Infrastructure & Construction Products

We manufacture high-strength and long-lasting composite solutions for urban infrastructure and construction projects.
Thanks to our FRP (fiber-reinforced polymer) technology, we provide products with high load-bearing capacity, corrosion resistance, and electrical insulation properties.
We are your reliable partner with custom design and production services tailored to your project needs.

What Do We Produce?

  • Manhole covers and stormwater drainage gratings

  • Underground infrastructure protection panels

  • Cabinet inner components and safety lids

  • Pipe and duct protection systems

Why Choose Composite?

  • Excellent resistance to corrosion and chemicals

  • Lighter than metal → easier transportation & installation

  • Electrically non-conductive → safer usage

  • UV and harsh weather-resistant structure

  • Long service life with minimal maintenance

  • Anti-theft advantage (no metal value)

Why Choose Us?

  • Composite manufacturing experience since 1986

  • European-standard quality → EN & ISO 9001 compliance

  • Rapid prototyping → fast transition to serial production

  • Strong partnerships with municipalities and contractors

  • Custom engineering support for unique project needs
