Roll bonding is a beautiful technology for bonding dissimilar metals. Two metals sheets are heated up and pressed with high pressure into a vacuum resulting in the mechanical bonding of the two plates. 

The out come is a metal composite plate which combines the strength of the steel and the chemical resistance of other alloys.

For the new Slussen Bridge in Stockholm we designed a new assembly using aluminium bronze. It is able to withstand  the highly corrosive  environment of stockholm and has a beautiful metallic gold aspect.
