Pada prosess pengerolan, benda dikenai tegangan kompresi yang tinggi yang berasal dari gerakan jepit roll dan tegangan geser-gesek permukaan sebagai akibat gesekan antara roll dan logam. Selama proses roll, tegangan ini mengakibatkan terjadinya deformasi plastis. Produk akhir dari proses ini adalah logam plat dan lembaran (sheet), dimana umumnya plat mempunyai tebal lebih dari ¼ in. Lembaran umumnya mempunyai ketebalan kurang dari ¼ in. Tujian utama pengerollan adalah untuk memperkecil tebal logam.Biasanya terjadi sedikit pertambahan lebar, penurunan panjang mengakibatkan pertambahan panjang.
