FRP Tank, Pit & Hoist covers
Custom-moulded composite covers engineered for protection and longevity
We design, manufacture and install bespoke FRP (Fibre Reinforced Polymer) covers that provide durable, corrosion-free protection for your critical infrastructure. Whether you’re safeguarding a chemical tank, a maintenance pit or hoisting equipment, our custom-moulded covers are built to your exact requirements — delivering strength, reliability and long-term peace of mind.
Is your existing tank cover failing?
Steel tank lids and covers are prone to corrosion — especially in environments exposed to chemical vapours, condensation, and weather extremes. Over time, this leads to:
- Contamination of stored contents
- Structural weakening and safety risks
- Costly repairs or full replacement
Switching to a custom FRP cover eliminates these problems. Our covers are non-corrosive, impact resistant, watertight, and engineered for the specific demands of your environment.
Why Choose FRP for Tank, Pit and Hoist Covers?
Fibre Reinforced Polymer (FRP) offers outstanding material performance where traditional metals fail. With a high strength-to-weight ratio and the ability to resist aggressive chemicals, FRP is ideal for protective covers in industrial, commercial and marine environments.
Key benefits:
- Corrosion-proof – no rust, no rot
- Chemical resistant – built to withstand aggressive environments
- Watertight and seamless – ideal for containment
- Lightweight but strong – easier to install and handle
- UV and weather-resistant – built for outdoor use
- Customisable – moulded to your exact size, shape and specification

Your FRP Roof & Cover Guide
Steel may be the traditional choice — but it comes with known problems: rust, chemical degradation, and eventual failure. Our FRP covers offer a modern, maintenance-free alternative:
- No welding or repainting
- Longer service life
- Easier to install and move
- Customisable for access, insulation and fit
- Fully compliant with environmental and safety standards
We tailor every project to your needs — from the right shape and strength to chemical compatibility and access considerations.
