For three generations, the founding family Ritter and their descendants have been moving the market around steel production and concrete reinforcement. What started small with the founding of AVI is now a successfully operating group of companies under the umbrella of the family-run M + S Maschinen und Stahl Holding GmbH. The globally active group, which covers the entire range of reinforcing steel and welded meshes, also includes:
As a result of significant technical developments, the group of companies is now a globally active association of specialised companies and full-service providers.
Thanks to the joint location of AVI, EVG, H+S and BSTG in Raaba-Grambach near Graz, the experience gained can flow continuously and directly into the development of EVG machines and facilities, for example.
With its products and services, AVI is an integral part of the group, with the product range extending from classic to technically complex products. In addition, the implementation of individual customer-specific solutions as well as technical consulting on the topic of “concrete reinforcement” are central fields of activity of the company.
M+S Maschinen + Stahl Holding GmbH
In 2016, M + S Maschinen und Stahl Holding GmbH (Machinery and Steel) was founded, whose wholly owned subsidiaries are AVI, EVG, Marienhütte and Stahl-Form.
EVG
EVG has been building machines and facilities for the production of welded mesh and the processing of reinforcing steel since 1949.
EVG is a globally active mechanical engineering company specialising in the development, construction, and support of machines and factories for processing wire and reinforcing steel. EVG is THE worldwide partner for welded mesh and off-coil processing of reinforcing steel.
As a mechanical engineering specialist for mesh welding facilities, rolling mills and automatic straightening machines for reinforcing steel, EVG develops and supplies production facilities worldwide with maximum production output and highest reliability.
In addition to engineering and assembly, EVG offers its customers, among other things, the conception of logistics and material flow and the design of peripheral equipment. The services extend to complete factory planning.
The extensive aftersales service offers comprehensive support during installation and commissioning of the systems, as well as support throughout the entire operating period. Training for the technical staff of EVG customers and the supply of spare parts are a matter of course.
The company’s success is based on the know-how and competence of more than 500 committed employees. A significant competitive advantage lies in the cooperation with the sister companies AVI, BSTG, Marienhütte, Stahlform, and H+S Zauntechnik, which provide support in the development of new products and in test phases.
Did you know? We at AVI also mostly use EVG machines for the production of our reinforcement products.
Marienhütte
The steel and rolling mill Marienhütte, based in Graz, is Austria’s only producer of reinforcing steel and one of the most efficient reinforcing steel plants worldwide. In addition to high-tech production, maximum energy efficiency, and closed material cycles, this mainly means resource efficiency: all materials used in our plant are treated in such a way that they leave the plant as a product or can be used again sensibly in the economic cycle without having to be burned or landfilled.
For the production of reinforcing steel in bars and rings, Marienhütte uses only scrap instead of primary raw materials. At the end of its service life, the reinforcing steel becomes scrap again, from which reinforcing steel can then be produced again. The heat generated during the production of reinforcing steel has been fed into the district heating network of Energie Graz for 30 years. This supplies 50,000 people in Graz with 100% CO2-free heat. In addition, all material flows are optimised and any input materials are sensibly recycled in order to avoid landfilling or burning. Reinforcing steel from the Marienhütte is thus an active contribution to climate protection.
Did you know? We at AVI also use some of the reinforcing steel produced by Marienhütte to produce our concrete reinforcement products.
Stahl-Form Baustahlbearbeitung GmbH
Since 1989, Stahl-Form has been a reliable partner of the Austrian construction industry when it comes to the processing of reinforcing steel. Especially in the provinces of Salzburg, Upper Austria and Tyrol, Stahl-Form makes a significant contribution to the implementation and execution of building construction and civil engineering projects. Through individual project planning, high flexibility, and an extensive delivery program, Stahl-Form can quickly respond to special requirements and special requests. In addition, specialised staff and modern machinery guarantee a high level of production quality and efficient processing of orders.
Furthermore, Stahl-Form offers its customers professional installation of reinforcing steel on the construction site by qualified personnel. In doing so, they work closely with experienced companies that specialise exclusively in installation of reinforcing steel.
Did you know? In addition to its own portfolio, Stahl-Form also offers AVI products. In 1994, AVI acquired a stake in the company, and in 2014, Stahl-Form was fully taken over by the company group.
BSTG Drahtwaren Produktions- und Handels-GmbH
BSTG specialises in standard and customised electro-welded wire meshes. Standard and custom meshes for concrete reinforcement are manufactured at the two production facilities in Linz and Raaba-Grambach near Graz. In addition to the standard mesh range, the ÖMAT wire mesh with loops, developed by AVI especially for the Austrian market, are also produced.
BSTG Drahtwaren Produktions- und Handels-GmbH is a joint venture between M + S Maschinen und Stahl Holding GmbH and the Italian Gruppo Pittini.
Did you know? BSTG Linz was taken over by AVI in 2002. In 2013, M + S Maschinen und Stahl Holding GmbH participated in the sale and outsourcing of the construction steel mesh production at the Raaba site and took a strategic stake in BSTG as part of a joint venture. This ultimately also meant AVI’s exit from the reinforcing mesh business.
H+S Zauntechnik GmbH
H+S ZAUNTECHNIK GMBH IS YOUR CONTACT FOR FENCING AND FOR DOOR AND GATE SYSTEMS.
As a specialist in planning, production, sales and installation, H+S Zauntechnik GmbH offers a comprehensive and tailor-made portfolio for fences, doors and gates in and around Austria.
The product range extends from chain link fences and wire mesh fences to self-developed column systems and high-quality complete solutions made of aluminium and steel.
From a total of 4 locations, H+S is the contact for customers from the private, commercial and industrial sectors.
Not only the production of fences but also individual customer counselling is a central part of the scope of services.
The focus is clearly on the customer: communication, joint planning and individual solution finding are the cornerstones for a sustainable customer relationship, in addition to the highest product quality.
Did you know? H+S emerged from AVI: In 1993, AVI spun off its very successful “Fences, Grids, Gates” business segment and founded H+S Zauntechnik GmbH as an independent company.
