When it comes to electrical or utility housing, both GRP and metal cabinets have their place — but depending on the environment and application, GRP often comes out on top.
Weather Resistance #
- GRP: Completely corrosion-free, even in salt spray or coastal environments
- Metal: Prone to rust and paint peeling over time unless coated with care
Weight & Installation #
- GRP: Lightweight and easier to transport/install
- Metal: Heavier, requires more substantial mounting
Electrical Safety #
- GRP: Non-conductive, making it safer for electrical installations
- Metal: Requires earthing and extra precautions
Lifespan & Maintenance #
- GRP: No maintenance needed — no repainting or rust-proofing
- Metal: Requires occasional treatment to prevent corrosion
GRP is especially suitable for public spaces, roadside use, utility installations, and harsh outdoor conditions — making it the preferred choice for many sectors.
