Introducing the SAIT Weightlifting Company, who specialise in gym equipment made from recycled material. Our New weight plate collection includes 4kg,5kg,6kg,7kg,8kg,9kg, and the 10kg pairs. This increased range of weight plates provides you with a more tailored experience. We offer a new green alternative to weight plates. Our weight plates are made using recycled cast iron brake discs. No plastic, No concrete, No melting! Priced competitively. We are considerably less expensive than other cast iron weight plates and very similar in price to the lesser vinyl alternatives.
