Non-contact measurement systems for the quality assurance of steel profiles

With LAP laser measurement systems, you can determine the dimensions of your steel profiles without contact during the rolling process and receive the measurement results in real time.

When manufacturing profiles made of steel and non-ferrous metals, it is important to continuously monitor the entire dimensions and the profile cross-section during the rolling process. The more information you have about the dimensions, the more effectively you will produce.

LAP measurement systems help you meet the given product requirements, they immediately alert you to tolerance violations, and provide reliable documentation. Optimize your process control with us and sustainably increase your product quality and, with it, the satisfaction of your customers.

Your benefits

Less scrap

By permanently monitoring the profile geometry, you can demonstrably save material and benefit from lower reworking costs.

Proven quality

All measurement data is stored in a database. This means that at any time, you can call up and prove relevant dimensions, angles or lengths of the products already produced.

Seamless integration

Our measuring frames and the PC-based system can be easily connected to the master computer. Users can intervene optimally in the ongoing rolling process in the sense of Industry 4.0.

"Absolute customer focus means for us above all being close to the customer and his requirements. Our laser measurement systems for your steel profiles offers maximum accuracy and process control in safe working conditions."

Our services


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 all on schedule.


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.
