Round profiles – fiberglass

Top Glass manufactures Round TRIGLASS® profiles (GRP – FRP- CRP) made in composite material. Our products can be reinforced with fibreglass and/or carbon and they represent one of the wide range of pultruded profiles made by Top Glass.
Furthermore round rods are partially available from stock for prompt delivery and they are intended for use in a wide range of sectors.
They are used as semi-finished bases in construction, in agriculture, for electrical applications, as structural reinforcements and for street furniture.

Similarly round rods are also used in making technical items such as umbrellas, antennas and sport and leisure articles (for example, tent poles, in modelling and kites and as flagpoles or supports for banner advertisements).

Finally their shape and characteristics make them also widely used as reinforcements for sails in the marine sector.
