With design elements in stainless steel look and glass

Due to their size, garage doors shape the overall impression of a house. That is why the appearance is particularly important here. We help you to develop customised solutions in aluminium or wood for your customers.

Every garage door is unique!

For decades, we have been manufacturing standard doors and exclusive lines for the Austrian market leaders in this sector, which are also matched to the range of facing panels for front doors. This results in a coherent overall offer.

Included design elements in stainless steel look (combined with or without glass) support modern architectural concepts. We prepare these in the way that best fits your production process.

We would also be happy to support you in taking up garage doors in standard configuration or completely individually.

Individual one-off pieces – Krotzer makes it possible!

We are able to respond completely flexibly to your customers’ ideas and include initials, house numbers, house names or personal symbols that identify the house owners in the garage door design. There are no limits to your imagination.
