QUADROSYSTEM manufactured by the LUMEX Company forms a stable construction system that has all the advantages of the TRISYSTEMU and enhanced strength.

Such elements are used in contructing structures with long horizontal beams and those where extra load has been envisaged.

Such elements are used in contructing structures with long horizontal beams and those where extra load has been envisaged. Thanks to high load-bearing properties, the system is used in constructing structures intended for mass events. The QUADROSYSTEM is manufactured in to variants, differing in spacing the longitudinal tubes and the construction of the end connector. In case of the first one, the symmetry axis are situated at the corners of a square of 240 mm sides and the tubes have walls either 2 or 3 mm thick and are end-joined with a dye cast frame. They can be assembled into beams 10.5 m in length. In case of the second one, the axis spacing between the tubes is 350 mm, the wall is 2 mm thick and the ending is welded out of components. Using these elements, up to 14 m long beams can be constructed.

The assortment of the QUADROSYSTEM is supplemented with QUADRO PAR 64as well as with a system of trolleys and hoists permmiting the assembly of a stage roof including its lighting at ground level and then hoisting it at the desired height, Thanks to such assembly design, only four people equipped with basic tools are needed to assembly a large stage.
