Half round profiles – fiberglass

Top Glass manufactures HALF ROUND SECTION profiles (GRP – FRP- CRP)made in composite material.Our products are reinforced with fibreglass and they represent one of the pultruded profiles made by Top Glass.
Partially available from stock, our pultruded profiles are indispensable in the production of electrical devices such as dry-type transformers, electric motors and coils.
First of all their main strength is their optimal electrical insulation ability. This makes them ideal for use in the aforementioned systems involving strong electrical current.
It is also possible to produce, upon request, a halogen-free, self-extinguishing UL 94V0 version.
All the products meet the European Directive 2011/95/EC restricting the use of hazardous substances in electrical and electronic equipment.
