PVC Rail, Frame, Tubing & Pipe Stiffeners and Reinforcements

Stiffeners made for PVC extrusions are commonly roll formed as U-Channels, C-Channels, Angles, and other unusually shaped profiles to match the opening in the extrusion. For many years, Johnson Bros. has manufactured stiffeners that are taylor made for a particular slide in fit desired by the customer. This fit is affected by PVC tolerances more than accurate Roll Forming tolerances. Many standard tooling styles exist for this industry. Custom styles are available as well. Pre-coated metals such as galvanized, galvannealled and aluminized, are used for corrosion protection. Stainless steel, Aluminum, and pre-coated high strength steel may also be used. Parts can be accurately cut inline to a desired length as well as other inline fabrications supplied, such as, slots, holes, notches, and end fabricating. An accurate, one stage, forming process, is commonplace. Customers are requested to provide extrusion samples, with tolerances, for most accurate taylor made fitting of the stiffener inside the extrusion for our quality control and engineering department. Our engineering department can provide prints of the stiffener in it`s final form for optimal fit characteristics. Thicknesses of stiffeners can range from .135" through .030" thick. Accurately cut lengths can be from 3" long through 40 feet long. Extra care is taken in packaging to prevent damage.

Parts are produced to order and stock reserve only kept for large blanket order shipping releases. Existing samples may or may not be available. Prototypes for large orders are feasible.
