What are the standard sizes/thicknesses of aluminum stair nosing?
Aluminum stair nosing is a key element of stair safety and design, offering features such as anti-slip, edge protection, and a polished surface. If you're wondering about standard sizes and thicknesses, here's a guide to choosing the right size and thickness for your stair treads.
Standard Sizes and Thicknesses
While sizes may vary slightly from manufacturer to manufacturer, most aluminum anti slip stair treads follow these general specifications:
Width:
Standard: 30 mm to 150 mm (1.2 in to 6 in)
Common choices: 50 mm (2 in), 75 mm (3 in), or 100 mm (4 in) to match the depth of your stair treads.
Thickness:
Base Material: 1.5 mm to 3 mm (0.06 in to 0.12 in)
Thicker options, such as 2 mm to 3 mm, are ideal for high-traffic areas such as airports or commercial buildings.
Length:
Standard: 2m to 6m (6.5ft to 20ft)
Custom lengths are often available to minimize seams and ensure a seamless installation.
Anti-slip strips:
Anti-slip pads (silicon carbide, rubber or grooved) typically span 10mm to 20mm.
Why are size and thickness so important?

Safety:
Widened nosing and solid thickness increase slip resistance and durability.
Aesthetics:
Proportional size ensures a clean and professional look.
Compliance:
Meets building codes for public spaces (e.g. ADA, OSHA).
