Which grade is reserved for specific areas requiring the highest levels of finish and workmanship?

The option indicating "Premium grade" is reserved for specific areas that require the highest levels of finish and workmanship. This grade is associated with superior quality materials and exceptional craftsmanship, often used in high-end projects where aesthetics and durability are paramount. Premium grade products showcase intricate details and finishes that satisfy rigorous aesthetic standards and are typically used in visible areas of a building or installation, such as in luxury homes, upscale commercial projects, or distinctive architectural elements.

In contrast, other grades like economy, custom, and standard may not emphasize the same level of detail and quality. Economy grade is aimed at cost-effectiveness and often features simpler designs with less attention to finish. Custom grade represents tailored solutions but can vary widely in quality, while standard grade usually provides a balance between quality and affordability without the premium finishes found in premium grade.
