Mount Adams
A versatile architectural stair system built around exposed steel C-channel stringers, combining structural clarity, floating wood treads, and refined modern detailing.
System Overview
The Mount Adams stair system is built around a pair of precision-fabricated steel C-channel stringers that create a clean architectural framework while supporting substantial floating wood treads. The exposed channels provide both structural performance and visual definition, giving the stair a confident presence without excessive complexity.
Its straightforward geometry allows Mount Adams to integrate seamlessly into a wide range of architectural styles, from contemporary and transitional homes to modern mountain residences.
The combination of exposed steel channel construction, floating wood treads, and carefully detailed rail systems creates a stair that balances durability, craftsmanship, and long-term performance.
