Shanghai Tower

Project overview

Shanghai Tower is 632 m tall with 121 floors and a total floor area of about 576,000 m², China's tallest building. The brand's manufacturer provided Interchar® intumescent fire protection for its stairwell and curtain-wall-supporting steel structures; the project is included in the AkzoNobel brochure.

Anti-corrosion (fire protection) challenge

• The fire resistance limit for the super-high-rise evacuation passages and curtain-wall-supporting steel structures is 1.5 hours;
• The high-altitude working surface is narrow, making wet film thickness and sag control difficult;
• In the coastal C3 environment, the fire protection coating shall be applied over an anticorrosive primer.

Coating system

*The table lists the coating systems or system directions recorded in the manufacturer's documentation; specific models and film thicknesses are subject to the project technical documents.
