Open Profile Galvanized Composite Floor Decking Sheet – Steel Structure Grade
Product Overview
Galvanized composite floor decking is a structural profiled steel sheet designed for steel frame building floor systems. Manufactured by roll forming galvanized steel coil into trapezoidal profiles, it serves as permanent formwork during concrete pouring and integrates with cured concrete to form a composite floor slab. This open profile grade is the most widely used floor decking system, delivering fast construction, reduced formwork cost and reliable structural performance for multi-story steel buildings.
Why Choose CNB Floor Decking?
We manufacture floor decking on high-precision roll forming lines using only high-quality galvanized base coils, ensuring consistent profile dimensions and coating integrity. Every sheet undergoes dimensional verification and load testing to guarantee structural performance. We offer a full range of standard profiles and thicknesses, and can develop custom profiles to match specific project requirements. With fast cutting and fabrication capabilities, we support both small and large construction projects with short lead times.
