FAQ

When it comes to dumbbells, rubber and urethane dominate for a reason—but there’s a difference. Both are durable, but rubber dumbbells offer excellent shock absorption and floor protection, while urethane provides a premium look and higher resistance to wear and color fading.
With quality construction and proper care, Hammer Strength dumbbells are built to perform for years in high-volume environments, maintaining both appearance and performance.
No. The rubber coating helps protect both the dumbbells and surrounding equipment, reducing noise, scuffing, and floor impact during daily use.
UV-resistant dumbbells maintain their color, finish, and structural integrity even in sunlit or high-exposure areas. This prevents fading, cracking, and chalking—helping facilities preserve a professional look and reduce replacement costs over time.
New dumbbells may have a light protective oil coating to ensure they arrive in top condition. This coating will naturally wear off after a few weeks of use, but you can speed up the process by wiping them down with a dry rag. Rest assured, they’re ready to perform from day one. 
Our 4-Sided dumbbells cannot be customized at this time.
