To manufacture nail plate trusses, rafters, purlins, and other timber components must be positioned accurately and joined precisely. At Natec GmbH, which produces nail plate trusses in a wide range of sizes and shapes, alignment was previously done using measurement systems or physical templates. This required time-consuming setup. Accuracy was also limited, especially for large assemblies, so even minor deviations led to fitting inaccuracies, rework, and material waste. That is why Natec uses Z-LASER laser projectors to optimize positioning and assembly in production.This application demonstrates how laser projection helps standardize workflows and supports consistently high process quality in nail plate truss manufacturing.
What are nail plate trusses?
Nail plate trusses are prefabricated timber framework structures in which individual timber members are connected using steel connector plates (nail plates) that are pressed into the wood. This enables lightweight yet highly load-bearing roof and ceiling structures with large spans. Dimensional accuracy and quality depend on the nail plate connections being positioned and pressed at the nodes precisely in accordance with the construction file.
Full-Scale projection: LP-HFD2 at Natec
To enable precise and repeatable positioning, Natec uses the Z-LASER LP-HFD2 in its timber production environment. Based on the existing construction file, the laser projector generates a full-scale laser contour and projects it onto the entire work surface. This clearly displays the exact positions of the press blocks, wooden planks, and nail plates. Operators can align components quickly and reliably along the projected laser lines.
In the next step, the C-press moves fully automatically to the designated positions and presses the nail plates into the wooden planks at the defined points. By eliminating error-prone physical templates, time-consuming manual remeasurement and unnecessary setup time are reduced, even for complex constructions.
Connected multi-projector system for large work Areas
To cover complete nail plate trusses, several laser projectors can be connected in a multi-projector system. This enables large projection areas, from small setups to large constructions that can cover an entire production hall.
Benefits of laser projectors in timber construction
In timber construction, laser projectors offer more than basic positioning support. Used as a wood laser machine for visual guidance, the Z-LASER LP-HFD2 supports Natec’s production in several ways:
- Significant time savings: Projected laser lines reduce time-consuming manual remeasurement and help cut unnecessary setup time, even for complex constructions.
- High precision: Visual guidance reduces measurement errors and supports consistently high product quality.
- Fewer positioning errors: Clear projections reduce the risk of misplacement of timber components and nail plates.
- High flexibility: Different shapes and constructions can be produced quickly without the need to build new templates or jigs.
Conclusion: Quality and efficiency through laser projectors
The use of the Z-LASER LP-HFD2 at Natec shows how laser projectors enable efficient and repeatable workflows in nail plate truss manufacturing: full-scale projections on the work surface replace error-prone mechanical templates and make component positioning faster and more reliable, even for changing shapes and large-scale constructions. The result is repeatable positioning and assembly with less time-consuming manual remeasurement and reduced setup time.

Frequently asked questions
Nail plate trusses are prefabricated timber framework structures connected using steel connector plates (nail plates) that are pressed into the wood. They enable lightweight yet highly load-bearing roof and ceiling structures.
Laser projectors display full-scale contours and component positions directly on the work surface. This reduces manual measuring and marking and supports faster, more accurate positioning.
For this application, Natec uses the Z-LASER LP-HFD2 to project full-scale contours based on the construction file.
Key benefits include reduced setup time, fewer positioning errors, consistently high quality, and high flexibility since different shapes can be produced without new templates or jigs.
A laser projector can be referred to as a “wood laser machine” in timber applications, but it is not used for cutting. Unlike material-processing lasers, it does not machine the wood. Instead, it is used for visual guidance: it projects information onto the work surface and serves as a positioning aid to make manual steps faster and more accurate.
