A PIONEERING PROJECT: THE CALWER PASSAGE

GREEN CORROSION PROTECTION FOR A GREEN FACADE

210 tonnes of galvanized and powder-coated steel were required for the construction of the front facade of the Calwer Passage in Stuttgart. ZINKPOWER Meckenheim delivered on time and also made its own valuable contribution to the sustainability of the new "green" building.

THE NEW CONSTRUCTION OF THE CALWER PASSAGE: A PIONEERING PROJECT

The fauna here not only provides decorative detail, but with the planting of entire hedges, shrubs and even small trees is a key component of the nature-is-sustainable concept. The supporting structure for the greenery is located in front of a highly insulated glazed facade. Green facades offer a whole range of benefits: They reduce noise, sound and fine dust, increase biodiversity and improve the air and ambient quality.

ZINKPOWER MECKENHEIM IMPRESSES AS A PARTNER

It is consistent with this conceptual orientation that the building owners have opted for corrosion protection from ZINKPOWER^® in favour of sustainability factors. The demands on sustainable production processes were extremely high. One of the decisive factors in obtaining the order was the high environmental standards of ZINKPOWER Meckenheim's production plant. Closed-loop systems, heat exchangers and state-of-the-art filter systems are a basic requirement for our galvanizing group in the operation of every site worldwide.

The order volume included corrosion protection for 210 tonnes of steel for the supporting structure at the front – including trough holders and maintenance walkways as well as the grating.

DUPLEX COATING WITH ZINKPOWER COATING PREMIUM

With the choice of ZINKPOWER Coating Premium, the corrosion protection required for corrosion category C5-M could be guaranteed with long-lasting colour reliability. Although there was no increased atmospheric pollution in this case, it was necessary instead to protect the supporting structure of the planters from influences caused by the automatic irrigation and the plant fertiliser additives.

Incidentally, even when they are dismantled, the steel parts used can be recycled at any time without any loss of quality. For the "green" operator of the Calwer Passage, this means that the sustainable conservation of resources as well as energy and CO2 savings can be combined in the best possible way!

The Calwer Passage

Located in the heart of the city of Stuttgart, the Calwer Passage became established as a lively shopping centre soon after its completion in the mid-1970s. The glass dome of the passage set an architectural highlight and created a unique shopping atmosphere. The listed status given to the dome made the decision to construct a new building a difficult challenge.

The public is even more interested in the innovative facade design of the new building than in the preservation of the dome. This is because "green" has been made the dominant facade colour. The intensive greenery of the entire facade areas and the flat roof is intended to shape the inner cityscape along Theodor-Heuss-Straße in the most natural way possible and allow the passage to literally grow and flourish.
