Type 3 Barricade Sheeting
There are many different brands of sheeting for traffic barricades or type 3 barricades, but 3M is probably the most common brand on type 3 barricades. There are also different grades of sheeting, with the most common being EG (Engineer Grade), DG (Diamond Grade), HI (HI intensity grade) as well as a few more.
Sheeting can add a lot of money onto the price of barricades, so it is usually recommended that you try and find the cheapest sheeting out there, and then apply your own to your barricades. Sometimes, for diamond grade, you can see a $50 increase in price between diamond and engineer grade for type 3 barricades.
