Custom Plastic Tanks
Overview
Plastic tanks are used for fluid storage and containment across automotive, marine, industrial, and commercial applications. Compared to metal, plastic tanks offer corrosion resistance, chemical compatibility, reduced weight, and flexible fabrication options.
We manufacture custom plastic tanks to customer drawings and specifications, supplying welded and fabricated tanks ready for installation.
Custom Fabricated to Your Drawings
Plastic tanks are almost always application-specific. Size, shape, fittings, and material selection depend on the fluid, environment, and installation constraints.
We manufacture tanks from:
CAD drawings (STEP, DWG, DXF)
Dimensioned sketches or PDFs
Existing tanks supplied as samples
Measured replacement tanks
Tanks can be supplied as one-off fabrications or repeat production runs.
Typical Tank Applications
Custom plastic tanks are commonly used for:
Vehicle-mounted tanks
Marine tanks
Chemical storage tanks
Water and wastewater tanks
Process and equipment tanks
Applications range from small enclosures to large fabricated vessels.
Key Performance Requirements
Tank design and material selection depend on:
Type of fluid being stored
Chemical compatibility
Operating temperature
Mechanical loads and mounting method
UV exposure (indoor vs outdoor use)
Material selection is critical for long-term performance and safety.
Recommended Materials for Plastic Water Tanks
HDPE (High Density Polyethylene)
Most common tank material
- Excellent chemical resistance
- Weldable and impact resistant
- Suitable for water, fuel, and many chemicals
Typical uses
- Vehicle tanks
- Water tanks
- Industrial fluid storage
Higher temperature and chemical resistance:
- Excellent resistance to acids and chemicals
- Good weldability
- Higher temperature performance than HDPE
Typical uses:
- Chemical process tanks
- Industrial containmen
Rigid chemical-resistant option
- Good chemical resistance
- Easy to fabricate for rigid tank designs
- Not suitable for impact-heavy applications
Typical uses
- Chemical storage
- Fixed installations

Manufacturing & Fabrication Services
Plastic tanks are fully fabricated assemblies, not flat-sheet products.
Plastic Welding
Plastic welding is used to fabricate tanks from flat sheet into sealed vessels.
Used for
Panel joining
Seam welding
Fitting and outlet integration
Structural reinforcement
CNC Machining
CNC machining is used for precision-cut panels, baffles, flanges, and openings.
Used for
Tank panels and lids
Flange openings
Internal baffles
Mounting features
Installation Considerations
When designing plastic tanks, consider:
Allowance for thermal expansion
Support and mounting points
Venting and access openings
Cleaning and inspection access
Tank performance depends on design, material, and fabrication quality.
