Recently, the steel structure expansion project of Velana International Airport in Maldives successfully obtained LEED v4 Gold certification. As a globally recognized authority on green building, this certification signifies that the project has met international top standards in sustainable design, low-carbon construction, and eco-friendliness. It represents a comprehensive and high-level recognition from an authoritative organization for the project's site planning, energy utilization, low-carbon building materials, ecological protection, and indoor environmental quality.
01 Extreme island operating conditions, ensuring safety and durability

The Maldives experiences high temperatures, humidity, salt spray, and frequent strong typhoons, imposing stringent requirements on steel structures in terms of corrosion resistance, wind resistance, and seismic resistance. Duowei has specifically designed for the island environment:
① Highly corrosion-resistant steel structure system and long-lasting protective coating effectively resist long-term erosion from marine salt spray, extending the entire life cycle of the structure;
② Through specialized calculations for wind pressure resistance and seismic resistance, the overall steel structure meets the high safety level requirements of airport buildings:
③ Factory prefabrication and modular assembly reduce on-site welding and construction pollution, meeting the LEED green construction requirements.
02 Low-carbon steel structure, facilitating high LEED score compliance

LEED Gold certification has strict standards for building materials, emphasizing low carbon footprint, recyclability, and low energy consumption. The steel structure system provided by Duowei aligns with green principles:
① Use recyclable steel materials, ensure low energy consumption and low emissions during production and construction, and meet the scoring criteria for "materials and resources";
② Steel structures have light self-weight and large span, which not only optimizes spatial layout but also reduces the overall carbon emissions from foundations and building materials;
③ High-precision steel components provide precise support for energy-saving enclosures, curtain walls, and other systems, helping the terminal building reduce energy consumption and improve energy efficiency.
03 Intelligent and efficient delivery, escorting portal projects

Leveraging a mature industrialized intelligent manufacturing system and standardized construction model, Duowei provides one-stop services for projects. Relying on the EPD environmental product certification for steel structures, we empower projects with the advantages of low-carbon environmental protection throughout the entire life cycle, enabling them to achieve LEED Gold certification.
① Key components such as steel columns and steel beams are produced in a standardized manner in the factory, with millimeter-level precision control, facilitating efficient on-site construction;
② Implement quality control from source to end, and fulfill the commitment of zero pollution into the sea;
③ Pass the international third-party inspection and owner's acceptance at one attempt, demonstrating corporate responsibility and Chinese quality.
In the future, Duowei will continue to uphold the concept of "green innovation and intelligent manufacturing for win-win", deliver the strength of Chinese enterprises through more overseas benchmark steel structure projects, and continue to write a new chapter of brilliant Silk Road cooperation.
