Musée Confluences

Visual Impact of Stainless Cladding

The Musée des Confluences is a science centre and anthropology museum opened in 2014 in Lyon, France.

It is also a stunning example of the beauty and agility of stainless steel. This already iconic building, designed by Austrian architects, Coop Himmelb(l)au, represents the union of a glass crystal and a stainless steel cloud. It is the use of a layer of stainless steel to cover the cloud that allows it to reflect light and colour; encapsulating echoes of the sky and the city, as well as the water and the greenery.

Beauty and agility at work, this combination of cladding along with the stark shape of the building gives Musée des Confluences its stealthy appearance that may be accentuated under its shell or diluted in the light, creating the impression of a solid behemoth or a soft cloud.

Paneum – Wunderkammer des Brotes

If you happen to be in the Austrian village of Asten, you simply can’t help but notice the shiny, futuristic PANEUM building. The four-story building was commissioned by Backaldrin, a local flour and baking ingredients company, to house its information center, exhibition venue and even a museum on the history of bread.

Designed by Coop Himmelb(l)au, the building is comprised of two structures stacked on top of one another. The lower ‘box’ is made of bare concrete and houses the entrance and special event space.

This contrast strikingly with the metallic bubble that floats on top and houses the main exhibition galleries. Called the ‘Wunderkammer des Brotes’, this top level is comprised of a glue laminated timber structure cladded with Aperam Stainless Steel shingles (Aperam 316L bead blasted, 1mm thickness), which give the building its iconic shine.

Opened in 2017, the exhibition brings the history of bread to life through a collection of over 1,200 objects that date back 9,000 years.

MRC Laboratory of Molecular Biology

The MRC Laboratory of Molecular Biology is one of the world’s leading research institutes. The scientists are working to advance understanding of biological processes at the molecular level providing the knowledge needed to solve key problems in human health. The £200m project forms part of the newly-expanded Cambridge Biomedical Campus at Addenbrooke’s Hospital Cambridge.

The stainless steel cladding to four services towers have created a dramatic feature for the new building. Uginox Top, a low reflective stainless steel surface was specified by the project architect.

Approximately 14,000m² of interlocking shingles clad the towers which house all heavy plant servicing the building. The towers are linked to the main laboratory building rather than attached to it in order to remove weight and sources of vibration.

Durable surface

A 0.7mm thick Uginox Top was chosen for its flat matt surface aesthetic and high corrosion resistance.
Uginox Top has a fixed rolled on surface which requires only minimal maintenance.

The stainless steel advantages for this building:

  • A low thermal expansion coefficient
  • A high resistance to corrosion
  • A traditional work setting
  • A surface finish in harmony with contemporary architecture

Palace of Justice in Antwerp

The construction of the new Palace of Justice in Antwerp is the result of an international architectural competition.

The contract was awarded to the Richard Rogers Partnership team in association with Ove Arup and VK Studio offices who proposed an efficient, subtle and transparent building with a powerful symbolic image.

These “sail” roofs are the architectural focal point of the project. An extensive design study was necessary to determine the type of materials and construction methods required for these roofs. For example, wind tunnel studies were needed to determine the loads incurred during extreme weather. Each of the 32 roof modules is formed from four prefabricated quarters, that are then assembled on-site with a system of bolts. The geometric shape traced by these quarters is a hyperbolic paraboloid. This method simplifies the structural assembly and the fabrication of the components. Glued and laminated timber beams disposed on a frame in line with the straight lines of the sails and are mounted onto a tubular steel frame. Then three layers of planks are successively screwed on to form the shell.

The final roof covering is achieved with strips of 316L stainless-steel with Uginox Matt coating. Several technical constraints have pushed the designers towards this type of material: Natural durability, particularly when a site is exposed to maritime influences, the possibility of using welding techniques, complex geometry with either little or no angles in some places and extreme slants in others, lack of access for maintenance and of course; the visual aspect and colour.

To obtain a perfectly water-tight installation, the stainless-steel sheets are welded in a continuous seam using an automatic machine, thus creating an almost monolithic surface.

House Extension Bogindhu

Bogindhu is a large house extension and refurbishment of Bogindhu farmhouse in Aberdeenshire. The Project required a significant amount of work to the existing farmhouse including the removal of ground floor and first floor structures.

All internal walls of the original house were removed to reorganise the spaces within. The original external walls of the house were stripped back to expose the bare stone and re-lined to include insulation in order to increase the efficiency of the house.

The new house extension was designed as a contemporary barn structure, placed in an ‘L’ formation to complete the missing side of the farm court. The first floor was marked by a stainless steel band ( Uginox Top, type 316) which serves as a cill for the cladding and in places as a gutter. The roof is a 0.5 mm standing seam system set at 500 mm which was hand-formed on site and, at just 4kg / m², weighs considerably less than a similar system in copper, zinc or aluminium. Moreover, they prefered to replace the proposed zinc roof with a stainless steel one due to concerns that the run-off water from the larch cladding, which contains tannins, may have discoloured the zinc.  Uginox Top’s durable matt finish is designed to harmonise with a wide variety of building styles and materials, in this case vertical timber façades, full height windows and stone walls.

Internally, the house extension is deliberately different from the existing stone house, the spaces are large and open with high ceilings. The double height space overlooking the living room provides a sense of drama and contrast to the smaller, more intimate spaces of the cottage.

Stainless Steel – Courthouse, Strasbourg – France

Refurbishment of the Court of Strasbourg

After the French defeat in 1870 and the loss of Alsace-Lorraine to the German Empire, Strasbourg paid a heavy price. Unchanged since the 15th century, this historic town had to adapt. The adoption in 1878 of a development plan designed by a municipal architect Jean Geoffroy Conrath planned the expansion of the city to the north, beyond the fortifications of the 17th century. The desire from the new imperial power to found the Neustadt, or “New city”, responded to the need to establish its authority within an exemplary capital with official buildings and housing. Stretching beyond Ill Canal which later became the Canal du Faux-Remparts, the Neustadt was the place of some remarkable constructions such as the station (1883), the Palais de l’Université (1884) or the Palais Impérial (1888), creating a common eclectic construction style. The Neustadt was associated for far too long with a painful period in history but is today the symbol of an unwavering French-German reconciliation underpinned by a strong European culture.

The restructuring of the Strasbourg railway station in 2007 by the SNCF architecture agency Arep, which fits snuggly under a glass shell, triggered the town’s awareness which then embarked on a drive to protect the future of the buildings in the Neustadt. After the university library was restored in 2014 by the architect Nicolas Michelin, it was time for the Palais de Justice – built in 1898 by the architects Johan-Karl Ott and Skjold Neckelmann – to gain a new leash of life. This exceptional building of 14,920 m2 was part of a large-scale renovation project between 2014 and 2016 carried out by the Spanish Architect firm, Garcès-de Seta- Bonet.

Located within a densely populated area, the massive building has four grey sandstone facades displaying classic architectural elements (pediments, low relief carvings, columns…). Yet transforming an historical 19th century building into a 21st century court house requires the functional needs of modern public equipment to be supported whilst incorporating updates to comply with security standards applicable to establishments servicing the public (ERP rules). Well-designed from the outset, the internal functional organisation was preserved and adapted to current challenges, with people flow reviews depending on the changing trends in use and the creation of an extension. Designed to hold 225 magistrates and civil servants, this mammoth project involved three delicate construction sites which were located in the heart of the Alsace capital.

Uginox Patina – Weathering

Electrolytic tin plating

Uginox Patina K44 stainless steel sheeting features electro-tinned coating (100% pure tin) on both sides. This thin metallic coating does not provide corrosion resistance; the plating in fact serves two purposes:

  • Formation of a homogenous, matt grey finish (known as patina).
  • Gives a surface which promotes easy application of soft solder in complex details.

Patina formation

Over time, weathering causes the electroplated tin to form a uniform, matt grey finish (a patina) on the exposed surface of the rust free stainless steel base material. Patina formation takes a correspondingly longer time on unweathered surfaces. During the handling process handprints and mild staining can occur that may cause temporary blotchiness to the surface, these disappear as the patination of the surface develops into an even, matt grey surface finish. Uginox Patina K44 is supplied in an unweathered condition.

Applications of Uginox Patina – Uginox Patina K44

Uginox Patina K44 has proved itself to be an exemplary standard in aggressive environments. Accordingly, Uginox Patina K44 is more suitable for applications in aggressive industrial atmospheres and also in near coastal regions. Uginox Patina K44 is highly resistant to exposure to humic acids and is ideally suited to all kinds of rooftop vegetation. When attacked by particularly aggressive materials, in rare cases discoloration and streaking may form on the surface; however, these do not lead to corrosion of the stainless steel material. Should it be necessary to avoid such aesthetic issues, the use of Uginox Top is recommended as discoloration and streaking from the byproducts of chemical reactions do not typically form on its rolled matt surface. As with all materials individual material combinations may increase overall corrosion damage.
