Vantablack is a super black coating developed in 2014 by Surrey NanoSystems, a British company. The materials to which this coating is applied absorb 99.965 percent of light. This makes it the blackest known man-made coating.
What Is the Difference Between Steel and Aluminum Light Poles?

Light poles used in outdoor lighting applications such as roads, surroundings, parks and gardens are made of steel or aluminum material. Both materials have advantages and disadvantages in certain applications.
Aluminum alloys commonly used in the lighting industry are heat treated 6061 and 6063. Both types of aluminum used in the production of decorative lighting poles and flag poles have high strength properties. Another advantage of aluminum is its excellent corrosion resistance for use in harsh outdoor conditions.
Steel is a higher strength material. Steel poles are used if they will be used in a windy area and will carry heavy loads (lots of lighting fixtures, flags and signage). In order for the steel to be resistant to outdoor conditions, it must have a suitable surface coating (galvanized, paint, interior paint, primer).
Cost is an important factor to consider in any project. The raw material cost has a direct impact on the finished product price. The price of steel and aluminum fluctuates constantly depending on the balance of global supply and demand. However, steel is generally much cheaper than aluminum.
The biggest feature of aluminum material is that it is resistant to corrosion and rust without the need for any other treatment. If steel is to be used in a humid or corrosive environment, it should be galvanized or painted.
Aluminum is a softer and more elastic metal than steel. With this feature, aluminum can be bent as desired and decorative pole designs can be obtained. Steel, on the other hand, is a very strong and durable metal, but it does not come close to the flexibility of aluminum for forming.
Steel is much heavier than aluminum. Generally speaking, steel is 2.5 times denser than aluminum. Although aluminum seems to be much more expensive (approximately 3 times) when steel and aluminum raw material weight prices are compared, it is seen that aluminum is approximately 30 percent more expensive in practice when the volume cost is deducted.
