Laser based contour measurement for bars and rebar

Measure and determine dimensions, rolling and surface defects, as well as straightness of rods utilizing optical laser systems from LAP.

Our laser measurement systems improve the product quality of hot and cold rolled bar and rebar profiles and secure a stable production. In addition, you can check with LAP the straightness of long steel products.

Essential quality assurance

Your benefits

Cost reduction

Our systems communicate tolerance violations in real time. You'll save considerable costs by being warned before producing scrap.

Optimized operating periods

After changing the product, the scaffolding will be retracted to the new products faster than before. You can then quickly get back to producing within tolerance.

Permanent control

The roll caliber settings are continuously monitored indirectly via our systems. In case of deviations, you will be informed in real time and can take appropriate countermeasures.

"LAP's most modern measuring and inspection systems guarantee consistently high quality in the production of round long products and ensure that the high quality requirements of customers worldwide are met."

Martin Dronsek, Head of Business Unit at LAP



We advise you from ideation phase through the system design to the optimization of the ongoing operation. We will accommodate the regulations and standards for your business, your special requirements, and the economic conditions.

Project management

We cooperate with you to create a project plan and we synchronize our actions to suit your time frame. We provide the engineering, production, installation and commissioning as scheduled.


Before installation, we always test your system at our site. We coordinate the installation date with you to minimize or completely avoid downtimes. Integration into your production environment is then completed quickly and easily.


We start up your new measuring or projection system in the real production environment. In doing so, we handle the fine-tuning and carry out all tests necessary for acceptance.


We ensure that your system delivers the desired performance for years to come. You receive software updates and information about technology and service, andin addition to that, we offer cyclical inspection and maintenance of our systems.


Our worldwide service and partner network supports you anytime, anywhere. Troubleshooting is supported by remote access or local evaluation. Depending on the system, repairs will be carried out on-site or at LAP.
