Not for nothing has GRÖMO become the leading premium brand in Europe. A crucial part of the high product quality is meeting all the relevant standards. GRÖMO roof drainage components are manufactured according to EN 612. All specifications required under the standard, such as thickness or cutting of the material, are met in every respect. This is what the GRÖMO star stands for as a symbol of quality and the brand.
According to the standard specification of 1 July 2001, the drainage capacity of mounted and inset gutters, gutter drains, and downpipes must correspond to DIN EN 12056-3. You have absolute security during planning and calculating with the plug-in gutter outlets and diagonal outlets from GRÖMO.
The exact measurement data and related patterns for the right outlet opening are available under the “Tools and Service” heading for reliable, standardized installation. GRÖMO also offers a practical cutting template made of impact-resistant acrylic glass, which you can request from us using the contact form.
