Tata Steel products were specified for the £35 million roof refurbishment at London Victoria.

The Grade II-listed original roofs over the Eastern “Kent” side of London Victoria Station had protected travellers for 150 years, but required extensive renovation. Network Rail commissioned an up to the minute solution, complementary to the original design, featuring 10,000m2 of Tata Steel products.

The roof refurbishment at London Victoria presented special challenges, as Alan Clarkson, Project Manager for main contractor May Gurney, explained.

“This was a complete structural refurbishment, not just cosmetic. We were working to original 1860’s drawings, which were all found to be incorrect as the work progressed.

“The biggest challenge was in enabling the station to continue normal operation during the refurbishment, isolating it from the roof works.

Installation contractor Everlast Waterproofing Limited fitted R46 profile to the two approximately 40 metre span, over 100 metre long main barrel-vaulted roofs, to a 26 metre radius curve, incorporating stippolyte obscure glazing, to match the original patent glazing system.

The replacement roof featured R46 profile in double-sided Colorcoat HPS200 Ultra®, with a Goosewing Grey finish on the external face and a Straw finish on the internal face.

The R46 profile was selected by Network Rail due to its ability to span approximately 2.8m from purlin to purlin.

On the concourse, the existing felt roofing laid on timber purlins was replaced by steel purlins and C19 profile in Colorcoat HPS200 Ultra® in Goosewing Grey, laid over purlins at nominal one metre centres, with an internal PM13 profile inColorcoat HPS200 Ultra® in Straw, providing a like-for-like tongue and grooved boarding effect when viewed from the underside. The existing translucent corrugated sheeting was replaced with stippolyte glazing mounted within a patent glazing bar system.
