The best “all around” solution
The Graeff Alpha hall is a true classic among the fast assembly halls: Unbeatable, when it is about creating the most marginal cost within a short time.
Many a time you bethink of the advantages of the circular roof shape. More and more planners are choosing the good and inexpensive solution. The steel frame construction is in volume production and can be transported extremely space-saving. The roof and wall cladding is available in several standard colours. It is made of galvanized corrugated iron that is coated with a long-life lacquering.
For the temporary use the Alpha hall can be mounted on square timber fundaments; on a permanent basis, however, we recommend a strip foundation. And the isolation? – The best isolation is achieved by using clecon sub-clamping. As a second possibility there is a thermal isolation, that consists of corrugated metal with rock wool inside it.
