Roll grooving machines require different roller materials for different pipe conditions. This article compares plated rollers and stainless steel rollers used on Gruvmaster roll grooving machines, focusing on thin-wall pipe applications, groove quality control, durability, and cost considerations. Selecting the correct roller set based on pipe wall thickness helps improve grooving consistency and overall processing reliability.

Photos from the Gruvmaster factory show roll grooving machines during final assembly. At this stage, machines undergo alignment, fastening, fine adjustment, and inspection. Each unit is assembled by hand following a consistent process to ensure stable structure, smooth operation, and reliable quality before shipment.
