What is Global Truss?
Global Truss is one of the two or three aluminum truss systems you will find on almost every stage, trade show floor and mobile DJ rig in the United States. Its F-series uses conical connectors, a tapered pin-and-socket joint that pulls two segments tight into a single continuous run, and that connector is what makes the system modular: any F34 segment mates to any other F34 segment regardless of length. Hollywood DJ carries 629 Global Truss line items.
F31, F32 and F34: what is the difference?
In a Global Truss series name, the first digit stands for the profile size and the second digit is the number of chords, meaning load-bearing tubes. The F3x profile is 11.42 in (290 mm): F32 is a two-chord ladder, F33 a three-chord triangle and F34 a four-chord square box. F31 is a single 1.97 in (50 mm) tube. More chords means a stiffer truss that carries more over a longer span, and also more weight and more money.
| Series | Chords | Profile | Typically used for | Lengths we carry |
|---|---|---|---|---|
| F31 | 1 | Single round tube | Short light bars, decorative arcs, drape and signage support | 1.64 to 9.84 ft, single tubes |
| F32 | 2 | I-beam, flat ladder | Straight runs of fixtures, backdrops, wall washes | 0.95 to 14.76 ft |
| F34 | 4 | Square box | Goalposts, roof grids, any span carrying real fixture weight | 0.95 to 13.12 ft |
All three use 2 mm wall tube and conical connectors in the segments we carry, apart from one heavy-duty 3 mm F34 piece, the SQ-4112-275P. F34 is the default choice for anything structural. F32 saves weight on a straight fixture run. F31 is for light decorative work, not for hanging a rig.
How much weight can Global Truss hold?
There is no single number, and you should be suspicious of any retailer who gives you one. Working load depends on the span between supports, whether the load is a point load or spread evenly, how the truss is supported, and the specific part number. Global Truss publishes engineer-stamped load span tables for most of its square and I-beam series, and where a stamped table exists that table is the figure to rig from. Some series, including F31 single tube, have no stamped table at all. A qualified engineer or professional rigger should plan and approve any truss or staging installation. We are happy to talk through a configuration on the phone at 1-800-700-4542. Ask us and we will send you the stamped load sheet for your part number, or tell you plainly that there isn't one, rather than guess.
Where can I get Global Truss load span tables?
Right here: we host Global Truss's own load span tables on our site, each exactly as Global Truss published it, so you can read the sheet for your series before you order. Each sheet rates only the Global Truss series it names.

Can I mix Global Truss with ProX or Show Solutions?
Within the same series, these brands are built to the same conical interface and are widely used together in the field. That said, mixing brands in one structural span is a decision to make deliberately: tolerances, wall thickness and hardware can differ, and a manufacturer's load table applies to its own product. For a loaded goalpost or anything overhead, stay in one brand and one series, because a load table covers only its own manufacturer's product.
Does truss ship freight, and do you have it in Los Angeles?
Most truss ships LTL freight rather than parcel, because segments are long and the packaging is oversized. Freight needs a quote and a delivery appointment, so call us and we will price it with the order. Most Global Truss items are not in our Los Angeles warehouse: they ship directly from Global Truss, so they do not qualify for our same-day shipping, and ship times vary by item. If you need truss by a show date, or want to pick up in Los Angeles, call 1-800-700-4542 before you order to check timing.
