Foundation of the workshop

Herman Rauter decides to make electrical installations his core business. He found out how poorly installed and maintained lightning protection systems were through a number of electrical measurements.

New materials for imperceptible lightning protection

Continuous growth of the operations, which made it possible to meet the market demand, as well as the development and introduction of higher quality non-corrodible materials as a new, exciting trend in lightning protection. HERMI is on the fast track to establishing itself as a manufacturer of lightning protection components that are imperceptible on roofs and facades.

Expansion of the lightning protection range of products and a new location

The company expands its range of lightning protection products and also offers design and professional consulting to increasingly demanding customers. Production capacities become too small so the entire company moves from Velenje to Celje.

Investments in production facilities and design development

The company expands the existing facility to be able to upgrade its production facilities. The management connects with specialists and software developers to upgrade its design services. The new software tool SHIELD comes to life, allowing customers to plan lightning and surge protection faster and better.

Transformation, new management and entry into foreign markets

The company is transformed into a limited liability company. That same year, the long-time director and owner Herman Rauter leaves the management of the company to his son Miran Rauter, who had spent many years learning from his father and had got to thoroughly know the markets, operations and company’s business. The company also seized opportunities in expanding to foreign markets by opening its business unit in Croatia and a year later in Bosnia and Herzegovina.

Growth of sales, entry into the Serbian market

Due to a significant upward trend of new orders and an increase in demand the company invests in a new business facility, making it easier to advise customers and utilise additional storage capacity. The company also establishes a new business unit in Serbia.

Hermi® surge protection and new markets

The launch of the Hermi® surge protection product range marks a new milestone in the company's development. Customers can pick from all the highest quality external and internal lightning protection elements in one place. That same year, the operations are expanded with an active breakthrough into new markets: Kosovo, Romania, Bulgaria, Macedonia and Russia.

Production modernisation and international certificates

The company modernises and automates the entire production and plants as much as possible, and invests in the development of new products in accordance with national, European and international standards. All the company's products successfully pass many tests to obtain the strictest certificates.

New business and production facilities in Slovenia and in Croatia

The company can meet its production plans in the face of the growing demands of individual markets due to the construction of two completely new business and production facilities in Celje and near Zagreb.

Entering the Austrian and Hungarian markets, projects in the Middle East

In addition to establishing a subsidiary in Romania, the company also enters the Austrian and Hungarian markets. Successfully implemented projects in Saudi Arabia as an example of good practice create new opportunities for selling products and services in other Middle Eastern countries as well.

Recipient of a reputable award

Even after 30 years, the operations are growing with the speed of light thanks to the growth of sales in foreign markets as well as to innovation, technical support and environmentally friendly products. The Chamber of Commerce and Industry of Slovenia therefore present the director Miran Rauter an award for outstanding economic and entrepreneurial achievements for 2015.

New production technologies in Slovenia

The company builds a new facility in Celje due to the growing production and numerous technological improvements of production lines.

Upward trend in other European markets

A subsidiary is established in Austria on the foundations of the company’s innovativeness and success in other European markets, especially when it comes to planning and design. It allows HERMI to cover the German and Swiss markets better and more easily.

High-tech upgrade of the production automation

The production automation process continues with investments in new, technologically advanced production lines at the new location in Celje.


We are focussed on the continuous development of each of our four programmes to offer comprehensive solutions under one roof. We eagerly look towards the future with optimism – we carefully enter new markets to never lose sight of what we strive for: to go the extra mile, beyond the expectations of our customers, while maintaining the high satisfaction of existing and new customers.

Standout references

We consistently strive to meet or exceed our comprehensive quality standards. We keep looking for new ideas and approaches to develop innovative solutions because our partners deserve only the best.
