Schneider Electric’s PanelSeT GRP range is engineered for the most demanding industrial, utility and infrastructure applications. Manufactured from glass-reinforced polyester (GRP), these enclosures combine mechanical strength, corrosion resistance and long-term reliability even in the harshest environments.

An ideal solution for harsh environments
PanelSeT GRP enclosures are particularly suited to applications exposed to:

• Corrosive atmospheres (chemical industries, water and wastewater treatment plants, coastal areas)
• High humidity or salt spray
• Extreme weather (sustained UV exposure, wide temperature fluctuations)

Unlike steel, GRP does not rust, requires no additional anti-corrosion treatment, and retains its mechanical properties over time, even in permanent outdoor installations.

GRP vs Steel: The case for certain sectors
In several market sectors, GRP is strongly recommended over steel due to its natural resistance to corrosion:

• Water and environment - Pumping stations, wastewater treatment plants, drinking water networks.
• Chemical and processing industries - Presence of corrosive vapours and aggressive chemical agents.
• Outdoor infrastructure - Tunnels, ports, coastal areas, rail

In these environments, steel enclosures, even when painted or treated, can deteriorate quickly, leading to corrosion, loss of sealing and increased maintenance costs. PanelSeT GRP extends service life, reduces downtime, optimising the total cost of ownership.

Safety and Compliance
PanelSeT GRP enclosures offer excellent electrical insulation, high resistance to impacts and shocks, and compliance with international standards (IEC, UL depending on references). They're built to protect critical electrical and electronic equipment, even under demanding operating conditions.

Flexibility and Ease of Integration
Designed with panel builders and system integrators in mind, the PanelSeT GRP range offers a wide choice of sizes and configurations, full compatibility with PanelSeT accessories, and easy machining for cable entries and equipment integration.

A Durable and Cost‑Effective Solution
Thanks to its corrosion resistance and long service life, PanelSeT GRP reduces maintenance requirements, limits premature replacements and supports a more sustainable approach to electrical installations.

Choosing PanelSeT GRP means selecting a reliable, high‑performance solution, specifically suited for segments where corrosion is a major challenge and where GRP clearly outperforms steel in terms of durability and safety.
