Duradek is continually researching, developing and testing new products and application techniques. Durarail Rail and Fence Systems The strength of a rail or fence system is in the posts and the framework. The stronger the structure, the wider the spans between the posts. This provides for better visual appearance and view. The heavy wall thicknesses of the aluminum and the intricately designed extrusion combined with the fastening system gives Durarail the exceptional spans it has achieved. They are among the widest in the industry. The Durarail polyester material (TGIC) is UV resistant, will not peel, flake or blister and as it ages, can be buffed back to like-new condition with a cut polish. Durarail Rail and Fence Systems are available in nine standard colors. Over 180 custom colors can be produced to match any exterior design features.
