Leverkusen, Germany - Stage builders' back, a condition developed by lifting heavy stage sections into place, may be eliminated by lightweight stage sections developed by Dutch company Triple-E Lichtgewicht Meubilair BV in Winsum.
Each of the company's stackable, compact 0.75 x 1.50 m Flax-Deck sections weighs only 16.5 kg, but the sandwich structure can withstand a concentrated load of up to 150 kg. This light but extremely strong structure results from a composite sandwich method based on the Baypreg polyurethane spray system from Bayer MaterialScience.
For the highly versatile stage sections, Triple-E made a light, rigid foam core reinforced top and bottom with flax mats to absorb tensile forces.
Additional features are a highly abrasion-resistant and robust protective plastic cover in various colours and foldaway, height-adjustable aluminium legs.
To make the sections, Triple-E first impregnates natural flax mats on both sides with the dual-component polyurethane system, using a spray process. An expanded polystyrene (EPS) core is sandwiched between these mats and put in a preheated mould, at 60° to 120ºC and pressures between 6 and 8 bar.
