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

Whether in the construction industry, automotive industry, shipbuilding, or machine and plant construction: bar steel and rebar are processed in various industries. To meet the complex industrial requirements, LAP offers smart measurement technology to meet complex industry requirements for the inline measurement of bars and reinforcing steel in the rolling mill and for downstream process steps.

With the LAP laser measurement, you can monitor all rods along the entire length to comply with the requirements for diameter, contour, and straightness. Deviations are detected immediately, the operator can quickly and precisely intervene in the production process to make corrections.

What can you measure with our systems?

Surface and rolling defects
Length
Straightness

Rebar

Diameter from core and projected cross section at several points
Cross rib height in several places
Longitudinal rib height and width
Relative rib area
Weight per meter and total weight
Rolling defects
Length

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.

Services

Consulting

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.

Installation

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.

Commissioning

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.

Maintenance

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.

Repairs

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.
