This article analyzes the anti-corrosion and fireproof design of steel floor deck systems. Grounded in ISO 12944, it emphasizes that galvanization strategies must match environmental corrosivity for both Open-type and Closed-type Steel floor Decks. Referencing ASTM E119, the paper debunks the myth that closed profiles offer thermal insulation, asserting that concrete cover thickness is the sole determinant of fire endurance. By comparing structural performance, it provides scenario-based selection guides, proving that Closed-type Steel floor Deck offers superior composite efficiency, while Open-type Steel floor Deck remains the most cost-effective solution for standard projects.
Steel structures are increasingly favored over concrete for commercial buildings, boasting remarkable market growth. They cut construction time by 30%-50% and deliver 15%-25% lower long-term costs thanks to lighter weight, less labor and reduced maintenance. Featuring wider spans and slimmer columns, steel buildings offer flexible layouts and easy renovation. They excel in seismic resistance, durability and fire safety, and gain edges in recyclability and carbon reduction. Practical cases prove its merits, making steel construction the mainstream trend of future commercial architecture.
This article focuses on recyclable steel floor deck, a key part of steel structure, in the green building revolution. It emphasizes steel’s 100% recyclability, low embodied carbon, composite construction efficiency, and role in green certifications, supported by authoritative data, highlighting its future-proof value.
