Kalzip bridges the gap between form and
function
Kalzip's stucco embossed standing seam is part of roof one of the most prestigious toll canopies in Europe runs alongside the Tamar [road] Bridge.
The chosen material used to roof 'one of the most prestigious toll canopies in Europe' had to be robust enough to withstand an extreme environment, flexible enough for the complex design and aesthetic enough to please the occupants of the 50,000 vehicles that use it every day Kalzip's stucco embossed standing seam ticked all those boxes and more for Harris McMillan architecture + design who conceived the new canopy which combines a contemporary look with reflections of Brunel's' cylinder girder railway bridge that runs alongside the Tamar [road] Bridge

Corus Kalzip win contract to supply Hi-Point - Corus' innovative Off-Site roofing system - for campus buildings at Mid-Kent College in Medway, Gillingham.
"These could have been mounted on a simpler frame structure but the client decided to put a new canopy over the roadway and booths which would also carry the tag readers," said Robert Harris of Harris McMillan.
"Because of the historic importance of the railway bridge, a well-conceived and striking architectural treatment of the visible structure of the toll plaza was vital".
"We designed the canopy using three dimensional computer models and came up with a double curved segmented roof".
We considered various covering materials for this and involved technical staff from Kalzip at an early stage.
They confirmed that their cladding systems could cope with the complex design and we were impressed with the attractive options available".
"The structure is subject to extreme weather conditions and also to fumes etc from constant traffic".
"The material will withstand all these".
"The client was delighted with the elegant design we produced which while being fully contemporary, contains some deliberate subliminal echoes of Brunel's bridge".
"The client is also very pleased with the finished product".
"We have specified Kalzip previously and would certainly do so again".
The use of Kalzip on the double curved roofs necessitated some complex steelwork for the secondary support elements and a challenging working environment for roofing contractor Bowline Roofing and Netting for main contractors Dean and Dyball Construction.
Managing director Tony Marsh said: "We feel it is a fine example of the flexibility of Kalzip".
"The whole project was achieved without the requirement for any welding to create the tapers and curves".
"With the correct product we have been able to provide a robust and aesthetically pleasing structure to our client who was overjoyed with the finished result".
