Frequently Asked Questions (FAQs)

  • What are single stringer stairs?

    Single stringer stairs have a single central beam that supports the steps. This design gives the stairs a clean, open appearance while keeping them strong and stable. It’s a popular choice for modern spaces because of its sleek and minimalist look.

  • Why should I choose single stringer stairs?

    Single stringer stairs are a great option if you’re looking for something that’s both stylish and functional. They create a floating effect, making your space feel more open. Plus, you can customize the treads and handrails to match your interior, giving you plenty of design flexibility.

  • Can single stringer stairs be made in different layouts?

    Yes, single stringer stairs can be designed in different configurations. You can go with a straight-line design, an L-shape, or a U-shape (also called a switchback). You can even combine them with other styles, like curved or spiral stairs, for a unique look.

  • What materials are available for single stringer stairs?

    We offer a variety of materials to build your single stringer stairs. Options include rectangular or square steel tubes, round steel tubes, and even a tri-frame design made from three pipes. These materials are strong and give your stairs a modern, durable finish.

  • How much can I customize my single stringer stairs?

    You can fully customize your single stringer stairs. From the type of stringer to the treads and handrails, you have control over the design. It ensures the staircase fits your space and style, whether you’re installing it in a home or a commercial building.

  • Are single stringer stairs safe and durable?

    Yes, single stringer stairs are built to be safe and durable. The central stringer provides strong support for the steps, and we use high-quality materials so that the stairs last for years. They’re designed for everyday use and built to handle the wear and tear of daily life.

  • Do single stringer stairs require more maintenance than traditional stairs?

    Not necessarily. Maintenance depends on the materials used. Wood treads may require occasional refinishing, while metal and glass treads need periodic cleaning. The steel stringer is highly durable and resistant to wear, needing only occasional dusting or wiping. If you opt for open risers, dust accumulation underneath is reduced compared to traditional stairs. Routine inspections ensure long-term performance, but overall, these stairs are low-maintenance.

  • Can single stringer stairs be installed in both residential and commercial spaces?

    Yes! Single stringer stairs work beautifully in both settings. Residential installations create an open, elegant feel, making spaces look larger and more modern. In commercial spaces, such as offices, showrooms, or retail stores, they add a sophisticated, high-end appeal. We design each staircase to meet local building codes, ensuring safety and compliance for any setting.

  • What is the installation process like?

    Installation begins with precise measurements and design planning. Once fabricated, the staircase is shipped and installed by professionals. The process involves anchoring the steel stringer securely, attaching the treads, and installing railings. Depending on the complexity, installation typically takes a few days. For nationwide deliveries, we provide detailed installation guides and support for contractors. Proper planning ensures a smooth, efficient setup.

  • Do single stringer stairs cost more than traditional stairs?

    While the initial cost may be higher due to custom fabrication and premium materials, single stringer stairs offer long-term value. Their durability, modern appeal, and space-saving design add resale value to your property. The open aesthetic can reduce the need for additional lighting, and their timeless style minimizes the need for future renovations. Investing in high-quality stairs can enhance both function and design.

  • Can I install single stringer stairs in a small space?

    Yes! One of the biggest advantages of single stringer stairs is their space efficiency. They take up less visual and physical space than traditional staircases, making them ideal for smaller homes, lofts, or apartments. Their open design allows more light to flow through, preventing spaces from feeling cramped. If space is limited, we can customize the staircase to maximize functionality while maintaining aesthetics.

  • Are there any building codes or regulations I need to be aware of?

    Yes, and we ensure all designs comply with local codes. Building codes typically dictate tread depth, riser height, railing height, and load-bearing capacity. If installing in a commercial space, additional regulations may apply. We work closely with clients to ensure compliance while maintaining design integrity. Before ordering, it’s important to check with local authorities or a contractor to ensure smooth approval.

  • Can single stringer stairs be used outdoors?

    Yes! Single stringer stairs can be designed for outdoor use with weather-resistant materials. We offer galvanized or powder-coated steel for the stringer, and treads can be made from weather-resistant hardwoods, composite materials, or perforated metal. Proper drainage and coatings help prevent rust and deterioration. Outdoor applications are great for decks, balconies, and garden access, providing a stylish yet durable solution.

  • What are some misconceptions about single stringer stairs?

    A common misconception is that they are weak or unstable due to their minimalist design. In reality, they are engineered for strength and can hold significant weight. Another myth is that they are difficult to install—while they require professional installation, they are no more complex than other custom staircases. Some also believe they don’t fit traditional homes, but with the right materials and finishes, they can complement classic, industrial, or rustic styles.

  • What should I consider when choosing the right treads?

    Tread material affects aesthetics, maintenance, and safety. Wood provides warmth and traditional appeal, while glass enhances a modern, airy look. Metal treads are great for industrial designs, and stone or concrete adds a bold, luxurious touch. Consider durability, slip resistance, and maintenance. If you prefer a softer surface, wood with anti-slip coatings is a great option. We help clients choose the best materials for their space and lifestyle.
