Food factory buildings — the process sets the height, washdown sets the floor

By Johnny, export engineer at Hebei Hongji Shunda Steel Structure Engineering Co., Ltd.

Hygiene zoning decides the walls

A meat cutting room, a packing hall and a dry store are three different environments and the boundaries between them are the building. Get the zoning right and the walls are cheap; get it wrong and every wall becomes a hygiene argument.

Zoning decides more than partition: it decides where a drain can run, where a door can be, and whether a floor level can change. Those are structural and civil consequences of a hygiene drawing.

Wet end and dry end

A fruit packing house is the clearest example: the wet end washes and grades, the dry end packs. One half of the building is a wet room with falls and stainless, the other half is a dry hall that must stay dry. The frame is the same on both sides; the floor, the drainage and the wall base are not.

A bottling hall is wet, sugary and never quiet. Syrup spills, washdown water and continuous line vibration share one floor, and the building has to be detailed for all three before the line is fixed.

A frying line puts heat, steam and starch into one room. The oil film reaches every surface and the starch dust finds the roof, so the roof void is not a neutral space.

Vibration and floor tolerance

A roller floor in a flour mill is a vibration problem, not a load problem. Roller stands impose a specific frequency, and a floor that is strong enough but tuned wrong will still be rejected by the operator.

A tomato paste plant is built around one tall vessel. Evaporation, sterilisation and aseptic filling set the height, the heat and the hygiene standard at the same time, and the building follows the evaporator rather than the other way round.

Delivered record

Two of the five buildings this site publishes are food factories in Brazil: B1 at 100 m span × 98 m length, 7 m bays, 9,800 m², and B2 at 40 m span × 80 m length, 7 m bays, 3,200 m². Together 13,000 m². Neither carries an overhead crane — a crane-free frame is a different structural case from a workshop with a travelling crane on one frame line.

Sector split across the five: two food factories in Brazil, two waste treatment plants and one logistics warehouse in Burkina Faso, 19,800 m² in total. All five in one table.

Numbers behind this page

Production base 125,000 m² across six workshops; overhead cranes four at 150 t each in the West Zone from 2026; factory established 2000, current company name since 2014, exporting since 2004; quality management ISO 9001 — certificate 19822QA0131R1S, valid to January 2028. Certificate and inspection records.

Delivered spans so far 30 m to 100 m at 6 m or 7 m bay spacing, five buildings totalling 19,800 m² in Brazil and Burkina Faso. The full record, in numbers.

Notes on this sector

• Meat cutting room: hygiene zoning is the building
• Fruit packing house: wet end, dry end
• Bottling hall: wet, sugary and never quiet
• Flour mill: the roller floor is a vibration problem
• A hall sized by the machine inside it
