PUR beams for blocking and supporting piping
Dan-iso's PUR beams are designed for safe and flexible support of buried district heating pipes and pre-insulated pipe systems. They are used for temporary positioning before welding and as support during installation until permanent supports are installed. The PUR material deforms in a controlled manner - that is, the beam gradually adapts to the load without losing its function. This makes it possible to leave the beams under cover, unlike wooden battens, which must be removed.
The beams are made of hard PUR with high compressive strength, low weight and high chemical resistance. The material is approved according to EN 253 and has the same mechanical properties as the insulation on district heating pipes, ensuring optimal compatibility. The PUR beams can also be used for storing steel pipes and other items where stable and gentle support is desired.

Application
Application
PUR beams from Dan-iso are primarily used for blocking and temporary support of buried district heating pipes and pre-insulated pipe systems during installation. They ensure correct positioning before welding and can remain under the pipes after covering, as the PUR material deforms in a controlled manner and adapts to the load without losing its function. The beams are also suitable for storing steel pipes and other items where stable and gentle support is required. In situations without special requirements for load-bearing capacity, the PUR beams can replace traditional wooden battens. In addition, the beams can be adapted to uneven terrain by turning them upside down, which provides extra height and flexibility.
