Salary struture with multiple level

How do I, implement a salary with multiple grade level. Example level 1 step 1, level 1 step 2 …level 1 step 10.

Level 3 step1 …level 3 step10

Do I have to create different grade with level 1 step 1 and salary struture level 1 step 1…

This will lead to too many grade level on the system.

Is there a better way?
