Gauge Thickness RFQ Conversion Matrix
A narrow gauge thickness RFQ conversion matrix for converting gauge numbers into material, mm thickness, strength, output format, tolerance, slitting or CTL route, and model fit.
A gauge thickness chart is useful only when it leads to a clear equipment specification. Gauge numbers change by material family, so an RFQ should convert gauge to millimeters or inches and then add material grade, strength, coil width, coating, surface requirement, output format, and tolerance target.
This page is a narrow gauge-to-RFQ conversion matrix in the MaxDo topic network. It owns only the conversion from gauge language into engineering data: material family, actual millimeter thickness, strength, coating, output format, tolerance, and model-boundary evidence. It is not a material behavior support page, not the coil-processing workflow hub, and not a slitting or CTL product page.
For material behavior beyond gauge conversion, use the MD series material compatibility checklist. For the main workflow route, use the sheet metal coil processing main workflow hub. For slitting equipment context, use the metal slitting line core page. For CTL station context, use the cut-to-length process main page.
Gauge Must Be Converted by Material
The same gauge number can mean different thicknesses for carbon steel, stainless steel, aluminum, and galvanized material. Always provide the material family and the actual thickness range in millimeters. If a buyer only says “16 gauge,” the equipment supplier still needs to know whether the coil is mild steel, stainless steel, aluminum, or coated steel.
| RFQ input | Why gauge alone is not enough |
|---|---|
| Material family | Gauge tables differ across steel, stainless, aluminum, and galvanized material. |
| Thickness range in mm | Defines line load, leveling need, blade setup, and model boundary. |
| Strength or grade | Changes cutting force, burr risk, tension, and wear. |
| Coating or surface finish | Controls roller contact, guide material, handling, and packing protection. |
| Output format | Determines whether the project belongs to slitting, CTL, or a combined workflow. |
Use Gauge as a Starting Point, Not a Specification
Gauge can help an operator or buyer describe a familiar material, but a machine supplier should quote from exact engineering data. Provide minimum thickness, maximum thickness, typical running thickness, coil width range, coil weight, ID, OD, material grade, strength range if available, coating, surface risk, and finished output requirements.
Connect Thickness to the Process Path
After thickness is converted, choose the process path. If the finished product is narrow recoiled strip, use the metal slitting line process guide. If the output is flat sheet, use the cut-to-length process guide. If the buyer is still deciding between strip and sheet output, use the slitting vs CTL order-mix guide and the slitting vs blanking decision map.
Map Thickness to Model Boundaries
Thickness range helps define model fit, but it should not be used alone. Thin-gauge work may still require careful surface protection, separator setup, and recoiling control. Heavy-gauge work may require stronger line load, wider model boundaries, and different tooling decisions. For wide or heavy slitting model decisions, use the MD-1650 vs MD-2200 model boundary checklist. For 1350mm projects, use the 1350mm slitting line RFQ checklist.
Gauge-to-RFQ Checklist
- Material family, exact grade, coating, temper, surface finish, and strength range if available.
- Gauge reference plus exact thickness range in mm or inches; never gauge alone.
- Incoming coil width, coil weight, ID, OD, future width range, and site handling constraints.
- Output format: slit coils, flat sheets, blanks, or a workflow requiring both width and length conversion.
- Quality target: width or length tolerance, burr, flatness, camber, surface marks, stacking, or recoiling requirement.
Route Thickness Data to Equipment Pages
For slitting equipment, compare the metal slitting machine category, including MA-850, MA-1350, MD-1650, and MD-2200. For CTL equipment, compare the metal cut-to-length line category, including CT-1350 y CT-1650.
If the project is non-standard, use the custom machinery engineering scope checklist. To request a thickness-based equipment review, send MaxDo your material family, gauge reference, actual thickness range, coil width, strength, coating, output format, tolerance target, and model preference through the contact form.
