It’s interesting how coil ID dimensions can feel like trying to find the right size bowl for cereal — too small and it overflows, too big and it’s a waste! I find that standardizing on certain sizes can really streamline operations. Has anyone here seen a noticeable impact on lead times with the 20-inch coils versus the usual sizes?

Standardizing coil IDs can definitely streamline operations, but it’s like choosing a pizza size — sometimes you need a little flexibility for those unique projects. Maybe exploring hybrid sizes could help? @mentioning everyone involved in these discussions might spark some fresh ideas.

I’ve noticed that coil dimensions can impact lead times significantly — some projects just require that perfect fit! Have any of you experimented with custom diameters? :hammer_and_wrench:.
