Formwork profiles protected against corrosion

Against corrosion.

Steel shuttering formworks in precast concrete plants require protection against corrosion. This corrosion protection is achieved by means of corrosion-inhibiting additives in the forming oil agent. However, if the application of the forming oil agent to the formwork profiles is inadequate, or if the corrosion protective properties in the forming oil agent are missing, then this will inevitably lead to corrosion of the valuable formwork material. The warm, moist climate in the production environment also leads to cavity corrosion and crevice corrosion, unless the cavities of the formwork profile are regularly protected.

A high and lasting corrosion protection with a high level of resistance to solvents and acids, offers the new corrosion protection system KS from Weckenmann, that has specifically been designed for formwork profiles. The formwork profiles are chemically treated during the dipping process and provided with a highly resistant coating.

Thereby not only the mechanically stressed outer contours of the profiles are protected, but also the corrosion-sensitive cavities in large-scale box profiles, even double layered sheet itself will be effectively protected against corrosion.That way, the high-quality formwork profiles from Weckenmann are optimally protected before leaving the factory for a long product life in precast concrete environment.The thin and extremely robust coating is very compatible with the concrete surface and contributes to a good demoulding of the precast concrete product.

The KS coating system is optionally available for all Weckenmann formwork profile series.

Weckenmann offers for the different requirements in precast concrete plants, 5 formwork profile series which are all optionally available with the KS coating:

• A series
  For the floor slab and double wall production
• M-series
  For the solid parts production with shuttering robot
• New: M-base, M-TOP
  The height convertible series applicable with shuttering robots for the solid parts production
• X-Uni
  The magnetic fixing system for flexible formwork construction with wood
• X-SIDE
  The window and door cut-out system
• X-Base, X-Top
  The height convertible system for manual use
