Singapore Changi Airport T 5 Substation Construction

Project Overview

As a trusted steel solutions provider, CUMIC is proud to contribute to one of Singapore’s Changi Airport Terminal 5 (T5). This landmark development represents a new era in aviation, innovation, and sustainable infrastructure, positioning Changi among the world’s most advanced airports. The upcoming Changi Airport Terminal 5 is part of the massive Changi East Development, covering runways, tunnels, taxiways, and supporting utilities.

In support of this transformative project, CUMIC supplied 3,014 tons of Hot Rolled Plates (HRP) S355J2 for the Changi T5 Substation, marking a top-up order for this critical facility. Once completed, Terminal 5 will be comparable in size to Terminals 1 through 3 combined, boosting the airport’s total capacity by up to 50 million passengers annually.

Why S355J2 Is the Perfect Choice

EN10025 S355J2 structural steel is known for its superior mechanical properties, making it an excellent material for heavy-duty infrastructure and industrial applications.

• High Yield Strength: Delivers exceptional structural integrity for demanding load-bearing applications.

• Excellent Weldability: Ensures efficient fabrication without compromising performance.

• Impact and Corrosion Resistance: Performs reliably in Singapore’s humid tropical climate.

• Long-Term Durability: Provides strength and stability essential for mission-critical facilities like substations and power plants.
