The TECBEAM "I" Beam Joist is a unique composite structural beam. The web consists of a continuous, light gauge galvanised steel plate, with stamped out stiffening ribs and regularly spaced service holes. Flanges of plantation-grown structural softwood are fixed (nailed) to this continuous steel web to form a composite "I" beam. TECBEAM joists demonstrate many superior performance characteristics when compared to other commonly used joists. Utilising the unique properties of our core product complete structural floor and roof systems have been developed. When the beams are utilized into a floor or roof system, TECBEAM joists can provide significant savings on the total cost of construction. TECBEAM joists can often replace heavy structural steel beams, so that no special cranage and handling systems or expensive welding or cutting are required on site. Ceiling plaster and flooring materials can be fitted directly to TECBEAM'S integral timber flanges, and most services are able to pass through its service apertures, including air conditioning ducts and large waste pipes, without weakening the beam or the need for special cutting. TECBEAM BENEFITS Some of the many benefits of using TECBEAM joists: Economic Significant savings in overall construction project costs. Ultimate user comfort and confidence Utilizing TECBEAM's very rigid joists and unique strongback system provides total control over vibration and guarantees every floor feels "solid" and has minimal "bounce" under live loads. TECslab© floors produce the ultimate in solid-feel lightweight floor structures by combining TECBEAM joists with aerated concrete flooring panels or a solid concrete topping. Higher Safety Margins if overloaded TECBEAM joists are not subject to catastrophic collapse during high overloading and are exceptionally ductile, so provide large safety margins for high load applications (such as storage areas); they are eminently suitable for constructions in earthquake and cyclone-prone areas. Flexibility in design Provides long spans between supports for relatively shallow floor depths Enables cantilevered balconies to be easily constructed using web holes Easy to replace unwanted bulkheads by running support beams internally Can be notched out at the ends to fit easily into steel support beams Can be angle cut at the ends to allow for sloping lower roof-lines. Saving on Steelwork With the capacity to support load bearing walls, point loads and upper floor set backs, due to TECBEAM's strength, stiffness and low creep factor. Easy installation of services Through TECBEAM's wide aperture holes, which are larger and more frequent than in many competing products. Environmentally friendly TECBEAM joists are constructed from 100% recyclable galvanised steel and small section plantation grown softwoods and replace deep section solid timber joists traditionally sourced from old growth native hardwoods or imported Oregon. Ease of use on site Rugged and easy to handle on site, relatively lightweight, with no special fixings/welding or cranage; supplied made-to-measure and able to be cut anywhere. Fast order fulfilment With a wide range of standard lengths kept in stock and able to be cut-to-length and delivered quickly, normally 24/48 hours turnaround for house lots.
