My employer makes fabricated sheet metal parts and assemblies. We used to quote 2-4 weeks lead time. It's been 8-12 weeks for some time now. Some materials/gages are difficult to get, cost more, and have longer lead times from the mill or distributor. Components for machine maintenance/repair are at least as long a lead time. We keep hearing that it will get worse, not better. It's across the board, all industries, economy and world-wide.
