The RUST Road Signs fall into the component category of items. These components are used in the creation of multi-tiered items, as well as recycle fodder for players to obtain game building and crafting resources as well as Scrap.
Road signs are lootable from an assortment of low-to-high tier crates and barrels, as well as being dropped by most scientist types. RUST players can also find roadsigns on roadsides by destroying signage.
While useful, road signs are on the higher end of availability compared to how many blueprints utilize them. Their primary function is in the crafting of the Roadsign armor set, and to that end, very few are actually required to craft the armor.
With regards to their recycling yield, they produce a very high amount of scrap and high quality metal for the amount of road signs that players find. Due to the exclusive nature of their use, they are more than likely going to be recycled in excess. While it is advised to keep a good deal of these on hand to craft new kits when applicable, more than a few stacks are mostly redundant. The scrap and high quality metal are of far more use.
