Frequently Asked Questions
What is a self-bunded fuel tank?
A self-bunded fuel tank is essentially a tank within a tank. The inner tank serves as the primary storage, while the outer layer acts as a protective shell, capturing any leaks or spills. This dual-layered design makes them ideal for ensuring safety and compliance with environmental regulations.
What is the difference between a self-bunded and non-bunded tank?
The key difference lies in the construction. A self-bunded tank has dual layers, providing an in-built containment solution for leaks. In contrast, non-bunded tanks require a separate secondary containment, such as a drip tray or bund, to catch spills, making them less integrated and potentially more hazardous.
What materials are your self-bunded fuel tanks made from?
Our self-bunded fuel tanks are primarily made from high-grade steel, known for its durability and strength. This material ensures a long service life and resistance to the harsh Australian climate and industrial conditions.
Do you offer different types of self-bunded fuel tanks?
Yes, we offer a variety of self-bunded tanks designed to store different fuels, including diesel, petrol, aviation fuels, oils and other specialised fuels. Each tank is tailored to meet specific industry standards and client requirements.
What is the cost of a self-bunded fuel tank?
The cost of self-bunded fuel tanks varies based on capacity, features, and specific configurations required for your operations. For accurate pricing, please contact us directly to discuss your specific needs and obtain a detailed quote.
How long does it take to deliver a self-bunded fuel tank?
Delivery times for our self-bunded fuel tanks depend on your location and the tank specifications. Generally, we aim to complete delivery within 4 to 6 weeks from order confirmation. For urgent requirements, please discuss your needs with us for faster processing.
Are self-bunded fuel tanks better for the environment?
Yes, self-bunded fuel tanks are better for the environment due to their double-wall design, which significantly minimises the risk of fuel leaks and spills. This containment system helps protect the surrounding environment from potential contamination, supporting compliance with stringent environmental regulations.
