Global Truss F34: parts, chart criteria and rigging limits

Identify Global Truss America F34, its supplied pins and the correct load-chart case before treating a layout as a structural design.

Identify the truss

Ask GLMedia about rental options for your event. The proposal is subject to availability, confirmation of the model and configuration, and the venue’s technical requirements.

F34 is a square aluminum truss family from Global Truss America. This guide covers straight sections with the documented conical connection. It does not establish compatibility with Eurotruss FD34, another brand or a different Global Truss family.

Section and connection references

Example section: SQ-4111: 1.5 m overall length and 290 mm overall width. Identify each actual section separately.
Published tube dimensions: Main chords: 50 × 2 mm; diagonals: 20 × 2 mm.
Connection: Conical coupler, tapered pin and safety clip. The official F34 sheet requires pins supplied by Global Truss.

The official sheet separates strength with L/180 deflection limits, strength-only data and reduced loading under its stated standard. These are different criteria. Have the structural designer identify the applicable case rather than choosing the largest value. The table’s loads are not additive and dynamic or shock forces are not included.

Parts and supporting documents

Specify section references, genuine connection parts, supports and attachment positions on a rigging plot. A floor-standing arch also requires bases and an approved stability design; a drawing tool that lists dimensions does not determine ballast or load capacity.

Prepare the configuration

Record all component references, labels, lengths and inspection status. Keep unidentified mixed hardware out of the assembly until its identity and compatibility are documented.
With unloaded components safely accessible, note damaged chords, welds, connection holes and missing clips. Do not force a misaligned joint or alter a pin or hole to make it fit.
Compare actual support and load positions with the F34 engineering sheet. It requires loads at panel points and review of rigging plots by a licensed structural engineer; bridles need that engineer’s written approval.

Three technical questions

A similar-brand conical connector fits. Does that make it compatible?
The planning tool shows a goalpost. Does the beam table prove it is stable?
Can I add the center-point and distributed-load allowances?

A similar-brand conical connector fits. Does that make it compatible?

No. Compare manufacturer, family and connector/pin/clip references with the documented parts list. Physical fit and visual similarity are not documented compatibility. Do not use an unidentified substitute to complete a connection; resolve it with the responsible supplier before loading.

The planning tool shows a goalpost. Does the beam table prove it is stable?

No. Record the complete geometry, bases, supports, attached surfaces and intended loads for review. A horizontal span table does not define column capacity, corner behavior, overturning resistance or wind limits. Keep the proposal out of use until the complete configuration has its required design; no universal base-plate weight or ballast quantity follows from the drawing.

Can I add the center-point and distributed-load allowances?

No. The official notes explicitly say the tabulated loads are not additive. Identify the actual combined load positions and get the applicable assessment. Truss self-weight is already included in the published data, so do not deduct it again or use that fact to add an extra load allowance. Confirm the chosen table criterion as well as the span.

Limits before installation

Use the documentation for the actual F34 system. A manual for a separate packaged TRUSS/SYSTEM kit does not establish this assembly’s operating limits. Do not use the engineering drawing to fabricate or repair parts, suspend from an unapproved point or change connections under load.
