Weather protection grid – with slat crossbar and spring – galv.

Custom-manufacturing and permanently installing steel weather protection grilles

This kit, featuring a slat bar and spring, is made from galvanized steel. It offers a flexible and cost-effective solution for the in-house manufacture of weather protection grilles for air duct construction. The particular advantage of this system lies in the combination of the slat bar and retaining spring. The louvres are securely positioned and reliably fixed, whilst custom dimensions can be achieved without the need for complex bespoke manufacturing. The louvre spacing of 68 mm ensures a tried-and-tested design for supply and extract air ducting.

In practice, air duct manufacturers, building services contractors and fitters regularly face the challenge of adapting weather protection grilles to project-specific opening dimensions. Prefabricated standard solutions result in longer delivery times or additional procurement effort. With this steel weather protection grille, you can manufacture precisely fitting solutions directly in your own production facility. The fixed slats help to protect fresh air and exhaust air openings from the elements. When used in conjunction with a bird guard, the ingress of leaves, small animals and debris can be reduced. The aerodynamically arranged slats ensure trouble-free operation of ventilation systems.
