Choosing the Right Stair Nosings for Wet or Outdoor Areas

When it comes to outdoor or wet environments, selecting the right stair nosing is more than a design choice—it’s essential for safety. Proper stair nosings reduce slips, enhance visibility, and protect your stairs from wear. Whether upgrading public steps, commercial entrances, or home staircases, the right choice can make all the difference.

For detailed standards and regulations, see our Complete UK Stair Nosing Guide.

Why Are Stair Nosings Important in Wet or Outdoor Areas?

Outdoor stairs face rain, frost, algae, and other slip hazards. Stair nosings help by:

• Providing an anti-slip surface to reduce fall risk
• Enhancing step visibility through visual contrast
• Protecting stair edges from damage
• Ensuring compliance with building safety and DDA regulations

What Features Should You Look for in Outdoor/Wet Stair Nosings?

1. Weather-Resistant Materials

• Aluminium: Durable, corrosion-resistant, often anodised
• GRP(Fibreglass): Hardwearing, weatherproof, and slip-resistant
• Rubber inserts: Flexible, shock-absorbing, naturally slip-resistant
• Composite: Weatherproof plastics with grit inserts
• Stainless Steel: High durability, ideal for commercial use

Avoid untreated steel or basic PVC that degrades quickly outdoors.

2. Anti-Slip Performance

Choose nosings with anti-slip surfaces or inserts that meet PTV ≥ 36, the recommended UK standard for wet areas.

• GRP stair nosings for wet and outdoor steps
• GRP step tread covers for enhanced slip resistance
• Carborundum grit strips
• Ribbed PVC or rubber inserts
• Aluminium/stainless steel nosings with treadsafe inserts

3. Visual Contrast & Accessibility Compliance

• Minimum 30 LRV difference between tread and nosing
• Tactile surfaces for partially sighted users
• Consider GRP nosings with high-contrast grit surfaces for visually impaired users
