Metal Stair Treads & Landings for Lake Tahoe Hillside Homes

Hillside properties around Lake Tahoe, Incline Village, and Truckee almost always involve exterior stairs. Whether it is a staircase from street level down to the front door, a set of steps connecting decks on a multi-level build, or a utility access stairway to a lakeside dock, the treads take a beating. Wood rots. Concrete cracks and heaves. Metal treads, fabricated correctly, hold up for decades in the Sierra Nevada climate without splitting, warping, or becoming a liability when conditions get icy.

We fabricate custom metal stair treads and landings at our Reno shop for residential and commercial projects throughout Northern Nevada and the Tahoe basin. Here is what goes into getting them right.

Why Metal Treads for Mountain Exterior Stairs

The argument for metal treads in the mountains is straightforward. Exterior stairs at elevation deal with heavy snow loads, freeze-thaw cycles, standing water, UV exposure, and foot traffic with boots, ski gear, and ice cleats. Wood treads in Truckee and Tahoe often need replacement within eight to twelve years. Composite decking fares better but still gets slippery when wet or icy.

Metal treads resist all of those conditions. Steel and aluminum do not rot, split, or absorb moisture. They can be textured or coated for grip, and they drain snow and water instead of trapping it. For hillside homes where the stairway is long and exposed, metal is the practical long-term choice.

Diamond Plate vs. Bar Grating vs. Perforated Patterns

The three most common tread styles each have their place:

• Diamond plate (checker plate) is solid steel or aluminum with a raised diamond pattern. It provides good traction, is easy to fabricate and weld, and works well for enclosed stairways or where you want a solid surface underfoot. Snow sits on diamond plate, so it is best used with a roof overhead or in lower-snow areas like Reno and Sparks.
• Bar grating uses welded or press-locked bars with open spacing that lets snow, water, and debris fall through. This is the go-to for exterior stairs in heavy-snow areas like Incline Village and Donner Summit. Grating treads are self-clearing and reduce the ice buildup that makes solid treads dangerous.
• Perforated plate sits between the two. Small holes punched in flat plate let water drain while still providing a mostly solid surface. It works well for deck stairs and balcony access where some drainage is needed but you want a cleaner look than bar grating.

We help clients choose based on the specific location, snow exposure, and aesthetic of the project. A lakefront home in Crystal Bay has different needs than a commercial building stairway in Carson City.

Snow and Ice Drainage Considerations

In the Tahoe basin, where annual snowfall regularly exceeds 200 inches at lake level and far more at ridge lines, stair tread design has to account for accumulation and drainage. Solid treads trap snow that compacts into ice. Open grating treads let snow fall through, but the supporting stringers and landings still need to handle the weight.

We design treads with slight pitch so meltwater runs off rather than pooling. Landing plates get the same treatment. For long stairways on steep lots in Incline Village or the West Shore, we also factor in the structural load of snow sitting on landings and intermediate platforms. The framing has to carry the weight even when the treads themselves are draining properly.

Steel vs. Aluminum for Stair Treads

Both materials work. The choice depends on the application.

Steel is stronger per dollar. It is the standard for structural stair systems where the treads are welded to steel stringers. Hot-rolled steel treads are robust and can be hot-dip galvanized or powder coated for corrosion protection. For hillside access stairs that span 30, 40, or 50 feet of elevation change, steel is the practical choice because it handles the structural loads without overbuilding.

Aluminum weighs roughly one-third of steel. It does not rust, which matters in wet environments where a coating might get scratched or worn. Aluminum treads are common on dock access stairs around Lake Tahoe and for lightweight deck stair replacements in Washoe County. The tradeoff is cost. Aluminum material is more expensive, and welding aluminum requires TIG capability and more shop time.

Anti-Slip Coatings and Textures

Texture alone does not always cut it in icy conditions. We offer several anti-slip options for treads that will see winter use:

• Grip-Strut or safety grating with serrated bearing bars that bite into boot soles
• Abrasive nosing strips welded or bolted to the leading edge of each tread
• Non-skid coatings applied over powder coat with embedded aluminum oxide grit
• Raised knurled patterns rolled or pressed into the tread surface

For stairs that get regular foot traffic in Northern Nevada winters, we typically recommend either serrated grating or abrasive nosings. They are maintenance-free and do not wear out the way adhesive grip tape does.

Code Requirements for Stair Dimensions and Railing Integration

Exterior stairs in Washoe County, Placer County, and the Tahoe Regional Planning Agency jurisdiction all follow the IRC and local amendments. The basics: minimum tread depth of 10 inches, maximum riser height of 7-3/4 inches, and uniform dimensions throughout the run. Landings are required at the top and bottom and at any point where the stair changes direction.

Guardrails are required on any stair with a total rise of more than 30 inches, and handrails are required on at least one side of any stairway with four or more risers. Baluster spacing cannot exceed four inches. We fabricate treads and rails as integrated systems so the dimensions, connections, and fastening all line up without field modifications. The stringer-to-tread connection, the rail post base plates, and the landing transitions are all worked out in the shop before anything ships to the job site.

Hillside Home Access Stairs in Tahoe and Incline Village

Some of the most demanding stair projects in our area are the long hillside access stairs at lakefront and ridge-top properties. A home on Lakeshore Boulevard in Incline Village might need 80 steps from the road down to the entry. A cabin above Donner Lake might need a switchback stairway down a 45-degree slope to reach the water.

These are structural steel projects. The stringers are often heavy tube or channel steel anchored to concrete piers at intervals along the slope. The treads and landings have to handle snow loads, occupant loads, and the lateral forces from wind and soil movement on steep terrain. We engineer these systems to be buildable in sections that can be transported and assembled on grade, since crane access on Sierra Nevada hillsides is often limited or impossible.

Deck and Balcony Stair Replacements

Not every stair project is a major hillside build. A large portion of our tread work is straightforward replacements: pulling rotted wood treads off an existing deck stairway and replacing them with metal. In neighborhoods throughout Reno, Sparks, and Carson City, older homes have deck stairs that have deteriorated after years of sun and weather exposure. Swapping in metal treads with the original stringers still intact is often the most cost-effective repair.

We measure the existing stringer spacing, nosing overhang, and fastener locations, then fabricate drop-in treads that bolt to the existing framework. For decks where the stringers are also failing, we build the full stair assembly in steel or aluminum and deliver it ready to install.
