If you mean the sort of cement resistors that I think you do, the problem I see is that they are not designed to transfer the heat to a metal surface. Rather they are designed to be cooled by convection. The type of power resistor that has a metal case intended to be bolted to a heatsink would be more suitable, but also more expensive.
Power resistors are not cheap. You may find that it costs less to order a silicone bed heater to your own size, voltage and power specifications from one of the Chinese companies that specialise in these, such as Shenzen Ali Brother Technology. The 300mm 230V 350W one they made me cost about $35 AFAIR.

Thank you very much for the tip. Could you share some pictures of your project? Also, could you tell what wire resistance did you use and the length? Thanks!Quote

look for silicone blanket wire on aliexpress..
it is basically silicone encased nichrome wire. u just need to stick it to the bottom of the plate with a liquid silicone gasket and vola instant heated bed... i have 2 such bed running on 220 v... only take care to coat the bed with a insulating material like polymide before putting the wire or in case of short u will have high voltage running through your plate..
