Sheet Metal Thickness Reference for Your RFQ

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.

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.
