Eaves Beams are available in an optimised section range of 200, 240 and 300mm deep with multiple gauge choices to suit span conditions. All eaves beams can be supplied with a positive or negative angle to the top flange.

Negative angles are used in mono-pitch roof construction to offer building stability at the eaves.

Channel sections also range from 140-300mm deep and are used in portal frames as side cladding rails, panel joint rail configurations, door trimmers and mezzanine floor systems. Load tables are available on request.
