special colours are also available. For tropical climatic conditions special fabric qualities are available. The assembling of the individual material strips into complete tailor- made air supported structure, is mainly carried out by high frequency welding. This is proved to be a most successful method. An alternative to welding is the stitched and seamed joint, this also is very stable in the construction of an air supported structure. Production according to official specifications. Material and production are liable to permanent supervision through official test authorities. That is: guarantee for constant, high quality and many years of know how through continual production.
