Sinopec Free Trade Zone Tower is located in the start-up area of Haikou's Jiangdong New District. It is a regional headquarters base built by Sinopec Group, with a total construction area of nearly 110,000 square meters and a designed height of 150 meters. It features a diamond-shaped outline and self-shading design. The project is positioned as a regional headquarters base and, upon completion, will develop high-end industries such as international energy trade, financial services, and e-commerce. 

The glass curtain wall adopts an innovative design. Its facade is composed of 5,200 pieces of glass in over 500 different styles. The dynamic and transparent design of the arcade shape restores the architectural plan. The glass and aluminum panels are joined at a 90-degree angle to form a "zigzag curtain wall", which not only broadens the viewing field but also achieves shading and sound insulation through the aluminum panels. The perforated aluminum panels can also provide ventilation.
