Steel Joist Roof System

Our joists and girders are engineered and manufactured in accordance with the specifications of the steel joist institute.

Steel joist roof 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. 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. Spantec systems are designers and manufacturers of boxspan steel flooring systems. The proprietary design allows totaljoist to be installed similar to wood i joists.

Joists are often doubled or tripled placed side by side where conditions warrant such as where wall partitions require support. We make joists bearers rafters verandah beams plus piers and bracing. From steel joists and deck to long span composite floor systems we engineer and manufacture solutions that control costs enhance performance and ensure project success. Depending on loads and spans c joists are typically spaced at 12 16 19 2 or 24 on center spacing.

Standard steel joists and joist girders are crucial tried and true components of your roofing and flooring building system. Joist girders are open web steel trusses used as primary framing members. Open web steel joists are an engineered truss like construction component used to support loads over short and long spans alike. These concentrated loads are considered to act at the panel points of the joist girders.

Structural track usually in the same gauge as the joist is used as rim or band enclosures. Together let s build it better. Tradeready steel joists are precision manufactured from corrosion resistant galvanized steel. 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.

Joist to girder attachments are normally supported with joist hangers easyclip e series or s series support clips. We have the expertise to help you determine the optimal structural steel building system for your application. The joist also features a series of smaller holes for electrical and technology lines. Typically used in non residential construction steel joists and joist girders provide an economical system for supporting floors and roofs.
