FAQ's

Galvanised steel is all around us and plays an important role within our built environment.

It is the process by which clean steel is immersed into molten zinc to obtain a coating that protects the steel from rusting or corroding.

The process provides long-term protection, and many other advantages – including durability, sustainability, cost-effectiveness, and reliability – that are sometimes overlooked.

Galvanised steel conduits are typically used for lighting applications, underfloor heating and other high temperature applications.

With this said, galvanised steel conduits are able to withstand extreme temperatures, and have a high load bearing capacity, making them ideal for use in hazardous site conditions in both industrial and commercial sectors.

A galvanised steel conduit is perfect for guiding cables and wiring around the site, especially for areas where impact is likely, as these types of conduits provide some extra protection.

They’re available in lots of different sizes, here at Flex-It, so you’re bound to find the perfect match for your project.

If you’re unsure what size you need, or if this type of conduit is best for your project, get in touch with our team of professionals by calling 01530 812195 or emailing sales@flex-it.co.uk and we’ll be happy to help!

The type of conduit you need will depend on the installation and environment where cables will be routed.

Steel conduits are a brilliant choice for dry indoor locations with vibrating machines, like heating or cooling units, for example.

Liquid-tight metallic conduits, like galvanised steel, are perfect for outdoor use thanks to their waterproof zinc coating.

They do tend to be a little more expensive, but because of the benefits they offer, galvanised steel conduits are totally worth it if you ask us.

Generally, galvanised steel is less expensive than stainless steel, but this doesn’t mean that its excellence is compromised.

Galvanised steel’s defining attribute is its outer coating of zinc, which forms a protective layer against the combination of moisture and oxygen that can otherwise cause rust to form on the underlying metal – making it perfect for outdoor applications.

It’s also a little bit more flexible than stainless steel, whilst still being just as strong.

At Flex-It, our galvanised steel conduits are available in a range of sizes, but the size you require will depend on the application and where your cables will be routed.

If you’re in need of expert advice, get in touch with the team here at Flex-It.
