Our technologies

Since 1963, Top Glass has made its composite products using systems designed and built entirely inside the company.
This has been possible due to the exclusive know-how which it has developed over the course of its fifty-year history.
The three main technologies used are Pultrusion, Centrifugal Casting and Pullwinding.

productive processes

Pultrusion technology

Pultrusion s a equivalent technology of extrusion for making straight profiles without length limits.
It produces unique results that are aimed at users who need composite profiles with high performance in a longitudinal or lengthwise direction but it offers also enhanced characteristics in directions other than longitudinal thanks to reinforcements in the form of fabrics.

Centrifugal casting Technology

Centrifugal casting is a production technology used to make composite poles in the shape of a truncated cone with maximum length, set only for logistical constraints, of 13.6 metres. This technology makes it possible to make products with a high degree of dimensional and physical-mechanical repeatability. These poles find wide use, for example, as lighting poles and supports for electricity, telephone and over-head lines.

Pullwinding Technology

Pullwinding technology is used for producing tubular profiles with superior rigidity and mechanical resistance. Pullwinding, used to create tubes, differs from traditional pultrusion in that it uses both roving placed longitudinally and circumferentially with respect to the profile's axis in order to obtain superior rigidity.
