Category 5 - EPS Blanks
-
Category 5 EPS is the premier supplier for EPS surfboard cores on the East Coast. We incorporate only the industry's highest quality materials. EPS Foam has recently replaced outdated old style Styrofoam making for a highly water resistant blank. EPS, laminated with space age traditional fiberglass cloths and epoxy, is safer for the builder, better for the environment, produces boards that are lighter, more ding resistant and less likely to break than boards using old style surfboard materials.
-
EPS production allows for significant customization by the builder. Virtually any style, rocker or size blank can be recreated using EPS. Proprietary rocker templates can be created from proven designs that result in minimal foiling and increase product consistency.
-
We are among the few suppliers who use small "c" bead foam. The smaller beads are resistant to chipping, are shaper friendly and have exceptional water resistance. It costs us more, while we keep our prices low -- don't be fooled by cheap imitations, ask for our technical sheet on our foam and the competition’s foam for details.
Our entire listing of available EPS rockers and purchase options are below.
***New Rockers are added frequently, if you are a new or returning customer please be sure to check back often for any updates!

Stringer Options:
- We can do 1/8" PVC to 8' and Wood to 10' plus, also 1/4" wood and other marine ply on request.
- Most suppliers glue up their pvc stringered blanks with water based adhesives -- we don't! Our process does not introduce damp water laden glue inside the blank. We have consulted engineers in the adhesives industry who confirm water based adhesives in eps/pvc applications introduce water that may never dry completely, leaving water in your production product as delivered to the customer!
Custom Rockers:
- We will make templates and blanks to manufacturer's specifications. A primary advantage to EPS is that the shaper can have his proven rockers built to his specifications. Provide whatever information you have, offsets, tracings or even a finished board, and we will build a blank to match.
OTHER FAQ:
What do I need to get a custom rocker built?
I will build your blanks to your specifications using your offsets, tracings or even a finished board. One method is to shape your rocker into a stock blank that I provide you. We then cut out the stringer and that becomes the master for your templates. This will be a proprietary rocker template and only provided to your operation. (additional cost of $25 for existing rocker and $45 for tracings - to cover materials and labor, one time charge.)
What about "rocker adjustments?"
Adjustments are made in the template. Unlike adjustments to polyurethane blanks, EPS does not bend the foam and distort the deck. The deck is redrawn for smooth entry and exit through the change.
What about custom stingers?
Many stringer materials come in 8' lengths, such as PVC and other marine ply. Blanks under 8' have a wide variety of stringer options and placements, blanks over 8' will usually come with 1/8" to 1/4" basswood. Any number of options are available such as stringerless or additional placement of custom stingers.
