Frame with 3D ribFrame® technology

Since it was launched, the Langmatz QaBo has redefined the manhole market. The objective was clear: a manhole that would permanently withstand loading. The result is the QaBo – equipped with 3D ribFrame® technology. This innovative rib and honeycomb system ensures even load transfer and perfect structural integrity.

For the load-bearing elements, we use a polycarbonate that meets the most exacting requirements: rigidity and stability, thermal resistance, resistance to UV and weathering as well as chemical resistance. And it is also sustainable – thanks to its multi-recyclability.

Our decades of experience in injection moulding and production in Germany guarantee uncompromising quality. State-of-the-art machines and the most stringent quality controls – from incoming goods inspections to batch monitoring – guarantee a consistently high-quality product.
