a horizontal structural member used in framing to span an open space, often between beams that subsequently transfer loads to vertical members. When incorporated into a floor framing system, joists serve to provide stiffness to the subfloor sheathing, allowing it to function as a horizontal diaphragm.
What is steel joist?
In structural engineering, the open web steel joist (OWSJ) is a lightweight steel truss consisting, in the standard form, of parallel chords and a triangulated web system, proportioned to span between bearing points.
What is a joist girder?
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.
