functional details for easy assembly
More than 130 years of experience in metal working, pioneering spirit, and knowledge about the growing challenges of working with roofs are what make up consistently trendsetting innovations at GRÖMO.

Our products are continually developed further in constant dialogue with customers, and streamlined in quality, functionality, and application.
SAFE, STANDARDISED COMPONENTS
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.
QUALITY STARTS WITH THE FINEST RAW MATERIALS
Premium materials are the first prerequisite for high quality and excellent accuracy of fit. At GRÖMO, only high-quality raw materials from European suppliers are used.
With agreements for liability assumption and material guarantee, GRÖMO offers even more security. The agreements were made with the two big industry associations, ZVSHK and ZVDH. They apply for all independent craftspeople and craft companies entered in the Register of Craft Businesses who are members of one of the associations related to ZVDH or ZVSHK, and cover damage that occurs due to errors in construction, manufacturing, material, or because of flawed instructions (e.g., incorrect assembly instructions). For client claims, GRÖMO assumes the respective obligations. The rights and responsibilities of the contracting partners are regulated in detail in the agreements. The prerequisites for a guarantee claim and contents can be found in the contracts.
In order that our customers always have the security and retain the quality that we promise, we do not allow any compromises when selecting suppliers, nor during testing and checking our products.
Strict monitoring, full documentation of all work processes, continual improvement, and regular employee trainings form the foundation for GRÖMO’s quality standards.
Because it's only through consistent high quality that we can satisfy our customers on a long-lasting basis: They’re the ones who decide if our products are meeting the expectations set in place.
