RDI Rail

What RDI Rail does

RDI Railing is a US-based manufacturer of low-maintenance outdoor railing systems marketed under an Oldcastle APG Outdoor brand. The company designs and distributes railing for residential decks, porches, patios, balconies, docks, and stairs across four material categories — composite, vinyl, aluminum, and steel — through a portfolio of ten branded product lines (Transform, Bella Premier, Fusion, Overlook, Avalon, Elevation Rail, Privacy Rail, Endurance Original Rail, Finyl Line, and MetalWorks Excalibur) plus accessories including LED lighting, ADA handrails, matching gate kits, and Freestyle complementary accents. The technology backbone is a set of 20+ patented innovations spanning structural materials and installation systems, including Composicore (a wood-fiber-free composite substrate), AlumiCast (an aluminum-mimicking composite cast technology), ProLock (inside-out locking strips), ClickConnect (vinyl infill locking), and OneTen (a built-in cable tensioning system claimed to deliver 38% faster installation than leading competitors).

The company operates a hybrid go-to-market motion: product-led content marketing and a Yardzen AI design-tool integration target homeowners at the top of the funnel, while a dedicated sales-led motion serves railing installers, architects/specifiers, and multifamily builders with AIA-accredited continuing education, BIM/specification files, contractor rewards, and first-time-user rebates. Distribution is anchored by a nationwide network of 1,903 dealers and 1,808 retailers spanning 3,711+ locations and a Find-an-Installer locator connecting customers with 1,010+ certified installers; revenue is generated through one-time hardware sales (with mid-range pricing by material tier) and ancillary professional services and training. RDI serves US and Canadian markets with localized French and Spanish experiences, and is integrated into Oldcastle APG Outdoor's broader family of outdoor construction brands (Belgard, Catalyst, Sakrete, Techniseal, etc.) for cross-brand contractor rewards.
