GRP Enclosures – Durable and Weather-Resistant Electrical Housings

Unlike traditional metal enclosures, GRP enclosures are non-conductive, UV-resistant, and highly durable, making them perfect for harsh environments where exposure to moisture, dust, chemicals, or extreme temperatures is a concern. Their IP-rated protection, combined with high impact resistance (IK10), ensures that electrical systems remain safe from environmental damage.

Key Benefits of GRP Enclosures
  • Corrosion-Resistant – Ideal for coastal, industrial, and chemical-heavy environments
  • Lightweight Yet Strong – Easier to install and transport compared to metal alternatives
  • Electrical Insulation – Non-conductive material enhances electrical safety
  • Weatherproof Protection – IP66/IP67-rated, shielding against dust, moisture, and water jets
  • Flame Resistant – Meets stringent fire safety standards with high-temperature resistance
  • Customisable & Easily Machinable – Can be modified to suit various applications
Common Applications
  • Industrial Control Panels – Protects electrical control systems in manufacturing and processing plants
  • Outdoor Power Distribution – Provides weatherproof housing for electrical connections
  • Renewable Energy Installations – Used in solar, wind, and EV charging applications
  • Marine & Coastal Areas – Resists saltwater corrosion, making it ideal for dockside and offshore installations
  • Hazardous Environments – Suitable for chemical plants, refineries, and food processing facilities
Why Choose GRP Enclosures?

GRP enclosures provide a versatile and cost-effective alternative to metal enclosures, delivering unmatched resistance to corrosion, impact, and extreme weather conditions. Their lightweight yet robust construction ensures long-lasting durability, making them an ideal choice for high-demand electrical installations.
