The family-run company was set up in 1949 as an individual business, then converted to a limited liability company (GmbH) in 1989, and expanded to a limited commercial partnership formed with the GmbH as general partner (GmbH & Co. KG) including further branches of business in 2005.The Porath Group is still family-owned and is managed by Hans-Jürgen Porath and his daughter Nadine Ruelfs.At the beginning of the 1970s we were operative in the automotive sector too in addition to the steel construction branch, and were also suppliers of soil working implements – welded structures used to build agricultural machinery.

This led to the segment of plant installations and mechanical engineering, in which we serviced projects of Thyssen Industrietechnik and Schwelm Anlagenbau. For example water treatment facilities and ship loading installations were designed in which pneumatic and hydraulic controls were used too.

In 1993 we acquired a holding in POMA GmbH, who manufacture conveyor equipment for hot and bulk goods, and in Optus GmbH, who manufacture loading systems for water craft as well as rail-bound and road vehicles. This developed into a market for fabricating special products and systems that both companies handle via Stahlbau Porath GmbH & Co. KG.Our qualified staff and our production skills and techniques are the prerequisite for covering the field of lifting and conveyor equipment and engineering, from planning, through production, right up to service.We founded the company Hebetechnik Porath GmbH & Co. KG to handle this branch of business.

At present our company employs a workforce of about 35.Our production capacity for medium-heavy steel structures is currently approx. 100 t/month.We have some of the assembly and erection work carried out by specialist subcontractors with whom we have been collaborating for many years now.Our commercial department is equipped with modern computer equipment and our engineering department is able to carry out all the necessary stress analyses and prepare all design drawings with CAD in 2D and 3D.As a welding firm we hold the comprehensive qualification certificate for welding steel structures issued by the welding institution SLV Duisburg in accordance with DIN 18800-7.Our company is certified to SCC* by DEKRA.
