Co-operative production STROS

Except of access equipment manufacturing, STROS – Sedlčanské strojírny, a.s. is engaged in co-operative production. Thanks to technological equipment investments, we are now able to offer modern technologies such as laser cutting, CNC folding, CNC machining, drilling, manual and machine welding, aluminium welding, sand-blasting and painting. Jobs are performed on most modern machines with brand names KOVOSVIT MAS, TRUMPH, KESEL, ABB, Fronius, EST, etc.
