Differences Between Fiberglass & Roto Molded Poly Dock Box Products

Many of our customers ask concerning which product should they choose, roto molded poly or fiberglass? Here are the primary differences:

The Look & Finish:

  • Fiberglass offers a glossy sheen surface that is very attractive and  has a high end appeal
  • Ploy Titan STOR boxes offer a matte finish that is very attractive but not shiny or glossy

The Durability:

  • Titan STOR is your best choice when it comes to durability; if you are looking for a box that will last through hail storms, travel, abuse and just about anything you can imagine, the Titan STOR is the box you need.
  • Fiberglass will last forever, but unlike poly there is a need to keep it protected from harsh treatment. Fibergalss can crack (just like a fiberglass boat hull) when abused.

The longevity.

  • Prettymuch the same.  Fiberglass and poly are both going to last a lifetime if treated properly (don’t run over them with a tractor my friends)

The price

  • About the same.  There is not a lot of difference when it comes to the cost of boxes.

Fiberglass advantages

  • We offer many more styles and designs of fiberglass boxes because it costs much less to set up a new fiberglass design.
  • Rotomolding is much more costly to set up and because of that there are fewer styles to choose from currently.

The advantages of poly roto-molded products are mainly held in the incredible durable over fiberglass.  Fiberglass holds up to the elements extremely well, however when compared to poly, fiberglass is just too brittle.  That’s where poly chins.

Try this.  Get a hammer and smack the side of a fiberglass boat hall.  OK, don’t ACTUALLY do that… but you get the idea.  Then, take that hammer and hit a plastic tupperware bowl or any similar plastic product.  Now, you can understand the difference.
