Pricing Ecoglo® for a Bid, Tender or Large Construction Project?
ComposiGrip supports commercial and public-sector project teams that need Ecoglo® quantities, product documentation, cut-length planning and project pricing. Use the Ecoglo Estimator & Bid Center to organize the information needed for a faster project review.
For more accurate estimating, confirm the following before submitting an RFQ or including S4070 in a bid schedule.
Review product dimensions, standard lengths, aluminum finish, insert options, installation information and published performance testing.
Open S4-N30 Data Sheet →The published S4-N30 profile is approximately 2.2" (56.8 mm) wide. The manufacturer's dimension detail also shows a nominal 0.8" (19.7 mm) overall profile depth, an approximately 0.6" (15.9 mm) embedded stem depth, and an approximately 0.6" (14.7 mm) anchor-foot width.
S4-N30 is installed directly into wet concrete. The product can be used on concrete stairs, concrete-filled steel pan stairs and precast concrete stairs. Coordinate final placement with the approved project detail and the manufacturer's current installation requirements.
Ecoglo® identifies S4-N30 inserts as available attached or unattached. Supplying the insert unattached allows the insert to be installed later, helping keep the finished anti-slip surface clean and protected while other construction work is underway. The insert is installed with premium polyurethane adhesive.
The current manufacturer data sheet lists the following test methods and standards. Project teams should compare the current documentation with the actual specification, contract documents and Authority Having Jurisdiction requirements before final approval or bid submission.
The current Ecoglo® S4-N30 data sheet identifies the aluminum-based product as 100% recyclable and states that approximately 20% of the aluminum content in an Ecoglo secondary billet specification is recycled scrap. It also identifies LEED-related credit considerations. The project LEED professional should determine whether and how the product contributes to the specific project's certification strategy.
Send ComposiGrip the project name, location, estimated quantity, required lengths, bid date, specification section and required delivery date. We can help organize S4-N30 product information for estimating and project review.

Frequently Asked Questions About Ecoglo® S4070 Black S4-N30
Product and estimating answers for contractors, preconstruction teams, estimators, quantity surveyors, architects, specifiers, procurement teams and project managers evaluating the Ecoglo® S4070 Black S4-N30 cast-in-place stair nosing.
What is Ecoglo® S4070 Yellow?
Ecoglo® S4070 is the Black version of the S4-N30 non-slip cast-in-place stair nosing. It is a 2.2-inch-wide aluminum stair-edge profile with a hard-wearing silicon-carbide anti-slip surface. The product is installed directly into wet concrete.
Is S4070 Black photoluminescent or glow-in-the-dark?
No. S4-N30 is the non-slip, non-photoluminescent cast-in-place series. The Black S4070 surface is a non-photoluminescent anti-slip insert with a dark architectural appearance; it does not function as a photoluminescent glow strip.
Why would a project specify the Black S4070 instead of Yellow or Gray?
Black provides a dark architectural stair-edge finish that can create clear visual definition against lighter concrete, tile or surrounding finishes. Yellow S4050 provides the most visually prominent color option, while Gray S4060 offers a more neutral alternative within the same S4-N30 series.
What stair construction is S4-N30 designed for?
S4-N30 is installed into wet concrete and is identified for concrete stairs, concrete-filled steel pan stairs and precast concrete stairs. The final stair detail should be checked against the project drawings, specification and current manufacturer installation information.
What are the published S4-N30 dimensions?
The manufacturer's dimension drawing shows an overall top width of approximately 2.2" (56.8 mm). It also shows approximately 0.8" (19.7 mm) overall depth, approximately 0.6" (15.9 mm) embedded stem depth, and approximately 0.6" (14.7 mm) anchor-foot width.
What lengths are available for S4070 Black?
Standard S4-N30 lengths are 8 FT and 10 FT. Cut-to-length sizes are also available, with the manufacturer listing an approximate tolerance of ± 1/8 inch.
Can S4-N30 inserts be supplied unattached for a construction project?
Yes. The manufacturer lists inserts as available attached or unattached. Unattached inserts can be installed later in the construction sequence to help keep the finished anti-slip surface clean and reduce the chance of construction damage. The insert is installed with premium polyurethane adhesive.
Can S4070 Black be used indoors and outdoors?
The S4-N30 data sheet identifies the product for indoor and outdoor use and lists testing for accelerated UV/weathering exposure, salt spray resistance, freeze-thaw resistance and washability. Final suitability should still be confirmed for the actual project exposure and specification.
What slip-resistance testing is listed for S4-N30?
The current S4-N30 manufacturer data sheet lists UL 410 and AS/NZS 4586-1999 under slip-resistant performance. Estimators and specifiers should use the current data sheet when comparing the product with a bid specification.
What information should an estimator send for S4-N30 project pricing?
For a faster project review, provide the project name, project location, stair count, finished stair widths, required lengths, selected S4-N30 color/model, estimated quantity, bid due date, required delivery date and relevant specification section.
If available, also send stair details, product schedules and submittal requirements.
Can S4070 Black be quoted for government or institutional projects?
ComposiGrip can review S4070 and other Ecoglo® products for commercial, institutional and public-sector bid packages. Product acceptance depends on the actual contract documents, project specification, drawings and applicable code or Authority Having Jurisdiction requirements.
For government tenders, include the relevant specification language and required submittal documents with the pricing request.
Does the S4-N30 data sheet include sustainability information?
Yes. The current manufacturer data sheet states that the aluminum-based product is 100% recyclable and that approximately 20% of the aluminum content in an Ecoglo secondary billet specification is recycled scrap. It also identifies LEED-related credit considerations. The project's LEED professional should determine the final credit contribution.
Where can I get S4-N30 technical documents, CAD details and bid support?
Use the S4-N30 technical data sheet for published dimensions, installation information and performance testing. CAD resources can support detail coordination, while the ComposiGrip Ecoglo Estimator & Bid Center is intended for project pricing and larger bid opportunities.

General Information
Install with premium polyurethane adhesive.
- Option for mechanical fasteners.
- Do not use mechanical fasteners when installing outdoors.
- Available in cut to length sizes. (Tolerance +or- 1/8”) Standard lengths are 8ft and 10ft.
- Weight: 0.1 lbs/ft.
Engineered for Durability
- Manufactured using Ecoglo®’s patented process which produces the most durable and highly efficient photoluminescent product available.
- Unique ridges in the photoluminescent strips protect it from most abrasive wear. They provide slip resistance while still allowing the product to be easily cleaned.
- The hard-wearing silicon carbide non-slip material is integrally bonded to the aluminum substrate. Thousands of people can walk on it with no signs of wear and tear.
Superior Step Edge Safety
- The color contrasting the non-slip material with advanced photoluminescent technology provides step edge visibility in all light conditions.
- The unique ridges in the Ecoglo® photoluminescent strips and the integrated anti-slip contrast strips provide all-weather slip resistance.
Installed Durability:
- The rigid aluminum base spreads any applied load over a greater area of installation adhesive. Installation with a premium polyurethane adhesive/sealant is extremely durable, moisture resistant, and works very well on both smooth and textured surfaces.
For Indoor Use and Outdoor Use:
- Tested to accelerated UV/weathering exposure, and proven to be highly resistant to the effects of UV/weathering.
- The loss in performance is less than can be detected by the human eye when subjected to 6000 hours of UV exposure, which is similar to 30 years of outdoor exposure.
- The polymer used in Ecoglo’s patented process is “long chain” which forms a strong UV resistant product when bonding.
Environmentally Friendly Photoluminescent Contrast Strip
- LEED points qualified
- Zero energy consumption
- Non-Radioactive and Non-toxic
- Recyclable; No disposable cost
