A variety of steel components at Stahlbau Hausmann.

Key Facts at a Glance

The Customer

Hausmann GmbH & Co. Stahlbau KG is a family-owned structural steel fabricator that has been delivering complex steel and metal structures since 1946. The company handles every stage, from project planning and engineering to fabrication and installation. Its capabilities include industrial facilities, large-span buildings, facades, bridges, stairways, and custom structures, with a focus on quality and reliability.

The Challenge

In structural steel fabrication, thermally cut components often vary widely in shape and size. Achieving preparation grade P3 under DIN EN ISO 8501-3 requires removing slag and burrs, grinding the cut edge faces, and rounding all edges to a uniform 2 mm radius (R2). Performing these tasks manually is time-consuming and physically demanding. The ongoing skilled labor shortage also makes it difficult to recruit and retain qualified employees for this work. Stahlbau Hausmann needed a flexible solution that would deliver high-quality results while reducing manual labor.

The Solution

• Fully automated deburring and finishing of flame-cut and plasma-cut parts to preparation grade P3 under DIN EN ISO 8501-3.
• Automatic slag and burr removal, grinding of cut edge faces, and rounding of all external edges to R2.
• Task-specific tools, including chisels, flap discs, rotary burrs, angle grinders, and countersinking tools.
• Part geometry recognition using 3D vision technology—no programming or CAD data required.
• Processing of one-off parts and small production runs with frequently changing geometries.
• Fully automated gripping, positioning, and flipping of parts for processing on both sides.
• Installation in a dust and noise control enclosure for safe, clean operation.
• 24/7 operation for maximum equipment utilization and consistent production output.
• Sustainable solar power to run the system.

The Results

• Repeatable results up to preparation grade P3 in accordance with the standard.
• Fewer workers needed for manual deburring and finishing.
• Significant time savings through automated workflows.
• Processing of varied part geometries and one-off parts without programming.
• Reduced physical strain on employees.

Why Teqram

Stahlbau Hausmann chose Teqram because the EasyGrinder combines 3D vision technology with autonomous control to automate processing without programming and handle all finishing tasks in a single, integrated process. Its flexibility in handling different parts and processing tasks makes Teqram an ideal partner for demanding structural steel fabrication.

Conclusion

With the EasyGrinder, Stahlbau Hausmann is modernizing the preparation of thermally cut parts to preparation grade P3, improving efficiency and repeatability while reducing physical strain on employees. The solution strengthens the company’s competitiveness and positions it for the future as skilled labor remains in short supply.
