Dimensions of a Plas-Pro to DuoSpan Screw A Plas-Pro to DuoSpan 50mm screw measure 5mm x 50mm. They have also been designed and manufactured by industry experts. This is to provide strength and stability to your decking subframe and structure. Made from robust aluminium, they comply with Eurocode1: Actions on Structures (BS EN 1991-1-1). What colours are the 50mm Duospan Screws available in? We currently supply the Plas-Pro to DuoSpan 50mm Screw in a dark blue colour. This bright colour helps you spot where each fixture is fitted and will be neatly hidden within the subframe as your decking is installed. What fittings do I need for Millboard's Plas-Pro subframes? With all of Millboard's products and accessories, we recommend using their Durafix. and Durospan screws to securely and correctly fit your cladding. Their subframes, decking, cladding, and starter trims all come with pre-drilled holes for accuracy and perfectly fit their Durafix screw range. The screws themselves are made from sturdy stainless steel, built to last all weather conditions with long-lasting results.
