LYSAGHT® Cold Formed Sections
Product Description and Features
BlueScope Lysaght cold formed steel channels and angles are roll-formed from zinc coated and uncoated material. The strength of BlueScope Lysaght's cold formed sections has been increased from 240 and 250MPa to 300MPa for both the zinc coated and uncoated products, increasing the structural capacity of the steel channel and angle sections. These sections have many uses in the construction, general fabrication and home handyman fields.
- Many combinations of sections are possible
- Sizes of several plain channels enables them to nest readily
- Normal box sections are easily fabricated
- Machine controlled dimensions allow a neat fit and provide an easy method of assembly for sliding joints
- Able to be welded or bolted.
Common Uses of this product
Structural: Building frames, roof trusses, purlins and girts, fascias, floor framing, trestles, bench frames, gates, fences, cattle grids, television towers, scaffolds, tank stands, stands, stock crushes and pens, feed and crop drying fames, ladders, hand rails, shelving frames, machinery bases, mullions and lintels, exposed beams and columns

Specification
BlueScope Lysaght cold formed steel channels and angles are available either zinc coated or uncoated in base metal thicknesses (BMT) of 1.0 mm, 1.6 mm, 2.5 mm and 3.0 mm depending on section type. The materials used are zinc coated steel to AS 1397-2001 G300-Z275 (300 MPa minimum yield stress, 275g/m2 minimum average coating mass) and uncoated steel to AS/NZS 1594-2002 HA300 (300 MPa minimum yield stress).
In addition, subject to minimum quantity order, BlueScope Lysaght cold formed steel channels and angles can be produced from higher yield stress uncoated and zinc coated steels to meet more demanding design requirements.
