5000 Litre Rectangular Storage Tank Suppliers

5000 litre rectangular storage tanks — specifications, materials, and procurement

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.
