Our Elements – WATER AND STAINLESS STEEL
Stainless steel has outstanding advantages for the construction of swimming pools.
A low maintenance and materials expenditure makes stainless steel less expensive than conventional building materials.
Long construction periods are a thing of the past as prefabricated individual segments are delivered and then installed on site.
The material can be easily processed at low temperatures so that a rehabilitation can be carried out out of season.
The smooth surface prevents the formation of algae and provides optimal hygienic conditions both inside and out.
The high elasticity of this material renders it almost insensitive to settlements and temperature fluctuations.
Stainless steel has for many years being increasing in importance and with its universal mol ability, it provides unrestricted possibilities in the language of forms.
Experience with this material has shown that it provides a long serviceable life without reducing its optical quality.
This means that stainless steel has the ideal requirements for swimming baths.
The industrial application of stainless steel started with the granting of a patent for “ steel with a high resistance to corrosion “ in 1912.
This was the starting point for the development of a group of materials containing more than 120 sorts of stainless steel which are used in all fields of human life, from the household to the building industry and the construction of swimming pools.
The past development is also mirrored in the production figures.
The annual crude steel production of non - corrosive steels increased from approx.12.8 million tonnes to around 18.4 million tonnes between 1990 and 2000.
All of the stainless steel sorts have a minimum chromium ( Cr ) content of 10.5% and have a greatly improved corrosion resistance when compared to non – alloyed steel.
The passive layer which acts as a barrier between the alloy and the surrounding media is responsible for this.
The passive layer is impermeable.
In case of damage, it automatically restores itself under the influence of oxygen.
Higher chromium contents and the addition of all alloy elements such as nickel Ni ), molybdenum ( Mo ) manganese ( Mn ) and copper ( Cu ) improve the corrosion, but can also alter the mechanical properties.
Due to its extraordinary range or properties, its durability and maintenance friendliness, stainless steel has a considerable added value potential.
The material is very often the optimal technical – commercial solution.
With a growing quality consciousness, it continuously grows in importance due to its likewise aesthetic possibilities and the same time opens up new market potentials.
In the course of time, manufacturers and processors have utilised various synonyms such as V2A or V4A.
Starting from the consumer sector however, the term stainless steel has asserted itself as a collective term.
Non corrosive steels are however designated with allocated material numbers such as 1.4404, 1.4571 or similar.
