Sheet Metal Thickness Reference for Your RFQ
Specify sheet metal thickness in the same units on your CAD, drawing and RFQ so each supplier prices the same stock.
Nominal sheet thickness conversions
| Drawing thickness (in) | Equivalent (mm) | RFQ note |
|---|---|---|
| 0.032 | 0.8128 | Confirm minimum thickness if stiffness controls fit. |
| 0.040 | 1.016 | Confirm grade, temper and finish. |
| 0.060 | 1.524 | Confirm whether a nominal 1.5 mm alternative is acceptable. |
| 0.080 | 2.032 | Review bend radius and flange clearance. |
| 0.125 | 3.175 | Check how stock thickness affects the mating stack. |
Use these examples to prepare your request. Confirm stock and acceptance criteria for your project.
Before you send your RFQ
- Write the material grade and temper next to the nominal thickness. Gauge conventions vary by material.
- Specify sheet metal thickness tolerance where thickness affects function. Identify which unit controls if both are shown.
- Ask whether an alternate stock thickness changes the bend allowance, finish or fit before approving it.
