Century’s aluminum picket railing system offers contractors measurable advantages in installation efficiency, weather resistance, and 20-year warranty coverage with pre-punched components and concealed welds.
The 5/8 inch (0.625”) picket size delivers a narrow-profile aesthetic that works across residential deck projects. Pre-punched rails eliminate the need for spacers — saving installation time and reducing the chance of spacing errors that plague traditional systems.
Installation Efficiency and Specifications
Century’s concealed welds with continuous bottom rail design create a cleaner look while speeding assembly. No visible welds means no rough edges to file down or touch up.

The quick-install system designed for both DIYers and professionals doesn’t mean compromised strength. Heavy-duty contractor-approved build handles Montana’s temperature swings and snow loads.
Weather Performance and Durability
High-strength aluminum construction won’t rust like steel railings that fail at weld points after a few Montana winters. Premium UV and weather-resistant powder-coat finish fights the intense high-altitude sun exposure that fades lesser coatings.
Century backs their material and manufacturing with a 20-year limited warranty. The powder coat finish carries a 5-year warranty (reduced to 1 year in salt-prone locations). That’s confidence in cold-weather performance.
Available finishes include Gloss White, Textured Matte Black, Textured Lakeside Copper, and Custom Colors. The textured options hide scratches better than gloss — practical for high-traffic decks.
Compared to wrought iron: lighter weight, more durable, lower total cost, rust-free, and significantly lower maintenance requirements. No annual painting. No rust bleeding onto deck boards. Radius-milled picket edges for a smooth touch eliminate the sharp corners that catch clothing.
