Varmforzinket stål i arkitekturen

Traditionelt set har man først og fremmest valgt varmforzinkning på grund af den lange vedligeholdelsesfri levetid, men i dag ser vi stadig flere anvendelsesområder, hvor arkitekter vælger varmforzinket stål af æstetiske årsager. De rå metaloverflader skaber meget attraktive kontraster, når de kombineres med f.eks. træ eller glas. Den øgede interesse for miljøspørgsmål er et andet argument, som taler for varmforzinkning som korrosionsbeskyttelse. Varmforzinkning giver den konstruktion, processen beskytter, en meget lang levetid, hvilket sparer både materialer og energi. Det faktum, at en varmforzinket overflade sjældent eller aldrig kræver vedligeholdelse, bidrager yderligere til den miljøvenlige profil.


Eksempler på bygninger med varmforzinket facade

Nedenfor er vist nogle eksempler på bygninger med varmforzinket facade.

Stockholmsmässan International FairsSweden

The Stockholmsmässan International Fairs in Älvsjö is one of the world’s leading organizers of meetings with 10,000 exhibitors and 1.5 million visitors annually. Alessandro Ripellino/Rosenbergs Architects’ latest addition to the premises is a new multifunctional space intended for conferences and large exhibitions – the AE-hall.

The whole building is wrapped in a facade screen comprising approximately 1500 semi-perforated galvanized steel panels. They form a giant metallic basket with an embossed effect which is intensified by lighting fixtures that are integrated in the galvanized steel structure.

The hall is connected to the existing complex by a gallery which has also been remediated, with new mirror-like ceilings and greenery walls. Galvanizer: Häfla Bruk AB.

Lomma Library, Sweden

Henrik Jais-Nielsen Mats White Arkitekter AB has created a building, between the existing center and a new district by the sea, with a key position in the cityscape. The library building is simple in form, fully clothed with hot dip galvanized steel sheets it differs from all of its immediate surroundings, but associate with the port environment with boats and shacks. The building is located on an elevated granite plateau with an entrance ramp across its width. Heating coils with glycol enters the zone of snow and ice-free – good for parquet floors in the library. Far ahead towards the water and the view is a smaller detached café building, an architectural “little brother” to the library, from where it can also be accessed. Galvanizer: JIWE Varmförzinkning AB.

Quarter “De Gamles Vänner” Enskede, Stockholm, Sweden

The project consists of four houses along Gamla Tyresövägen in Enskede in south part of Stockholm. The houses are turning their short side to the street to provide as much contact as possible with the forest slope above. The facades are performed with 3 mm galvanized steel plates. Architect: Joliarc.

Fishermen wharf warehouses in Cangas’ Harbour, Pontevedra, Spain

A building made of galvanized steel, evoking shipbuildings, providing the necessary flexibility during its constrution and maximum reuse of the material its build of. Rectangular hollow shape structure defines the volumes and modulates closing sheet metal to support them. Lattices in different degrees of density provides unity to the building. The sheets of front (2000x1000x10 mm) were prepared by welded L profiles, so that they could be hung on the omega shapes fixed to the structure and in order to avoid possible deformations in the process of hot-dip galvanizing. The cover is formed also by sheets on U profiles that allow the water evacuation by means of small gargoyles. Lattice panels formed by electro-weld grids (30×10 and 40×10) have been used, depending on the savedlight, with changeable of 60 and 102 (measures of standard manufacture) in order to obtain diverse graduations of transparency to the set.

Karlstad Brigade Museum, Sweden

The 3 mm steel plates were cut in diamond shape and then hot-dip galvanized. The plates were mounted to the wall by overlap screwing at the top. The buildings were finished in August 2012. Steel work: Weland Stål AB. Galvanizer: Zinken Weland  Ulricehamn AB.

IKEA store in Copenhagen, Denmark

The plates in this facade was galvanized 1992-1993. The original coating size was 80-85 microns. Today it is about 70 microns left. The building is located close to the motorway to Helsingör.

JYSK store in Roslilde, Denmark

The plates in this building, JYSK store in Roskilde, are galvanized by DOT, Dansk Overflade Teknik A/S.

New Technical School in RoskildeDenmark

Ringsted PoolDenmark
