Custom Factory Stainless Steel Kitchen Cabinets

These cabinets are fabricated from austenitic stainless steel sheets, typically grade 304 or 316, with thicknesses ranging from 1.0 mm to 1.5 mm depending on load requirements. The material provides a passive chromium‑oxide layer that resists corrosion in humid and chemically exposed environments. Dimensional tolerances are held to ±0.5 mm for length and width, ensuring repeatable fit‑up in modular installations.

Material Specifications

Grade 304 offers good resistance to organic acids and alkaline cleaners, while grade 316 adds molybdenum for enhanced resistance to chlorides found in salt‑spray or marine atmospheres. Surface finishes include No. 4 brushed (Ra 0.4‑0.6 µm) for a uniform matte appearance and electropolished (Ra <0.2 µm) for easier cleaning. The base metal is supplied in annealed condition, yielding a minimum tensile strength of 515 MPa and a yield strength of 205 MPa.

Design & Customization

Cabinets are built to project‑specific dimensions, with standard module widths of 300 mm, 400 mm, 500 mm and 600 mm, and heights adjustable in 50 mm increments. Door styles overlay, inset, or frameless, each affecting the required clearance and hinge load. Interior accessories such as adjustable shelves, pull‑out trays, and integrated lighting are designed to support loads up to 150 kg per shelf when reinforced with stainless steel brackets.

• Custom cut‑outs for sinks, appliances, and service conduits.
• Optional toe‑kick heights ranging from 100 mm to 150 mm.
• Choice of hinge types: concealed European, butt, or pivot, each rated for 30 kg door weight.
• Edge treatments: square, rounded (2 mm radius), or beveled for safety.

Manufacturing Process

Blank sheets are laser‑cut to ±0.1 mm positional accuracy, minimizing heat‑affected zones. Edges are deburred using vibratory finishing to achieve a uniform surface roughness. Joints are welded with TIG (GTAW) using ER308L filler for grade 304 and ER316L for grade 316, followed by passivation in a nitric‑acid bath to restore the protective oxide layer. Final assembly incorporates mechanical fasteners where disassembly is required for maintenance.

Quality Control

Each cabinet undergoes dimensional verification using a coordinate‑measuring machine (CMM) with a repeatability of ±0.02 mm. Surface finish is assessed with a profilometer to confirm Ra values within the specified range. Corrosion resistance is validated by salt‑spray testing (ASTM B117) for 500 hours, after which any signs of red rust are recorded and rejected. Visual inspection checks for weld uniformity, scratches, and coating continuity under 10× magnification.

Applications

In food‑processing plants, the cabinets withstand frequent wash‑downs with hot water and alkaline detergents, maintaining hygiene standards without harboring bacteria. Pharmaceutical facilities benefit from the non‑porous surface that resists solvent‑based cleaning agents and facilitates sterilization cycles. Laboratories choose stainless steel for its resistance to chemical spills and its ability to support heavy equipment without deformation.

• Walk‑in coolers and freezers where thermal conductivity must be low.
• Clean‑room environments requiring ISO Class 5‑7 compliance.
• Commercial kitchens subject to high humidity and frequent impact.
• Marine galleys exposed to salt‑laden air.
