Vehicle-Mounted Plastic Tanks
Overview
Vehicle-mounted plastic tanks are used for storing water, waste, fuel, chemicals, and process fluids in utes, 4×4 vehicles, trucks, trailers, and service vehicles.
We manufacture custom vehicle-mounted plastic tanks to customer drawings and specifications, supplying welded tanks designed to suit tray dimensions, chassis layouts, and mounting requirements.
Plastic tanks are commonly used in utes and 4×4 vehicles due to their corrosion resistance, lighter weight compared to steel, and ability to be fabricated to fit tight or irregular spaces.
Custom Manufactured to Suit Utes & 4x4 Setups
Vehicle tanks are rarely off-the-shelf — especially for:
-
Dual cab ute trays
-
Canopy setups
-
4×4 touring vehicles
-
Service bodies
-
Under-tray installations
-
Custom tray builds
We manufacture tanks to suit:
-
Tray dimensions and wheel arches
-
Canopy layouts
-
Chassis clearances
-
Existing mounting brackets
-
Pipework and pump locations
We work from:
-
CAD files (STEP, DWG, DXF)
-
Dimensioned sketches
-
Site measurements
-
Existing tanks supplied as samples
Tanks can be supplied as one-off builds or repeat production runs.
Typical Applications
Vehicle-mounted plastic tanks are commonly used for:
-
Water tanks for utes and 4×4 touring setups
-
Trade and service vehicle tanks
-
Spray tanks for agriculture and landscaping
-
Chemical storage tanks
-
Waste and grey water tanks
-
Mining and civil site vehicles
They are widely used across trade, agriculture, mining, off-road touring, and civil industries.
Key Performance Requirements
Vehicle tanks must account for:
-
Road vibration and corrugation (especially in 4×4 use)
-
Fluid sloshing during braking and cornering
-
Secure mounting to trays or chassis
-
Weight distribution within the vehicle
-
UV exposure for exposed installations
-
Chemical compatibility
Incorrect mounting or insufficient support is the most common cause of tank failure.

Manufacturing & Fabrication
Vehicle-mounted tanks for utes, 4×4 vehicles, trucks, and service bodies are fabricated from flat plastic sheet and assembled using controlled welding and machining processes.
Each tank is built to suit the specified dimensions, mounting method, and operating conditions.
Design & Panel Preparation
Tank panels are cut and prepared to match the required geometry and fitment constraints. This includes:
-
Precision-cut base, side, and lid panels
-
Reinforcement panels where required
-
Baffle components for surge control
-
Mounting flanges and fixing interfaces
Panels can be CNC cut to ensure accuracy and repeatability, particularly where tanks must fit tightly within tray or canopy spaces.
Plastic Welding
Structural tank fabrication is completed using plastic welding techniques suited to HDPE or polypropylene.
Welding is used for:
-
Seam joining of tank panels
-
Structural reinforcement of corners
-
Integration of internal baffles
-
Welding of threaded outlets and fittings
-
Attachment of inspection lids and access ports
Correct weld preparation and technique are critical to long-term durability, particularly in high-vibration 4×4 environments.
Internal Baffles & Reinforcement
For transport applications, internal baffles are often included to:
-
Reduce fluid surge under braking
-
Improve vehicle stability
-
Minimise tank wall flex
-
Extend service life
Reinforcement may also be added around:
-
Mounting points
-
High-stress corners
-
Large flat wall sections
Off-road and corrugated-road use typically requires additional structural consideration.
Mounting & Integration Features
Vehicle tanks can be fabricated with:
-
Integrated mounting tabs or flanges
-
Slotted mounting holes to allow chassis flex
-
Threaded inserts and welded fittings
-
Pump and hose connection points
-
Access hatches and inspection ports
Mounting design should allow for movement, expansion, and vibration without transferring stress directly into the tank body.
Quality & Fitment
Before supply, tanks are:
-
Checked against supplied dimensions
-
Inspected for weld integrity
-
Verified for fitting locations and outlets
Where required, tanks can be pressure or leak tested prior to delivery.
Production Runs
We manufacture both:
-
One-off custom tanks
-
Repeat production runs for fleet or trade use
Repeat orders can be produced from saved drawings or templates to maintain consistency across vehicles.
Design & Installation Considerations
When designing tanks for utes and 4×4 vehicles, consider:
-
Allowance for thermal expansion
-
Slotted mounting holes to accommodate chassis flex
-
Reinforcement around mounting points
-
Clearance from exhaust systems
-
Access for cleaning and inspection
-
Proper support across the tank base
Off-road conditions increase load stress, so support design is critical.
