Metal Slitting Buyer RFQ Readiness Checklist
A metal slitting buyer RFQ readiness checklist for material data, coil envelope, strip program, tolerance, setup rhythm, plant constraints, FAT/SAT evidence, and product routing.
A metal slitting RFQ should be sent only after the buyer can describe the production burden in a way that a supplier can size, route, quote, and prove. If the inquiry only says “we need a slitting line,” the quotation will usually hide assumptions about material, coil width, strip count, tolerance, setup rhythm, plant layout, controls, and acceptance testing.
This page is the metal slitting buyer RFQ readiness checklist in the MaxDo topic network. For the full process, specification, and ROI background, use the metal slitting line guide. For industrial project scope, use the industrial slitting line project scope checklist. For platform class decisions, use the industrial slitting platform-class decision record. This page focuses only on whether the buyer has enough RFQ data before asking suppliers for a quotation.
Use This Page as the RFQ Gate
The RFQ gate is different from a supplier scorecard, a product comparison, or a general buying guide. It asks one question: can a supplier quote the same machine scope after reading the file? If the answer is no, the inquiry should be tightened before model routing begins.
| RFQ data block | Minimum buyer input | Why it matters |
|---|---|---|
| Material package | Grade, thickness range, strength, coating, surface sensitivity | Controls knife, arbor, tension, protection, and speed assumptions |
| Coil envelope | Coil width, coil weight, ID, OD, incoming condition | Controls decoiler, handling, entry support, and plant logistics |
| Strip program | Finished widths, strip count, trim, tolerance, burr limit | Controls slitter tooling, separator setup, recoiling, and scrap plan |
| Operating rhythm | Changeovers, batch size, operators, target throughput | Controls automation, recipe, HMI, and setup-time expectations |
| Proof plan | FAT/SAT samples, inspection method, acceptance owner | Turns quotation claims into measurable delivery evidence |
Attach the Material Package Before Asking for Price
The supplier needs the actual material burden, not only a product name. Record material grade, thickness range, yield strength, tensile strength, coating, hardness, surface sensitivity, edge condition, and any future material family that the line may need to process. If the inquiry uses gauge language, convert it first with the gauge thickness chart.
For material-family boundaries across MaxDo slitting and shearing equipment, use the MD series material compatibility checklist. For steel-specific evidence, use the steel coil slitting machine selection checklist. For light-gauge custom work, use the light gauge slitting customization RFQ checklist.
Define the Coil Envelope and Plant Constraints
The coil envelope prevents a supplier from quoting a line that fits the strip program but fails in handling. Record incoming coil width, maximum coil weight, coil ID and OD, surface protection, entry route, crane or forklift limits, floor space, power, air, foundation, scrap path, packing route, and downstream equipment. If the plant is still comparing slitting with sheet output, use the slitting vs CTL ROI decision record before finalizing the RFQ.
If the scope mixes slit coils, CTL sheets, blanks, or flatbed laser work, first route the required output with the slitting vs blanking output-format decision map and the slitting vs flatbed output-format checklist.
Convert Product Demand Into a Strip Program
The strip program is the commercial heart of the RFQ. List the master coil width, finished strip widths, strip count, trim allowance, width tolerance, burr limit, camber target, finished coil ID and OD, separator method, packing standard, annual volume, batch size, and downstream customer or process. This allows the supplier to quote tooling, setup logic, separator layout, recoiler behavior, and inspection records instead of a generic line.
For tolerance wording, use the slitting width tolerance measurement protocol. For precision clauses that should be added to a purchase file, use the slitting precision RFQ clause checklist.
State Setup Rhythm and Control Expectations
A line that runs one repeat job every day is not the same project as a service-center line with frequent width changes. Record expected changeovers per shift, normal batch size, operator count, recipe needs, HMI language, reporting requirements, setup-time target, and what the plant expects from PLC, servo, tension, and monitoring functions.
Use the slitting line setup time reduction checklist if changeover time is part of the business case. Use the slitting line control upgrade roadmap if the RFQ must specify recipes, alarms, servo records, tension feedback, or production reporting.
Build the FAT and SAT Evidence File
The RFQ should name how the supplier will prove the line before shipment and after installation. Define sample material, test thickness, coil width, strip widths, line speed, width tolerance, burr limit, camber limit, surface condition, recoiling quality, setup-time target, inspection tool, deviation owner, correction method, and retest rule. A quotation without FAT and SAT evidence is not ready for reliable comparison.
- FAT evidence: material sample, strip plan, measurement records, control screenshots, speed record, and deviation log.
- SAT evidence: installation constraints, site utilities, operator training, acceptance owner, and production release record.
- Commercial evidence: warranty scope, spare parts, tooling assumptions, service response, and documentation handover.
Route the Ready RFQ to a Product Path
After the RFQ file is complete, start with the metal slitting machine category. Compact or narrower programs can compare MA-850. Mid-width service-center programs can compare MA-1350. Wider or heavier production burdens should review MD-1650 и MD-2200.
If the buyer is still choosing a supplier rather than a machine class, use the coil processing manufacturer evaluation scorecard before comparing final quotations.
Send a Ready RFQ to MaxDo
To ask MaxDo for a metal slitting line review, send material grade, thickness range, strength, coating, coil width and weight, finished strip program, tolerance target, setup rhythm, plant constraints, preferred model path, FAT/SAT expectations, and current bottleneck through the contact form.
