InstallSpecifying the correct Tubes

Our premium Install® Plus 235 hot-finished, multi-certified tube is technically superior to cold-formed alternatives.


The Importance of specifying the correct Tubes

Our premium Install® Plus 235 hot-finished, multi-certified tube is technically superior to cold-formed alternatives.

Therefore, to avoid being supplied the wrong product, it is vital that tubes are correctly specified at time of ordering, and that purchasing documentation and stock is checked to ensure you receive exactly what you have ordered.

This is especially important if a Tata Steel hot finished, GH grade (GH=Get Hot), fully CE certified, traceable and UK supported product is required.

For hot-finished products, always ask for:

  • EN10255/10217-2 (i.e. Part 2)
  • GH grade (i.e. P235GH) – to help remember, GH = Get Hot
  • Tata Steel Install® Plus muliti-cert hot-finished

If you have any questions about how to correctly specify Install® Plus 235 or any other query call the Tubes Technical Helpline on +44 (0) 1536 402121 or email tubesconstruction@tatasteel.com

Our Install® Plus 235 hot-finished, multi-certified tube to BS EN10255 and 10217-2 S/P235 GH (GH = Get Hot) grade is CE marked in accordance with the Construction Products Regulations (CPR) to both CAT3 (fuel and gas) and CAT4 (water).

Some alternative products do not appear to be CE marked correctly, so please be aware of possible application, compliance, warranty and insurance sign-off issues.

All Install® Plus 235 tubes are clearly marked along its length as shown in the illustration below, if it is not question the supplier where you purchased the product.

If checking your stock, our Install® Plus painted products will have the following marked along the whole length tube:

TATA STEEL INSTALL PLUS MULTI-CERT HOT-FINISHED & TATA STEEL INSTALL PLUS BS EN10255-S235GT/S195(G)T 10217-2-P235GH + TST41 CE-CPR-CAT3+4 EW SIZE (QA DATECODE) QA UK.

If it doesn’t say Tata Steel Install® Plus, then it’s not Tata Steel.  It’s not UK manufactured, fully traceable and hot-finished.

Unlike cold-formed alternatives, our hot-finished tubes have:

  • An ordered and consistent microstructure.
  • No internal stress that can promote cracking.
  • Consistent and reliable mechanical properties.
  • Improved structural integrity and ductility.
  • Improved and consistent toughness.
  • Higher pressure integrity.
  • Greater factor of safety.
  • No loss of strength during additional welding or heating.
  • Improved performance against corrosion.
  • Ability to be bent to tight radii without splitting, creasing or collapsing.
