Galvanised Steel Sub-Frame

Our steel sub-frame system can and has been used for many applications but its primarily design function is as a long life decking sub-frame; If you are going to fit a polymer or composite deck board, why not fit a sub-frame that is also designed to last.


Geoplas galvanised steel beams are complemented by a range of zinc plasted steel brackets that simply slide onto the beam ends before being fixed in place by self-drilling tech screws. Geoplas will be happy to assist with your sub-frame design and help confirm its load bearing performance. The Geoplas galvanised steel sub-frame system replaces timber sub-frame materials and offers longevity, ease of fitting, strength and the benefits of a product that does not move or twist with age.
