Every low density industrial buildings product 9 freight every 2hours 24minutes.
And medium density industrial buildings product 9 freight every 1hour 12minutes.
And high density industrial buildings product 9 freight every 36minutes. It's going faster.
Low and medium buildings are fine if the traffic is fluent. They don't claim about shipping problem.
But high density buildings are keep claiming for shipping freights. Because their production speed is faster than their shipping speed.
I've build trade depots right next to them, but still have the problem.
Should I just destroy them out?
What can I do?

Industry buildings spawn trucks every hour (each building has its own timer).
Suppose a building generates a truck at 9:15. The next truck is scheduled at 10:15 and will not generate if the first truck isn't back yet. Then 11:15, 12:15, 1:15...
Trucks from different density industrial buildings carry different amounts of freight and look different.
If you get at least 8 trucks/day out of your building, you'll be fine.
If you want to maximize stability of freight shipments, make sure that the truck cannot leave the industrial area without passing a trade depot with available space in its freight shipping addon. (either side of the street, or right side of the avenue - nothing crosses avenue medians).
The real problem with HD industry buildings and shipments is the number of workers. Workers leave by the same exit as the freight. If the HD building has between 600 and 1620 workers, it could take hours for those workers to exit the building (and freight will wait). Solve this by making workers walk or take street cars (don't use buses as they will cause tears).
