Trussed Rafters

Trussed rafters stand out as a sophisticated and highly-engineered product, with superior fabrication underpinned by high production standards. They are more flexible and more cost effective than many other methods of roof construction.

Metal Web Joists

With metal-web joists, not only can the floor span further than with conventional joisting methods, but the speed of installation both of the floor itself and the subsequent services in the floor zone is much faster.
 

Chain of Custody

Companies are independently assessed against “chain of custody” standards to demonstrate they can supply wood productsderived from sustainable forests.Two frameworks oversee  development of forest certification, these are Forest Stewardship Council (FSC),  Programme for Endorsement of Forest Certification (PEFC)
