LeadStrong IPF Competition Plate
The LeadStrong IPF Competition Plate is a certified competition-grade weight plate developed based on the technical specifications of the IPF (International Powerlifting Federation) and WorldPowerlifting. This IPF competition plate has obtained equipment certification from both IPF and WPC/IN, and is available in seven weights: 1.25 kg, 2.5 kg, 5 kg, 10 kg, 15 kg, 20 kg, and 25 kg. All sizes are manufactured from Q558 polyester cast iron using a mold and sand casting process, giving the ductile iron body extremely strong compressive resistance. The surface is finished with a high-temperature baked paint spraying process for strong powder adhesion and a durable color-coded appearance.
CNC lathes and CNC machining centers are used to precisely control the appearance, size, and weight of each IPF competition plate. Weight tolerance is ±10g for the 1.25 kg–5 kg sizes and ±0.25% for the 10 kg–25 kg sizes. Every plate is individually test-weighed before leaving the factory. The 1.25 kg and 2.5 kg sizes are sold as a pair; the 5 kg–25 kg sizes are sold per piece.
