4. Specification Notes
Installation: All products shall be installed in accordance with the manufacturer’s current written installation instructions. Stair nosing should be installed close to completion as some profiles have deep grooves that may be difficult to clean construction debris from. Where Korb supply-and-install service is specified, installation shall be performed by Korb-accredited installers.
Protection: Where nosing is installed prior to project completion, protect installed profiles from construction traffic and debris.
Substitution: No substitution of specified products shall be permitted without prior written approval from the architect/specifier. Proposed alternatives must demonstrate equivalent or superior compliance with the referenced standards.
Submittals: Contractor to submit product data sheets, test certificates (slip resistance, LRV where applicable), and installation method statement for approval prior to commencement of work.
Warranty: Manufacturer’s warranty as specified per product. Warranty covers defects in materials and workmanship under normal use conditions.
Standards: All products referenced against AS 1428 and AS 4586.
