Steel Stair Riser 2 Step Stringer for 20in Deck Height - Heavy Duty

In this review the Steel Stair Riser 2 Step Stringer is measured by practicality and durability for simple outdoor steps. This set of two predrilled metal stringers is aimed at homeowners and builders who need a compact, reliable stair solution for a deck about 20in high; the single biggest reason to buy is the heavy-duty construction and 500 lb load capacity that outlasts typical wood stringers. The reviewer found the powder-coated finish and included fasteners valuable, while noting a few installation caveats to plan for.

Key Features

• Premium Material: High-quality steel with a corrosion-resistant powder-coated black finish provides long-term protection outdoors and reduces maintenance.
• Complete Installation Kit: The package includes two 2-step stringers plus set screws for concrete and screws for attaching wooden treads so projects start with most hardware on hand.
• Easy to Install: Predrilled holes simplify alignment and attachment, making the stringers faster to mount than fully custom-fabricated options when holes line up.
• Heavy-Duty Capacity: Engineered to support up to 500 lbs, the stringers offer strong, stable support for foot traffic and occasional heavy loads.
• Versatile Outdoor Use: The compact two-step design is well suited for decks, patios, and garden pathways where a short, sturdy stair is required.

Who It's For

These steel stair stringers are best for DIY homeowners, deck builders, and landscapers who need a low-profile, durable two-step solution for a deck that is roughly 20in high. The product suits projects where rust resistance and a neat black finish matter, and where predrilled holes and included fasteners will save time on site.

Those who should look elsewhere include remodelers needing custom rise/run dimensions beyond the 2-step fixed layout, and installers who require longer or adjustable mounting bolts because some customers reported screw length and bolt-hole alignment issues that may require supplemental hardware.

Pros & Cons

Cons

• Screw length and bolt-hole alignment have been reported as problematic, so extra fasteners or adjustments may be required.
