Technical details
Type of joints
The joints are made of brass coated steel. The steel rivet is visible and reinforced with supporting washers for added strength. The joints are greased with mineral Vaseline for comfortable use of the ruler.
Surface slats coat
Double-layered water- soluble paint. UV environmentally friendly coating of the top layer protects the ruler from the effect of thinner. UV coating enables the wrong print to be washed away easily and replaced with different one.
Ruler flat space
The joints are seamlessly integrated into the wooden structure, creating a flush surface. The adjacent wooden components align seamlessly to form a unified and compact surface, providing an ideal canvas for flawless prints.
The joint design has been refined over time for optimal durability and functionality. The use of steel with a brass coating, along with Vaseline lubrication, ensures a smooth and reliable running mechanism.
Variants of scales
The Perfekt 10 is manufactured as standard with a metric duplex scale. In addition to this standard version, Metrie also produces scales with deliberately unmarked areas for advertising or informational printing, as well as customer-specific graduations for OEM and special applications. The scales are printed directly onto the prepared wooden segments at the Metrie factory.
Duplex Scale – mm/cm
Standard version with a metric millimetre and centimetre scale. The graduation marks run along the upper and lower longitudinal edges of the wooden segment, while the numbers are positioned between them. This ensures that the scale remains clearly legible along its entire length without interrupting the measuring function with additional blank areas.
Scale with a Blank Upper Area
The graduation marks and numbers are deliberately omitted from the upper area of the wooden segment. This creates additional blank space for short advertising or informational details, such as a telephone number, email address, website address or company name. The metric measuring scale is retained along the lower part of the segment.
Centre-Strip Scale – Scale with a Blank Central Area
The numbers and graduation marks are omitted from the central area of the wooden segment.
Custom Graduations to Customer Specifications
For OEM and special projects, alternative graduations can be manufactured following technical assessment. Possible options include inch scales, combined metric and imperial divisions, or customer-specific measurement and marking systems. The graduations, numbering and blank areas are adapted to the requirements of the intended application.
Colour versions
The Perfekt 10 is manufactured in several standard colour finishes. The wooden segments are coated at the Metrie factory and then sealed with a UV-curing lacquer layer. In addition to the standard colours, customer-specific finishes in Pantone colours are available for advertising, OEM and larger production runs. Feasibility depends on the required colour, order quantity and technical specifications.
White
Standard version with white-coated wooden segments. The light surface provides high contrast with the black and red scale markings and is also well suited for coloured advertising printing.
Yellow
Wooden segments with a continuous yellow coating. The black and red scale markings remain clearly legible against the coloured surface.
White and Yellow
Combined colour finish with white and yellow areas. It provides additional visual differentiation of the folding rule and can be coordinated with the design of the advertising print.
Natural Wood, Clear Lacquered
The natural structure of the wood remains visible. The wooden segments are coated with a transparent lacquer, preserving the wood colour and grain while protecting the surface.
Custom Pantone Colour
For advertising and OEM production runs, the wooden segments can be manufactured in customer-specific Pantone colours following technical assessment. This allows the base colour of the folding rule to be matched to the customer's corporate design or brand colour.
