Internal corner for gutter 33, cast anthracite RAL 7016

Internal corner, suitable for gutters with an unfolded width of 33 cm. The corners are part of K&J&G's roof drainage system.

The inner corner of the gutter is made of colored galvanized sheet metal in anthracite color RAL 7016. Colored galvanized sheet combines the excellent mechanical properties of galvanized steel with supply protection against corrosion, in the form of organic surface treatment. The surface treatment consists of applying polyurethane on both sides with a thickness of about 25-50 micrometers. Special varnish contributes to the greater hardness of the material.
