Hot dip Galvanizing has been used for many years to protect components an cars and trucks. At first it was used only on low volume, specialist makes such as Rolls Royce, Land Rover and Lotus. BMW used it on the ZI, precursor to that Z3. However, the consumer driven requirement for longer and longer anti-rust […]

Steel and concrete are the most important materials in the construction of multi-storey car parks. They are frequently used in combination with each other. For example, the steel structure can be used together with a composite floor of steel. Steel can be readily recycled. Galvanizing does not reduce this recyclability. Zinc too can be recycled.

The modern urban landscape contains many different types of balcony. They can bring a marked improvement in quality of life – particularly in residential housing. They offer additional space for leisure and relaxation in the open. They can become oases of peace, relaxation and repose, not only in the centres of towns or in the

  Q: We recently had to carry out some remedial work on site, prior to erecting a Hot Dip Galvanized steel structure. The architect on the job was concerned that we might have intrinsically damaged the corrosion protection of the steel. Is this the case? What is the repairing galvanised steel process? A: Small areas

Galvanized steelwork can be subject to staining and discolouration which can sometimes be mistaken for failure of the coating and rusting of the base steel. There are numerous reasons why such staining may take place and there are summaries below. Surface Contamination One of the most common causes of discolouration is general surface contamination with

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

Hot dip galvanizing provides a high level of corrosion protection due to the slow rate at which it corrodes in an atmospheric environment. Part of the protection is provided by a zinc carbonate patina, which forms on the galvanized surface over a period of time by reaction of atmospheric carbon dioxide with a thin layer

When two dissimilar metals come into direct contact and an electrolyte such as moisture is present, a battery cell is created and an electrical current flows. This causes the more electronegative or anodic metal as determined from the electro-chemical series (see below) to corrode more rapidly. This means that galvanizing being a zinc coating will

Specifying Hot Dip Galvanized Steel For the vast majority of applications, hot dip galvanizing can be simply specified using the following reference: Hot dip galvanized to BS EN ISO 1461 : 2009 by a member of Galvanizer Association (Galco, Sperrin). This standard contains coating thickness requirements as shown in table below which will typically be
