Custom Chemical Storage Tanks Built to Resist Corrosion
Storing chemicals safely means matching the tank material to what is actually going inside it, since the wrong plastic can degrade, swell, or fail against certain acids, alkalis, or solvents over time. A custom-welded chemical storage tank, built from a chemically resistant sheet material, avoids the corrosion problems that steel and many metal tanks face when exposed to aggressive chemicals long-term.
Custom fabrication also means the tank fits the actual space available, whether that is a tight bunded area, a specific truck deck, or an odd-shaped corner of a chemical store, rather than forcing a standard round tank into a space it was never designed for.
Choosing HDPE, Polypropylene, or PVC for Chemical Compatibility
HDPE sheet is the most widely specified material for chemical storage tanks, offering broad chemical resistance across a wide range of common industrial and agricultural chemicals, plus straightforward welding for a fully sealed tank. Polypropylene has an even higher resistance to certain aggressive chemicals and higher-temperature applications, making it the preferred choice for some acids and solvents where HDPE is not rated.
Rigid PVC sheet is a further option for tanks handling specific chemical groups where PVC's resistance profile is a good match, and is often used for smaller ancillary tanks and fittings rather than large primary storage vessels.
Baffles, Fittings, and Tank Accessories
Internal baffles can be welded into larger tanks to reduce liquid surge during transport or filling, an important safety feature for tanks mounted on vehicles or subject to movement. Bunded double-wall construction is available for tanks storing chemicals that require secondary containment under Australian storage regulations.
Fittings including bulkhead outlets, level gauges, vents, and lid access hatches are welded in during fabrication to match your pumping and monitoring equipment.
Transport and IBC Replacement Tanks
For sites that need to move chemicals between locations, a custom-welded transport tank built to fit a specific vehicle tray or trailer frame eliminates the strapping and securing problems that come with using round tanks on flat decks. Square or rectangular tanks use deck space more efficiently and can be designed with integrated tie-down points and baffles to prevent surge during transit.
We also fabricate replacement tanks for sites looking to move away from IBCs (intermediate bulk containers) to a permanently installed, purpose-built storage solution with proper fittings, bunding, and site-specific dimensions.
Sizing and Siting a Chemical Storage Tank
Tank sizing should account for the chemical's density, the required storage volume, and any regulatory bunding or setback requirements for your site or industry. We work from your specifications to confirm the right material, wall thickness, and fitting layout before fabrication begins.
Provide the chemical to be stored, required volume, and site constraints, and we will recommend a material and configuration suited to safe, compliant long-term storage.
