Zhengzhou Xinzheng International Airport is the principal airport serving Zhengzhou, the capital of Henan province, in China. Since 2018, it has been the busiest airport in central China in terms of both passenger and cargo traffic. Elval Colour’s high quality product orofe^® pente was selected for the construction of the airport. The subsequent controls carried out throughout the construction phase have ensured that the roof made of orofe^® pre-painted aluminium sheets was manufactured and installed in line with the necessary requirements, ultimately guaranteeing its aesthetic and structural integrity for many years to come.

 

 

 

The aim of the team of architects was to use eco-friendly materials and to achieve temperature and ventilation control of the building. However, the architectural design required an elegantly curved roof, and this is why Elval Colour’s product, orofe^®, was selected for the roof, thus creating uniform smooth curves. 

 

 

For Zhengzhou Xinzheng International Airport, which extends over an area of 400,000 sq.m., painted standing seam aluminium panels coated with Elval Colour’s orofe^® pente were selected and installed. The specially manufactured AA 5754 1 mm aluminium alloy was covered with a non-standard PVDF 80/20 coating, which had been adapted to the architects’ specifications. This high quality material was selected based of the building’s configuration and bending requirements, whose streamlined appearance is defined by its modern construction design and innovative materials, thus raising the bar with regard to the aesthetic appearance of airports all over the world. The series of painted orofe^® aluminium materials, used as the main exterior material for each individual roof system, provides considerable advantages, including temperature and ventilation control. 
The global air transport system is one of the main pillars of growth in the construction sector. Nevertheless, one cannot deny its role in procedures that have an impact on the environment. The modern orofe^® roof paint systems provide functionality, resilience, aesthetics, and energy savings. An airport’s location and environmental conditions play an essential role in selecting the materials for a building’s façade or roof and affect considerations such as resilience, aesthetic result, functionality, and costs. Elval Colour is particularly attentive to making the right choice in terms of the tint, the chemistry of the building’s paint system. 
The company created a final product which satisfied the performance, robustness, and aesthetic criteria set forth by both the owner of the project and the architecture firm. The roof of Zhengzhou Xinzheng International Airport has been constructed to last through time, orofe^® being also non-combustible and resistant to ultraviolet radiation, while requiring minimal maintenance or cleaning.
