Founded in Milan in 1963, Top Glass has always nurtured its own internal technological know-how for making composite profiles.

The first items manufactured using pultrusion in the United States arrived in Europe during the early 1960s. It was still a nascent technology and much remained to be understood, developed and engineered in order to enable production on an industrial scale. With the passion and tenacity that have been its core values to the present, Top Glass successfully met its first challenge: to single-handedly design and make one of the first European machines for producing pultruded profiles.

Top Glass has been producing profiles from that day to this. It quickly became globally renowned and appreciated for its steadfast commitment to innovation.

Top Glass created a toolroom for manufacturing pultrusion moulds. A centrifugal casting process for the mass production of fibreglass poles, production lines for thermoplastic matrix pultrusion and pullwinding were also implemented. All these activities have relied exclusively on the company’s internal research and development centre.

For more than three decades, Top Glass systems and technology have been internationally recognized for both their productivity and product quality.


The Top Glass Company was founded in Milan with the aim of manufacturing glass fibre reinforced plastic products.


Pultrusion was still a fledgling technology and full-scale industrial grade production had not yet begun. In this year, Top Glass took on its first challenge to implement in-house design and construction of Europe's first machines for the production of pultrusion profiles.


Having consolidated the technology and following the construction of several pultrusion machines in its Pioltello factory, the Top Glass Technical Office faced a new technological challenge: the development of a new production process and the installation of the first centrifugation line for the production of truncated-cone fibreglass poles that are now widely used for the public lighting of numerous municipalities as well as by the FFSS (Italian State Railways) and TELECOM.


Top Glass had been working with ATM (Milan's Municipal Transport Company) and the Milan Metro since 1977, testing the first fully-insulated fibreglass support systems for metro-rail electrical lines. Significant savings were achieved in material and labour costs, both during installation and subsequent maintenance.
In 1983 the experimental phase was completed and these materials were approved under the CEI-UNEL 73664 standards. Since then, thanks to the properties of TRIGLASS® profiles, the TOPSYSTEM solution has been officially used in the metro railway system throughout northern Italy.


In this year, Top Glass specialised in the production of car radio ANTENNAS which immediately spread throughout markets worldwide.
Fibreglass is transparent to radio frequencies and provides a resistant and flexible mechanical support to the internal copper conductor which can thus perform its reception function undisturbed while protected from chemical and/or atmospheric damage.
The same physical and mechanical characteristics allow TRIGLASS® profiles to be used in modern Radomes to protect the antennas of mobile cell phone systems.


After 25 years of consolidated experience, Top Glass continued to specialise further in the production of complex geometry profiles. The company enjoyed successful growth in the increasingly demanding domestic market and achieved its first important results in Europe.
The large demand for TRIGLASS® profiles drove the company's expansion and the new Pioltello plant was built on a 9,000 square metres site area.


By now, research and development had gone beyond the machinery and equipment required for TRIGLASS® profile production. The technical department is constantly engaged in pursuing innovative solutions for the use of new raw materials. Thus, for the first time, a specific composite material was developed that complies with very strict specific fire resistance parameters and related fume emissions.
It was an outstanding success, the first significant penetration of the European market: over 2,000 tons of TRIGLASS®, equivalent to 450 km of cable duct, were supplied for the construction of the Channel Tunnel (Eurotunnel).


Top Glass designed and engineered the thermoplastic pultrusion process under the brand name of Fulcrum®.
This great innovation extended the scope of composite profiles to include in-line over-extrusion with different materials, bright colours and subsequent thermoforming. These new products are also characterised by very high mechanical performance, great rigidity and impact resistance.


By this time, Top Glass had become a leading European player: superior professionalism, strong dynamism and flexibility of service drive the company's export-oriented success.
This led to the building of a new production facility in Osnago, with a surface area of 12,000 square metres.
This plant houses modern pultrusion lines, a synthesis of experience and a high level of mechanical and chemical technology innovation as well as expertise in data processing and control techniques.


The Italian 2009 earthquake caused extensive damage throughout the L'Aquila area.
The Church of S. Maria di Paganica was badly struck by the destructive force of the earthquake. Only part of the original structure survived, for which we designed and built a cover to preserve and protect the remains. It is entirely composed of TRIGLASS® fibreglass profiles, an ideal solution due to the intrinsic physical and mechanical characteristics combined with lightness.


In addition to celebrating 50 years of market presence, we achieved the following important goal:
• international business covered 70% of total sales
• more than2,000 customers served
6,000 km of profiles produced in the year
• sales in 25 different countries
• a catalogue listing of 750 standard sections
100% European origin raw materials


Top Glass is today one of the leading and most qualified manufacturers of pultrusion composite profiles.
The particular quality of TRIGLASS® solutions and their suitability for specific applications are the result of decades of experience combined with continuous and passionate technological research.
With our unique design and production capabilities, Top Glass is set to tackle future challenges by constantly pursuing our corporate mission: our technical skills and extraordinary passion will successfully promote the use of composite materials and our TRIGLASS® profiles in an ever-increasing number of fields and applications.


The company’s vision has been clear and defined from the start.
Its objective is to allow architects, engineers and designers to use pultruded profiles and composite materials in the same way as they would traditional ones such as wood, aluminium, steel and PVC.


The mission is to offer customers our technical expertise and the extraordinary passion that drives it. We focus our attention and effort on understanding customer problems and needs and helping them achieve success. We do this whether it involves using TRIGLASS® or other technologies available through our extensive network of contacts.
