The weight plates can be divided into three categories: coated ("rubberized"), solid ("bumper"), technical.
The first are metal weight plates covered with rubber or polyurethane, the second are weight plates entirely made of rubber or polyurethane. The combination between these elements: coated or solid, rubber or polyurethane, determines the features, destination of use, production cost; polyurethane has the highest production cost. The technical weight plates, on the other hand, are sui generis discs, i.e. they are produced according to their solutions to meet specific technical requirements.
If we consider the weight plate simply as a weight, the use of metal is certainly the most suitable solution, in terms of cost but also in terms of size, bulk, and the possibility of loading them on tools and racks. Considered instead in the field of weighing, the weight plate must also be resilient (resisting dynamic forces, i.e. the impact on the floor, absorbing energy with elastic deformations), the use of rubber fulfills this function. Finally, if evaluated in the context of a tool room, the weight plate must also have aesthetic, accident prevention, and handling characteristics, with comfortable grips, as in metal weight plates covered with rubber or polyurethane.
Starting from this brief premise we analyze the main properties of the various models of weight plates that we produce.
