Ecoglo® S4051 Yellow Luminescent Cast In Place Stair Nosing | S4-E30
Ecoglo® S4051 is the yellow anti-slip model in the S4-E30 photoluminescent cast-in-place stair-nosing series. Designed for new concrete stair construction, the profile installs directly into wet concrete to create a durable, flush stair edge combining photoluminescent visibility with hard-wearing silicon-carbide slip resistance.
Photoluminescent Cast-In-Place Stair Nosing for Concrete Stairs
Ecoglo® S4051 is engineered for concrete stair projects where architects, general contractors, concrete contractors, estimators and facility owners require a permanent stair-edge solution combining visual contrast, slip resistance and photoluminescent visibility.
Unlike surface-applied tapes or retrofit stair-nosings, the S4-E30 profile is installed directly into wet concrete during construction. This allows the stair nosing to become integrated with the concrete stair and helps create a smooth, flush transition at the leading edge.
In normal lighting, the contrast between the yellow anti-slip surface and the photoluminescent strips helps define the edge of each step. When normal lighting is reduced or lost, the photoluminescent strips continue to provide visible step-edge definition without requiring electrical power at the stair nosing.
Cast Directly Into Concrete
Designed for installation into wet concrete on new concrete stairs, concrete-filled steel-pan stairs and precast concrete stair systems.
Yellow Silicon-Carbide Anti-Slip
Hard-wearing yellow silicon-carbide non-slip material is integrally bonded to the aluminum substrate to provide durable traction and enhanced high-visibility stair-edge contrast.
Passive Emergency Visibility
Ecoglo® photoluminescent technology helps maintain visible step-edge definition when normal lighting conditions are reduced.

Engineered for High-Traffic Concrete Stairways
Ecoglo® designed the S4-E30 cast-in-place profile for demanding commercial and institutional environments where long-term stair-edge visibility, traction and durability are important.
- Raised ridges help protect the photoluminescent strips from abrasive wear.
- The ridged photoluminescent surface also contributes additional slip resistance.
- Hard-wearing silicon-carbide non-slip material is integrally bonded to the aluminum substrate.
- Cast-in-place installation creates a smooth transition between the nosing and surrounding concrete.
- 6063-T5 mill-finish aluminum is protected with a clear acrylic lacquer finish.
- The profile is designed for concrete stairs, concrete-filled steel-pan stairs and precast stairs.
- Ecoglo® reports accelerated UV and weathering testing for indoor and outdoor applications.
- Manufacturer testing reports performance loss below visually detectable levels following 6,000 hours of accelerated UV exposure.
- Aluminum-based construction is recyclable.
- Photoluminescent operation requires zero electrical energy at the stair nosing.
Cast-In-Place Installation for New Concrete Stairs
S4051 is intended to be incorporated into the concrete stair during construction rather than installed as a surface-mounted retrofit after the concrete has cured.
1. Coordinate Before the Pour
Confirm the architectural stair detail, finished nosing location and required lengths before concrete placement begins.
2. Install Into Wet Concrete
Position the S4-E30 profile in accordance with approved project documents and current manufacturer installation guidance.
3. Protect During Construction
Ecoglo® supplies protective tape around the product to help keep the nosing clean during installation and construction.
How Ecoglo® S4051 Can Help Reduce Avoidable Project Delays
On large commercial, government and institutional projects, concrete stair-edge details should be resolved before the concrete is poured. Incorrect product selection, missing documentation or uncoordinated stair details can create RFIs, rework and avoidable project delays.
Identifying the exact manufacturer → series → model → technical data → approved detail → installation provides a clear documentation path from specification through final construction.
1 Specify the Exact Model
Identify the product as Ecoglo® S4051 Yellow, S4-E30 Series rather than using only a generic description such as “photoluminescent concrete stair nosing.”
2 Confirm the Concrete Stair Detail
Review the architectural stair detail and confirm that the S4-E30 cast-in-place profile has been coordinated with concrete stair geometry before installation.
3 Include the Manufacturer Data Sheet
Include the S4-E30 technical data sheet with project submittals so dimensions, materials, installation method and listed product information can be reviewed.
4 Coordinate Before Concrete Placement
Because S4051 installs into wet concrete, the nosing location and elevation should be coordinated with the concrete contractor before and during the pour.
5 Protect the Product During Construction
Retain the manufacturer's protective covering as appropriate during construction to help prevent contamination and damage.
6 Keep Documentation for Final Review
Retain approved product submittals, model numbers, technical documentation and installation records for consultant and inspection review.
