RIBLINE

Ribline is a popular choice for residential roofing, farm buildings and light industrial applications, making this low rib profile an alternative to Corrugate. Ribline is warranted for coating performance*, corrosion resistance and substrate integrity. Ribline is an attractive and cost effective profile for most roofing and cladding applications.  

*Excluding GALVSTEEL®

Our Ribline profile is available in a wide selection of materials with Alsynite topglass available to match.

Taranaki Steelformers have recently introduced Ribline Smooth to their product line. Ribline Smooth is an attractive wall cladding alternative, being run without swages brings a smooth, continuous finish to each tray.

Maximum Spans
