Hi bro, no extra charge if it's a normal square,rectangle cut..it's base on dimension and thickness only, unless if you've requested for polishing, custom shape with curves, cut outs, bending etc..charges are depend on complexity of the cuts involved . if you wish to know more or would like me to quote a price for your request, please let me know..no problem if people just asking for a price quotation..it's a must tbh
