Copper strips, sheets and laminates for building and industrial applications.
Silmet, a traditional copper tube manufacturer, has started manufacturing copper strip, sheet and laminate for building and industrial applications.
In line with its long tradition, Silmet has always invested in the very best and most advanced technologies available for this kind of product using state-of-the-art equipment.
Characteristics
Copper is used to produce the whole Silmet product range. Copper has many advantages over other materials including excellent electrical and thermal conductivity, unparalleled mechanical and physical properties, not to mention the fact that it is 100% recyclable.
The production and finishing lines, which are largely automated, guarantee the top quality standards of the products present on the market.
Silmet’s copper strips, sheets and laminates are ideal for use in the construction industry, in particular for roofing and cladding. The copper strip can be used to make gutters, downpipes, cladding and roofing systems. In the industrial field Silmet copper strip meets the strictest quality standards set out in EN 1172, especially in regard to annealing, dimensional tolerance and coil weights.
Due to copper’s excellent corrosion resistance, all strip supplied does not require any coating, such as painting or varnish, or special maintenance, and is highly resistant to corrosion, not to mention the purely cosmetic aspect which copper confers to the products it is made with.
Directives
The international standards to which Silmet strips conform are:
EN 1172
Sheet and strip for building purposes
EN 1652
Plate, sheet, strip and circles for general purposes
According to Specification
Products with marks, dimensional tolerances, physical states and other characteristics defined on specific request by the Customer, even in partial modification of the specifications indicated above.
