Floor Deck

Floor deck (also called steel floor deck or composite floor deck) is a high-strength, lightweight steel building component. It is made of galvanized steel sheet or color steel sheet through roll forming, designed with special ribbed or corrugated structures. As a key part of composite floor systems, it serves as both a permanent formwork during construction and a load-bearing component after concreting, widely used in industrial workshops, office buildings, shopping malls, prefabricated buildings, and high-rise structures.

Core Characteristics

Exceptional Structural Strength: The ribbed/corrugated design enhances load-bearing capacity and rigidity. It can withstand concrete weight and construction loads without additional temporary formwork.

Lightweight & Space-Saving: Made of thin-gauge steel (usually 0.8-2.0mm thick), it reduces the overall building weight while maximizing floor space utilization with its slim profile.

Efficient Construction: Prefabricated with standardized lengths and widths, it enables quick on-site laying and splicing. It shortens the construction period by 30-50% compared to traditional concrete formwork.

Durable & Corrosion-Resistant: The galvanized surface (zinc coating thickness ≥120g/m²) or color-coated finish provides strong anti-rust and anti-corrosion performance, extending the service life to 20-30 years.

Composite Synergy: When combined with concrete and steel bars, it forms a composite floor system. The steel deck and concrete work together to bear loads, improving structural stability and seismic performance.

Typical Applications

Multi-story and high-rise buildings: Office towers, residential buildings, and hotel floors.

Industrial and commercial spaces: Factory workshops, warehouses, shopping malls, and exhibition centers.

Prefabricated and modular buildings: Modular houses, temporary offices, and portable buildings.

Special structures: Stadium stands, parking garages, and mezzanine floors.

Renovation projects: Floor reconstruction and expansion of old buildings.
