The shelves are 18 inches wide and designed with a 1-inch steel lip, which enhances their strength and stability. This lip serves multiple purposes:
 
Prevents items from slipping off the shelf, ensuring that everything stays securely in place.
Catches minor spillages when storing liquids, helping to contain any mess and maintain a clean storage area.
 
These shelves are perfect for both general storage and areas where you may need to keep items like liquids safely stored.
