Plastic Tank Fabrication
Custom HDPE & Polypropylene Tanks
At Perspex Online, we specialise in custom plastic tank fabrication for industrial, commercial, and agricultural applications. Our experienced fabrication team manufactures high-quality HDPE, polypropylene, PVC and acrylic tanks designed to handle chemicals, water, and industrial liquids in demanding environments.
Plastic tanks offer excellent corrosion resistance, long service life, and strong structural performance. Whether you require a chemical storage tank, water tank, process tank, or a fully custom fabricated tank, we can manufacture a solution built to your specifications.
Using precision cutting equipment and professional plastic welding techniques, we produce durable industrial plastic tanks that are engineered to perform reliably over the long term.
Custom Plastic Tank Fabrication
Every tank we manufacture is built to suit the specific requirements of the project. Our custom plastic tank fabrication service allows you to specify the exact size, material, and configuration required for your application.
We fabricate tanks with:
-
Custom dimensions and capacities
-
Internal baffles and partitions
-
Flanges and threaded outlets
-
Inlets and outlet fittings
-
Sight tubes and level indicators
-
Access lids and inspection hatches
-
Structural reinforcement where required
Whether you require a small dosing tank or a large industrial storage tank, we can fabricate a solution designed for your system.
Applications for Plastic Tanks
Plastic tanks are used across many industries due to their durability, corrosion resistance, and cost efficiency.
Common applications include:
Water treatment tanks
Industrial process tanks
Dosing tanks
Agricultural liquid storage
Aquaculture tanks
Mixing and containment tanks
If your project requires a specialised tank design, we can fabricate a custom solution to meet your operational requirements.
Materials Used in Plastic Tank Fabrication
Selecting the correct plastic material is critical for chemical compatibility, temperature resistance, and structural strength. We fabricate tanks using a range of engineering-grade plastics.
HDPE Tanks
High Density Polyethylene (HDPE) is one of the most commonly used materials for plastic tanks. It offers excellent chemical resistance, impact strength, and durability.
HDPE tanks are commonly used for:
Water storage
Wastewater tanks
Agricultural applications
Polypropylene Tanks
Polypropylene (PP) is highly resistant to aggressive chemicals and performs well at higher temperatures compared to many other plastics.
Polypropylene tanks are often used in:
Chemical processing
Industrial manufacturing
Laboratory applications
Water treatment systems
PVC Tanks
PVC is a rigid and durable plastic that performs well in many chemical and industrial environments.
PVC tanks are commonly used in:
Chemical containment systems
Industrial processing equipment
Corrosion-resistant tank systems
Acrylic (Perspex) Tanks
Acrylic tanks are often used where visibility is required. These tanks provide excellent clarity and are commonly used for inspection tanks, aquaculture applications, and display systems.
Our team can help determine the best plastic material for your tank based on the chemicals, temperature, and operational requirements.
Precision Plastic Welding
The strength and reliability of a plastic tank depend heavily on the quality of the welds. Our tanks are fabricated using professional plastic welding techniques, ensuring strong and leak-free joints.
Our fabrication process includes:
CNC router cutting for precise panels
Professional extrusion plastic welding
Structural reinforcement where required
Pressure and leak testing
Quality inspection before delivery
This ensures each tank meets high standards for structural integrity and long-term durability.
Why Choose Plastic Tanks
Plastic tanks offer several advantages compared to traditional metal tanks.
Key benefits include:
-
Excellent corrosion resistance
-
Lightweight but structurally strong
-
Resistant to many chemicals
-
Lower maintenance requirements
-
Long service life
These advantages make plastic tanks a reliable and cost-effective solution for many industrial applications.

HDPE Water Tanks for Vehicles
Our HDPE vehicle water tanks are built for harsh Australian conditions and demanding mobile applications.
Manufactured from food-grade, UV-stabilised high-density polyethylene (HDPE), these tanks are ideal for storing and transporting water in utes, trucks, caravans, trailers, campers, service vehicles, and off-road rigs.
HDPE is the material of choice for vehicle-mounted water tanks because it’s lightweight, impact resistant, corrosion-proof, and long-lasting. Unlike metal tanks, HDPE will not rust, crack from vibration, or taint drinking water.
Why Choose HDPE Water Tanks?
Food-grade & potable safe – suitable for drinking water
UV stabilised – won’t degrade in the sun
Lightweight – reduces vehicle load and fuel use
Impact & vibration resistant – built for off-road conditions
Chemical & corrosion resistant – no rust, no contamination
Long service life – minimal maintenance required
Custom Water Tanks for Vehicles
We manufacture custom HDPE water tanks to suit your vehicle and application. Whether you need a slimline under-tray tank, a rectangular tank for a canopy, or a fully custom shape to maximise space, we can fabricate to your exact requirements.
Custom options include:
Custom sizes and capacities
Inlets, outlets, breathers, and drain ports
Threaded fittings and flanges
Internal baffles to reduce water surge
Pressure and leak testing
Common Applications
Utes and service vehicles
Caravans and motorhomes
Campers and off-road trailers
Firefighting and wash-down vehicles
Agricultural and industrial vehicles
Built for Australian Conditions
All our HDPE water tanks are fabricated locally using quality Australian materials and proven plastic welding techniques. They are designed to handle heat, vibration, rough terrain, and long-term outdoor exposure.
