Premium Metallic Construction Standards
- Carbon steel (e.g., Q235B) – widely used for its exceptional strength and durability.
- Stainless steel (304 or 316) – recommended for environments demanding superior corrosion resistance.
- Aluminium alloys – preferred for marine applications due to outstanding resistance to harsh saltwater conditions.
Strict Prohibition of Incompatible Metals
- Galvanised steel – entirely banned for interior use because zinc reacts with diesel sulfides to form dangerous precipitates.
- Copper and copper alloys – avoided as they catalyse the formation of gummy residues that can clog fuel filters.
- Glass containers – strictly forbidden due to extreme fragility and high risk of catastrophic leakage.
Advanced Plastic & Composite Alternatives
- HDPE or UHMWPE – modified with conductive carbon black or internal metal components to safely dissipate static electricity.
- Fibreglass-reinforced plastic (FRP) – permitted for buried installations with a conductive inner liner and integrated grounding system to prevent charge accumulation.
Rigorous Corrosion Protection Systems
- Above‑ground tanks – require high‑quality epoxy or polyester internal coatings and exterior rust‑proofing.
- Buried tanks – demand multi‑layer composite systems (epoxy coal tar pitch or polyethylene wrapping) plus double‑walled construction for secondary containment.
