Steel Framing the smarter way to build

Building with steel is becoming the preferred building solution for the future. Many of New Zealand's leading builders are switching from timber to steel for house framing, and there are sound reasons for it. Not only is it better for business, but it is often better for the new owner to live in too.

CH Engineering are very proud to use steel products supplied by Alrite Steel & Services NZ Ltd.

Benefits for the builder

Faster and easier to install

Perfectly straight walls & ceilings no warping, buckling, moisture, swelling or movement, no delays waiting for frames to dry. Every piece comes labelled and cut to length reducing work & waste on site, with prepunched holes for pipes & wiring reducing the work of other trades.

Trouble free

It's an end to end process from design to construction, while still offering design flexibility. Steel frames are durable and do not distort, so there are fewer call backs. C.H.Engineering will assist on your first few jobs with on-site training & supervision if needed. There is almost no set-up cost to start steel framing as you will already have most of the tools.

Strong and lightweight

C.H.Engineering uses 0.75mm steel, 30% thicker than most other steel frames in NZ homes. This thicker steel specification combined with very high strength to weight properties means frames never distort, are easy to handle, have greater strength for longer spans and higher walls where needed.

Cost competitive

Steel is the building material of the future. CH Engineering will be ensuring that framing prices are competitive with conventional timber framing, allowing you to enjoy the additional onsite advantages of faster, smarter construction.

50 Year Frame Warranty

This is provided by C.H.Engineering, who use high quality galvanised steel, well- tested fasteners and technology from FRAMECAD - world leaders in steel framing technology.

Benefits for the customer

The price

Steel is competitive against timber and with a shorter build time, there is less labour to pay for.

Peace of Mind

There is a 50 Year Warranty on all steel framing. It will not rot, warp or expand, so the house stays watertight. And because it won't rot it's also healthier to live in. Steel is resistant to fire, as well as borer and termites. A solid investment!

It's greener

Light gauge steel is sustainable and a great environmental choice. There is also no waste Every piece is cut to precise length, punch, predrilled, labelled and often assembled before it leaves the factory.

Generally the framing will come to the site perfectly fitting, but if alterations are required it is handy to have a quality pair of aviation snips. You'll also need a cordless impact driver with a selection of bits, including 150mm bits for the deep corners, and either a 34mm hole saw or 34mm stud punch. There is no welding equipment needed.

Frequently Asked Questions:

A: It's very light. Ready made frames can be lifted into position and fixed very quickly. The frames don't absorb moisture, so there is no delay waiting for frames to dry. Service holes are already pre punched, so subbies can also get in and out much quicker.
A: Steel doesn't absorb water, warp, expand or rot, so is less prone to water problems due to movement. It also doesn't have any of the preservative chemicals associated with timber and is electrically safe and fire resistant.
A: You can fix the same products to steel framed homes as you would with timber. Gib board lining is glued and screwed to the frame, and externally thermal breaks are fixed to the frames before building wrap is applied and cladding fixed.
A: Just as with a timber house, foundations and walls may need to be strengthened if they were not initially designed for the extra storey. The principals are the same as with traditional building, but use an engineer who has experience with steel framing. Likewise, moving walls that are load bearing require an engineer. The advantage of a steel wall is that it can be disassembled and reassembled in position- often with just a screw gun.
A: There are very few risks. The frames can be erected by almost anybody, forming extremely straight and true walls. Wall linings, kitchens and internal cabinets are easily fitted and the high build quality means fewer builder call backs.
A: As steel becomes more mainstream, councils are more familiar with consenting plans for steel framed homes. Usually the fabricator (C.H.Engineering) will supply engineered detail drawings for your consent submission.
A: Yes, isolation systems will provide additional sound insulation, provided they are not too thick. Always refer to the manufacturer's recommendations.
