Several ANSI/BHMA standards categorize hardware items into different product grades (grade 1, 2, or 3, with grade 1 being the highest) based on:
- Progressive performance benchmarks set in each applicable ANSI/BHMA standard.
- The BHMA® product number associated with the item.
- Additional classification information, including the primary material used, product category, and the specific function of the hardware item.
