Square edge stair nosings deliver a clean, modern look while providing excellent protection. Here's why professionals specify square profiles.
What is a Square Profile?
Unlike bullnose (rounded) or pencil (small radius) profiles, square nosings have a sharp 90° edge wrapped with a protective covering. The profile typically extends:
- 25-40mm over the tread surface
- 15-25mm down the riser face
Why Choose Square?
Clean Aesthetics
The crisp lines suit contemporary interiors, commercial fit-outs, and architectural projects where design matters.
Maximum Protection
The wrapped edge fully covers the stair corner—the area most vulnerable to damage.
Compliance Ready
The 25mm tread coverage meets Part K visibility requirements when combined with contrasting inserts.
Ease of Cleaning
Simple geometry makes square nosings easy to clean and maintain.
Material Options
- Aluminium – Most popular choice. Available in mill finish, anodised, or powder-coated.
- Brass Effect – Aluminium with brass anodising for a warm, traditional look.
- Stainless Steel – Premium option for high-spec commercial and residential projects.
Applications
- Office buildings
- Retail spaces
- Hotels and hospitality
- Modern residential
- Educational facilities
- Healthcare buildings
Installation
Square profiles can be:
- Surface-mounted with visible fixings
- Rebated flush with the tread
- Fixed with concealed clips
Rebated installation creates the cleanest look but requires more preparation.
