Sleeker profiles, lighter slabs


Tray-dec NZ Ltd recently launched two new composite steel flooring system profiles, the Ultra Span 80 and Concrete Saver 60.


The company’s Traydec 300 product has been on the market for 32 years and is a popular flooring system for multi-storey apartments.


Tray-dec manager Grant Hjorth says with the newcomers the company’s products have become more specialised.


“Traydec 300 remains the best in its market niche, but these products are the latest generation in hi-tech composite steel decking that allows for shallower and longer spans.


“Both products were designed to use up to 4% less concrete for a given slab thickness than other profiles on the market, resulting in substantial cost savings for the builder,” Mr Hjorth says.


“Also, because this steel deck has no extra height due to profile intrusions, the required slab thickness to control shrinkage cracking is less, resulting in lighter slabs,” he says.


Ultra Span 80 is an 80mm-high trapezoidal profile manufactured in grade 500 high tensile galvanised sheets. Concrete Saver 60 is a 60mm-high trapezoidal profile with, compared to other profiles, reduced pan width.


Both products can be ordered in standard thickness and sheet lengths up to 12 metres, although the company can accommodate special requests for longer sheets.


Both products comply with design and construction standard BS5950 and fire standard NZS476.


Mr Hjorth says the new products enter the market with a competitive advantage — Traydec 300’s good reputation.


“The University of Canterbury’s independent tests four years ago proved Traydec 300 has the best acoustic and fire rating of its product type in the country. With Concrete Saver 60 and Ultra Span 80’s additional built-in quality and cost-saving characteristics, we have two more winners.”


Tray-dec moved to new premises in Avondale, Auckland, in late 2006. Traydec 300, Ultra Span 80, Concrete Saver 60 and custom folded edging for both are available directly from Tray-dec and all major building supply merchants. Tray-dec can also arrange installation nationwide.
