Yes. Our PU urethane dumbbells are specifically engineered for commercial gym environments. The odor-free polyurethane coating is extremely durable, resistant to cracking and peeling, and easy to clean. Over 200 commercial gyms worldwide use this model, with some facilities reporting 5+ years of daily use without coating damage.

Peso tolerance is ±2% per dumbbell, exceeding commercial gym industry standards. Each dumbbell is individually weighed during production and laser-engraved with the exact weight. We can provide batch weight inspection reports for large orders.

Yes. We offer full OEM services including laser-engraved logos on each dumbbell end, custom PU colors (Pantone matching), and custom printed packaging. Our design team can help you create mockups before production. MOQ for OEM is 50 pairs per color/design.

MOQ for standard orders (no customization) is 10 pairs. For OEM orders with custom logo/color, MOQ is 50 pairs per SKU. Sample orders of 1-2 pairs are available at premium pricing for evaluation purposes — contact us for sample pricing and availability.

PU urethane is significantly more durable than rubber coating — it resists cracking, peeling, and UV damage much better. PU is also completely odor-free (rubber can have a strong chemical smell), easier to sanitize, and has a premium matte finish. For commercial gyms, PU dumbbells typically last 2-3x longer than rubber-coated ones. See our full comparison article for details.

★★★★★

Marcus T.Gym Owner, Los Angeles

"Outfitted our gym with 20 pairs of these PU dumbbells. Zero odor, premium feel, and after 2 years of daily use they still look brand new. Best dumbbells we've ever used — and we've tried all the major brands."

★★★★★

Sarah K.Distributor, UK

"Been importing ZEALLSPORT PU dumbbells for 3 years. OEM laser engraving is clean and precise, customers love the quality. Lead times are consistent and the team is responsive. The PU coating really does last much longer than rubber."

★★★★☆

David R.Hotel Procurement, Dubai

"Installed a full set in our hotel fitness center with custom logo engraving. Guests compliment the equipment regularly. Only note: the 50kg pair is quite heavy to move, but that's expected. Would order again for our next property."
