Builders Series Spiral Staircase

Paragon’s Builder’s Series are designed for increased durability without sacrificing the sleek style of a spiral stair. Ideal for areas with heavy foot traffic, the steps, spindles, and handrail all come together to form a support system throughout the staircase. The connections are made to handle a heavier weight than other designs. Different tread profiles and finishes allow you to make this long lasting staircase your own.
