DURABLE
Manufactured using American Grade 60 steel reinforcement and 4000 p.s.i. concrete 28 days, the Century closed riser stair treads have unparalleled structural strength and durability. The Century precast concrete stair treads will not rot like wood treads or rust
like metal treads especially in northern climates where salt and deicers are commonly used. Century's state-of-the-art mix design includes air entrainment and admixtures to insure the highest in quality and durability which allows the concrete stair treads to have a greater resistance to freeze-thaw and deicing agents. Do not use salts or deicers on stair treads. Use a penetrating sealer for protection once a year.
