Composite weight plate Springos 15 kg, 31 mm center hole, 37 cm diameter, 7 cm thick

Springos composite weight plate 15 kg with a 31 mm center hole, 37 cm diameter and 7 cm thickness is a compact, durable solution for strength training on standard 31 mm bars. The plate has a polypropylene outer coating and bitumen filling that provide solid mass and reduced noise during use. Finished in black with the Actiget® logo, this plate is suitable for home gyms and commercial settings where space-efficient, stable loading is required.

Advantages

The composite construction combines a polypropylene outer layer with bitumen filling to achieve a consistent 15 kg mass while minimizing impact noise and protecting floors. Its compact 37 cm diameter and 7 cm thickness allow closer gym station placement and easier storage compared with larger-diameter plates. The 31 mm center hole is compatible with standard Olympic-style bars and keeps the plate firmly centered for balanced lifts. The black finish resists visible wear and is simple to maintain.

Suitable for

• Barbell deadlifts, squats and presses on 31 mm bars
• Home and commercial gym strength training
• Progressive loading and weight stacking for compound lifts

How to use

Slide the plate onto a compatible 31 mm bar until it rests securely against the collar or other plates. Ensure the bar is supported and balanced before performing lifts. For safe handling, lift plates using proper posture and, if needed, wear gloves to improve grip on the polypropylene surface. When loading multiple plates, arrange them symmetrically on both sides of the bar to maintain balance. Store plates on a horizontal rack or vertical stand designed for composite plates to avoid uneven pressure during storage.

Usage recommendations

Inspect plates periodically for surface damage and ensure the center hole is free of debris to maintain smooth mounting. Avoid dropping the plate from significant heights to preserve the polypropylene coating. Clean the surface with a mild detergent and a damp cloth; do not use strong solvents that could damage the outer layer.
