Nordic Galvanizers introduce Approved Galvanizer – a certification for galvanizing companies that galvanize structural steelwork that will be CE-marked by the steelwork contractor / fabricator
Approved Galvanizer means that the galvanizer has completed a certification that is developed for galvanizing companies, and among others has shown that it operates in accordance with the following standards:
EN ISO 1461
EN ISO 14713-2
EN 1090-2 (relevant parts)
Approved Galvanizer has been developed by Nordic Galvanizers, MVR (Mekaniska Verkstäders Riksförbund) and the certification body Nordcert, together with galvanizers and customer representatives. The purpose is to support galvanizers’ customers in the best way and make it easy and secure for manufacturers of steel structures to choose galvanizing for corrosion protection.
By selecting an Approved Galvanizer it is ensured that the quality and procedures during the hot-dip galvanizing is at the right level for structural components that will be CE-marked by the steelwork contractor / fabricator.
Supporting CE-Marking Obligations of Our Customers: The Role of the Galvanizer
CE marking simply demonstrates compliance with the appropriate manufacturing standard for a product. The harmonised standard covering fabricated structural steelwork in EN 1090-1 ’Execution of Steel Structures and Aluminium Structures’.
Hot Dip Galvanizing and EN 1090
EN 1090-1 and EN 1090-2 include specific requirements, related to surface treatment and durability that have consequences for the specification and use of hot dip galvanizing as a sub-contract activity.
However, a sub-contractor, without self providing products on the market under his name or trademark, can not be certified to EN 1090-1 by a notified body. (Ref. Boverket, Sweden). EGGA, European General Galvanizers Association, has published the guidance document “Hot dip galvanizing to EN ISO 1461 and CE marking of structural steelwork to EN 1090", which can be ordered from Nordic Galvanizers by mail: firstname.lastname@example.org

Norway's most environmentally friendly building?
Troll in Stavanger is the first building in what will be the new «Energy Quarter» at Hinna Park and is due for completion in October 2013. The building consists of two towers, one which stands five floors high and the other at eight floors. Both sections are connected by a middle section which extends over the lower three floors. Parking, bicycle neighboring building.
Troll-building will be one of the first office buildings in Norway that is built as both passive and Energy Class A. To qualify as passive requires support from government. Hinna Park wants to build passive approaching a zero energy building.
A coduktermpact building structure, excellent U-values, low infiltration facades, balanced ventilation with rotary heat exchanger, heat pumps based on carbon combined with energy buffer in the parking garage, and a solar collector on the roof, leading to an estimated total delivered energy of 59.8 kW / m². This corresponds to annual CO ² emissions of 22.5 kg / m².
Zinc is highlighted as sustainable by architecture students in collaboration with Stockholm City
“Into the loop - exploring the lifecycle of materials” is an exhibition made by students from Sustainable Studio at KTH School of Architecture. The exhibition is performed in a creative collaboration with Stockholm City and other stakeholders involved in the development of The Royal Seaport.
When finished, Stockholm Royal Seaport plans to hold 10.000 new apartments and 30.000 new work places. In addition to housing and offices, the area will also include urban parks, an art gallery and a harbor for cruise ships. As the City of Stockholm is the owner of the land, high demands are being put on the project to be on the front lines of sustainability. The project is part of Stockholm´s plans to densify the city as well as branding Stockholm as a leading city in green urban planning.
As for many other materials, the environmental properties of zinc sometimes is questioned, which the students were aware of. Thus, after some research and contact with researchers at KTH and other professionals with knowledge about the material, the students found out that zinc actually is a very appropriate material in terms of sustainability, when designed according to a cradle to cradle principle:
