For: F42, F43, F44
Trusses · 2-point
The F42 is the largest BÜTEC 2-point truss: 400 mm profile, 50 mm chord tubes, segments up to 5 m. It spans medium distances and combines with the F43 and F44 systems. Its load table covers 3 to 14 m.
Benefits
Its own load table for spans of 3 to 14 m, prepared taking DIN EN 13814 (temporary structures) into account. Structural calculations available, tested to Eurocode 9.
Conical connectors, truss pins and spring cotters for the F4x size class; according to the catalogue, the conical euro connection is compatible with various systems from other manufacturers.
The F42 combines with the F43 and F44 systems; the F4x connectors and spacers fit all three.
Special lengths and shapes from our own welding shop; powder coating in RAL colours possible.
Technical data
Permitted loads: see load table and data sheet. Outer sizes as stated in the data sheet.
Load table
Values from the F42 data sheet: permitted uniformly distributed load, centre point load and third-point load per span, each with deflection. The current data sheet is binding. For your specific construction we prepare structural calculations on request.

That is in the load table above and in the data sheet: for spans of 3 to 14 m, the permitted uniformly distributed load, the centre point load and the third-point load, each with deflection. For your specific construction with load points, suspension or towers, we prepare structural calculations on request.
The F42 is joined with a conical euro connection. According to the BÜTEC catalogue, this connection is compatible with various systems from other manufacturers; bolted connections are also possible. Tell us the maker and type of your stock and we will check the fit.
Yes, according to the manufacturer the F42 combines with the F43 and F44 systems. Connectors and spacers exist for the whole F4x size class (F42, F43, F44).
Tell us spans, loads and layout. We put together lengths, corners and accessories for the F42 and prepare a quote – with structural calculations if you need them.
