In order to realize the idea of the fairy castle in Ba Na, the project owner and the architect of the project are extremely difficult to choose the capable and professional contractor to execute the project. Because of Ba Na's characteristic of the location on the top of the mountain with an elevation of 1489m above sea level, the climate changes by the hour, the time of fog cover makes up most of the day, making it difficult to transport objects. materials, construction schedule and safety. On the other hand, the project's iconic architectural architecture also requires a quality solution from a professional contractor.

Overcoming many other contractors, E-Power Engineering Co., Ltd. is trusted by the Sun Group investor to be responsible for the construction of all 11 square and round tower roofs for the project. domestic and international roof systems, complex design projects are not difficult for E-Power, investors and architects are satisfied with E-Power's solution.
For Ba Na Hill project, choosing roofing materials is really a headache issue: Aesthetics, durability and, importantly, the optimal cost?
Use Aluminum? Aluminum is durable and reasonably priced, lightweight, does not change much during transport. But modern aluminum does not exude the elegance and mystery of the castles in the fairy tale.
Is the tile okay? The tiles were cheap, but heavy and it took a long time to cover the moss. Moreover, the construction method to roof tiles on the top of the sharp towers will cost a lot, and the risks in construction are also great. Therefore, this is not the best solution. It seems that the aluminum solution is still more optimal. However, to get the look of ancient, we can use gold-plated aluminum. But using gold, the cost will push a lot, the risk of theft also increases.
Among thousands of options but none of them were truly effective, after analysis, E-Power proposed using copper. The reason for using Copper is because:
-Copper is not a rare metal and is commonly used in specific construction projects around the world. Therefore, the supply of copper is not at risk of theft or difficulty due to scarcity, so the cost of use is therefore much more economical.
- Copper is less changed during transportation, can bend in many shapes of the roofs without cracking or leaking.
- Regarding durability, the copper roof can be used for hundreds of years. If not used anymore, the remaining value of the copper is large, contributing to reducing initial costs down Aesthetically, copper's gold color both expresses the elegance of castles and changes the color over time due to the oxidation reaction of copper with oxygen. Naturally, the copper roof will bring ancient and mysterious colors. This proposal is completely unanimous and agreed by the investor and architect. However, the project's characteristics are at the top of the mountain, the construction is also a great challenge.
