Questions from our project planners delight us. So here's a selection of answers to frequency asked questions - these are not always of a technical nature!
Stainless steel contains different proportions of nickel depending on the grade. Swimming guests coming into contact with stainless steel pools and experiencing an allergic reaction can rest at ease: Other than with components with a nickel content worn directly on the body, touching the stainless steel surface of swimming pools does not mean direct contact with nickel, the passive layer - the layer on the surface that makes the steel stainless steel - consists primarily of chrome oxide. The contact of the swimmer with the stainless steel surface does not result in any wearing off of the nickel.
The value of stainless steel at the end of the "life cycle" is based on the prices on the stock market. Supply and demand determine the price achieved on any given day. Because stainless steel is both a construction material and a very valuable raw material, the market volume is rising continually. The trend is continuing - stainless steel is a "material for generations" - because once produced, that stainless steel is re-used by future generations. Sustainability in its is finest form!
The colour of the water appears blue. Water filters out all spectral colours, except for blue. Depending on the water depth, purity and light refraction, the water surface in a stainless steel pool appears blue. With increased water depth, the blue becomes more intensive and darker.
Tiled, polyester and PVC pools generate an unnatural blue water appearance with the blue colour. This means that impurities in the water are virtually unnoticeable.
