Stairs provide permanent access between floor levels and are a key structural and functional element in building construction. Used in residential and commercial projects, stair systems must meet specific requirements for load capacity, rise, going and overall geometry to ensure safe and compliant installation. Stairs are commonly installed during the structural and fit-out stages of construction, supporting access between storeys while integrating with surrounding joinery and finishes. Selected for strength, dimensional accuracy and compatibility with standard building layouts, stair systems support efficient installation and consistent performance on site. Suitable for new builds, extensions and refurbishment projects, trade stair products provide a reliable solution for internal access where durability, safety and regulatory compliance are essential.
