Shortest Bar Joist

Shortest Bar Joist

Shortest Bar Joist

(OP)
What is the minimum span length barjoist manufacturable?
Thanks!

RE: Shortest Bar Joist

Tables for K-series start at 8 feet. Use joist substitutes, small beams, channels or tubes for 10 feet or less. Refer to Vulcraft joist catalog.

RE: Shortest Bar Joist

Look at using VS joists.

RE: Shortest Bar Joist

Use hot rolled steel sections. They might be more readily available from local warehouses/steel shops. If you have lots of steel joists on the projects, them use VS joists as suggested above.

RE: Shortest Bar Joist

Another alternative, depending on loading, is cold-rolled steel sections - C and Z light gauge purlins.  They are lighter than the standard roll sections, therefore easier to handle in the field.  You do have to be more careful with lateral bracing and connections.  Just a thought!

RE: Shortest Bar Joist

Make sure you proceed with caution when using VS joists depending on the fire rating required if applicable. VS joists at this time are not U.L. rated.
