When purchasing a fence there are many choices to make in terms of style, safety and durability. All of these are important aspects that play a role in varying degrees. Equally important is the method of galvanizing. Reliable hot-dip galvanized products are often chosen. So why make concessions in this area if the alternative – pre-galvanized products – are of equal quality, go through a more environmentally friendly process and are also cheaper?
For certain applications, the standards require that there should be no blemishes on the product that people can be hurt by. This includes railings or fencing in playgrounds or on school yards. Our pre-galvanized fencing meets the requirements of a smoothly finished product. With pre-galvanization, zinc accumulation, droplet and membrane formation is minimised.
When fencing is raised again after full immersion in a zinc bath, significant waste zinc drips off. Sharp drainage spikes and zinc deposits are then inevitable. Pre-galvanization, on the other hand, ensures a more compact and efficient zinc layer, resulting in a smoother surface.
The amount of zinc required for pre-galvanizing is up to 75% lower than with full-bath galvanizing. Transport costs are reduced, because deliveries of steel products to the galvanizing plant are now obsolete. Moreover, the pre-galvanizing process reduces the production lead time because the pre-galvanized product can be coated directly. These cost savings result in a lower purchase price.
By opting for a pre-galvanized fence, the CO2 output of the galvanizing process is reduced by up to 70% compared to hot-dip galvanizing. A substantial reduction in transport movements, a reduced amount of zinc and approximately 15% less chemical consumption yield the largest part of the saving.
Wind, snow, rain, bright sun. Fences are exposed 24/7 to changing weather conditions. In addition, the environment in which the product is installed also influences the lifespan. As a result, for example, of the presence of salt in the air of a nearby coastline, chlorine and sulphate precipitation in industrial areas and along railway lines, or the ammonia emissions from a nearby farm. Pre-galvanized products have been extensively tested for corrosion resistance and meet corrosion class 5 (C5 with epoxy coating plus polyester powder coating).
Fences with the longevity of a house. You can be confident that they will still protect your site year after year. Thanks to a specialised galvanizing process, our fencing is resilient against atmospheric corrosion / rust formation, free from sharp edges, and has greatly improved protection against surface damage. This process is more environmentally friendly, without compromising on quality.
