Stainless steel can also be used for the public lighting. In fact, the light poles must be resistant to moisture, to the weather conditions and to the thermal shocks. The choice of materiali is fundamental.
UNI EN 40 standards. What does it say?
There are specific requirements for the design and the construction of lighting columns. In fact, the UNI EN 40 standards specific what type of material must be used for the construction of urban lighting poles.
And beyond that, it shall also indicate some warnings to apply during the production of poles in order to protect them from corrosion. UNI En 40-5 standard, specifically, deal with all the specifications about stainless steel lighting columns.
Some characteristics
What are the characteristics which must take the lighting poles? It is fundamental which must not alter the environmental context. Moreover, must:
- Be resistant to the wind load and mechanical stress
- Be resistant to corrosion
- Basic maintenance
- Maintain adequate watertight integrity.
The importance of materials
What is the most used material for the construction of lighting poles? This is indeed stainless steel that is followed by fiberglass, aluminium and wood. What are the pros and cons?
FIBERGLASS
- PROS: allowing to make light poles (more safe in case of an accident)
- CONS: largest size of poles diameter
ALUMINIUM
- PROS: different aesthtic shapes of poles (thanks to the material workability)
- CONS: high prices of raw material
WOOD
- PROS: perfect for green and high conservation value areas
- CONS: high prices and shorter duration.
STAINLESS STEEL
- PROS: high resistance to corrosion and better aesthetic. Low maintenance and greater security.
