Contact UsStandard single-ply stainless steel cookware suffers from uneven heat distribution and localized scorching (hot spots), whereas pure aluminum cookware lacks structural rigidity and induction compatibility. Our factory solves this material conflict through high-pressure thermo-molecular bonding of three distinct metal alloys into a unified cladding matrix.
The interior vessel surface is composed of high-grade 18/10 Chromium-Nickel stainless steel. This alloy exhibits superior resistance to acid, alkali, and salt corrosion from food preparation. It creates an inert cooking surface that prevents metallic leaching and maintains hygienic standards under continuous commercial utilization.
Encapsulated completely between the steel layers is an ultra-conductive aluminum core. Aluminum possesses a thermal conductivity rating roughly nine times greater than stainless steel. By running the core continuously from the pot base up through the sidewalls, liquid contents heat 64% faster with uniform wall-to-wall temperature equilibrium.
The exterior layer utilizes a high-permeability magnetic ferritic stainless steel (18/0). This ensures 100% efficiency across high-wattage induction hobs while maintaining high resistance to exterior denting, scratching, and atmospheric oxidation in industrial dishwashing environments.

Partnering directly with a source manufacturer provides global distributors, brand owners, and hospitality suppliers with competitive unit economics, flexible branding options, and stringent batch quality control.
Equipped with 800-ton to 1200-ton hydraulic deep-drawing presses, our facility produces seamless stock pot bodies ranging from 4 Liters up to 100+ Liters in commercial capacity. We support custom height-to-diameter aspect ratios to accommodate unique kitchen footprints and specialized boiling requirements.
We provide comprehensive private label customization including laser-etched internal volumetric scale lines, custom-stamped bottom logos, specialized mirror or satin/brushed exterior polishes, and custom physical vapor deposition (PVD) color accents on handles and lids.
Every production batch undergoes destructive and non-destructive quality testing: ultrasonic wall thickness measurement, 5% salt spray testing (ASTM B117) for corrosion verification, handle torque/tensile load testing, and planarity testing to prevent thermal warping on induction cooktops.
As commercial catering sectors modernize and environmental regulations shift globally, B2B buyers must align their product sourcing with emerging technology and sustainability demands.
With commercial kitchens worldwide transitioning from open gas burners to high-wattage induction suites to reduce kitchen ambient temperature and HVAC energy bills, future stock pots demand thicker ferromagnetic outer plates. Our 430-grade clad bases are engineered for instant magnetic coupling, reducing boiling times by up to 22% compared to standard disc bases.
Traditional through-rivets create internal food trap crevices that harbor bacterial growth and require intensive labor to sanitize in commercial kitchens. The industry is rapidly pivoting toward projection-welded hollow handles. Our automated welding lines ensure joint shear strength exceeding 600 kg without breaking the interior SS304 smooth wall finish.
Global ESG mandates require enterprise procurement teams to trace raw material origins. Our tri-ply stainless steel stock pots are crafted from 100% infinitely recyclable stainless steel scrap metal and virgin aluminum alloys, compliant with RoHS, REACH, and European circular economy directives.
Clear answers regarding custom tooling, minimum order quantities, compliance certification, and international supply chain logistics.
Our standard MOQ for full custom OEM production (custom dimensions, thickness, and brand stamping) is 500 units per size SKU. For standard catalog sizes featuring custom laser-etched logos and customized packaging boxes, we offer lower minimums starting at 200 units to support expanding brand lines.
We utilize cold-roll bonding under ultra-high pressure followed by precision atmosphere-controlled annealing. This creates a solid-state metallic bond between the SS304, Aluminum, and SS430 layers. Our products undergo rigorous thermal shock testing (heated to 300°C and immediately quenched in cold water for 50 consecutive cycles) with zero delamination.
Our factory operates under ISO 9001:2015 quality management systems and holds BSCI ethical audit approval. All cookware products meet or exceed FDA 21 CFR 175.300, EU Regulation (EC) No 1935/2004, LFGB, and DGCCRF food-contact safety parameters.
Yes. We supply fully functional prototype samples, including custom laser logos and handle samples, within 7 to 10 working days. Sample tooling fees are fully credited against the invoice total upon execution of the official high-volume purchase order.
Standard production turnarounds are 30 to 45 calendar days following artwork confirmation and deposit receipt. For recurring OEM orders with reserved material stock agreements, lead times can be compressed to 20 days.
We offer solid cast SS304 stay-cool handles, ergonomic tubular handles, and silicone-overmolded heat-resistant grips. Lids can be matched with solid tri-ply stainless steel covers, domed self-basting lids, or tempered glass lids with steam vents depending on market positioning.
