The minimum thickness of the metal plate in the recessed area being identified as 12mm is rooted in industry standards and practices related to structural integrity and safety. A thickness of 12mm ensures that the plate can adequately withstand various loads and stresses that may be applied in practical applications, particularly in environments where durability and resistance to deformation are critical.

Thicker plates generally provide greater strength and longevity, especially in recessed areas that may be subject to wear, impact, or other mechanical forces. Utilizing a 12mm thickness reduces the risk of bending or warping under load, promoting overall reliability in engineering designs. Standards often recommend this minimum thickness as it strikes a balance between sufficient strength and material efficiency, preventing excess weight or cost without compromising performance.

This option aligns with the requirements needed in applications such as structural components, machinery housings, or fixtures where both safety and performance are paramount.
