Standing Seam Roof Aluminium Zinc
Aluminium-zinc coated sheet steel that can be used until corrosivity class C4. The metal coating consists of 55% weight percent aluminium, 43,4% zinc and 1,6% Silica. The coating weight is 185 g/m2 and double side, and is named AZ185. The layer of Aluminium-zinc is 25 μm (0,025 mm) thick per side. The surface is treated with anti-fingerprint to prevent discolouring during handling and to facilitate shaping. The steel core in the tinsmith quality is an extra soft sheet steel. The material has practically no spring back, making it possible to make tight seams. The material can be both machine and hand seamed.
For both the sake of corrosion and appearance, avoid the following combinations:
• Aluminium-zinc in combination with copper, brass, iron and led as that can give rise to galvanic corrosion.
Avoid runoff from these substances and bitumen products onto the sheet steel.
• Wet concrete, cement and plaster which are strongly basic.
• Aluminium-zinc in contact with hardwood, wet tree or pressure treated wood containing copper.
