Centrifugal method

A particular advantage of the centrifugal (spinning) process is the production of longitudinally pre-stressed concrete products, such as posts, poles and pressure pipes. During the centrifugal process, the mould with the fresh concrete is set into rotation. This affects on the concrete mass a centrifugal force, which presses the concrete outward to the mould wall. This delivers a typical grain structure of a concrete texture with outmost density and  minimum pore volume.

The advantages of the Centrifugal method:

  • Higher density through a very high concrete compaction
  • Closed smooth surfaces of the products
  • Exact length and outer diameter by full mould space
  • Suitable for the production of longitudinally pre-stressed concrete products with excellent structural qualities

The perfect solution for the
production of dry-cast concrete
