Magna Rib®

Features

Excellent spanning capacity. Excellent rigidity and structural performance. Excellent drainage capacity. Deep profile creates strong shadow line.

Applications

May be specified as single skin, thermally or acoustically rated roof and/or wall cladding.

Applications include large-scale, long-span industrial structures, including power stations, wide body aircraft hangars, and major warehouse facilities.

Orientation & Accessories

Can be installed as a vertical, horizontal or diagonal system to walls. Can be mitred but not curved. Supplied with a range of accessories as required.

Notes: Allowable loads limited by stress of 180 MPa, or deflection of L/180.
* Denotes where values determined by stress. n/r Not Recommended. Shaded area indicates where standard maximum length precludes use of profile.
