Polycarbonate manholes QaBo
Quality: Made in Germany
Manholes are the central components of the energy, telecommunications, and broadband infrastructure. Traditionally,
concrete manholes are predominantly used for this worldwide – primarily from historical habits or local availability.
However, the following increasingly applies from a technical and economic point of view: modern polycarbonate (PC)
manholes are significantly superior to concrete manholes.
Langmatz polycarbonate manholes are designed as cable draw manholes for telecommunications and energy distribution
and have been used in civil engineering since the 1990s. Today, they represent a European gold standard for polycarbonate
manholes.
Langmatz QualityBox polycarbonate manholes have evolved to become a global product. It was time to develop a
corresponding brand name. Hence QaBo – with “Qa” standing for the quadratic elements in every QaBo frame,
underscoring its characteristic design. Its proven quality and functionality naturally remains unchanged.
