## What is joist depth?

Standard depth = 2.5”. Deeper depths may be available from joist manufacturer. Joist Substitutes standard depths are 2.5 inches and may have extended ends for overhangs (outriggers). “Double” joist substitutes can be used to obtain capacities other than those in the Load Table, or the spacing can be varied.

How far can a bar joist span?

These members have been standardized for depths from 20 inches (508 mm) to 120 inches (3048 mm), and spans to 120 feet (36,576 mm). The standard depth at the bearing ends has been established at 7 1/2 inches (191 mm) for all Joist Girders.

What’s the difference between a joist and a truss?

The joist supports the load which the floor is built to bear. A truss is used to support the roof.

### Are trusses stronger than joists?

Span longer distances than traditional joists, removing the need for walls in some areas. Lighter weight. Stronger than traditional joists. Wider nailing surface (making the building process easier)

### What are the dimensions of a K series joist?

These joists easily handle spans that wood systems cannot handle while their lightweight construction makes them much less costly than steel beams. K Series joists range in depth from 10” to 30” and can span up to 60’.

What are the dimensions of LH Series Joists?

These joists easily handle spans that other systems cannot handle while their lightweight construction makes them less costly than crustal steel beams. LH Series joists range in depth from 18” to 48” and can span up to 96’-0″.

How to calculate the joist total load deflect?

W (TL) = from Joist Standard Load Table deflection of 1/360 of span (plf). The Deflection Ratio = Req’d. W (LL) / Allow. W (LL). where: Req’d. W (LL) = w (LL)*S Allow. W (LL) = from Joist Standard Load Table Deflect. Total Load Deflect. Live Load Deflect. ?? Determine Equivalent Unif. Dead and Live Loads w (TL) ?? Unif. Dead Load, w (DL) =

#### How big does a steel joist need to be?

Joists, girders, and bridging are available in prime painted gray finish, uncoated, or galvanized. Joists and girders are available in one-piece design up to 120′-0″ before field bolted splicing would be required. 2.5″ Deep: 2.5JS1, 2.5JS2, 2.5K1, 2.5JS3, 2.5JS4, 2.5K2, 2.5JS5, 2.5JS6, 2.5K3, 2.5JS7
