QuickStep aluminum stair stringers deliver 50% faster installation than wood with 4,400 lbs capacity per step at 36” spacing. For contractors tired of cutting custom stringers and homeowners who want stairs that won’t rot in Montana’s freeze-thaw cycles, these pre-configured aluminum systems solve real problems.
The trade-off? Higher upfront cost than pressure-treated stringers. Worth it for anyone building decks that need to last decades without maintenance headaches.
Installation Speed That Actually Matters
Cut-less installation with pre-configured steps changes the stair-building game. Traditional wood stringers demand precise layout, multiple cuts per stringer, and perfect execution. QuickStep’s 7.5” rise x 10.5” run pre-engineered spacing eliminates the math and measuring errors.
Undermount stringers to deck framing with structural bolts, level them out, secure with recommended fasteners, then attach QuickStep treads. The undermount system hides fasteners for clean sight lines. No visible screws poking through treads.
Installation time reduced by half compared to traditional wood stairs. That’s not marketing fluff — it’s contractor feedback from the field. Time savings come from eliminating layout errors, saw cuts, and the back-and-forth of custom fitting.
Structural Performance Built for Real Loads
4,400 lbs per step capacity when used as complete system at 36” spacing exceeds anything achievable with dimensional lumber. Wood stringers typically handle ~2,500 lbs under similar conditions.
That extra capacity matters in Montana. Snow accumulation on deck stairs, multiple people carrying furniture, construction crews hauling materials — real-world loads that push limits. The high-strength aluminum alloy construction doesn’t degrade over time like wood does.
| Specification | QuickStep Value |
|---|---|
| Load Capacity | 4,400 lbs per step at 36” spacing |
| Rise per Step | 7.5 inches |
| Run per Step | 10.5 inches |
| Material | High-strength, never-rust aluminum alloy (100% pure) |
| Finish | Premium UV-cured powder coat |
| Packaging | Sold in pairs (2 stringers per package) |
Meets or exceeds residential deck/stair building code requirements across the U.S. and Canada. Approved for up to 12 storey use in Multi-Family applications demonstrates the system’s structural integrity beyond typical residential needs.
Complete System Approach
QuickStep works as an integrated system. 1 to 9 step increments available cover most residential applications. Need longer runs? Connector kit handles up to 14 steps, eliminating the need for landings.
Compatible components include:
- QuickStep 48” L x 11” D x 1.5” H StoneWood treads in Slate Grey, Natural Cedar
- Aluminum riser covers (7-3/8” W x 3” D x 48” L)
- QuickStep Connector Kit
- Compatible with all Regal Railing System components
The S-Glass fiber treads feature flameproof and waterproof properties with no twisting, expanding, or shrinking. Quick undermount attaching hides fasteners on treads too.
Color options — White, Black, Yard Bronze — match across stringers, rails, and accessories for cohesive deck aesthetics.
Montana-Ready Durability
100% rust-proof aluminum handles Montana’s moisture extremes. Spring snowmelt saturating ground contact areas, summer thunderstorms, fall freeze-thaw cycling — aluminum shrugs it off. UV-cured powder coat finish (meets AMA-2603 standards) resists fading at elevation where UV exposure runs 25% higher than sea level.
20-year limited warranty covering material and finish defects including rust, fading, and structural failure under normal use backs up the durability claims. Compare that to pressure-treated stringers needing replacement every 15-20 years in freeze-thaw country.
No painting or staining required eliminates the annual maintenance trap of wood stairs. Montana’s short staining season (June through September) means wood stairs often go unmaintained. QuickStep sidesteps that problem entirely.
Real-World Applications
Contractors emphasize ease of installation, durability, and code compliance, particularly suitable for contemporary decks in regions with harsh weather. Primary uses include:
- Residential decks and patios
- Commercial outdoor decking
- Pool decks
- Cottage, cabin, or vacation home stairs
Some users report success with interior stairs, though the system targets exterior applications.
Installation Requirements
Tools needed:
- Drill/Impact driver
- Measuring tape
- Level
- Socket set or wrench
- Hacksaw or metal saw for connector kit modifications
Fasteners (sold separately):
- Regal Quick Step 10 x 1-1/4” self-drilling screws (typically 24pk)
- Regal Structural Bolt 3/8” x 2-3/4” (typically 4pk)
Proper layout and adherence to local building codes ensures safety and compliance. The fixed rise and run dimensions mean accurate total rise measurement before ordering matters.
The Bottom Line
QuickStep aluminum stringers cost more upfront than pressure-treated lumber. No dancing around that reality. But contractors billing by the hour save money through 50% faster installation. Homeowners save money by never buying stain, never rebuilding rotted stringers, never dealing with warped steps.
The 4,400 lbs capacity provides genuine safety margin. The rust-proof aluminum with UV-cured finish survives Montana weather. The pre-engineered system eliminates layout errors that plague custom-cut wood stringers.
For deck stairs that need to perform without drama for decades, QuickStep delivers measurable advantages over traditional framing. Customers praise excellent value, stylish appearance, and ease of use. The only real weakness? Limited availability in some colors/sizes means ordering ahead during peak season.
Frequently Asked Questions
What’s the actual weight capacity of QuickStep stringers?
4,400 lbs per step when used as a complete system with treads at 36” spacing. That’s tested capacity, not theoretical. Exceeds residential building codes by a wide margin.
How much time does the system really save?
Up to 50% faster installation compared to wood. Installation time reduced by half according to contractor feedback. Time savings come from cut-less, pre-configured steps that eliminate measuring, marking, and cutting stringers.
Can these handle Montana winters?
Absolutely. 100% rust-proof aluminum won’t corrode from road salt or freeze-thaw cycling. UV-cured powder coat finish resists fading despite high-altitude sun exposure. 20-year warranty covers rust, fading, and structural failure.
What stair configurations are available?
1 to 9 step increments with fixed dimensions of 7.5” rise x 10.5” run. Need longer runs? Connector kit handles up to 14 steps without requiring a landing.
Do the stringers come with fasteners?
No. Fasteners sold separately. You’ll need Regal Quick Step 10 x 1-1/4” self-drilling screws and Regal Structural Bolt 3/8” x 2-3/4” for proper installation.
