Steel Stairs and Railing Design

Code-Compliant Stair and Railing Engineering That Passes Inspection the First Time

Stairs and railings look simple. They aren’t. They carry real, code-mandated loads, they’re held to some of the strictest requirements in the building code, and they get scrutinized harder by inspectors than almost anything else in the structure — because when a guardrail fails, someone gets hurt. A stair that’s a half-inch out of tolerance or a railing that can’t prove its load rating doesn’t just fail inspection; it holds up occupancy on the entire building. At Lam-Wood Systems Inc., our licensed Professional Engineers design steel stairs and railing systems that satisfy the code, integrate with the structure, and give the fabricator drawings they can build from — so this deceptively tricky scope doesn’t become the thing standing between you and a certificate of occupancy.

The challenge with stairs and railings is that they sit at the intersection of structural engineering, strict life-safety code, and fabrication detail — and they have to satisfy all three at once. The structure has to carry the loads. The design has to meet IBC and OSHA requirements down to the dimension. And the whole thing has to be detailed precisely enough for a shop to fabricate and a crew to install without rework. Miss on any one of those and the system comes back. We engineer all three together, so it doesn’t.

What We Engineer

Stair and railing work spans a range of types and settings, each with its own load cases and code demands. Our team handles the full scope, engineered to the specific requirements of your building and its occupancy.

Egress and Commercial Stairs. The stairs people use to get out of a building safely are governed by the strictest provisions in the code. We design steel egress stairs — stringers, treads, landings, and supports — engineered for code-mandated live loads and detailed to fit the architecture and tie cleanly into the structure.

Industrial Stairs and Platforms. Plants, facilities, and equipment access bring OSHA into the picture alongside the building code. We engineer industrial stairs, ship’s ladders, catwalks, and access platforms that meet OSHA load and dimensional requirements and stand up to heavy daily use.

Guardrails and Handrails. Railings have to resist specific concentrated and distributed loads the code spells out exactly — and prove it. We design guardrail and handrail systems, their posts, and their connections to carry those mandated loads and survive the inspector’s scrutiny, whether the look is heavy industrial or architecturally exposed.

Feature and Architectural Stairs. When a stair is meant to be seen — open risers, mono-stringers, floating treads, glass-railing infill — the engineering gets harder precisely because the structure has to disappear into the design. We engineer architectural stairs that hit the aesthetic the architect wants while quietly carrying every load the code demands.

Code Is the Whole Game Here

More than almost any other structural scope, stairs and railings are won or lost on code compliance. The loads are prescriptive, the dimensions are prescriptive, and inspectors check them closely because these are the elements the public physically touches and leans on every day. A guardrail that can’t demonstrate it resists the required load, a stair riser that varies more than code allows, a handrail at the wrong height — any one of these fails, and the fix is expensive because the steel is already fabricated. We engineer to IBC and OSHA requirements from the start, with the load paths documented and the dimensions held, so the system that gets built is the system that passes.

That compliance is backed by the seal of a licensed Professional Engineer on every design — which is exactly what reviewers and building officials want to see on life-safety elements like these. You get engineering that’s defensible on paper and correct in the field.

Detailed to Fabricate and Install

A stair or railing design only earns its keep when the shop can build it and the crew can install it without a running list of questions. Because stairs involve so many precise, interdependent dimensions — riser heights that have to stay equal, landings that have to land, connections that have to hit the surrounding structure exactly — sloppy detailing here turns into expensive field rework fast. We detail our stair and railing designs with the dimensions, connections, and clearances a fabricator needs to build accurately and an erector needs to install clean.

That fabrication-minded approach comes from years of working with custom steel hardware and detailing how steel assemblies actually go together. The connections that anchor a stair to the structure or tie a guardrail post to a slab edge draw on the same expertise behind our Steel Connection Design service — because a stair is only as solid as the connections holding it to the building. And when something needs to be resolved in the field during installation, our Construction Support Engineering team is ready to turn a stamped answer around fast.

Who We Work With

Steel fabricators and stair shops rely on us for stair and railing designs that are code-compliant, sealed, and detailed for production — so they can bid with confidence and fabricate without guesswork. General contractors bring us in to keep this often-overlooked scope from becoming a late-stage occupancy holdup. Architects partner with us when a feature stair has to look the part without compromising on safety. Whoever owns the stair package, we make sure it passes.

Engineer Your Stairs and Railings With Lam-Wood

Stairs and railings are too code-critical and too inspection-sensitive to leave to guesswork — and too important to the occupancy schedule to get wrong. With licensed Professional Engineers, rigorous IBC and OSHA compliance, and fabrication-ready detailing, Lam-Wood Systems Inc. delivers stair and railing engineering that passes the first time. This is part of our full structural engineering practice. Contact our engineering team or call 303-458-1736 to get your stairs and railings engineered right.
