Signature Monobeam Straight Stair Design
Built for Minimalism, Designed for Strength
The Custom Iron Standard Monobeam is one of our most requested styles for custom-designed straight staircases in the USA. It’s defined by a single center beam that gives the stair a floating appearance—sleek, minimal, and impressively strong. We’ve incorporated thoughtful adjustability into the design, giving you flexibility during installation without sacrificing performance or aesthetics.
This design is ideal for:
- Open floor plans
- Modern industrial homes
- Office environments and commercial spaces
- Retrofit projects where clean lines matter
Our Monobeam stairs are available in popular finishes like black, white, and custom powder-coated options.

L-Shaped Staircases
A Seamless Blend of Style and Function
When you want a staircase that makes a strong architectural statement while also maximizing practicality, L-shaped staircases are a perfect choice. Known for their 90-degree turn, these staircases not only create a striking focal point but also improve flow and accessibility in a wide range of spaces. At Custom Iron, we bring decades of experience to designing and fabricating L-shaped staircases that combine strength, versatility, and custom craftsmanship.
Why Choose L-Shaped Staircases?
L-shaped staircases introduce an intentional change in direction that can add both safety and design appeal. The landing in an L-shaped layout serves as a natural pause, reducing fall risk and creating a smoother transition between levels. This design can also maximize floor plans for homes and businesses with limited square footage by fitting neatly into corners.
In addition to their functional benefits, L-shaped staircases offer design flexibility. They can be positioned to complement open floor plans, anchor entryways with dramatic appeal, or discreetly integrate into tight architectural layouts. Whether your project leans modern, traditional, or industrial, this staircase style adapts beautifully.
Custom Fabrication for Every Project
At Custom Iron, every staircase is built to order in our Zumbrota, Minnesota, production facility. Our team of skilled fabricators works with you to select materials, finishes, and railing designs that match your vision. Unlike mass-produced kits, our staircases are never one-size-fits-all—they are carefully crafted to your specifications.
From powder-coated steel frames for durability to custom wood or composite treads for warmth and texture, the options are endless. We collaborate with homeowners, architects, and builders alike to ensure the final result is as functional as beautiful.
Residential and Commercial Applications
L-shaped staircases are ideal for both residential and commercial environments. In a home, they can act as a centerpiece in a grand foyer, a stylish solution for split-level layouts, or a space-saving addition in compact interiors. For commercial projects, they provide both durability and visual impact, handling heavy traffic while contributing to the overall architectural character of a building.
Exterior applications are also possible, with weather-resistant finishes and railing systems that allow your staircase to perform year after year in outdoor conditions. Whatever the environment, L-shaped staircases deliver a balance of strength, safety, and design appeal.
Versatility in Design
One of the defining advantages of L-shaped staircases is their versatility. They can be open and airy with minimalist railings or bold and industrial with heavier materials. They can also incorporate landings of various sizes to meet accessibility requirements or simply enhance the overall design aesthetic.
Because of their unique geometry, L-shaped staircases naturally divide spaces and create subtle architectural transitions. This makes them a popular choice in multi-use spaces, lofts, or homes where you want both form and function without compromise.
Our Commitment to Craftsmanship
Every staircase we create reflects our dedication to innovation, quality, and customer satisfaction. With decades of industry leadership, Custom Iron has perfected the process of designing L-shaped staircases that are straightforward to install, durable in performance, and timeless in appearance. Our hands-on approach ensures that you receive not just a staircase, but a centerpiece that enhances the way you experience your space.
