Plywood formwork

After a resin-based treatment, the plywood sheets are fixed to the wooden frames in order to obtain a variety of sizes.

This type of formwork is not very costly in comparison with wood, if not even cheaper sometimes. Although it is more efficient than wood in some ways – it features a smoother finishing and can cover larger areas.

It can be reutilised far more times than the wooden formworks thus can be used even 20-25 times.

Both plywood and wooden formworks are nearly off the market for they are being replaced by formworks in other materials, more performing and reusable, such as steel. Some plywood might still be found on sites where a lighter structure is required.

Steel formwork

These panels are made of thin steel plates stiffened along the edge by tiny steel angles.

The panels can be manufactured in large amounts, in any desired modular shape or size. The steel formwork is widely used in large projects or where a large number of formwork reuses is necessary. This type of formwork is considered the most suitable for circular or curved structures.

Steel formwork rather than wood formwork – why:
Comax formwork system

  1. Large panel higher productivity (240x330cm);
  2. Sub-measures and compensation elements available;
  3. Large modularity of panels that can be applied both vertically and horizontally
  4. A “Self Compacting Concrete (SCC)” can be used;
  5. Panels can also be used for inclined walls;
  6. Wide range of accessories (corner brackets, service brackets, strutting beams).

With such large panels and just a few accessories, the COMAX system is the ideal solution to facilitate and accelerate formwork operations. It can withstand high pressures and easly adapts to any type of geometry (large-sized walls, pillars of different sections, elevator shafts).

Following a supply of over 5000sqm to an Algerian company, Comax was used for the construction of infrastructural works (motorways, bridges, metro network), specifically for the construction of piers, pulvins (bolsters), bridges and walls.

COMAX DISMANTLING

The key step for the correct reuse of the formwork is a perfect dismantling. Therefore, it cannot occur without precautions:
