Recess tubes for the production of precast concrete elements: Efficient solutions for precise concrete elements Discover our high-quality recess tubes, which offer a cost-effective and technically optimised solution for the production of precast concrete elements. These pipes are perfectly suited for culverts for supply lines, conveyor belts, machine anchoring and foundation formwork. Manufactured from corrugated profiled steel strip, they offer the necessary strength for demanding applications. During the construction of concrete elements and precast concrete parts, the recess tubes are positioned and fixed at the planned locations before the concrete is poured. If necessary, suitable protective measures must be taken to prevent the concrete from penetrating the ends. The pipes are then embedded in concrete. Sufficient covering of the recess pipe with concrete must be ensured.

Recess tubes for the production of precast concrete elements: Efficient solutions for precise concrete elements Discover our high-quality recess tubes, which offer a cost-effective and technically optimised solution for the production of precast concrete elements. These pipes are perfectly suited for culverts for supply lines, conveyor belts, machine anchoring and foundation formwork. Manufactured from corrugated profiled steel strip, they offer the necessary strength for demanding applications. During the construction of concrete elements and precast concrete parts, the recess tubes are positioned and fixed at the planned locations before the concrete is poured. If necessary, suitable protective measures must be taken to prevent the concrete from penetrating the ends. The pipes are then embedded in concrete. Sufficient covering of the recess pipe with concrete must be ensured. Our high-quality recess pipes - also known as spiral ducts, corrugated ducts or recess pipes made of steel in round, rectangular or square shapes. We offer you the perfect solution for a wide range of applications. Our spiral ducts impress with their robust design and high stability, while the flexible corrugated conduits can be optimally adapted to various requirements.

Recess tubes for the production of precast concrete elements: Efficient solutions for precise concrete elements Discover our high-quality recess tubes, which offer a cost-effective and technically optimised solution for the production of precast concrete elements. These pipes are perfectly suited for culverts for supply lines, conveyor belts, machine anchoring and foundation formwork. Manufactured from corrugated profiled steel strip, they offer the necessary strength for demanding applications. During the construction of concrete elements and precast concrete parts, the recess tubes are positioned and fixed at the planned locations before the concrete is poured. If necessary, suitable protective measures must be taken to prevent the concrete from penetrating the ends. The pipes are then embedded in concrete. Sufficient covering of the recess pipe with concrete must be ensured. Our high-quality recess pipes - also known as spiral ducts, corrugated ducts or recess pipes made of steel in round, rectangular or square shapes. We offer you the perfect solution for a wide range of applications. Our spiral ducts impress with their robust design and high stability, while the flexible corrugated conduits can be optimally adapted to various requirements.
