Circular Hollow Section Sign Posts, also known as "CHS sign posts" are the leading choice for UK highway sign installations. Standard steel posts are hot-dipped galvanised, However our ULTRAGALV posts provide a far superior level of corrosion resistance. ULTRAGALV uses a unique zinc/aluminium/magnesium coating that provides up to 20 times the resistance to the standard hot dip galvanising process.

Our steel posts under 89mm in diameter are specified to BS EN 12767:2019 standard.

CHS Galvanised Post Choice

We currently stock standard 76mm (3") diameter CHS Steel Posts in:

3000mm x 76mm CHS Steel ULTRAGALV

3600mm x 76mm CHS Steel ULTRAGALV

4000mm x 76mm CHS Steel ULTRAGALV

ULTRAGALV - The premium galvanising protection

Our CHS sign posts use a ground breaking galvanising process called ULTRAGALV. This sets a new standard in corrosion-resistant coated steel tube: up to 20 times the corrosion resistance of galvanised tube, the durability of high-strength steel, self-healing anti-corrosion properties, better processing capabilities than post-galvanised tube, plus the added benefit of environmental sustainability.

ULTRAGALV's evolutionary zinc/aluminium/magnesium coating withstands the most hostile conditions, including alkaline and ammonia rich environments. Furthermore, in exhaustive tests conducted by leading UK test house Rotech Laboratories ULTRAGALV lasted the equivalent of 100 years without significant deterioration.

With unique ULTRAGALV weld repair, 100% exterior and interior protection is guaranteed. This, together with ULTRAGALV’s tough scratch-resistant surface, offers extreme product longevity.

Alternative options for Steel CHS sign posts

Where steel sign posts are not specified we also offer Aluminium Sign Posts, Our aluminium range have a premium powder finish which is perfect for business premises, decorative installations and other non-highway related projects. Aluminium sign posts are much lighter and have even higher levels of corrosion resistance in comparison to galvanised steel CHS posts.
