As you would expect a highly designed and tested construction profile from one of the world’s leading innovative metals companies has numerous advantages over conventional flooring methods and the direct competition:

Superior Performance:
The ComFlor® range of profiles are arguably the most efficient currently available anywhere in the world:

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

Efficient:
Due to the intrinsic efficiency of composite construction and the displacement of concrete by the profile shape, considerably less concrete is used than in conventional reinforced concrete construction. This reduces the size and cost of elements used in the primary structure and the foundations.

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 Tata Steel and The Steel Construction Institute have resulted in fire ratings of up to four hours being available with the use of light mesh within the composite slab and no protection to the deck.

Speed:
Large bundles of up to 110m2 of deck can be rapidly craned into position, reducing traffic disruption and overcoming ground level storage issues. 400m2 can be laid by one 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. Superior design typically means propping is not required. 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 difficult to access zones. Two workers are able to lift and install 10 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 deck acts as a lateral restraint and forms a diaphragm, transmitting wind load from the outer steelwork to the core. Therefore once the decking is fixed, it contributes significantly to the stability of the structure.

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

Gauge options:
ComFlor 80 and ComFlor 60 are available in a range of gauges from 0.75mm to 1.2mm so that the deck thickness can be optimised to the project requirements, minimising the cost of the deck.

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 the cost of propping and minimising mesh, while enhancing crack control in the slab.

Faster rental returns:
The speed of ComFlor® compresses the construction programme meaning that tenants can move into the building earlier giving faster rental return.

Less additional cost:
ComFlor’s unique shape reduces construction deflections, minimising concrete usage and leading to substantial savings on large projects. A high inherent fire rating often means additional fire protection, and the associated cost, is not required.

Local content:
The coil is sourced from New Zealand steel using locally sourced iron sands
– reducing transport and handling impacts.

Recycled content:
Twelve percent recycled material is used in the manufacture of ComFlor® coil stock.

Energy efficient:
The composite nature of the steel used with concrete means the ongoing benefits of thermal mass can be utilised to stabilise temperatures in the living environment and minimise energy use.

Recyclable:
The steel used in ComFlor® is fully recyclable at the end of the building’s life.
