under mount slides – super heavy duty?

I did my kitchen 3 years ago with some semi custom cabinets.
It has a peninsula with a 30 drawers with full extension undermount slides. We keep our pots and pans in this drawer.
The slides are starting to sag a hair. I am thinking i want to replace them with a higher end set of slides. I think the current ones are rated at 100 lbs.
Any recomendations for slides? I cant seem to find any with a higher then 100 lb rating.
thanks

100 lbs of pots and pans in any one full extension drawer is hard to believe. And you have 30? Can't you split these loads up a bit? Remember, slides have a load rating which is generally conservative of actual capacity.
At any rate, I've found good selection of heavy duty hardware here: https://www.cshardware.com/ and also Hafele.com
Drawer Slides
I've had good luck with Knap & Vogt slides. I've got a couple of drawers that are 28" wide and loaded with canned food are in excellent working order.

Please clarify this-----you have a 30 inch drawer that the slides sag. Wore out?
even with cast iron cookware, it shouldn't have. Contact the manufacturer and see if they're gracious or pricks.
Sorry the drawers are 30"
Sorry the drawers are 30" wide is what i meant i should of proof read my initial post.
I will reach out the cabintie manufacturer and see how responsive they are. Assuming they are not to helpful keep the recomendations coming.

When our kitchen was redone 6-7 years ago the guy installed sliding shelves in the lower cabinets. He didn't use undermount slides (no need, and nothing to mount them on), but side-mount units (with a lip under the edge) which attached to a plastic vertical rail, as some sort of "system". The shelves were custom-made to fit. We're very pleased with them.
Double them up. I have a gun cabinet that slides back into the wall and it is hanging on four 100# slides
