Pintalaatu
Pintalaatu is a term used in Finnish manufacturing to describe the overall quality of a material surface, including its texture, smoothness, and appearance. It encompasses factors such as roughness, waviness, lay (the predominant direction of surfaces), and the presence or absence of defects. In practice, pintalaatu is the functional and aesthetic suitability of a surface for its intended use, and it is distinct from the bulk properties of the material.
The concept aligns with the broader English term “surface quality” or “surface finish.” It is assessed using
Standards and specifications play a central role in defining pintalaatu. Internationally, surfaces are described via standards
Applications span automotive, aerospace, mechanical engineering, woodworking, plastics, and electronics, where adequate pintalaatu affects wear, fatigue
