The buyer needs a fabricator who builds hygiene and durability into the part, not onto it afterwards.
What food and beverage buyers need
Food and beverage processors, catering and equipment operators and plant engineers tend to be solving for the same concerns:
- hygienic, cleanable surfaces with no crevices or rough welds that can harbour residue;
- corrosion resistance to moisture, salt, acids and washdown cleaning chemicals;
- smooth, well-finished welds on food-contact and splash surfaces;
- durable equipment that holds up to daily use and frequent cleaning;
- practical layouts that suit the production flow and the cleaning routine;
- the ability to work to the food-contact and hygienic-design requirements their market sets.
The underlying need is confidence that the equipment will pass a cleaning regime and a hygiene inspection, shift after shift.
How TH Steel supports the requirement
TH Steel, established 1977 and based in Penang, provides hygienic stainless steel fabrication for food processing and beverage production. The full set of stainless steel fabrication processes is handled in-house, from cut part to finished, cleanable assembly:
- CNC laser cutting for accurate parts and clean profiles in sheet and plate.
- Plate bending and forming for tanks, hoppers, work surfaces and panels with smooth radii rather than sharp internal corners.
- Tube bending for frames, rails and pipework.
- Precision welding using TIG (GTAW), with welds ground and blended smooth for food-contact and washdown surfaces.
- Hygienic finishing and passivation to leave a smooth, cleanable surface and restore corrosion resistance after welding.
- Project assembly to deliver complete, cleanable units rather than loose parts.
Because cutting, forming, welding and finishing happen together, hygiene can be designed in, with smooth radii, crevice-free joints and a consistent cleanable finish, rather than negotiated across separate suppliers.
Typical fabricated items
Common food and beverage work includes:
- processing tables and work surfaces;
- sinks, troughs and washdown stations;
- conveyors, chutes and handling frames;
- tanks, vessels and hoppers;
- storage units, racks and trolleys;
- machine guards and equipment enclosures;
- pipework supports and structural frames;
- bespoke production equipment to drawing.
Materials, grades, finishes and standards
Grade selection follows the cleaning regime and the environment:
- 304, the general-purpose austenitic grade, suitable for many dry or low-chloride food areas.
- 316 / 316L, molybdenum-bearing, with better resistance to chlorides, salt, acids and aggressive cleaning chemicals, which makes it the common choice for washdown and wet processing. The low-carbon 316L variant is preferred for welded equipment, as it helps maintain corrosion resistance at the weld.
On hygienic work the finish is functional, not decorative. A smooth brushed No. 4 finish is common, and many hygienic specifications call for a maximum surface roughness, for example Ra ≤ 0.8 µm, which can be worked to on confirmation. Smooth, ground and blended welds, generous internal radii and post-weld passivation all help surfaces clean down properly and resist corrosion.
Why an integrated fabrication partner protects hygiene
In a food plant, hygiene is only as good as the worst detail: a rough weld, a sharp internal corner that traps residue, or a finish that will not clean. When cutting, forming, welding and finishing all happen under one roof, crevice-free joints, smooth radii and a consistent cleanable finish can be controlled across the whole piece, with fewer handoffs where a hygiene detail can slip.
For processors and plant engineers, that means one accountable partner from drawing to cleanable, installable equipment, and the option to approve a sample or first piece before the full order is made.
