Fire Apparatus Tanks
Fiberglass or Polypropylene? We
make both!

Custom Composites has been in business
for 30 years and serving the needs of fire
apparatus manufacturers for the last 20
years. We offer fiberglass and
polypropylene tanks in standard
configurations or custom. We are centrally
located in the United States, which saves
you money on shipping and you get your
tanks faster. The Custom Composites staff
is highly experienced and motivated to
build your tank to the highest standards.
Our tanks are, for the most part, custom
made to the exact specifications of our
clients, not taken off the shelf for you to
make do with. A custom tank without the
custom price. You supply us with your
drawings and/or specifications, so you get
exactly what you want. If you're not quite
sure what you need, our professional
design team will assist you. However, we do
offer some standard tanks for you to
choose from to simplify the buying process.

Our fiberglass tanks come with a high gloss
red gelcoat and polypropylene tanks come
in standard 1/2" black. Other colors
available if needed. We have an excellent
warranty and technicians that can modify
your tank in the field, should you need it. So
whether it's a 50 gallon slip-in unit, a 3,000
gallon T-tank, or anything in between, give
us a call. Let us be your "ONE STOP SHOP"
for fire apparatus tanks.

95% Of Our Polypropylene Tanks Are Custom At A Standard Price.  
Fully Extrusion Welded Inside and Out, No Hand Welding Here!  
Which is stronger 1/4" thick weld or 1/2" thick weld?  We agree, so
6 years ago we decided to use the 1/2" thick weld exclusively.
If you work for a fire department and get a price from one of our distributors first, then we cannot bid your tank, this keeps us from competing against our distributors.
We have one extra 500 gallon tank ready
for delivery $3364.00, this includes the 10
gallon foam cell and pump platform sheet.
