Cold form steel has proven itself in the commercial building industry in the US and Europe for more than 70 years.
Innovative New Zealand developers, engineers, and architects, of mid to high density residential developments are starting to make the switch to cold form steel as it has proven its ability to save time and money.
7 reasons architects, engineers and builders prefer cold form steel framing and truss.
Predictable and accurate
Steel components bring efficiencies to the process by enabling assembling on site rather than building, which allows follow-on trades to get to work sooner. Shorter construction cycles leads to savings in P & G, earlier return on investment and reduced interest charges. Time-related savings can be as much as 10% of the overall project value, reducing the building owner’s requirements for working capital and improving cash flow.
100% recyclable with minimal waste
Steel is one of the most sustainable building materials in the world. Precision Steel is manufactured in New Zealand from locally mined iron-sand and a component of recycled steel. The roll forming technology behind steel framing allows fabrication to exact specifications, so there is minimal onsite wastage and in many cases none and waste produced is 100% recyclable. All steel can be recovered and recycled again into new high quality products.
Lighter & Cheaper
Cold Formed Steel has an extremely high strength to weight ratio - 30% of the weight of timber but twice as strong. This results in a lighter structure that can carry the same building loads. This allows the designer to reduce the mass at the foundation, cutting costs for concrete, formwork and equipment.
Being 30% lighter than timber means Cold Formed Steel is safer to work with. Steel has none of the additional preservative chemicals associated with timber, an important consideration for the health of builders and tradesmen working on site.
Cold Form Steel is very suitable for 3D modelling using BIM software. This enables accurate integration of services in advance.
Steel’s high strength-to-weight ratio allows for greater design freedom, but more importantly, a lighter frame means less mass for an earthquake to displace resulting in lower damaging forces acting on your building.
Unaffected by weather
Cold Formed Steel does not warp, twist, or bend when exposed to the elements. It is unaffected by wet weather delays and does not require drying out.
Fast becoming the global industry standard.
While some might consider cold formed steel framing to be a “new” construction product, it has actually been used in North America for over 70 years and is now considered the industry standard across the USA and much of Europe. Several 8-storey buildings have been constructed in these countries using Cold Formed Steel framing. The first 8-storey building in the USA was completed in 1999 in Seattle, Washington (known for high seismic activity).
Mid-rise buildings (5 or 6 levels) are very common and many have been built around the world in the past 20 years. Speaking from an engineering point of view, there is no theoretical storey limit when using Cold Formed Steel framing.
