Polyester enclosures


In the process of producing polyester enclosures exist two elements, which have a substantial impact on the quality and repetition of made goods.

  • Material – from which are made elements are thermo-enhanced polyester reinforced by glass fibre. Technologically advanced high quality base product guarantees high mechanical endurance and limits the harmful impact of UV rays.
  • Form – from which depends quality, exactness, and repetition of particular elements of enclosures. Obtaining high quality forms is possible thanks to a richly equipped tool-room in modern machine tools numerically steered and qualified specialist in this field.

  • Lacquered enclosures. Polyester enclosures can be additionally secured by coating the outer covering of any RAL colour. Additionally coating protects the surface casing from UV radiation and abrasion phenomenon. Surface covered with varnish also allows adjustment to the colour of the environment in which housing will be located. Applied two-component coating provides long-term protection against adverse weather events.
  • Anti-graffiti enclosures. The outer surface of the polyester enclosures can be further protected with anti-graffiti means. We currently have a number of solutions and resources that protect the surface from devastation in the form of unwanted prints and other dirt surface. Transparency of the protective measure allows for use directly on the plastic and painted surfaces without affecting the color of the enclosures.
