Shear load reinforcements for lines in flat ceiling slabs

Pipelines laid in flat ceiling slabs weaken the load-bearing cross-section of the ceiling considerably, so shear load reinforcement generally has to be provided.

The DURA Box shear load reinforcements allow more than 100% of the shear strength of the undisturbed flat slab to be achieved.

DURA Box enables more economical slab thicknesses and clear line routing. DURA Box line cages are quick and easy to install.
