About Dan-How

Reputable perforation specialist

At Dan-How Perforation ApS, we have experience with microperforation of pre-coated steel and aluminum since 1978.

In recent years, we have expanded our expertise with perforations in plastic and stainless steel. Our production is modern, automated and based on continuous perforation of coils with self-designed tools.

Our tools are simple and thus flexible. This means that our tooling costs are financially competitive, we can offer short delivery times, and almost all perforation requests can be met.

HAUFE-Deckensysteme GmbH-Tyskland
Als Hersteller von Deckensystemen arbeiten wir seit gut 10 Jahren mit der Firma Dan-How eng zusammen,
die für uns die Bänder unserer Lamellendecken mikroperforiert. Um die Qualität unserer Systeme auf einem
gleichbleibenden hohen Niveau zu halten ist es für uns wichtig, dass der vereinbarte Qualitätsanspruch an
Lochung und Richtqualität verbindlich eingehalten wird. Ebenso müssen wir durch die Objektarbeit Liefertermine
verbindlich einhalten und oft auch sehr kurzfristige Lieferungen realisieren. Die Firma Dan How hat uns hier immer
voll unterstützt und stehts pünktlich die geforderte Qualität geliefert. Wir schätzen diese Zuverlässigkeit und die
immer freundliche Zusammenarbeit, auf die wir hoffentlich auch zukünftig setzen können. Herzlichen Dank
vom gesamten Team der HAUFE Deckensysteme GmbH.
