Crafting Excellence:
Custom Fabricated Poly Tanks & Bulk Liquid Storage Systems

In the dynamic landscape of industrial storage and containment, the need for bespoke solutions has never been more critical. 


Our Custom Fabricated Poly Tanks & Bulk Liquid Storage systems represent the pinnacle of such tailored solutions. 


Engineered from high-quality materials like HDPE, PP-H, PVC, and PVDF, each tank is not just built but sculpted to meet the exact specifications of our clients’ storage needs.

Why Choose Custom Fabricated Tanks?

Custom fabricated tanks offer unparalleled benefits over off-the-shelf models.


They are designed with specific industrial processes in mind, factoring in the nuances of volume, space, chemical compatibility, and operational workflow. Our custom tanks ensure:


  • Optimal Space Utilisation: We design tanks to fit into your existing space, maximising storage capacity and facilitating ease of integration into your system.

  • Material Compatibility: Each substance has its own storage requirements. We select the right material to handle your substance safely, be it food products or corrosive chemicals.

  • Longevity: Our tanks are known for their robust construction and durability, resisting environmental stress cracking and impact, reducing the need for frequent replacements.

  • Compliance: With regulatory standards tightening across industries, our tanks are fabricated to meet industry-specific compliance and safety standards.

The Materials We Trust

We utilise a range of premium materials in our custom tank constructions, each offering distinct advantages:


  • HDPE: Renowned for its high strength-to-density ratio, HDPE is the go-to for impact-resistant, non-reactive storage. Its corrosion-resistant nature makes it suitable for a broad spectrum of chemicals.

  • PP-H: PP-H’s high tensile strength and resistance to a wide variety of chemical solvents and acids make it ideal for challenging industrial applications.

  • PVC: Favoured for its excellent chemical stability and fire-retardant properties, PVC is well-suited for applications that demand fire resistance and durability.

  • PVDF: With high abrasion resistance and the ability to withstand intense thermal conditions, PVDF serves high-purity applications and situations with extreme chemical exposure.

Engineering Excellence in Fabrication

Our custom tanks are the product of advanced welding and precision fabrication techniques. Each tank is constructed with a commitment to the following principles:

  • Leak-Proof Integrity: The integrity of our tanks is non-negotiable. We utilise sophisticated welding techniques that ensure a seamless, leak-proof structure.

  • Smooth Surfaces: By ensuring that the inner surfaces are smooth and non-porous, we significantly reduce the potential for bacterial growth and contamination, which is particularly crucial for food and pharmaceutical applications.

  • Custom Features: From access hatches and viewing windows to inlet and outlet configurations, we can incorporate a variety of custom features to enhance functionality and accessibility.

The Customisation Process​

Partnering with us is a journey towards achieving the perfect storage solution for your needs. Our process includes:


  1. Consultation: We begin with a thorough consultation to understand your needs, including the chemical properties of the liquids to be stored, environmental conditions, and space constraints.

  2. Design: Utilising CAD software, we design a prototype that fulfils all the discussed requirements while also advising on best practices and potential improvements.

  3. Fabrication: With the design finalised, our skilled craftsmen bring the blueprint to life, employing cutting-edge equipment and adhering to stringent quality control measures.

  4. Quality Assurance: Post-fabrication, the tank undergoes rigorous testing to ensure it meets our high standards and your expectations.

  5. Delivery & Installation: We manage the logistics of delivering the finished product to your site and can assist with the installation process to ensure optimal integration.
