Bar joist questions.

Have a project in Texas or the Southeast?

What are bar joists?

Bar joists are open web steel joists: a top chord and a bottom chord connected by a zigzag web, used to support roofs and floors. We fabricate them at our own joist plant.

What is a joist girder?

A joist girder is a heavier open web girder that carries the steel joists and transfers their loads to the columns. We fabricate joist girders with the joists.

Are you steel joist manufacturers or suppliers?

Both. We manufacture steel joists and joist girders at our dedicated joist plant in Ciudad Juarez, Mexico, with 500 tons a month of capacity, and supply them to US projects.

How far can steel joists span?

Steel joist span depends on the loads and the design. We engineer and detail each joist for your project.

Can I order joists without the full structure?

Yes, when the volume fills whole trucks. Joists also ship with the structural steel and roof deck as one package.

How fast can you deliver?

2 to 4 weeks from approved drawings to your site.

Do you build to US codes?

Yes. We comply with US codes and standards.
