How thick is a steel joist?

Standard depth = 2.5”. Deeper depths may be available from joist manufacturer.

Which type of open web joist is stronger?

Span further TRIFORCE® open joists are stronger than most solid joists and can fill the bill for a couple of reasons. First, they can span further to support an open floor space without intermediate bearing walls.

How far can a 2×6 metal joist span?

A 2×6 spaced 16 inches apart can span a maximum distance of 13 feet 5 inches when used as a rafter, 10 feet 9 inches when used as a joist, and 6 feet 11 inches when used as a deck beam to support joists with a 6-foot span.

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 AJ joist?

The ALLJOIST® series I-joists have solid-sawn eased edge flanges, proven web stock, and approved structural adhesives. These joists are designed to provide premium quality, high performance floor and roof systems that are priced competitively with traditional construction materials.

Why is a truss better than a beam?

The truss bridges are the strongest since they are able to withstand both the tensile and compressive loads, while all types of beam bridges rely mostly on the tensile loads. The truss bridges are generally used for the heavy loads that are determined by the truss bridge designs.

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 joist span?

A joist is supported at either end by either a beam, wall, or other framing member. They may also require additional supports, known as “intermediate supports,” along their length. Joist span is the distance between the beams, walls, or other structures that support a joist along its length. Joists are often made from wood or steel.

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.

What is a bar joist?

A bar joist is a structural component used to frame floors or roofs. The bar joist consists of a pair of parallel chords connected by a series of intersecting supports known as “webs.” Bar joists feature a similar design to trusses, including the same triangular web pattern, but are generally smaller and more lightweight than most trusses.
