Metal bar joists vary in depths and shapes therefore attaching the insulation to the bar joist building can prove to be limited in comparison to a common metal building.
Steel bar joist roof.
Steel joists handle loads and span conditions that a tradition wood system cannot typically handle.
Decking is made by forming and coating sheet steel.
These concentrated loads often include standard steel joists that are in turn supporting steel roof or floor deck.
It is installed above the joists to serve as a base of support for either a roof or a floor.
Therefore steel bar joists or also known as open web steel joists for framing floors and roofs offer many advantages when compared to a wood truss or steel beam system.
Bar joist buildings are often times insulated on the underside of the roof deck to increase the building s energy efficiency.
Joist girders serve as primary framing members with simple spans to support concentrated loads for a roof or floor system.
Typically used in non residential construction steel joists and joist girders provide an economical system for supporting floors and roofs.
Open web steel joists are an engineered truss like construction component used to support loads over short and long spans alike.
For floors concrete is typically poured over the decking.
