Roll grades
- Adamite rolls — tough, crack-resistant rolls for roughing and intermediate stands.
- Pearlitic and SG (nodular) iron rolls — a good balance of wear resistance and strength for intermediate stands and section mills.
- Indefinite chill (ICDP) rolls — hard working layer for finishing stands and seamless tube mills.
- High chrome iron and steel rolls — high wear resistance and good surface for intermediate and finishing stands.
- Cast steel rolls — for heavy roughing duty where breakage risk is high.
- HSS rolls — high speed steel for finishing and pre-finishing stands, several times the tonnage of cast iron.
- Tungsten carbide roll rings — for wire rod blocks and rebar finishing.
Mills we supply
Rod and bar mills — billet through finishing stands, including rebar. Section mills — breakdown and universal stand rolls for angles, channels, T-sections and beams. Seamless tube mills — roughing, MPM / PQF and sizing / stretch-reducing mill rolls.
How we choose the grade
We ask for the stand position, roll size, current grade and hardness, tons per campaign and the reason rolls are taken out (wear, cracks, spalling, breakage). From this we propose the same grade or an upgrade, and we quote both when an upgrade makes sense. Our article HSS rolls vs cast iron rolls explains the trade-offs.
Quality control
Chemical analysis, ultrasonic testing of the bond and body, hardness across the barrel, full dimensional inspection and spec-compliance check before shipment. Test certificates go with every roll.
Frequently asked questions
Do you supply rolls to OEM drawings?
Yes. We make rolls to your drawing or to the mill builder's drawing, and keep the drawing on file for repeat orders.
What is the minimum order?
There is no fixed minimum. We quote single rolls as well as full stand sets.
Where are the rolls cast?
In foundries in India, Southeast Asia and Turkey that we have vetted for each grade. You contract with Midland Heavy Industries LLC in the USA.
