Detailed Product Description

Our Long-Span ComFlor 210 Equivalent Steel Bridge Deck Forms are high-rigidity, deep-profile composite steel decking solutions specially developed for large-span bridge and heavy industrial building projects. Different from conventional shallow deck profiles, the 210mm ultra-deep trapezoidal structure delivers outstanding spanning capability and superior section mechanical performance.

As a fully certified ComFlor 210 alternative, our panels completely match the original profile’s structural parameters, embossment design and composite bonding performance. It can be directly adopted in finished engineering designs without modification, perfectly solving the problem of single-brand supply restrictions.

Adopting G550 high-tensile steel base material and full hot-dip galvanized anti-corrosion treatment, this deck system serves as both permanent load-bearing formwork and tensile structural reinforcement. It forms an integral composite structure with cast-in-place concrete, significantly improving the overall stiffness, bearing capacity and stability of bridge decks and floor slabs, helping projects achieve larger clear space, lighter steel structure and lower comprehensive cost.
 

1. Professional Long-Span Engineering Design

ComFlor 210 is the industry benchmark for super long-span composite decking, widely used in large bridges, industrial workshops and large public buildings with high span requirements. Our equivalent profile strictly replicates the original high moment of inertia and section modulus through finite element structural simulation.

The prominent engineering advantages are reflected in:

• •Greatly expanded unsupported clear span, reducing the quantity of intermediate steel beams
• •Lower overall steel tonnage of the main structure, reducing structural self-weight
• •Decreased foundation bearing pressure, saving foundation engineering cost
• •Optimized indoor clear height and space layout, improving building utilization

This long-span design fundamentally simplifies the structural frame and brings remarkable economic and architectural benefits for large-scale infrastructure.
 

2. Complete Profile & Material Technical Parameters

All specifications support personalized customization according to project span tables, load grades and environmental conditions.

3. Reliable Composite Structural Synergy Performance

The surface of our ComFlor 210 equivalent deck is designed with professional mechanical embossments and rib structures. After concrete pouring, the steel deck and concrete form firm shear bonding and composite action.

This integrated composite structure effectively solves common problems of traditional formwork:

• •Avoids relative sliding between steel and concrete
• •Uniformly distributes bridge deck vehicle dynamic loads
• •Improves overall slab bending resistance and structural toughness
• •Reduces long-term creep deformation and structural fatigue

It is extremely suitable for heavy traffic bridge decks, large-span industrial floors and high-load commercial building floors.
 

4. Simplified Construction & Improved On-Site Efficiency

Thanks to its ultra-long-span performance, the ComFlor 210 deck system greatly optimizes the construction process:

• •Eliminates dense temporary scaffolding and multi-layer propping systems
• •Reduces repeated supporting, dismantling and material transportation work
• •Covers a single large area with fewer panels, lowering hoisting times
• •Precisely factory pre-cut size realizes rapid positioning, welding and bolting

The streamlined construction process shortens the closing cycle of steel structure and concrete construction, improves site safety and creates cross-working conditions for other disciplines.
 

5. Superior Anti-Corrosion & Long Service Life Adaptability

All panels adopt integral hot-dip galvanizing process, with uniform zinc layer adhesion and strong cathodic protection capability. The zinc coating can effectively isolate air, moisture, deicing salt and coastal corrosive media, and provide automatic repair protection for cutting edges and scratches.

Different coating grades can be matched according to project location:

• Z350: Suitable for inland urban and common industrial environments
• Z450/Z600: Suitable for seaside, port, offshore bridge and high-humidity corrosive areas

Greatly reduce later maintenance, repair and replacement costs, realizing long-term maintenance-free service.
 

6. Factory Customization & Professional Engineering Support

We provide full-process customized solutions for global engineering projects:

1. •Customize steel thickness, coating weight and panel length according to project span and load requirements
