Steel Joist Roof System

Joist girders are open web steel trusses used as primary framing members.

Steel joist roof system.

Spantec systems are designers and manufacturers of boxspan steel flooring systems. Together let s build it better. The main use of an owsj is to provide support for roof or floor deck and to transfer the load imposed on the deck to the structural frames beam and column. Standard steel joists and joist girders are crucial tried and true components of your roofing and flooring building system.

When incorporated into a floor framing system joists serve to provide stiffness to the subfloor sheathing allowing it to function as a horizontal diaphragm. These concentrated loads are considered to act at the panel points of the joist girders. Open web steel joists are an engineered truss like construction component used to support loads over short and long spans alike. They are designed as simple spans supporting equally spaced concentrated loads for a floor or roof system.

Joist to girder attachments are normally supported with joist hangers easyclip e series or s series support clips. 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. The proprietary design allows totaljoist to be installed similar to wood i joists. Typically used in non residential construction steel joists and joist girders provide an economical system for supporting floors and roofs.

Structural track usually in the same gauge as the joist is used as rim or band enclosures. Steel joists offer consistent quality predictable performance and high strength to weight ratio and they are dimensionally stable. The joist also features a series of smaller holes for electrical and technology lines. We have the expertise to help you determine the optimal structural steel building system for your application.

Depending on loads and spans c joists are typically spaced at 12 16 19 2 or 24 on center spacing. Joists are often doubled or tripled placed side by side where conditions warrant such as where wall partitions require support. Our joists and girders are engineered and manufactured in accordance with the specifications of the steel joist institute. Totaljoist is an easy to install cold formed steel floor joist that offers a robust simplified framing solution compared to traditional wood or steel joists.
