What materials are Sterplas composite electrical distribution panels made of?

Sterplas composite electrical distribution panels are manufactured from Glass Reinforced Polyester (GRP/FRP), also known as Glass Fiber Reinforced Plastic. This material provides excellent mechanical strength, lightweight construction, superior corrosion resistance and long service life for demanding industrial environments.

Can the panels be used outdoors?

Yes. Sterplas composite electrical panels are designed for outdoor use and offer excellent resistance against UV rays, rain, snow, humidity, salt air and harsh environmental conditions.

Do composite electrical panels rust?

No. Composite materials do not rust, corrode or rot because they contain no metal. This significantly reduces maintenance costs throughout their service life.

Are the panels resistant to chemicals?

Yes. Their GRP composite structure provides excellent resistance against many acids, alkalis and chemicals, making them ideal for chemical plants, water treatment facilities and industrial processes.

Can you manufacture custom-sized electrical panels?

Yes. In addition to standard products, Sterplas designs and manufactures custom-sized composite electrical distribution panels according to project requirements.

Are different color options available?

Yes. Panels can be manufactured in a wide range of RAL colors according to customer requirements.

Do composite panels provide electrical insulation?

Yes. Composite materials naturally provide electrical insulation, improving operational safety and protecting electrical equipment.

Do you offer mass production?

Yes. Sterplas provides OEM and Private Label manufacturing, from prototype production to high-volume mass production.

Do you export your products?

Yes. Sterplas exports composite products to Europe and many other international markets while supporting global industrial projects.

Do you provide technical support?

Yes. Our experienced engineering team provides technical support throughout the entire project, including design, product selection, drawing evaluation and manufacturing.

Do composite electrical panels require maintenance?

Composite electrical panels require very little maintenance. They do not rust, rot or require repainting, ensuring reliable long-term performance.

Are the panels delivered ready for installation?

Yes. Depending on project requirements, panels can be supplied ready for installation with mounting plates, locking systems, hinges, ventilation units, cable entries and other accessories.
