In this EPD, Hill & Smith Barrier (steel) products manufactured by Hill & Smith VRS are represented by the ‘Dudley SS N2 W2 3.5 m CEGRSB121’. This product comprises galvanised steel components including posts and/or brackets (depending on fixing type), lengths of barrier and bolts used to make up one linear metre of Hill & Smith Dudley SS N2 W2 3.5 m CEGRSB121 Barrier. This product variant is the most commonly installed and therefore chosen to represent the product group.
Hill & Smith Dudley SS N2 W2 3.5 m CEGRSB121 Barrier (steel) is a single-sided vehicle restraint system consisting of traditional W-profile beams in a W2 width (0.8 m) and C-profile posts with a 3.5 m post spacing. Posts can be installed into soil (standard, long or extra long driven), cast in, socketed or surface mounted. The representative product is standard driven. The Dudley SS N2 W2 3.5m CEGRSB121 barrier system has a containment class of N2 (EN 1317-2 normal containment), an impact severity level B, normalised dynamic deflection 0.7 m, and resistance to snow removal class 3. Normalised vehicle intrusion is not applicable. Pre-galvanised ZM steel components conform to EN 10346 and S355 galvanised components conform to EN ISO 1461.
The product variants within the group are essentially the same, but the mass of material changes due to e.g. post spacing, post length, single versus double sided etc. The mass of the representative product is towards the lower end of the mass range (see additional environmental information), however, it is still considered representative of the product group as this is a typical configuration installed in the UK. The differences in mass between product variants cause the variation in environmental impact between variants of the group to be large.
