从China供应商批发进口Adjustable Dumbbell — FOB条款

The Adjustable Dumbbell from Shanxi A&r Industrial Trade Co., Ltd. is a selectorized weight system designed for commercial and residential strength training environments. The unit features a quick-change mechanism that allows users to adjust resistance levels without manually loading or unloading plates, reducing transition time between exercises. Construction uses metal alloy components with a protective finish to resist corrosion and surface wear during repeated use. The handle incorporates an ergonomic grip pattern to maintain secure hand positioning during high-rep sets. Standard configurations accommodate multiple weight increments within a single dumbbell footprint, addressing space constraints in boutique fitness studios and home gym setups.

The adjustment system relies on a dial or pin selector that engages discrete weight plates stored on a central rail or cradle. Typical plate materials include cast iron or steel composite with a machined flatness tolerance of 0.1 mm to ensure smooth stacking and minimal lateral play. The locking mechanism must withstand repeated drop testing to ASTM F1749 standards for stationary training equipment. Handle diameter typically falls between 28 mm and 32 mm to suit grip biomechanics for both male and female users. Plate faces are generally coated with rubber or urethane to protect flooring and reduce noise impact, though specific finish varies by production batch and target market.

These dumbbells serve personal training studios, commercial gym chains, hospitality fitness centres, and direct-to-consumer home fitness markets. Buyers should confirm the maximum weight capacity per hand, total plate inventory, and whether the connector accessory enables barbell configuration. The supplier lists FOB and CIF as available shipping terms, though buyers must verify current lead time, exact MOQ, and certification status directly with Shanxi A&r Industrial Trade Co., Ltd. given the zero percent response rate recorded on the profile.

Shanxi A&r Industrial Trade Co., Ltd. operates from No 258, Changzhi Road, Taiyuan, Shanxi Province, postal code 030006. The supplier holds a harbor trust tier on the platform, indicating a baseline verification level without advanced accreditation. The response rate shows zero percent with no recorded average response hours, which signals that direct enquiry may be necessary to assess current operational status and sales team availability. The company profile does not disclose factory ownership, production capacity, year of establishment, or employee count, so buyers should treat it as a trading company or intermediary rather than a confirmed manufacturer.

The listing emphasises space-saving design, durable construction, user-friendly mechanism, and versatile weight range, though no specific certifications, test reports, or factory audit documents are referenced in the source material. The supplier mentions that products meet international standards with certifications, but no certifying body, standard number, or scope is provided. Buyers sourcing adjustable dumbbells from this origin should request ISO 9001 or equivalent quality system documentation, plus material composition certificates for the metal alloy and coating substances, to ensure compliance with destination market regulations such as EU REACH or US California Proposition 65.
