Several aspects are considered during their manufacturing:</p><h3 data-section-id="1oi5wi2" data-start="2504" data-end="2533">1. Material Composition</h3><p data-start="2534" data-end="2708">Rollers are typically made from <strong data-start="2566" data-end="2592">high-grade alloy steel</strong> or hardened steel. This ensures durability, resistance to wear, and the ability to handle high-pressure operations.</p><h3 data-section-id="1ftcth7" data-start="2710" data-end="2735">2. Surface Hardness</h3><p data-start="2736" data-end="2892">To withstand continuous friction with steel bars, rollers are heat-treated to achieve high surface hardness. This minimizes wear and extends their lifespan.</p><h3 data-section-id="n9yrhv" data-start="2894" data-end="2925">3. Roller Shape & Profile</h3><p data-start="2926" data-end="3122">Rollers are designed with specific grooves or smooth surfaces depending on the type of bar being processed.
