In most of the world, sheet metal thickness is consistently specified in millimeters. In the U.S., the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its gauge. The larger the gauge number, the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge.
Architectural bronzes usually contain about 90% copper and 10% tin, although the content may vary widely. The term “tin ceiling” is a misnomer and early manufacturers did not use the name.

Copper is a good choice for gutters and downspouts because it makes strong leak-proof joints. Gutters and downspouts made with copper are expected to outlast other metal materials and plastics. Even in corrosion-prone seacoast environments or in areas with acid rain or smog, copper gutters and downspouts can provide 50 years or more of service ...
Metal roofs are 100% recyclable and can be made from other recycled products. Asphalt shingles are petroleum based with other chemicals making their recycling process more toxic, most shingles are not recycled and 20 billion pounds (9.1 million tonnes) are sent to landfills every year and take hundreds of years to decompose.
Finlock gutters, a proprietary name [31] for concrete gutters, can be employed on a large range of buildings. There were used on domestic properties in the 1950s and 1960s, as a replacement for cast iron gutters when there was a shortage of steel and surplus of concrete.
