Fields of application
- Automotive and commercial vehicle industry: In every European car are components made of SAH steel bars, from gears, piston rods and tempered and ground steering gear shafts to suspension components such as stabilizers, torsion bars and coil springs.
- Chain producing industry: High quality round steel chains, hooks and shackles were made from SAH steel bars
- Tool industry: SAH steel bars are highly appreciated in the manufacture of drills, chisels and socket wrenches.
- Wind power projects: As gear shafts or as quenched tempered threaded bolts SAH steel bars serve in wind power plants.
- Oil industry: From case hardening steels and steels for quenching and tempering sucker rods will be produced.
- Agricultural technology: our round steel bars are used to fabricate highly stressed tools for tillage. Even ball and roller bearing steels as well as free-cutting steels were used in motor and gearbox components.

SAS thread bar systems
Solutions for individual challenges in technical engineering.
Our SAS systems feature high quality thread bars of various grades, up to prestressing steel quality, in a range of diameters from 12 to 75 mm. We provide various system solutions for a variety of technical engineering purposes, including thread bar anchors for mining and tunnelling, reinforcement connections, form ties, tie rods, soil nails, micropiles, rock and soil anchors for geotechnical applications as well as prestressing tendons for post-tensioning.
Our SAS thread bar systems are used for connections, formwork and anchorages and have been installed in large-scale construction projects worldwide. Whether for building, underground, bridge or road construction, tunnelling or mining, we can supply the steel you need to get the job done. In the technical engineering sector, our SAS system products have made us the leading global supplier of hot-rolled thread bars.
Providing individualized solutions for specific customer requirements is a challenge we gladly accept.

Steel production
This is how our steel is made.
The centrepiece of our production is a 22-stand continuous small-section rolling mill in which materials of diverse grades, pre-heated up to approximately 1,200 °C in the walking beam furnace, are rolled out to diameters between 12 mm and 75 mm. Part of the material is already tempered in the rolling mill utilizing the rolling heat. After cooling and cutting, the material goes to one of our 9 finishing lines for further processing.
In the steel bar finishing lines, our SAH steel bars with diameters ranging from 12 to 40 mm are annealed, straightened, sawed, shot-blasted, chamfered and checked for surface defects. Part of the bar material is further refined by using peeling, straightening/polishing and grinding, followed by another surface check and/or ultrasonic testing. Additional production stages comprise sawing including end forming, turning, grinding, deburring and gear cutting.
Our SAS thread bars with screwable continuous coarse threads ranging from 12 mm to 75 mm in diameter are either delivered pre-assembled or undergo additional treatment processes, such as stretching followed by annealing in order to produce special grades with specific strength values. The screwability of the thread bars is checked continuously.
Part of the material is subjected to further in-house processing such as bending, locking and other assembly steps, which enable us to offer our customers complete system solutions.
The required accessories are also produced in-house using various gang drilling machines, whirling machines and CNC lathes.
