01 product description
TECU® Brass is a new material - with a reddish golden surface for impressive new façade solutions using copper.
TECU® Brass is a CuZn15-grade copper and zinc alloy that has been specially designed for use on façades. Weathering changes the original reddish golden colour of the surface in a very lively manner, with each façade developing its own unique characteristics. After the initial matting, the surface takes on a greenish brown tone, which slowly turns greyish brown before evolving into a dark brown-anthracite colour. On sloping surfaces, a uniquely individual patina layer typical of classical copper surfaces develops.
TECU® Brass offers outstanding mechanical abrasion resistance, extremely high corrosion resistance and durability as well as excellent stability and material rigidity. The material can be easily cold-shaped and soft-soldered. Because of its special material characteristics, TECU® Brass is also well suited for large-area applications.
TECU® Brass is an ideal complement to the TECU® product range and can be perfectly combined with the other copper surfaces. TECU® Brass offers without exception all the familiar economic advantages of the TECU® brand name.

02 Technical Data
Façade and roof elements from TECU® copper for angle standing seam, double standing seam and batten cap cladding are produced from sheets or strips. In façades vertical or horizontal cladding is usual which lends the façade a visually appealing structure.
Roof cladding is generally carried out using the double standing seam technique. The water carrying layer of the roof covering is outside the seam ends. Up to a minimum roof pitch of 3° (5%) the seam is described as watertight. However, the double standing seam is not waterproof against such things as banked-up water.
The traditional construction in the plumbing trade is the ventilated facade as well as ventilated and non-ventilated roof cladding using angle standing seam, double standing seam and batten cap techniques. In addition to DIN 18351 and DIN 18561 ventilated façade constructions are also based on the professional standards of the trade.
