In Company A&T Europe SPA, for which I from 2004 to 2013 worked, pools are made of coated stainless steel sheets. In fun pools, which have a large market share in Germany, more and more large water slides are desired. Safer than the previous “drop in the pool” is a construction, which can slide the guests in the water. The technology of A&T Europe Spa prefers only a (not behind desinfected, used) slide end from GRP. Of own material no outlet had previously been constructed with double rounding. The construction of such slide end from own material was to 50% cheaper than the purchase.
