  • Best corrosion protection on the market,
  • Manufactured to BS845-2:2003,
  • Extensive range to suit every requirement,
  • No exposed edges or welds.

Corrosion Protection

All Supergalv steel lintels are protected by hot-dip galvanizing the complete lintel after fabrication. This process out performs all other protection systems by:

  • Fully protecting every surface, cut edge and weld with a metallurgically bonded zinc coating, where other systems actually remove zinc during fabrication and do not provide full protection to all surfaces
  • Creating a build-up of zinc coating at the most vulnerable points (edges etc.) which are more susceptible to damage on site and are the least protected in other systems.
  • Depositing a minimum zinc coating thickness of 65um in a metallurgical bond over the base steel.
  • Optional 'Ultragalv 2000' (U2k) corrosion protection system. This achieves a coating thickness of 150um by shotblasting the steel prior to galvanizing. This is up to 7 times more Zinc corrosion protection than other lintels, and the life of a Zinc coating is directly proportional to its thickness.
