How to Choose the Right FRP Outdoor Stair Tread – 300 × 800 mm Size Solution

Summary: Learn why FRP (Fiberglass Reinforced Plastic) stair treads in 300 × 800 mm size are ideal for outdoor stairways – covering durability, slip resistance, load capacity, surface treatment, installation, and ordering tips.

Why Choose FRP Stair Treads?

FRP (Fiberglass Reinforced Plastic) stair treads combine lightweight structure with high strength and superior corrosion resistance. Unlike steel, they do not rust; unlike wood, they are more durable and stable.

Corrosion Resistant: Resistant to rain, chemicals, and humid conditions.
Lightweight: Easy to handle and install, reducing labor and lifting costs.
Slip Resistant: Available with grit top or anti-slip pattern for enhanced safety.
Low Maintenance: No regular painting or anti-rust treatment required.

Why 300 × 800 mm?

The 300 mm depth and 800 mm width is a very practical and widely used specification:

300 mm depth ensures comfortable foot placement.
800 mm width is suitable for standard single-person access. For wider stairways, multiple treads can be installed side by side.

Custom sizes are also available to meet special project requirements.

Checklist Before Ordering

When requesting a quote, it's important to confirm the following:

Load requirements: Pedestrian, industrial, or equipment use?
Surface finish: Grit top, anti-slip pattern, or others.
Color options: Commonly grey or black, UV-resistant resin available.
Edge style: Square, rounded, or nosing.
Installation method: Bolt-on clamps, flange supports, or concrete embedment.
Operating environment: Near sea, chemical plants, or outdoor exposure – vinyl ester resin recommended for harsh environments.

Surface Treatment for Outdoor Use

For outdoor stairways, we recommend:

Grit top surface – long-lasting slip resistance and wear resistance.
Drainage openings – to reduce water accumulation and ice formation.
UV-resistant resin – prevents aging and discoloration from sunlight.
