Hanxing DC-W688 Floor Decking

The Hanxing DC-W688 floor decking is an open-type profiled steel deck specifically designed for reinforced concrete composite floor systems. It corresponds to the widely used industry profile YX51-240-688, with an effective coverage width of 688 mm, wave height of 51 mm, and wave pitch of 240 mm.

Manufactured by Hanxing Steel Structure using high-strength hot-dip galvanized steel coils and fully automated CNC roll forming technology, this floor decking offers high strength, excellent rigidity, fast installation, and the ability to replace traditional formwork systems. It is widely used in multi-story and high-rise steel structure buildings, industrial plants, shopping malls, office buildings, and warehouses.

The decking can be directly used as permanent formwork during concrete pouring and works compositely with concrete after curing, forming an integrated structural slab that significantly improves overall structural performance and construction efficiency.

2. Structural Features

The DC-W688 floor decking adopts a high rib trapezoidal profile, providing a large moment of inertia and strong bending resistance. After installation, it can directly support construction loads, reinforcement weight, and wet concrete without requiring full scaffolding support systems.

• High rib design ensures strong load-bearing capacity

• Interlocking side laps provide tight and secure connections

• Excellent flatness after installation ensures uniform slab performance

• Strong bonding with concrete improves composite action

• Finished floor slab has high integrity and crack resistance

3. Performance Advantages

High Strength and Rigidity

The 51 mm high rib profile provides excellent load-bearing capacity, suitable for medium to large span floor systems.

No Formwork Required

Acts as permanent formwork, eliminating the need for traditional wooden molds and support systems, reducing labor and material costs.

Fast Construction Speed

Quick installation allows for overlapping construction processes, significantly shortening project timelines.

Composite Structural Performance

Works together with cast-in-place concrete to form a composite slab with excellent load distribution and seismic performance.

Corrosion Resistance

High zinc coating provides long-term protection against rust and corrosion, ensuring durability in concrete environments.

Fire Resistance

When combined with concrete cover, it meets building fire resistance requirements.

Optimized Weight

Reduces floor dead load and lowers structural requirements for beams columns and foundations.

4. Application Scenarios

The Hanxing DC-W688 floor decking is widely used in various steel structure floor systems, including:

• Multi-story and high-rise office buildings hotels and residential apartments

• Industrial factories workshops and warehouse floors

• Shopping malls supermarkets exhibition centers and sports venues

• Logistics centers data centers and industrial parks

• Renovation projects structural additions and steel platform floors

• Modern construction projects requiring high strength and fast installation

5. Installation Features

The Hanxing DC-W688 floor decking is fixed to the upper flange of steel beams using shear stud welding. Installation typically proceeds from the center outward or from one end to the other.

• Panels are connected through side interlocking without additional fasteners

• After installation reinforcement bars can be placed directly

• Electrical and plumbing systems can be integrated before concrete pouring

• Concrete can be poured immediately after deck installation

• No complex equipment required standard construction teams can complete installation efficiently

This system is especially suitable for fast-track construction and large-scale standardized building projects.

6. Product Advantages Summary

The Hanxing DC-W688 floor decking features a mature profile design, rational structural performance, and excellent cost efficiency. It is one of the most widely used open-type steel decking systems in steel structure construction.

• High dimensional accuracy and stable forming quality

• Uniform zinc coating and clean surface without defects

• Suitable for medium to high-rise buildings large spans and high load requirements

• Combines safety economy and construction efficiency
