Cold rolled stainless steel curtain wall

Cold rolled stainless steel plate because of the material’s own characteristics, its surface reflection is high, very sensitive to light, slight deformation will cause obvious visual experience; Its toughness is large, thermal expansion and cold contraction or other slight deformation and displacement will cause a greater impact on flatness; These characteristics determine that the flatness of the stainless steel curtain wall is higher than that of the ordinary metal curtain wall. Usual stainless steel curtain wall is the use of flange processing and V opening process, but the flange processing will produce a slight radian on the edge of the plate and affect the flatness, so for the cold rolled stainless steel plate curtain wall, as far as possible to choose the use of flat stainless steel for design and use; And the thickness of the stainless steel plate has an important impact on the flatness of the realization of different thickness which also determines the plate to use different processing and assembly technology and structural design.

The use of cold-rolled stainless steel plate in the glass curtain wall is generally used in the following ways: folding box type, flat type and composite plate type. Flanged box type refers to the plate with the four edges of the V-opening flange processing technology, and combined with the arrangement of reinforcing ribs for plate processing technology. Plate type refers to the use of laser cutting of stainless steel, with a fine cut plate directly used as the curtain wall panel, the plate because there is no folding process, so the plate can achieve extremely high requirements. Composite board type refers to stainless steel plate with backing plate or aluminum honeycomb panel using a special adhesive (entry “glue”) provided by industry encyclopedia way into plates, adhesive composition of the composite board type stainless steel plate flatness. It can meet the higher requirements, but the mechanical properties and high temperature resistance of adhesive has strict technical requirements.

Joint treatment: under normal circumstances, the use of cold-rolled stainless steel plate office curtain wall is recommended to use open seam joint treatment, the internal formation of isobaric drainage structure system. If the joints are used for gluing, it is necessary to remove oil stains on the surface of the stainless steel plate, and then apply a special epoxy primer. Otherwise, it is difficult to ensure the bonding and sealing performance of the sealant and the stainless steel plate.
