Covering Systems

C.F. Maier has over 40 years of experience in the field of large-area covering systems made of glass fiber reinforced polyester resin. We offer numerous modular system variants, as well as special constructions.

Our company has manufactured large-area covering systems made of glass fiber reinforced polyester resin for technical buildings since 1978. One of the oldest C.F. Maier coverings has been in use at a German industrial chemical plant since 1979. Covering around 58,000 m², it is one of the largest of its kind in Europe.

Our protection and closure elements are suitable for applications such as tanks, silos, large containers, or conveyor systems.

The functions and dimensions of such covers do not allow for a standard design. But to ensure economical and cost efficiency, we offer numerous modular system variants of our products. Special constructions, such as non-round covers, are easily done. Over the years, many such innovative constructions have been created – some with very large spans.

As part of project management, we offer support in your selection of the right type, construction, static calculations and approving the building dimensions on site. Our experienced teams also takes care of the final installation on site.

All our containers have been styled by recognized designers and score points not only for their functionality, but also their looks.

Oekotub – space-saving container concept made of glass fiber reinforced polyester resin

In cities, space is a precious commodity – which made it all the more important to us to find a space-saving concept for recycling containers with an attractive design. Due to the practical disc shape, our Oekotub containers can easily be placed in a row at the collection point.
