About Floor Decking Sheet
Composite Steel Deck for Concrete Slabs
Steel Floor Decking Sheet is roll-formed from galvanized steel coils, serving as permanent formwork for concrete slabs. It acts as both a working platform during construction and provides composite action with concrete under service loads, functioning as both formwork and reinforcement.
Widely used in high-rise buildings, commercial complexes, industrial plants, and parking structures. Our floor deck systems meet international standards including ASTM A653, JIS Standards, and GB/T 12755.
Core Benefits: High Load Capacity • Fast Construction • Fire Resistant • Cost Saving.
High Load Capacity
Superior strength-to-weight ratio design ensures excellent load-bearing performance under concrete and live loads.
Fast Construction
Eliminates traditional formwork — no temporary shoring needed. Reduces construction time significantly.
Fire Resistant
Steel deck provides excellent fire rating performance. Composite action with concrete enhances overall fire resistance.
Cost Saving
Reduces labor and material costs. No formwork removal. Faster floor cycle means earlier project completion.
