Century Picket Series Aluminum Railing

Decking & Railing Century

Century’s Picket Series delivers two distinct aluminum railing systems — narrow 5/8” pickets for traditional aesthetics and wide 1.5” pickets for contemporary looks. Both options feature pre-punched rails that eliminate spacers, speeding installation for contractors who value efficiency over fussing with individual picket spacing.

The Aluminum Advantage in Montana

High-strength aluminum construction means zero rust concerns, even with Montana’s temperature swings from -30°F to 100°F. The UV and weather-resistant powder-coat finish handles intense mountain sun at elevation without the annual maintenance wood demands.

Pre-punched rails eliminate the need for spacers — a feature contractors appreciate when building multiple deck sections. No measuring, no spacing jigs, no guesswork. Rails arrive ready to accept pickets at proper intervals.

Warranty Reality Check

Century backs their aluminum with a 20-year limited warranty on materials and manufacturing defects. The powder coat finish carries a 5-year warranty, but here’s the catch — it drops to 1 year in salt-prone locations. Not a concern for inland Montana, but lakefront properties near road salt spray should take note.

Warranty applies to original consumer purchaser for single-family or duplex residential units in the U.S. or Canada. Commercial projects need different coverage discussions.

Installation Advantages

The quick-install system designed for both DIYers and professionals uses concealed welds with continuous bottom rail design. Translation: no visible fasteners or welds breaking up the clean lines.

Concealed weld system simplifies assembly and provides a seamless look while maintaining structural integrity. Posts accept rails with quick-snap components with pre-welded post brackets — no drilling, no guessing on bracket placement.

Who Should Consider Century

Contractors report straightforward installation process as advertised and describe it as a ‘great product’ with high-quality service from distributors. The dual picket size options give flexibility other aluminum systems lack — match traditional cedar railings with 5/8” or go modern with 1.5” wide pickets.

Best suited for:

  • Contractors wanting faster installation than traditional spacing systems
  • Projects requiring specific aesthetic matches (narrow vs. wide pickets)
  • Montana decks where rust-free performance matters more than lowest price
  • Homeowners seeking modern, sleek design and durability

Skip it for:

  • Budget builds where vinyl suffices
  • Horizontal cable or glass railing aesthetics
  • Commercial projects needing different warranty terms

FAQ

Q: What’s the actual difference between 5/8” and 1.5” pickets beyond width?

The 5/8” offers a ‘Narrow’ aesthetic compared to the ‘Wide’ 1.5” picket option. Narrow pickets create a more traditional, refined look similar to classic wrought iron. Wide pickets deliver a bolder, more contemporary appearance with fewer vertical lines.

Q: How do pre-punched rails speed up installation?

Pre-punched rails eliminate the need for spacers. Traditional systems require spacing each picket individually — tedious work that compounds errors. Pre-punched rails arrive with holes at exact intervals. Pickets drop in, align automatically, done.

Q: Does the warranty cover Montana’s extreme temperature swings?

The 20-year limited warranty covers material and manufacturing defects regardless of temperature. The UV and weather-resistant powder-coat finish specifically addresses sun and weather exposure. The 5-year finish warranty (not the 1-year salt-prone reduction) applies throughout Montana.

Q: What post options work with this system?

Century’s system accepts both 2.5 inch square aluminum posts and 4 inch square aluminum posts. The 2.5” posts suit standard residential decks. The 4” posts provide a more substantial look or meet code requirements for taller installations.
