Wholesale Calibrated Steel Plate-Weight Plates for Professional Gyms

High-quality calibrated steel plates available for bulk orders, ideal for gyms and fitness centers.

OKPRO's Calibrated Steel Plates are high-end weight products developed specifically for commercial gyms and professional training centers. Each plate is individually weighed and tested before shipment to ensure precise and consistent weight. These precision-calibrated steel plates are machined from solid, high-strength steel and undergo multiple precision weighing and adjustments to maintain a weight tolerance within ±10g, meeting the stringent requirements of international powerlifting competitions and professional training. Their high-density construction allows for a thinner plate for the same weight, allowing for more weight to be loaded onto the bar, helping athletes push their limits.
The plate's surface is electroplated or powder-coated for excellent rust and corrosion resistance, creating a metallic finish. Each plate is clearly color-coded for easy identification and loading and unloading. The steel construction ensures stability and consistency over time, preventing weight deviations due to drops or wear.

OKPRO offers a full range of weights from 0.25kg to 25kg, suitable for different training and competition levels. We offer OEM/ODM customization services, including custom logo laser engraving, surface color customization, and packaging design. All products undergo rigorous factory testing to ensure dimensional accuracy, appearance quality, and consistent weight calibration standards.

With years of professional manufacturing experience and stable global supply capabilities, OKPRO is dedicated to providing high-quality steel barbell plate solutions for commercial gyms, powerlifting clubs, training centers, and sports equipment distributors. Whether for competition-level applications or everyday training, these calibrated steel plates ensure precise and stable performance.
