The stainless steel conveyor belts proposed by TRIMAT are made with a stainless steel sheet structure and with components compatible with the packaging and transport sectors subject to EFSA-FDA regulations. The straight modules, designed in different lengths, allow the user to choose the correct overall length of the stainless steel conveyor belt according to their transport needs. Furthermore, the stainless steel conveyor belts are offered in numerous standard widths so as to cover as much as possible the needs of transport without the need to resort to special set-ups, all to the advantage of the economy of the system. The shoulders, the structure to put it better, of the straight modules of the stainless steel conveyor belts offered by TRIMAT, are prepared for the assembly of the drive and return units without the need for modifications or special devices or devices, to the advantage of constructive economy. The straight modules can be concatenated in a theoretically infinite series: for this purpose the joints have been designed, the application of which between one module and the next of the stainless steel conveyor belt. takes advantage of the same arrangements provided for the assembly of the towing and return units, once again with the aim of reducing the items making up the BOMs as much as possible.
