Truss floor deck that stays in place, and mezzanines built on it<\/h1>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Our deck combines a steel bar truss with a fibre-reinforced base board that bonds to the slab. No formwork to strip, no plaster underneath. The questions buyers ask are about props, joints and approval, so this page answers those.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t

What decides a good pour<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tProps.<\/b> The deck carries wet concrete and workers between supports during the pour. Above about 2 m clear span, or for thick slabs, add a line of props. The deck table gives the limit per model.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tJoints.<\/b> Butt joints must be tight and supported so grout does not leak. Damaged boards are replaced, not patched.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tTruss welds.<\/b> Check the bar truss weld points and bar spacing on delivery; loose welds are rejected.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tServices.<\/b> Conduits run through the truss zone before the pour; holes cut later damage the board.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
