Utility poles Fibreglass -Composite

For over thirty years, Top Glass has produced TAPERED FIBREGLASS UTILITY POLES using CENTRIFUGAL CASTING, a technology developed entirely inside the company and drawing on its design capabilities and production systems.
Due to their mechanical properties and strong resistance to atmospheric agents, fibreglass poles ( GRP ) adapt to various uses including as traffic light poles, lighting poles, advertising poles, signage and street furniture, flagpoles, electrical and telephone line supports.

Fibreglass makes these poles both lightweight and easily portable by hand. Top Glass poles do not require concrete plinths for installation or grounding in the presence of electrical equipment.

They do not require additional surface treatment (such as painting) or periodic maintenance. These features make Top Glass poles inexpensive compared to traditional options in steel, aluminium, wood or concrete.
All of our poles are certified according to EC directives.
