A well-designed staircase can entirely change the character of an interior. The proportions of the stringer, tread layout, railing style, and surrounding space all need to work together – especially in open-concept homes where the staircase is one of the first architectural features you see.
For Ajax homeowners planning a renovation or new build, we can develop the staircase around the style of the property rather than working from a standard design. A slim mono-stringer can create a lighter, more open appearance, while double steel stringers provide a strong architectural look for larger staircases. Glass railings can keep sightliness open, while custom metal railings can add more definition to the design.
We consider the practical details from the beginning, including available space, stair configuration, landings, headroom, railing integration, and how the finished staircase will connect with the surrounding floors and interior. This approach allows us to create a staircase that feels like part of the architecture- not something added afterward.
Installing a custom staircase requires careful planning long before the finished stairs arrive on site. Accurate measurements, structural conditions, floor heights, openings, and connection points all need to be confirmed, so the fabricated staircase fits the space properly.
For projects in Ajax, our process begins with a site assessment. The steel components are then fabricated to the project specifications in our workshop. Before installation, we coordinate site access and timing with the homeowner, builder, or general contractor to help the installation move efficiently and minimize disruption to other work.
On site, our team positions and secures the staircase, checks alignment and stability, and prepares the system for remaining components such as treads, handrails, metal railings, or glass railings. Particular attention is given to connection points and finishing details, so the completed staircase has a clean, professionally installed appearance.

Custom metal railings are a practical way to add safety and architectural detail without overwhelming the surrounding space. At Modern Stairs Plus, we fabricate railing systems for interior and exterior applications, from clean contemporary designs to more decorative metalwork.
Depending on the project, railings can be fabricated from steel, wrought iron, stainless-steel and finished suiting the environment and architectural style. Options include vertical-picket railings, horizontal designs where permitted, custom handrails, guardrails, and metal frames designed to work with glass panels.
For renovations and new construction projects in Ajax, we can coordinate the railing design with the staircase, landing, balcony, or other architectural features. Each system is measured and fabricated for the individual project, with careful attention to secure connections, durable finishes, clean welds, and a professional finish.

Mono-stringer stairs are a popular choice for modern interiors because the central steel support creates an open, architectural appearance while allowing the treads to remain visually prominent. They work particularly well in open-concept homes where the staircase is intended to become part of the interior design.
Each mono-stringer staircase needs must be built for its specific opening rather than treated as a standard product. Floor-to-floor height, stair width, tread dimensions, landing conditions, attachment points, and the surrounding structure all influence how the steel stringer is designed and fabricated.
The finished staircase can be paired with glass or custom metal railings to create anything from a highly minimal appearance to a more substantial architectural feature. For renovation and new construction projects in Ajax, Modern Stairs Plus can fabricate a custom mono-stringer system based on the project’s dimensions and design requirements.
Glass railings are an excellent choice for staircases, landings, balconies, and open interior spaces where maintaining clear sightliness is part of the design. They work particularly well with modern steel staircases because the glass keeps the overall structure visually open while allowing the staircase itself to remain the focal point.
Depending on the project, a glass railing system can be designed with stainless-steel posts, metal framing, standoffs, or a more minimal mounting system. The layout is planned around the staircase or guard area so panel dimensions, hardware locations, transitions, and connections are considered before installation begins.
For homes and commercial properties in Ajax, Modern Stairs Plus provides custom glass railing systems measured for the individual project. Careful alignment, secure mounting, consistent spacing, and clean finishing details are especially important with glass, where even small inconsistencies are easy to see.

Floating staircases are designed to create a lighter, more open appearance by minimizing the amount of visible structural support, In contemporary interiors, this can make the staircase feel less like a barrier between spaces and more like an architectural feature that connects them.
The clean appearance of a floating staircase depends heavily on what happens behind the finished surfaces. Attachment points, floor structure, wall conditions, stair geometry, and the method used to support the treads must all be considered early in the project. Depending on the design, the supporting steel structure may be exposed as part or the staircase or integrated more discreetly into the surrounding construction.
For renovations and new construction projects in Ajax, planning the staircase early also makes it easier to coordinate glass or metal railings, landings, finished flooring, and surrounding architectural details. The result is a custom staircase with the open appearance associated with floating stairs while still meeting the structural requirements of the individual project.
Double-stringer stairs use two steel supports to create a strong, balanced structure with a distinctive architectural appearance. Compared with the lighter visual profile of a mono-stringer staircase, this configuration can work particularly well for wider stairs, larger openings, and interiors where the steel structure is intended to be part of the design.
The position and proportions of the stringers are determined by the dimensions and layout of each project. Stair width, floor-to-floor height, landings, tread configuration, connection points, and the surrounding structure are all considered before fabrication begins.
For homes and custom projects in Ajax, double-stringer stairs can be coordinated with glass or metal railings to achieve either a clean contemporary look or a more substantial industrial-inspired design. Each staircase is fabricated to suit the individual space rather than adapted from a standard stair system.

Modern Stairs Plus provides custom steel stairs and metal railing systems for commercial properties in Ajax and the surrounding Durham Region. Our fabrication capabilities include interior and exterior steel stairs, landings, guardrails, handrailings, metal railings, and project-specific steel components.
Commercial projects require careful coordination of structural requirements, site considerations, safety consideration and installation. We work with builders, general contractors, designers, and other trades to help ensure each fabricated stair and railing system integrates properly with surrounding construction.

Modern Stairs Plus fabricates custom steel stair components for residential and commercial projects in Ajax. Our work includes stair stringers, landing frames, support brackets, mounting plates, handrail components and guardrail sections. These pieces connect the staircase to the surrounding construction and provide attachment points for treads and railings.
Custom fabrication is particularly useful when a renovation involves an unusual floor opening, restricted access or connections to an existing structure. The dimensions, steel profiles and fixing locations must suit the proposed installation. Tread materials and railing attachments are considered together so the components can be assembled as a coordinated system.
For exposed metalwork, the appearance of the finished piece also matters. Stringer profiles, visible joints and connections influence how the staircase looks alongside wood treads, glass panels and adjacent finishes. Reviewing these details before fabrication helps establish how the structural components will fit into the completed interior.
If your project requires modifications to an existing staircase, share photographs and available drawings with our team. We can review the proposed work and discuss whether individual fabricated components or a complete replacement would better suit the project.

Ontario weather can be demanding on exterior stairs. Snow, ice, rain, road salt, moisture, and repeated freeze-thaw cycles make material selection and finishing especially important for outdoor stair and railing systems.
Modern Stair Plus fabricates exterior steel stairs and metal railings for homes, commercial properties, secondary entrances, decks, porches, and other outdoor access areas in Ajax. Depending on the project, a system may include steel stringers, metal landings, guardrails, handrails, and custom components designed specifically for exterior use.
For exposed steel, protective finishing is an important part of long-term performance. Powder-coated or other suitable protective finishes can help reduce deterioration while providing a clean architectural appearance. Stair and railing layouts should also account for drainage, snow accumulation, safe access, and the way the structure connects to the building.
Exterior stairs do not have to look purely utilitarian. Clean steel profiles and carefully detailed railings can compliment both contemporary and traditional properties while providing a durable connection between entrance, patios, decks, and different outdoor levels.
For Ajax homeowners, builders, and commercial property owners, Modern Stairs Plus provides exterior stair and railing solutions tailored to the property, intended use, and architectural style.
