Pre-galvanised vs Hot-dipped galvanised vs powder coating is what you should be thinking of when you purchase steel products. Much like you would not choose to wear an anorak in the Arctic, you would not leave your steel mesh decks un-coated. An un-finished mesh deck would not be up to the job. At QTS, we take pride in providing you with the best possible warehouse solution, which is why we have a range of finishes available depending on your needs. There are three main coatings that we offer here at QTS and the use of them is dependent on their application.


Pre-galvanised steel is produced by running carbon steel wire through a bath of Zinc. When it comes out the other end, the excess zinc is removed to produce a smooth finish. Coating thickness may vary with grade and strand diameter. This provides a barrier against the elements that cause the corrosion when mixed with the iron in the steel. This is a good choice for the most typical warehouse applications. Pre-galvanised is our standard finish on our decks and these can be purchased straight from our online shop.

Benefits of pre-galvanised steel:

  • Improved corrosion resistance
  • Cost effective
  • Better appearance for a longer time (reduced rusting)
  • Increased pressure ratings


Hot-dipped galvanised

Hot-dipped galvanised products involve a deep chemical cleaning prior to the coating process. This allows for stronger bonds to form between the steel and the zinc coating. This process is always done at the end of the production process so there will never be any exposed areas of steel which increases its life span. Hot-dipped is highly recommended for use in cold and damp environments as it will not loose its structural integrity in these conditions. Pre-galvanised is not as robust in these conditions.

  • Corrosion protection
  • Increased durability over standard pre-galv
  • Greater hygiene
  • Less maintenance


Powder coated

Powder coating is a dry finishing process that is used to finish all our storGUARD and rackGUARDIAN products and can also be added to our mesh decks. This method is often the preferred choice when the aesthetics of the warehouse is a concern. We typically powder coat all of our products in a RAL 7042 (traffic grey). However, we can offer any RAL colour at an additional price; this can be a handy way to get your branding across in your warehouse.

  • Corrosion resistant
  • Long lasting
  • No maintenance
  • Aesthetically pleasing

QTS can supply all of these coatings on your products. We purchase in pre-galvanised steel as standard and have an in house powder coating machine. Hot-dipped galvanisation is a process that we outsource so may increase cost and lead time. Get a quote from one of our sales team now
