Metal Staircases
Metal Staircases: Choosing the Right Design for Your Project
In the realm of architectural design and construction, metal staircases are a staple for both functional and aesthetically pleasing elements. In this guide, we will explore three primary types of metal staircases - traditional channel stringer staircases, mono stringer or "floating" staircases, and spiral staircases - detailing their characteristics, typical applications, and their use cases. We will do our best to give an honest and unbiased evaluation of each type, and offering insights for homeowners and project estimators on pricing, logistics, and planning.
1. Traditional Channel Stringer Staircases
Traditional channel stringer staircases are a classic and widely used design, featuring a central beam with channels supporting the treads. These staircases are known for their utility and straightforward construction. Most exterior staircases fit this description! In this layout the stair treads rest between the stringers.
Typical Applications
Commonly used in both residential and commercial settings, traditional channel stringer staircases are versatile and can complement various architectural styles. They are suitable for both interior and exterior applications. Common in both interior and exterior settings, this type of staircase is one of the most used in construction worldwide.
Pros
Sturdy Construction: Simple is effective. This layout is stable, straight forward to design, and relatively simple to build. These staircases can withstand heavy traffic and most welding shops will have the experience necessary to provide them.
Versatility: This layout is widely used in both interior commercial spaces, nearly all industrial spaces, and commonly in exterior residential applications such as fire escapes and platform access.
Cons
Industrial Appearance: This layout tends to look more industrial due to where we see it most. Sometimes this is covered by other trades later in the construction project, other times the stringers remain exposed and the staircase will influence the resulting style and presence of the space.
2. Mono Stringer or "Floating" Staircases
Mono stringer staircases, often referred to as "floating" staircases, feature a single, centrally located stringer supporting the treads. This design imparts a sense of modern elegance and visual lightness. Most often the stringer is composed of a large profile steel tube, though alternative designs occasionally use I-beams. Additional variations exist with two stringers that run beneath the stair treads where additional structure may be desired. In this layout, the treads sit on top of the stringers.
Typical Applications
Ideal for contemporary and minimalist designs, mono stringer staircases are popular in residential spaces, especially where an open and airy feel is desired. This layout is growing in popularity in commercial applications as well for their impressive visuals and contemporary design. University libraries, construction company showrooms, and architectural offices may employ this style.
Pros
Aesthetic Appeal: Offers a sleek and modern appearance, enhancing the overall design of the space.
Space Efficiency: Takes up less visual space due to the absence of additional side stringers.
Cons
Cost: Generally more expensive than traditional designs due to the complexity of design, engineering, fabrication, and installation.
Technical Expertise: Requires skilled craftsmanship for precise installation. Many shops will not be knowledgeable or experienced enough to design and build a staircase of this style. Choosing a contractor you trust with the project is essential.
3. Spiral Staircases
Spiral staircases are characterized by a helical structure, with treads radiating around a central pole. This design is both visually striking and space-efficient. Their dramatic visual appeal is stately, and a unique blend between classic architecture and more contemporary designs.
Typical Applications
Perfect for compact spaces, spiral staircases find their niche in both interior and exterior applications, such as accessing lofts, rooftop terraces, or as a focal point in architectural designs. Often they are used in places where no other layout is possible, due to space constraints. They are impressive, and can be used to make a design statement.
Pros
Space Efficiency: Occupies minimal floor space, making it an excellent choice for tight quarters.
Architectural Focal Point: Adds a unique and captivating element to the overall design.
Cons
Cost: These staircases are generally as costly as they are impressive. The complexity of design, engineering, fabrication, and installation requires a skilled team and plenty of collaboration.
Technical Expertise: Requires skilled craftsmanship for challenging fabrication and installation procedures. Most shops will not be knowledgeable or experienced enough to design and build a staircase of this style. You must choose a contractor you trust. Many shops may not be able to perform this work.
Limited Width: May not be suitable for areas requiring the movement of large furniture or items.
Accessibility: Might be challenging for individuals with mobility concerns.
Conclusion
Choosing the right metal staircase for your project involves a thoughtful evaluation of design preferences, space constraints, and budget considerations. Whether opting for the classic appeal of traditional channel stringer staircases, the modern elegance of mono stringer designs, or the space-efficient charm of spiral staircases, choosing a contractor you trust ensures a seamless integration of functionality and aesthetics into your space and a successful project outcome.
