Step by step towards the fulfillment of our vision

“Craftsmen are the backbone of society. That is why we must pay particular attention to these industrious and hard-working people. The work involves great effort, but the methods and products are impractical and long outdated. I can still remember my blistered, scuffed hands after drilling exploratory holes in dry walls or the countless 25 kg plaster sacks that I lugged up to the 3rd floor. That must change!

I want to develop sustainable products and processes that facilitate daily work. Value creation must stay in the craft sector to secure their existence. Electricians and electrical engineers should concentrate enthusiastically on their task. I have a vision to revolutionise the trade and I have been working on this with an incredible team for over 15 years.”

Our History

2022Super cool & super practicalWOW! This is not just how our customers react when they use the new concrete installation housings. We were also amazed when we received great news in the spring of 2022. The XL-Series actually won the Red Dot Award! The award at one of the largest design competitions in the world is internationally regarded as an absolute seal of quality. The great thing is that it's not just about the looks. In addition to the design, the judges focused on innovation, quality and functionality of the products. The Red Dot jury was not alone with this opinion. The XL series won further awards at the Focus Open, the official design competition of the state of Baden-Württemberg, and at the design competition at Light and Building, the world's largest electrical trade fair. So now we have it official: Our built-in housings look great and really pack a punch!

2020Hey, everything shines, so nice and newWernher von Braun was the pioneer of modern space travel. We see ourselves as pioneers of modern electrical installation. How appropriate, because the Primo headquarter has been at Wernher-von-Braun Str. 2 in the tranquil Aschau am Inn since July 2020. Why are we so excited? Since 2020 there has been a showroom with an elegant glass front, the warehouse on 1,200 square meters, height-adjustable tables, a freely usable health center with fitness equipment, sauna and pool, the XL team player room for cooking, enjoying and relaxing and so on and so on. We also released the updated version of two products in 2020: the Primo Thermo Box and the Primo Membrane Box with hinged wings. We always have something going on.

2019We dedicate ourselves to concrete factoriesA modern concrete factory no longer sets components by hand, but uses the Primo concept “concrete factory of the future” for higher added value, series production and minimization of the number of complaints. The secret is the combination of pallet magazine, laser and magnetic technology. No more inaccuracies or adhesive residue!

2017 – 2018 Make a big difference with little helpers!How do you remove the drill core from the hole saw? And how do you fix a concrete box on the back wall of the formwork? Since 2017, our answer has been: with the practical helpers from Primo! The Bohr-Fixx with holder for all hole saws from 35 mm is a hole saw adapter with a special ejection function for the drill core - in a matter of seconds! With the 40 cm long “Primo Nailer” covers or boxes can be nailed to the formwork even after the steel reinforcement has been installed.

2016Are you still plastering
or are you already foaming?Derided by the industry, viewed with skepticism by customers – in 2016, Primo caused a stir in the electrical industry! Suddenly flush-mounted boxes should not be plastered, but rather foamed. Doesn't work at all? We say: yes, and success proves us right! Instead of hauling heavy plaster bags, water buckets and mixers to the construction site, a foam can of Primo Thermal Foam is used for the flush-mounted installation and furthermore, is absolutely thermal bridge-free and airtight! What's it like? Are you still plastering or are you already foaming?

2013 No idea about sales, but a heart for electrical installationWithout further ado, loading the Sprinter with the self-made exhibition stand and three individual products in the suitcase, Thomas and Herbert set off for the eltec in Nuremberg, the first trade fair as exhibitors. It starts without sales practice, without trained salespeople and without an order block. They quickly realize that using time-saving products is much easier than selling the products. But the audience is enthusiastic and the exhibition stand is full to the last square centimeter. “We did it,” they both think, without realizing that less than seven years later Primo sales will increase by 800%.

2012 – 2013Let there be light!So that Primo customers are no longer left in the dark, Herbert Wintersteiger is developing new installation housings in different sizes. Especially in concrete construction, the housings are unbeatable due to the flexibility in the concreting process and the type of fastening as well as the quick but very precise assembly.

2010When it needs something moreIn 2010, we created with the drilling template a practical helper for quickly milling out several box recesses. The first hole is marked and milled out, then the box can be perfectly aligned and the drilling template can be moved as often as desired using the integrated spirit level and the lever for fixation.

2007 Awards for innovative productsCountless sleepless nights in the company are finally paying off two years later. Primo GmbH receives the “Federal Prize for Outstanding Innovative Achievements for the Trade” for the Winged Concrete Box and the “Bavarian State Prize” for the Multi Box. For the first time in 16 years, a company will receive both prizes in a double pack.

2005We want Primo for everyone!The Wintersteigers notice that their own creations save time, money and nerves. They definitely want to share this innovation and work simplification with the entire industry! On May 9, 2005, things got serious: Primo GmbH was founded. Fun fact: Primo was not only chosen as the company name because it stands for “the first”. First-class discos on Lake Garda may also have something to do with it.

2002 The round must go into the square!When installing a Munich museum with an exposed concrete look, it becomes clear once again how impractical the common installation products and methods are. Small round boxes should be fastened into the steel mesh with large square openings. How does it works? Herbert and his team find pieces of metal on the construction site to attach the box where it needs to go. This has to be different! However, the final implementation of the Wing Concrete Box was still five years away.

2000Multi BoxSearch for the previously placed boxes with the hammer? This pleases neither painters nor customers. Herbert begins developing a box that can be installed flush with the plaster. The system for locking the cover allows the electrician to individually adapt it to the unevenness in the wall.

1998Necessity is the mother of inventionA large construction site with 250 apartments cost the installation company a lot of money in 1995! What happened? Due to the drywall work, search holes are necessary to find the previously laid cables. This should never happen again! This is how our creative inventor Herbert developed the plunger, now known as the Cable Carrier. The product with a length of 13 cm is glued to the first panel, the cables are fixed and the drywall is marked with it. The walls no longer become Swiss cheese, sound and heat insulation are completely preserved! Herbert didn't know it yet, but that was the birth of the Primo motto: "From professionals for professionals!" By the way, our Primo boss Thomas started his training as an electrical installer this year, his head then (as now!) full of ideas.

1985 The journey starts…Herbert Wintersteiger dares to become self-employed and founds his electrical installation company “Elektro Wintersteiger” in the tranquil town of Pürten (Upper Bavaria). Did Herbert already have an idea back then where the journey would lead?
