The BALU brand stands for innovation, high-quality treatment, successful design and optimum production, in consideration of all safety criteria. The high-speed folding gates of the QUATTRO Premium series & QUATTRO ECO from BALU stand out due to their high functionality, efficiency and opening speed. They are the safe replacement for classic sliding gate / barrier system combinations that only allow traffic control but do not provide security against unauthorized entry. These gates are predestined for driveways with limited space on both sides and a small slewing range. The design of the specially developed aluminium profiles is the basis of these gates in addition to the high-quality treatment. With a maximum opening and closing speed of up to 1 m / sec and their space-saving design, the high-speed folding doors live up to their title. The gates are designed with 100% duty cycle for continuous operation. The BALU QUATTRO models are already preinstalled and tested at the factory. This makes assembly and connection easier on site and minimizes assembly times and possible assembly errors.
