ComFlor®

Superior Performance

A highly designed and tested range of metal profiler from one of the world’s leading innovative metals companies, providing industry leading innovation and technical support for the widest range of design options in New Zealand.

The ComFlor^® range of profiles are arguably the most efficient currently available anywhere in the world.

Span

Our profiles have the best unpropped span capabilities of any steel decking in New Zealand. Better spans means fewer beams are required to support the structure.

• ComFlor SR unpropped double spans up to 3.8m
• ComFlor 60 unpropped double spans up to 4.0m
• ComFlor 80 unpropped double spans up to 5.0m
• ComFlor 210 propped span to 8.5m

Efficient

The ComFlor range of four profile shapes in up to four base metal thicknesses allowing the designer to design the most efficient structure possible.

Structural integrity

Elimination of temporary propping during construction, leaves the structure with better long term structural integrity, and improves crack control in the slab.

Weight

Reduced weight relative to competing systems provides advantages in seismic, gravity and foundation design.

Height

Composite beams use the slab as a compression element, which increases stiffness and reduces their size. These savings translate to a reduced floor zone and therefore a reduced overall inter-storey height, allowing the possibility of additional revenue generating floors being added.

Fire

Extensive testing and fire engineering work by The Steel Construction Institute have resulted in test result enabling up to 4 hours of fire rating.

Using the ComFlor^® design software allows for fire design up to 2 hours, using mesh alone.

Simplicity (Ease of Construction)

ComFlor^® is very simple and fast to install:

Speed

On site a standard 1 tonne crane lift can contain over 80m2 so the whole floor area can be rapidly craned into position, reducing traffic disruption, and overcoming ground level storage issues. 250m2 can be laid, trimmed, and stud welded by each two men team per day. And with minimal mesh reinforcement and pumped concrete, the completed floor can quickly follow.

Props eliminated

Temporary props can usually be eliminated during design process, utilizing the extensive unpropped options in the ComFlor^® range. The result is faster erection and a shortening of the construction programme.

Lightweight and easy to handle

ComFlor^® is light weight and easy to handle, even into zones with difficult access. Two workers are able to lift and install 12.00 metre sheets.

Working Platform

Once laid, the deck acts as a safe working platform for all subsequent subtrades and as a safety barrier to overhead hazards.

Construction Stage Bracing

The ComFlor^® can be designed to provide lateral restraint and form a diaphragm, transmitting wind load from the outer steelwork to the core prior to concrete placement. This allows for multiple levels of steel structure and decking to be installed without being concreted but still maintain building stability.

Good for services

ComFlor^® composite floor decks incorporate systems for the easy attachment of suspended services, negating the requirement to fix into concrete. Slab penetrations up to 300mm can be formed without the need for additional reinforcing. Larger openings can be incorporated with the use of additional reinforcing or structural steel.

Cost Efficient Construction

ComFlor^® is the most cost efficient mid-floor solution available:

Gauge options

ComFlor^® SR, ComFlor^® 60 and ComFlor^® 80 are available in a range of 4 gauges from 0.75mm to 1.2mm so that the deck thickness can be optimised to the project requirements. ComFlor 210 comes in 1.25mm nominal thickness.

Less structural components required

Longer spans with fewer beams means a more cost effective build.

No propping

Elimination of the need for temporary propping saves money on materials and labour.

Faster investment returns

The speed of ComFlor^® compresses the construction programme meaning that tenants can move into the building earlier giving faster financial return.

Less additional cost

The shape of ComFlor^® 60, ComFlor^® 80 and ComFlor^® 210 reduces construction deflections, minimising concrete usage and leading to substantial savings on large projects. ComFlor^® SR utilises the additional concrete to enhance acoustic and fire properties, minimizing the need for additional treatments.

Value engineering

We can undertake value engineering for ComFlor decking systems to optimize material usage, reduce overall project cost, and improve construction efficiency. This includes reviewing deck profiles, slab thickness, reinforcement requirements, and span arrangements to ensure the most economical and structurally efficient solution while maintaining compliance with design standards and performance requirements.

Sustainable Construction

ComFlor^® is a very sustainable solution:

Local content

The coil is sourced from New Zealand Steel using locally sourced iron sands – reducing transport and handling impacts.

Recycled content

Steel is endlessly recyclable and with New Zealand Steel new arc furnace the use of recycled material for ComFlor is optimized.

Testing

ComFlor^®’s profiles are thoroughly tested so you can have confidence they will perform.

UK testing

All ComFlor^® profiles have been tested by Imperial College London. This preeminent institution carries out an extensive range of recognised laboratory tests to derive values for the construction and composite stage. This testing has been independently verified by the United Kingdom’s Steel Construction Institute.

New Zealand testing

Steel & Tube has carried out independent testing on ComFlor^® 210 profile to verify alignment with Standards in New Zealand.

Fire testing

Full fire testing has been carried out by Warrington University of the United Kingdom.
