Lahtritesse

Lahtritesse is a Dutch-language term used in technical contexts to describe the thickness of a flat sheet or plate. The term is commonly applied to materials such as metal, glass, wood, plastic, and composite sheet materials. It is defined as the distance between the two parallel surfaces of the material and is usually expressed in millimeters, though in some contexts inches may appear.

In practice, lahtritesse is a key parameter for design and manufacturing, affecting strength, weight, fitment, and fastening. It is specified in product specifications, drawings, and catalogs, and is subject to tolerances determined by the material, production method (such as hot-rolled, cold-rolled, tempered, molded, or extruded), and applicable standards. Manufacturers may publish nominal thickness as well as toleranced values, and customers may require precise thickness control through quality assurance processes.

Measurement is typically performed with micrometers or calipers for sheet materials, with non-contact methods (laser or ultrasonic) used for larger or finished parts. In procurement, lahtritesse must be matched to joints, clearances, and compatibility with coatings, treatments, and fasteners. See also: thickness, sheet, plate, gauge, tolerances, standards.
