Engineered for absolute fluid safety and thermal dynamics, compliant with international hygienic criteria and European CE directives.
Navigating the intersection of strict biological drinking water hygiene, seismic structural mechanics, and circular metal lifecycle economics.
Water storage systems must mitigate microbiological proliferation, particularly Legionella pneumophila and biofilm colonies. Conventional concrete and composite tanks often develop micro-fissures or chemical leaching over time. CE-certified stainless steel structures provide a biochemically inert surface passivated by chromium-oxide layers, preventing heavy metal migration and securing drinking water according to the EU Drinking Water Directive (Directive 2020/2184).
Achieving CE marking requires adherence to strict structural integrity under harmonized standards such as EN 1090 (Execution of Steel Structures) and EN 1993-4-2 (Eurocode 3: Tanks). The hydrodynamic sloshing forces during seismic occurrences require precision finite-element analysis (FEA) modeling. Modular hydraulic stamped panels reduce tension stress concentrations while minimizing overall structural tare weight.
With modern green building certification bodies prioritizing materials with high circularity (such as LEED v4.1 and BREEAM), austenitic stainless steels (AISI 304/316L) offer exceptional economic advantages over a 40-year lifecycle. Completely recyclable without property degradation, our stainless steel modular vessels avoid repeated epoxy relining cycles, saving significant long-term operational expenditures.
Optimizing tank resilience based on electrochemical water chemistry, free chlorine thresholds, and ambient installation parameters.

Potable water storage tanks must conform to the Construction Products Regulation (CPR) (EU) No 305/2011 when serving as permanent building works, alongside the Pressure Equipment Directive (PED) 2014/68/EU if dynamic hydrostatic or pneumatic head pressures exceed atmospheric thresholds. Material contact safety must adhere to Directive (EU) 2020/2184.
We employ controlled Tungsten Inert Gas (TIG) welding backed by high-purity argon shielding gas. Low-carbon grade alloys (such as AISI 304L or 316L with C ≤ 0.03%) are mandatory to avoid chromium carbide precipitation along grain boundaries. Post-weld chemical pickling and passivation restore the protective chromium oxide skin.
Every production run includes EN 10204 3.1 Material Test Reports (MTR) confirming chemical breakdown and mechanical tensile yields, full liquid penetrant non-destructive testing (NDT) documentation for all weld joins, hydrostatic pressure hold certifications, and dimensional verification data sheets.
Yes. While internal braced tie rods provide structural support at minimal tare weight, our engineering team can design fully external beam-reinforced exoskeletons. This internal pillar-free design provides an entirely unhindered interior, making robotic inspection, disinfection, and maintenance straightforward.
