Product Overview

YX35-240-720 floor decking sheet, also known as metal floor deck, galvanized deck panel, or steel floor decking, is a cold-rolled, roll-formed structural panel manufactured from high-quality galvanized steel. Its profile typically features V-shaped, U-shaped, trapezoidal, or other wave-like cross-sections designed to enhance load distribution and bonding with concrete.

Originally developed for roofing applications in industrial buildings, modern steel deck systems like the YX35-240-720 have evolved to become essential components in composite floor slab construction, acting as permanent formwork as well as a reinforcement system in multi-story steel structure buildings.

Application Scenarios

The YX35-240-720 steel floor deck is widely applied in various steel frame buildings and infrastructure projects, including:

Power plants and energy facilities

Automotive showrooms and exhibition halls

Industrial warehouses and cement storage buildings

Commercial buildings and steel structure offices

Transportation hubs: airports, railway stations

Stadiums, gymnasiums, theaters, and large public venues

Logistics centers and large-scale supermarkets

Urban infrastructure and public buildings (e.g., Olympic venues)

Its high adaptability to fast-track construction makes it ideal for multi-floor slab construction, enabling simultaneous multi-deck concrete pouring and layered slab work.
