A clear request for quotation saves days of back-and-forth and gives you quotes you can compare line by line. This checklist covers what to send when you buy mill rolls.
For every roll
- Drawing number and the drawing itself (PDF or DWG). If you use the mill builder's drawing number, include it too.
- Main dimensions: outside diameter × barrel length × total length.
- Grade: for example adamite, pearlitic, SG iron, indefinite chill, high chrome, cast steel, HSS or tungsten carbide.
- Hardness range on the barrel, written as a range — for example 55/60 HSc.
- Quantity, and yearly consumption if you want a supply agreement.
- Stand position and mill type — roughing, intermediate or finishing; bar, rebar, rod, section or tube mill.
Useful extras
- Current roll life (tons per campaign or per mm of diameter) and why rolls are taken out — wear, cracks, spalling or breakage.
- Machining state: rough-machined, finish-machined or grooved, and who does the grooving.
- Special features: labyrinth grooves, keyways, centres, neck details.
- Required documents: test certificates, UT reports, third-party inspection.
- Delivery terms and the mill address.
Keep line items consistent
List one roll type per line, in the same order every time you send the RFQ. When several items share one drawing, say which stands each line is for. This makes it easy to compare quotes from different suppliers and to repeat the order later.
Upgrades
If you want to try a better grade, ask for it as a separate line next to the current grade. You get both prices and can decide from cost per ton, not price per roll.
See our mill rolls page, or send your RFQ — we reply within one business day.
