With Graepel-DuraVent, Graepel offers you an as yet unique symbiosis of a high-precision punching procedure and an effective anti-corrosion coating.
Your advantage: Corrosion protection for perforated metal sheets with 1000 h resistance in salt spray test.
The result: 7 % more air flow compared to traditional ventilation grilles.
Highly effective, durable, and from one reliable source: Your expert for perforated metal sheets, Graepel.
In a hitherto unique procedure developed by Graepel, we created an optimal combination of the punching and the coating process. Both steps of the process are carried out on-site at our company premises in Löningen. This leaves you independent of the cooperation of different contractors, which often happens to run suboptimally. You receive all the services for the production and finishing of your perforated metal sheets reliably and in first class quality from one source. Currently, it is only Graepel who offers you this combination of services.
From the start, we reduce corrosion phenomena drastically by using high-precision tools and a special coating procedure. In addition, this treatment allows us to significantly decrease the coating thickness.
Your advantage: Increase of the cooling air flow quantity with consistent structural capability.
Another positive effect: The airstream can enter the engine room with a significantly diminished deflection.
