Could Have Should Have Galvanized

Our ‘Could Have Should Have’ campaign aims to highlight the extensive amount of corroding steelwork across the UK and Ireland. Protecting steelwork correctly on day one can help to save money spent on replacement or maintenance, which can be much more expensive than the intail cost of protection. An even more important aspect of correct corrosion protection is the contribution it can make to a more sustainable built evironmental.

It is estimated that nearly 4% of global GDP is lost to corrosion annually across the world.

The Thing About Rust

Steel Corrosion

Steel Corrosion Time Lapse

Have you ever wondered what is going on with rusty steelwork? Why it happens and even what it is exactly?

The reason rust presents so often in our built environment, infrastructure and industrial projects, is largely due to the strengths not the weaknesses of steel, perhaps our most popular construction material.

As the backbone of most modern industrial economies, steel is versatile, flexible and strong, a vital national asset that benefits from being protected from day one, because as soon as you expose steel to the elements, it begins to corrode.

The solution to rust

With a bit of initial forethought, protecting your steelwork by hot dip galvanizing not only offers long term corrosion protection, but also helps to protect what is a vital asset. Galvanized steel can also be reused or recycled within existing steel recycling processes.

Three reasons to galvanize

    1. It’s proven.
      There are innumerable examples proving the performance of galvanized steel in many environments, industries and applications. Check out or case studies
    2. Lewis Glucksman GalleryIt’s sustainable.
      The long-term durability provided by galvanizing is achieved at relatively low environmental burden in terms of energy and other globally relevant impacts.
    3. It’s fast
      The actual process of dipping steel in molten zinc takes just a matter of minutes. What takes a bit longer is the preparation of the steelwork and in practice there is a lot of other work being processed at the same time. So the typical turnaround time is about three days. By arrangement, however, galvanizers can offer a 24 hour turnaround. Find your local galvanizer
