Xpa is an expanded metal sheet product specifically developed for use as permanent formwork to concrete. The profit of the open mesh, in combination with the Xpa tangs, allows the development of dense concrete nodules and indents on the face of Xpa , forming an enhanced mechanical key for the second phase pour. In the case of visible elements, the resulting. Xpa surface is suitable to receive a rendered or tiled finish.

Xpa has an enviable portfolio of technical data. Independent bodies have undertaken full-scale testing programs to determine and verify Xpa effectiveness in forming
construction joints. The result is a product with hell-defined engineering properties, establishment formwork pressure characteristics and measured improvement to the joint performance Xpa Form Rib is primarily used in construction joint applications. Still, it is also used to form wall, beam and column surfaces and slab soffits, where the formed surface will not be seen.

For over 80 years has been successfully used as permanent formwork on
innumerable building and infrastructure projects throughout the world.

When Xpa  is used as vertical formwork; the resulting formwork
      pressure is significantly less than that developed with traditional forming
      materials, reducing the overall support requirement.
Xpa joint surface require minimal preparation prior to the next
     pour, with the exception of the rebar cover zone . It minimizes the labour,
     mess and disposal requirements associated with scabbling, chemical
     retarders and jet washing.
A correctly formed Xpa joint outperforms traditionally prepared
     joints in shear and bond.
Xpa reduces the risk of trapped air and void within concrete.
The range of narrower sheet width improves site productivity and
     minimizes wastage.
Xpa is a proven construction product with comprehensive
     technical data, manufactured by a company.
