Case Study
The KG Site Services project showcases how Engineered Composites’ GRP access platforms, complete with high grip GRP stair treads, delivered a fast, reliable and fully customised solution across several challenging industrial locations where traditional materials simply could not meet the brief.
Working within tight spaces and around awkward plant layouts, the team used lightweight structural GRP profiles to create safe elevated walkways, dosing bund surrounds and a rapid build access platform designed to slot neatly around existing machinery without hot works or heavy lifting.
The inclusion of durable quartz gritted GRP stair treads ensured every step offered secure footing in wet or chemical exposed areas, strengthening overall site safety while keeping installation efficient and disruption to a minimum. By combining chemical resistance, long term durability and quick on site assembly, the project demonstrated exactly why GRP platforms and stair treads are becoming the preferred choice for modern industrial environments.

FAQs About GRP Stair Treads
What are GRP stair treads and why are they used?
GRP stair treads are moulded or pultruded fibreglass reinforced panels designed to create safe, slip resistant steps in industrial, marine and public access environments. They offer a durable alternative to steel or timber, providing long lasting resistance to corrosion, moisture and chemical exposure while delivering excellent grip through a bonded quartz grit surface. Because they are lightweight and easy to install, GRP stair treads reduce on site labour, minimise downtime and give contractors a dependable solution for upgrading worn or unsafe staircases.
How do anti slip stair treads improve safety?
Anti slip stair treads are engineered with a high friction gritted surface that maintains traction even in wet, oily or high traffic conditions. This abrasive finish significantly reduces the likelihood of slips on stairs, especially in environments where metal or painted steps become hazardous over time. The bright, high visibility nosing on each tread also improves depth perception and helps users clearly identify each step, making anti slip stair treads a simple but highly effective way to raise safety standards across any access route.
Are GRP stair treads suitable for outdoor and harsh environments?
Can GRP stair treads be installed over existing steps?
Do GRP stair treads meet fire and safety standards?
Engineered Composites supplies GRP stair treads manufactured to meet recognised safety standards including BS 476 Class 2 or ASTM E84 Class 2 for fire performance. They are non conductive, corrosion proof and designed to support safe movement in industrial, marine and public environments where compliance is essential. The anti slip surface is tested for reliable traction, ensuring that GRP stair treads deliver consistent safety benefits across a wide range of applications.
Can GRP stair treads be used with GRP stair nosings and GRP flooring?
GRP stair treads work seamlessly alongside GRP stair nosings and wider GRP flooring systems, allowing contractors to create complete access solutions that are consistent in performance, slip resistance and visibility. GRP stair nosings enhance the leading edge of each step, while matching GRP flooring panels provide a safe transition between stairs and adjoining walkways. Using these components together delivers a fully integrated, long lasting and low maintenance system suitable for demanding industrial and public environments.
