Galvanisation is a method used for coating metal to protect it against corrosion. The surface is covered with a thin layer of zinc. The underlying metal surface is shielded against the environment and only the zinc is exposed to the atmosphere. Once galvanised, the surface does not have to be painted; in fact, the silver
Hot-dip galvanisation is the process whereby steel is given corrosion protection. It entails the dipping of steel in a bath of hot molten zinc to create an even coating over the steel. Through this method, the zinc bonds with the underlying steel to create a strong, durable, and corrosion-resistant surface. Galvanised steel is used in
Although unprotected steel products are cheaper and thus initially more cost-effective than galvanised corrugated steel, one has to remember that unprotected steel must be coated. The coating is all that protects the underlying surface against corrosion. This layer of protection must be maintained. This means having to apply a new coat every few years. The
SANS 121:2000, together with ISO 1461, has been superseded by SANS 121:2011. SANS 121:2000 or rather, the current standard of SANS 121:2011, is the national standard for hot-dip galvanised coatings on fabricated or manufactured iron and steel articles. It covers the specifications and tests for these standards. Accredited hot-dip galvanising plants adhere to the requirements
With the cost of construction and engineering projects always a concern, it is easy to fall into the trap of buying unprotected steel and then coating it with the appropriate protective paint to prevent rusting and degrading. However, galvanising specialists in South Africa adhere to strict international and national standards in terms of the method
When it comes to galvanizers, it is essential to buy from trusted companies such as Armco Superlite, as specific standards for galvanization should be adhered to by these galvanizers. Armco Superlite meets every requirement, what with the company being certified to the BSI ISO 9001:2008 quality standard. This means that Armco Galvanizers ensures that strict customer quality-control management systems are in place for
Although motorists often take guardrails for granted, the barriers are essential for the improvement of road safety conditions. As such, it is imperative that the W-beam guardrails be manufactured according to the requirements of the relevant standards, including SANS 1350:2005. With it being essential to ensure standardisation in the usage of road safety products across
Hot-dip galvanisation makes it possible to protect the underlying steel from corrosion. With the importance of material integrity to ensure the longevity of structures such as culverts, tunnels, and related products widely used in the mining and construction industries, it is imperative to select a supplier known for their focus on quality galvanisation.
