CORRUGATED ROOFING
Traditional & versatile
- Classic curved profile that works with traditional and contemporary buildings
- Lightweight and widely used for residential roofing and wall cladding
- Can suit straight or curved applications when specified correctly
- Available in COLORBOND® and ZINCALUME® steel options
Consider: a 5° minimum roof pitch means it is not the first choice for very low-pitch roof designs.
TRIMDEK® ROOFING
Clean lines & low pitch
- Bold ribs create a neat, modern and strongly linear appearance
- Suitable for roofing and walling across residential and commercial projects
- Designed for strong spanning performance and wider support spacings where engineering permits
- Available in COLORBOND® and ZINCALUME® steel options
Consider: the squarer rib profile gives a noticeably different look from traditional corrugated roofing.
