Trans-Supply Blog – Road & Airport Safety At It's Best

When you buy a traffic drum, you will most likely be asked if you want a high (hi) density drum or a low (lo) density drum.  The difference is just the thickness of the plastic.  Some suppliers do not off this option, so you may not be asked depending on where you buy them.

Chances are it is only important to the buyer if it is important for the job.  The best way to know would be to research the requirements for the job or the project.  Checking over the requirements or calling the project designer is your best option for finding out what density your traffic drums need to be.
