Thin Joint Installations of Stainless-Steel Panels

At Kikukawa, we provide outsized architectural panels with thin joints. Typically, joint details are designed at roughly 15mm, however, Kikukawa is able to answer requirements of up to 5mm thin joint details. As an example of this, we provide the following pictures of the stainless-steel wall panels of Kikukawa Group Tokyo Office.

Twenty-seven Silky blasted* exterior wall panels cover roughly 120㎡ of staircase walls from the 1st to 3rd floor.

There are other examples of Kikukawa’s stainless-steel panels installed with thin joints. At Aga Khan Centre of London (UK), 3.0mm thick stainless steel is installed with 5mm thin joints to create an octagonal column. Within Japan, the balustrade walls of the Japanese Sword Museum are installed with the same details of 3.0mm thick stainless steel with 5mm thin joints. (Kikukawa’s stainless steel panels are also utilized in the main and sub-main entrance area with 4.0mm thick stainless steel with 6mm thin joints details.)
