ROSA thus offers an unrivalled and extensive range of aluminum products for exterior lighting on the market with high corrosion-resistant and decorative qualities. Aluminum luminaires, lighting columns as well as extension arms are available in 10 unique anodized colors.
ROSA produces hard anodized lampposts
These lampposts last much longer than steel lampposts or brushed aluminum lampposts.
ROSA lampposts are made of hard anodized aluminum.
The Brinell hardness is indicated as HBW in the most commonly used test standards (ASTM E10-14 and ISO 6506–1:2005).
H stands for the hardness, B for Brinell and W for the material of the intruder: tungsten carbide.
Steel S235 has a hardness of approximately 100 HBW.
Normal aluminum has a hardness of 15 to 20 HBW, the outside of hard anodized aluminum has a hardness of 200 HBW or higher.
In addition, hard anodized aluminum is resistant to acids and salts and UV radiation.
The expected lifespan of the hard anodized aluminum ROSA lampposts is more than 50 years.
