Our company takes responsibility for the sustainable, environmentally friendly use of materials. Efficient production processes and optimized tool procedures support us in our aim of using resources reasonably and effectively. Metal serves as the basis for all our work and, being a sustainable raw material, can be perfectly integrated into the high demands of our production processes.

RIB-ROOF metal roof systems not only impress by their timeless design, but also by their long lasting durability and practicability. Since metal hardly wears out when processed, the RIB-ROOF roof is as impressive in its application now as it was in the past.


Our RIB-ROOF metal roof systems stand for high efficiency and safety, fulfill all requirements of sustainable construction methods and have the European Technical Assessment (ETA) as metal roof for all single-deck and multiple-deck roof constructions. Furthermore, various environmental product declarations are available for our products.

Our products are listed in the DGNB Navigator:


Our products are designed to last a lifetime. In addition, all non-ferrous and light metals have a positive eco-balance. We are constantly optimizing our production processes and techniques in order to save electricity and water and reduce environmentally harmful emissions. We have been actively involved in the Environmental Pact Bavaria since the start of the initiative. It therefore goes without saying that our environmental management is certified according to DIN ISO 14001:2005. We received the Bavarian State Medal for Environmental Protection back in 2004.


Zambelli manufactures products strictly according to the national and international standards and technical regulations. Our quality management is certified according to DIN ISO 9001:2015. All our materials and products go through a strict internal inspection system. You can count on our products.


Our employees have contributed significantly to our success through their constant commitment and productive performance - since the very first day. A respectful relationship based on trust is a basic requirement for us and a prerequisite to be able to “build bridges” and strengthen the family business.
Thus, it is of utmost importance for us to establish family-friendly policies in the long term. Therefore, we are part of the Bavarian initiative “Family Pact Bavaria”.

The Zambelli Group is a constantly growing family business that offers its employees a large family with over 1,200 staff members.
