Railing Dynamics has added Avalon Aluminum Railings to its lineup. The preassembled, powder-coated, rust-proof railing panels are available with three top rail styles, in three colors—white, gloss black, and satin black—and in 42- and 36-inch heights. Angled assemblies are available for stairs. “Securatec” strips keep balusters rattle-free and eliminate the need for spacers and fasteners. In weather-resistance testing, the railings withstood more than 8,000 hours of accelerated salt-spray exposure, the company said. The railing meets most commercial and residential codes.
