FAQ
Here are some common questions about our company.
We use laminated tempered glass with varying thicknesses depending on the mounting type.
Yes. The California Building Code requires a continuous, graspable handrail along all stairways between 34 and 38 inches vertically from the stair nosing.
We offer a few sleek solutions that match our minimalist design: an ultra - slim metal or wood top-cap rail that sits directly on top of the glass pane, or a side-mounted handrail fixed directly through the glass via stainless steel standoffs.
What exactly is a Central Spine staircase?
Often called a mono-stringer, a central spine staircase uses a single, heavy - duty structural steel beam running directly down the center beneath the steps.
We offer two distinct, clean mounting methods for our glass panels:
Standoff Pin System: Heavy-duty, round stainless steel pins are mounted directly into the sides of the treads or the metal support plates, suspending the glass along the edge of the stairs.
Base Shoe / Channel System: The glass slides into a hidden structural metal channel running along the side of the stringer or the floor, creating a completely seamless look with no visible hardware.
Absolutely. Our central steel spines are finished in high-grade architectural powder coatings, and all of our glass mounting hardware is made from Marine-Grade 316 Stainless Steel to completely eliminate rust and salt-air staining in coastal markets like Malibu, Newport Beach, or the Bay Area.
Because a central spine staircase concentrates all its weight into just two main pivot areas—the very top and the very bottom—your subfloor and header require structural backing.
Top Header: Needs solid multi-ply blocking or steel beams to handle heavy pulling forces.
Bottom Footing: Usually requires mounting directly into a concrete slab or engineered floor joists.
