Welding Before and After Hot Dip Galvanizing A proportion of steelwork that is hot dip galvanized is subject to fabrication by welding prior to dipping. 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

Variations in Galvanising Surface Colour Dark, grey or light grey - it`s all galvanised. Protection is equal - and often better - with dark grey coatings than with light grey. When rimmed or aluminium killed steels are hot dip galvanised, compact zinc-iron alloy layers are formed and covered by zinc, which
Size and Weight of Steel Work for Galvanizing Hot dip galvanising is a process in which articles are immersed in various baths. Most hot dip galvanising is contracted out to specialist firms, which may also be responsible for the transport and handling of the material. Although bath sizes have increased over
Galvanised Containers and Tubular Fabrications Processes in the galvanising plant, such as degreasing, pickling, rinsing, fluxing and actual hot dip galvanising itself involve immersion in baths. It is important therefore that the liquid in the bath can reach into every corner and crevice - even with hollow components. In got dip
Staining and discolouration of galvanised steel Sound galvanised steel with many years of corrosion-free life ahead can sometimes be rust stained or discoloured. This may give an incorrect impression that the coating has failed and is, in some cases, visually unacceptable. This leaflet sets out and illustrates the main caoses of
