We were engaged by our client to install a free standing steel structure incorporating a Helioscreen HS12 retractable roof. the client did not want any of the roof to attach to the house as it was rendered polystyrene. we had an engineered post and back beam fabricated to be self supporting in conjunction with the Helioscreen HS12. They also wanted a chunky timber post on the posts to tie in with their rustic look. The system was designed to have a 2 degree side fall and  was finished off with integrated LED lighting and Duratec Powdercoating
