Radiance Deck Railing is manufactured by Timbertech in Wilmington Ohio. They are a vinyl coated composite rail, that means they have thick composite walls, for strength, that are covered with a vinyl coating for long lasting strength and beauty. They come standard with larger post sleeves and a thick railing profile for a very solid finished look. Radiance railings are available in White, Black, Mountain Cedar, Kona, Brownstone, and Slate Gray colors. We can mix and match any colors, so if you wanted to do black railings and posts with white spindles, we can do that. Also black aluminum spindles in 3/4" round or square are available for any color railing. Radiance rails can cost from 60% to over 100% more than Vinyl rails depending on the size and shape of your deck and the number of posts. Radiance Rails are a great option for your deck if you want the advantages of a vinyl rail but you want something different than the average Vinyl rail.
