9 – flange width in cm, (88 mm)

08, 10, 12 – steel web thickness 0.8, 1.0, 1.2 mm respectively

For residential, Tecbeam joists can span up to 7.4m, please refer to the span tables here for the range of spans and spacings for various loads

T25: 156mm

T30: 212mm

Yes, these are available as an AutoCAD patch or in PDF, please refer to the Details section in the web site here

Yes, our span tables show loads for 3, 4 & 5 kPa; if required, TECBEAM joists can be designed for floor loads exceeding 15 kPa. Please refer to an Engineer or Tecbeam Australasia for floor loads greater than 5 kPa.

Yes, this is one of the outstanding features of Tecbeam joists due to their inherent strength and low creep factor.

Yes, the steel web provides continuous support to the flanges and strongbacks can be used to share the load with adjacent joists, this feature often eliminates steel beams.

For Tecbeam joists the creep factor is 1.4, whereas all timber it is 2.0, a 60% reduction using Tecbeams! This can eliminate excessive deflections over time and  save on maintenance.

No, they can be cut to any length. When cut install a pair of web stiffeners at the end, nailing through the steel web; if the cut is at a web hole place an extra pair of web stiffeners alongside so that at least eight nails pass through the steel web.

For Tecbeam joists floor vibration is easily controlled using strongbacks, if you want an even more solid feeling floor, simply add another row of strongbacks or use a section with higher stiffness, eg LVL. There is no need to specify the next size joist.

Yes, but proper weather protection will be needed. Joists with treated timber flanges and galvanized nails can be supplied, the web has a zinc coating of 275 gm/m2, a good paint system is recommended, plus flashing over the top flange in open decks. Periodical maintenance inspections are recommended for important structures.

Yes, joists with timber flanges treated for termite protection can be supplied.

Yes in long spans, strongbacks are used instead of installing time consuming solid blocks; the wide flanges enable strongback spacings to match those used for floor vibration control. No additional strongbacks are required.

Yes, they certainly can, long spans are achievable and bracing is simple using strongbacks. Tecbeam joists can be a very economical solution in large commercial and industrial roofs.

Tecbeam joists have a high load carrying capacity and when linked together with strongbacks the combined load capacity often eliminates a steel beam.

In a combined system with a fire rated ceiling, the joists provide the structural support. Tecbeam joists in combination with a fire rated ceiling have been fire tested by the CSIRO and were approved for 60/60/60 and 90/90/90 FRLs. Higher ratings are feasible, these will depend on the ceiling construction. An alternative fire protection method would be to apply a fire protective spray coating.
