A 5,000-litre vertical rectangular storage tank is one of the most common bulk liquid storage specifications in industrial, agricultural, construction, and municipal applications. Rectangular profile tanks are preferred over cylindrical in applications where space efficiency, installation on flat surfaces, or stackability is required. Typical dimensions for a 5,000-litre (5 m³) rectangular tank: 2,000mm L × 1,500mm W × 1,700mm H (approximate — dimensions vary by manufacturer and wall thickness). Wall thickness for mild steel ranges from 3mm (economy/temporary use) to 6–8mm (permanent installation). Base plate thickness is typically 4–6mm for bottom-supported configurations. Material options: - Mild steel (Q235/S235JR or Q345/S355JR): Most common, suitable for water, fuel, and non-aggressive chemicals when coated internally. Typically epoxy-lined, coal tar epoxy, or hot-dip galvanised internally. Cost-effective for large-volume procurement. - Stainless steel (AISI 304 or AISI 316L): For food-grade water, potable water, dairy, pharmaceutical, and chemical storage requiring corrosion resistance and hygiene compliance. 304 for general water/food; 316L for chloride or acidic environments. - GRP (Glass Reinforced Polyester / fibreglass): Lightweight, corrosion-resistant, suitable for chemical storage and water where steel corrosion is a concern. Common in agricultural irrigation and chemical dosing applications. - HDPE (polyethylene): Moulded or rotationally moulded, cost-effective for water and mild chemical storage, no corrosion, but lower structural strength than steel for larger volumes. Key procurement specifications: capacity (litres/m³), external dimensions, material and grade, wall thickness, internal coating or lining, inlet/outlet/drain connection sizes and positions, manhole size and type, venting, pressure rating (atmospheric or low-pressure), lifting points, and regulatory compliance (potable water approval, pressure vessel certification if applicable). For wholesale or project supply, tanks are typically quoted per unit FOB factory or CIP/DDU for large orders. Lead time: 4–8 weeks for standard configurations; 8–14 weeks for custom dimensions or special coatings.
Frequently asked questions
What internal coating is needed for a 5000 litre water storage tank?
For potable water storage in a mild steel tank, the internal coating must be food-grade and drinking water approved. Standard options are: NSF/ANSI 61 certified epoxy lining; BS 6920 approved potable water epoxy (for UK buyers); or hot-dip galvanised interior (suitable for many non-potable agricultural and industrial water uses). For non-potable water, agricultural use, or construction site water supply, a standard coal tar epoxy or solvent-based epoxy is typically sufficient.
What is the difference between Q235 and Q345 steel for storage tanks?
Q235 (yield strength 235 MPa, similar to S235JR) is the standard mild steel used for economy-range tanks. Q345 (yield strength 345 MPa, similar to S355JR) is a higher-strength low-alloy steel used for larger tanks, higher pressure ratings, or applications requiring thinner wall sections with equivalent strength. For a 5,000-litre atmospheric rectangular water tank, Q235/3–5mm wall is typically sufficient. Specify Q345 for tanks subject to hydraulic head above 5 metres, elevated loading, or thin-wall premium specification.
Can I get a custom dimension 5000 litre rectangular tank?
Yes — custom dimensions are standard for steel tank fabricators. Provide L × W × H dimensions, material grade, wall thickness, and connection layout. Most suppliers will prepare a fabrication drawing for approval before production. MOQ for custom dimensions is typically 1 unit (one-off projects) at a modest engineering fee, with competitive pricing from 5+ units. Lead time for custom: 5–10 weeks.
What certifications apply to 5000 litre storage tanks?
Atmospheric open-top water storage tanks are generally not classified as pressure vessels and do not require pressure vessel certification (PED in the EU, ASME in the US) in most jurisdictions. However, tanks for potable water require drinking water compliance (NSF 61, WRAS, BS 6920, or equivalent). For fuel storage tanks, local environmental and fire safety regulations apply. Chemical storage tanks may require chemical containment bund and material compatibility documentation.
