A 3 No. hole is 0.60 mm in SS 304, in brass and in copper. Garg Industrial Mesh does not change the chart for the metal. The metal follows the mill.
Which metal
| Metal | When mills ask for it |
|---|---|
| SS 304 | Rice, atta, dal and spice screens that stay wet and must not rust |
| Brass | The hopper or spice screen already in the mill is brass |
| Copper | The drawing or the old screen is copper |
GI and MS are not the metals on this mill chart. Architectural perforated sheet in other metals is a different range, patterns 01–29, and it is not a substitute for a numbered mill hole.
Why one shop for all three
A plant that runs an SS chamber and a brass spice screen can place both on one RFQ, with the hole number written against each. The counts are not translated between metals. G-25, G Block, Sector 9, Noida. Call or WhatsApp 9910238277.
