GALVANISING FOR FABRICATORS


There’s no other corrosion protection system that provides the long life, durability and reliable performance of galvanising. To ensure optimum results — reduced coating costs, quick turnaround times and safety of personnel — there are a number factors that must be taken into consideration prior to fabrication. These include:

  • Welding Galvanised Steel
  • Hot Dip Galvanised Castings
  • Renovation of Hot Dip Galvanised Steel
  • Vent & drain hole requirements

WELDING GALVANISED STEEL

The welding process can affect galvanizing in terms of coating quality, distortion and creating an increased potential for cracking in isolated instances. By taking suitable actions these issues may be alleviated. Read More…


HOT DIP GALVANISED CASTINGS

Galvanizing of castings is covered by EN ISO 1461:2009. Hot dip galvanizing of cast iron provides excellent protection from corrosion and the coating is applied by immersion in molten zinc at 450°C forming a tough, adherent coating which is bonded to the base metal by series of zinc-iron alloy layers overlaid with free zinc.

RENOVATION OF HOT DIP GALVANISED STEEL

The galvanized coating applied by immersion in a bath containing molten zinc not only provides a high level of corrosion protection but is also very robust, such that it will normally withstand handling and erection. However, the coating may occasionally be subject to small areas of mechanical damage typically as chips at edges or corners when mishandled. In such instances, it is necessary to repair the galvanized coating. Read More…

PROTECTING THREADS DURING GALVANISING

Masking is treating a portion of the steel surface prior to hot-dip galvanising to prevent zinc from reacting with and adhering to the steel. It is not an exact science and is not 100% effective, and as such, additional work may still be required to remove unwanted zinc after galvanising. Read More…
