Special Mention at German Brand Award 2018


On June 21, 2018, the prize for successful brand management was awarded in Berlin. In the Industry Excellence category in Branding / Building & Elements, MLL-HAMBURG has been awarded the Special Mention Prize. This award honors work for special aspects of brand management - a distinction that honors the commitment to the competitiveness of German brands.



MLL-HAMBURG produces with Elan for its customers: MLL at work! And MLL is also building small works of art for you or already producing a very own lighthouse, if you wish - for MLL is creative: MLL art work! MLL is authentic, is Hamburg manufacturer, produces quality and can always be something for its customers.

Together, we are what each one of us is individually.


Also in that year, the company presented itself as an exhibitor at the Munich trade fair, BAU 2015. The highlights of the MLL trade fair were products for weather protection and sun protection, which were demonstrated in a visual and tangible way. Almost the entire stand was made from MLL products. All the individual parts added up to the entire stand, and each one of us helped to turn it into a sum total. The campaign motto "I AM MLL - WE ARE MLL" was thus presented in a visible and tangible way. 

Celebrating MLL-HAMBURG’s 30-year anniversary


The 30th anniversary of the company is not only a reason to celebrate, but has also been used to inaugurate the completion of the expansion into our new production hall. The production facility now has a total area of approx. 2100 m²2. 30 years of MLL – this represents 30 years of growth in experience and expertise in the areas of weather protection, sun protection and ventilation.

Weather protection and sun protection can be combined


As a competent manufacturer of weather protection grids, slat systems and ventilation systems made of aluminium, after successfully taking over the sun protection systems of the sonal brand, we have developed a combined product range consisting of weather protection and sun protection systems.

MLL-HAMBURG has a new family member!


Sun protection products were previously a part of the sales portfolio, but they were not manufactured in-house, rather they originated from manufacturers such as the former company c. behrens sonal GmbH, Hannover. This already existing business relationship as now led to the takeover of the sonal brand, so that MLL now also produces sun protection made of aluminium in its own facility.
