STNP: 2” ABRASIVE
POUR-IN-PLACE STAIR
The low-profile STNP 2.0” wide abrasive stair nosing is designed with a replaceable 1“ photoluminescent marking or sand-grit insert strip to meet slip-resistance and contrasting stripe requirements. The PVC isolator protects against galvanic corrosion between the aluminum nose and concrete. The aluminum nose is replaceable. The nosing includes a patented protective cover to prevent damage during installation and through construction. Suitable for both interior and exterior environments.
Designed for installation just before the concrete pour. The stair nosing clips on to the 14-10ga x 3/4” metal pan nose holding its position during the concrete pour. Creates a bull nose radius of 5/16”.
Constructed from durable aluminum adhered to the PVC isolator using high bond 3M VHB adhesive. Its slim profile and square back edge creates a flush transition from nose to tread. Multiple colors, finishes and options are available to match project aesthetics or meet specific code requirements.
Code Compliance:
- Complies with IBC, IFC, NFPA, ASTM, OSHA, ADA and California Title 24 contrasting stripe requirements.
- UL Approved.

FREQUENTLY ASKED QUESTIONS
What is a STNP pour-in-place aluminum stair nosing with PVC Isolator?
The STNP pour-in-place aluminum stair nosing with PVC isolator is designed to prevent galvanic corrosion between the aluminum nose, stair pan, and concrete fill. The PVC isolator clips securely to a 14–10ga × 3/4” pan nose prior to the concrete
pour and remains in place during placement. The aluminum nose is replaceable, with stripe options available to meet specific project requirements. This nosing enhances slip resistance, visibility, and long-term durability for commercial stairways. For alternative models suited to pan-filled stair construction, refer to the STNC3 and STNC3-RB.
What is the purpose of the STNP stair nosing removable protective construction cover?
STNP stair nosings feature a removable protective construction cover that shields the nosing surface during concrete placement and construction traffic. This cover protects the visible strip and aluminum finish, ensuring a clean, professional appearance at project completion. After construction, the cover peels away easily, revealing a like-new surface ready for occupancy.
Are STNP stair nosings compliant with IBC, ADA, and Title 24 codes?
Yes, STNP stair nosings are manufactured to meet or exceed International Building Code (IBC), Americans with Disabilities Act (ADA), and Title 24 contrasting stripe requirements for stair safety. Available color options, contrasting visual strips with slip-resistant surfaces, help projects meet and exceed code compliance.
Can STNP stair nosings be used on cast-in-place or precast concrete stair treads?
No, STNP stair nosings are specifically designed to fit metal pan filled stairs. See our stair nosing models STNC, STNC-RB, STNC3, and STNC3-RB for cast-in-place or precast concrete treads.
What finish options are available for the STNP stair nosings?
We offer a range of PVC isolator colors, aluminum finishes, and insert strip options to suit project needs. Choices include photoluminescent glow-in-the-dark strips, abrasive grit strips, mill finish, anodized aluminum, and durable powder-coated finishes. These options enhance visibility, support code compliance, and provide customizable safety solutions.
