The Kingdom of Saudi Arabia has built a massive network of modern roads (97,000 km) linking all parts of the country. This makes road transportation very important for Saudi Arabia and the new Aramco conditions for the transfer of petrol have led to the search of foreign companies to provide aluminum-tank vehicles to replace the iron ones.
Aluminum tanks do not interact with the fuel transported inside, reducing evaporation rates, have a longer life span, are bigger and can hold 42,000 liters (against the 37,000 liters of the iron tanks) and have a lower weight (7 tons against 8-10 tons of the iron tanks).
