Hygienic Design — EHEDG Doc 44:
For food, beverage and pharmaceutical clients, all structural systems are designed in accordance with EHEDG Document 44 — Hygienic Design of Buildings and Structures for the Food Industry.
This means every structural element is specified and detailed to be fully cleanable:
Closed hollow sections only (SHS/RHS/CHS) — no open profiles in food or splash zones.
Continuous welds ground flush to Ra ≤ 1.6 µm in structural zones, Ra ≤ 0.8 µm in product contact zones.
Drain holes at all low points of hollow sections.
Column bases with minimum 150mm floor clearance or fully sealed coved base.
No exposed threads in wet or product zones.
All assemblies passivated to ASTM A967 after fabrication.
A Design Compliance Statement is provided with every food-sector project for use in HACCP and food safety audits.
Quality Control:
Every stainless steel project includes six mandatory hold points:
HP-1 — PMI (XRF) grade verification of all structural members before fabrication begins.
HP-2 — Welder qualification records and WPQR review before welding commences.
HP-3 — Visual weld inspection and PT (penetrant test) on all structural connections.
HP-4 — Surface roughness (Ra) measurement on all dressed welds and handrail surfaces.
HP-5 — Full dimensional survey of assembled structure against shop drawings.
HP-6 — Pre-shipment inspection with photographic record before loading.
Mill Test Certificates (EN 10204 Type 3.1), PMI reports, weld inspection records and passivation certificates are provided as standard with every shipment.
Where Stainless Steel Structures Are Used:
Stainless steel is specified where carbon steel cannot perform — in environments combining moisture, chemicals, aggressive cleaning regimes or strict hygiene requirements. It is the material of choice across food production, aquaculture, marine and pharmaceutical construction globally.
Food and beverage processing — structural platforms, mezzanines, pipe racks and equipment support frames for meat, dairy, fish, beverage and packaged food facilities. Designed to EHEDG hygienic design principles — closed hollow sections, continuous welds ground flush, drainage at all low points, minimum 150mm clearance from floor level.
Brewery and distillery structures — mezzanine platforms over fermentation tanks, tank support frames, stair towers and CIP-compatible structural systems. SS 304 for standard brewing environments, SS 316L where caustic cleaning chemicals are applied regularly.
Aquaculture and fish processing — structural platforms, walkways, feeding system supports and onshore processing plant structures. SS 316L as minimum for coastal and marine environments, Duplex 2205 where permanent saltwater immersion or spray is present.
Marine and coastal structures — marina walkways, gangways, floating pontoon superstructures and coastal industrial platforms. Grade selection based on ISO 9223 corrosion classification of the specific site environment.
Cold storage interior structures — SS structural elements within refrigerated processing zones where carbon steel is unsuitable due to condensation cycling and aggressive washdown.
Pharmaceutical and cleanroom structures — GMP-compliant equipment support frames, access platforms and utility structures where surface finish, cleanability and material traceability are regulatory requirements.
Water and wastewater treatment — elevated walkways, pipe support structures and equipment platforms in environments containing chlorides, H₂S and treatment chemicals.
