In the modern commercial and residential construction sectors, the choice of sanitaryware and kitchen equipment is no longer purely aesthetic. The international double stainless steel sink market has undergone a significant transformation, evolving from a simple utilitarian product to a key element of ergonomic design, hygiene compliance, and sustainable building systems. As developers, retail distributors, and hotel operators seek balance between strict budgetary frameworks and the demand for long-term product lifespans, sourcing from optimized factories with integrated ODM/OEM services has become the gold standard.
From a global macroeconomic perspective, the demand for dual-compartment stainless steel basins continues to rise. Rapid urbanization in the Asia-Pacific region, extensive renovation projects across aging housing stocks in North America, and strict commercial kitchen hygiene directives in the European Union drive steady consumption. Stainless steel remains the preferred material due to its resilience against thermal shock, chemical degradation, and physical deformation. Our 50,000 square meter production center at Henan Yigen Kitchen & Bathroom Co., Ltd. is positioned at the intersection of cost control, structural durability, and advanced design.
We strictly utilize genuine SUS304 and SUS316 austenitic stainless steel, ensuring chromium-nickel compositions that naturally resist oxidation and pitting corrosion in high-salinity environments.
All fabricated units undergo rigorous surface stress tests and weld inspection processes, adhering strictly to global standards like UPC, cUPC, and ISO 9001.
From single-unit residential apartments in dense urban hubs to high-traffic school cafeterias, our customizable profiles map to local architectural standards worldwide.
A high-quality double-bowl sink is not merely bent metal; it is the result of advanced mechanical engineering and chemical treatment. Our plant implements two primary manufacturing methodologies: high-tonnage hydraulic deep-drawing (pressed sinks) and precision handcrafted welding.
Pressed sinks are created using multi-ton hydraulic presses that stretch the steel sheet into shape. This process offers immense efficiency and pricing advantages for high-volume projects. However, to guarantee consistency in corners and walls (preventing the thinning of metal at the radius), our factory operates advanced automated progressive die stamping machines. For high-end architectural needs, our handcrafted line utilizes laser-guided cutting and argon arc welding to achieve crisp R0 or R10 radius corners, delivering maximum bowl capacity and a modern industrial look.
In addition to traditional brushed and satin finishes, our R&D division has developed an advanced Physical Vapor Deposition (PVD) coating paired with a hydrophobic nano-layer. This multi-layered barrier alters the surface energy of the sink, making it highly repellent to water, oil, and mineral scale. It also prevents typical micro-scratches caused by heavy kitchen utensils.
To address the common issue of metallic reverberation when water flows, Yigen sinks feature heavy-duty sound-dampening pads (EVA or rubber compound) covering up to 85% of the outer basin surface. This is complemented by an anti-condensation, non-toxic undercoating spray that prevents moisture buildup beneath the sink, protecting surrounding wooden cabinetry from moisture rot.
At Henan Yigen Kitchen & Bathroom Co., Ltd., we combine state-of-the-art automation with strict human inspection. Every double stainless steel sink is subjected to rigorous quality checks, ensuring uniform thickness across the bottom and sides, precise drain hole positioning, and absolute flatness of the installation rim (under-mount or drop-in).
Our integration of hardware manufacturing with custom accessories—including matching drain baskets, protective bottom grids, and integrated soap dispensers—creates a unified workspace rather than a simple basin.
A seamless, end-to-end service from design concept to mass distribution, ensuring your specifications are met with precision at every stage.

As a leading Chinese kitchen and bathroom hardware brand, we balance industrial-scale production with custom sourcing needs. We realize that importers do not just buy stainless steel panels; they require integrated solutions that solve real logistical and retail problems. Our comprehensive range of products includes handmade and pressed sinks, custom pull-out baskets, drying racks, faucets, and matching shower systems.
Through our dedicated trade and manufacturing operations, we bridge the gap between design and physical delivery. Our services feature multi-stage quality control, custom branding (laser logo engraving), bespoke packaging templates built for e-commerce shipment, and reliable delivery services across borders.
A critical step in global procurement is matching sink specifications to regional architectural standards and consumer behaviors. A double sink configured for a suburban North American family kitchen has different sizing, mounting, and thickness requirements compared to a double sink intended for a compact European urban apartment or a high-traffic kindergarten in East Asia.
Preferences: Large farmhouse apron-front double sinks, equal 50/50 split or offset 60/40 configurations. Predominantly under-mount style. Heavy reliance on thick 16-gauge SUS304 steel to handle garbage disposers.
Preferences: Reversible drop-in models with integrated drainboards. Focus on slimmer profiles, micro-radius or R0 designs, and functional integration (e.g., sliding colanders and custom prep boards).
Preferences: Highly chemical-resistant surfaces, deep-drawn bowls for splash minimization, and certified non-toxic coatings for educational and medical installations (e.g., custom cream-white or bee-yellow kindergarten styles).
By mapping out these user personas and construction mandates, our R&D team continuously delivers market-ready designs. Our catalog spans from industrial SUS304 workstation sinks to custom-colored macaron and orange models designed for designer-centric boutique apartments. This diversification allows our B2B partners to capture multiple market tiers under one shipping container load, significantly reducing overall shipping overhead.
The sanitaryware sector is evolving rapidly. Staying ahead of regulatory shifts and design trends is crucial to maintaining a strong competitive position.
Sinks are transforming into smart cleaning hubs. Future product lines are integrating touchless faucet controls, LED real-time temperature displays, and built-in ultrasonic wash chambers to clean fresh produce.
Sustainable metallurgy is the next frontier. We are actively optimizing our carbon footprint by utilizing recycled stainless steel alloys and upgrading to zero-emission PVD sputtering processes.
Traditional flat basins are giving way to tiered ledge models. By allowing custom accessories like cutting boards, colanders, and roll-up racks to slide along the rim, a double sink functions as an active food preparation station.
Key answers to technical questions concerning stainless steel sink metallurgy, production methods, and factory sourcing protocols.
SUS304 is the industry standard for residential and commercial kitchens. It contains 18% chromium and 8% nickel, providing strong resistance to rusting and chemical corrosion. SUS201 is a cheaper alternative that substitutes manganese for nickel. While it is strong, it is highly prone to surface rusting and pitting in damp or salty conditions. SUS316 contains molybdenum, offering the highest level of corrosion resistance, making it suitable for laboratory work or marine installations. Our factory strictly processes certified SUS304/SUS316 to ensure long-term product durability.
The gauge denotes the thickness of the steel sheet; a lower gauge number means thicker steel. 16 gauge (approx. 1.5mm) is standard for high-end professional kitchens, offering extreme rigidity and minimal noise. 18 gauge (approx. 1.2mm) is the standard for quality residential builds. 20 gauge (approx. 0.9mm) is commonly used in low-cost developments. Selecting a thinner gauge reduces raw material costs but increases the risk of denting and flexing under weight. We recommend a minimum of 18 gauge for long-term customer satisfaction.
Double-bowl sinks allow for multitasking: users can wash dishes in one bowl while preparing food or defrosting meat in the other. It also prevents cross-contamination in busy commercial setups. Offset configurations (60/40 splits) provide a larger bowl for cleaning wide pans, while still retaining the utility of a secondary sink.
The entire workflow spans 30 to 45 days. The design and 3D modeling stages take 5-7 days, mold manufacturing and sample preparation require 15-20 days, and performance testing along with mass production takes 15-20 days depending on the batch size. We provide weekly status reports and visual updates throughout the process.
We pack our products in drop-tested, reinforced cardboard cartons with corner guards and dense EPS foam blocks. Handcrafted sinks are nested to maximize container volume efficiency, and delicate colored/PVD finishes are wrapped in protective film to prevent abrasions. All international orders are packed in fumigated wooden pallets to ensure stable transit.
