The history of Minka began in the 1950s, when the young Franz Janner built his first attic staircase. Initially only intended for his own use, this soon developed into a business idea. Franz Janner worked constantly on improving his product and so his father Ernst Janner Sr. was finally able to register a patent for various functions of the attic staircase on 2 November 1951. Based on this, father and son officially founded a company in 1952 – inspiration for the company name “Minka” was provided by the family’s cat, who also enjoyed the attic staircase at home.

In the years following the founding of the company, production and sales were exclusively in the hands of the Janner family. Ernst Janner senior took over the management, but his wife Rosa Janner and their son Franz Janner also put all their heart and soul into the manual production of their loft ladders. As a result, the products quickly found favour with the house builders in Austria. Soon the facilities in Vorarlberg were too small for the company and the Janner family had to move the business to another location. The choice fell on a centrally located place in Styria and in 1956 Minka finally opened its doors in St. Lorenzen im Mürztal.

From their new home in the heart of Austria, the Janner family was able to realise the potential of their business idea even better. The factory was steadily expanded and more and more employees supported the company in production and sales. But not only the team grew, but also the sales figures. The Austrian market became increasingly saturated, which is why the first export activities to Switzerland were started. The 60s also saw the first change of managing director in Minka’s history. In 1966, Ernst Janner senior handed over responsibility for the company to his son Franz Janner.

Since the founding of the company, Minka has filed a number of innovations with the patent office and as a result has been granted the associated claims. In 1972, Minka was once again the pioneer of a new generation of stairs: the fire-retardant metal staircase. In the course of developing this innovative product, the Janner family founded its own powder coating department. With this method, Minka was able to surface-finish the metal parts for the stairs itself. But it did not stop at coating their own materials, because soon external customers also became aware of this new technology from Minka. This is how Minka Powder Coating developed into its own business division, which is still very successful today.

In 1986 Franz Janner handed over the company to his son Ernst Janner jun. who had big plans for Minka’s product range: In addition to attic staircases, Minka would henceforth also produce system staircases. In the late 90s, the production of the new spiral staircases, space-saving staircases and galvanised staircases for outdoor use increasingly gained momentum. But it was not only the product range that grew strongly after Ernst Janner Jr. took over, but also the distribution network. Minka established more and more relationships with international partners and was thus able to open up more and more markets in Central Europe.

The production and office areas have been continuously expanded and converted since the company was founded. Between 2000 and 2015, there were again major changes to the premises. The St. Lorenzen site was completely renovated and a showroom was added, where customers and business partners have since been able to admire our products live. In addition, Minka opened a second location in Kindberg in 2010 to further expand the production of system staircases. This caused the export rate to skyrocket once again. Now sales were no longer limited to the European market, but more and more countries from other continents became aware of the quality and durability of Minka stairs.

Since 2025, Mareiner – a specialist in wood finishing – has been part of the Minka Group. Its headquarters, located in close proximity to the Minka headquarters, strengthens regional roots and enables particularly close collaboration. Through this integration, the product portfolio has been strategically expanded and enriched with in-depth expertise in high-quality finished wood products. This creates new synergies as well as additional potential for product innovations along the entire value chain.

At the same time, the Minka brand world has been consistently further developed. With the introduction of Minka Wood for premium wall panels and terraces, as well as Minka Garden for fences, railings, and outdoor solutions, a clear and structured brand system has been established. The rebranding of the powder coating division to Minka Coating further highlights the high level of in-house manufacturing depth and technological expertise. As a result, the Minka Group positions itself as a strong umbrella brand that unites several specialized brands—connected by quality, innovative strength, and a clear focus on modular, sustainable solutions.
