Stainless Steel Sink Manufacturers

Stainless Steel Sink Manufacturer

As a Stainless Steel Sink Manufacturers, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.

Jiangsu Aozheng Metal Products Co., Ltd. is a professional stainless steel sink manufacturer and supplier based in China. With a modern production plant covering 32,000 square meters and an annual output of 8,000 tons of building materials, we produce sinks that meet the demands of commercial kitchens, healthcare facilities, and residential developments. Our range includes single-bowl, double-bowl, and multi-bowl configurations, available in various sizes and depths to suit specific project requirements.

As a factory with integrated R&D, stamping, welding, and finishing capabilities, we offer OEM/ODM services, delivering custom stainless steel sinks that align with your design and performance specifications. Our sinks are exported to over 30 countries, including the United States, Germany, Italy, and Japan, supporting global construction and renovation projects.

Why Stainless Steel Sinks?

Stainless steel remains the preferred material for sinks in demanding environments due to its combination of durability, hygiene, and cost-effectiveness. Our sinks are formed from high-quality stainless steel sheets, ensuring resistance to rust, corrosion, and staining even with constant exposure to water and cleaning agents.

• Durability: Withstands heavy daily use, impacts, and temperature variations without losing structural integrity.
• Hygiene: Non-porous surface prevents bacterial growth, making it ideal for food preparation and healthcare settings.
• Aesthetics: A sleek, reflective finish complements modern kitchen and bathroom designs.
• Affordability: Lower material and fabrication costs compared to granite or porcelain sinks.

Our Product Range and Applications

We manufacture a variety of stainless steel sinks tailored to different installation types and usage patterns. Whether you need under-mount, top-mount, or flush-mount sinks, we can produce them with precise dimensions and optional accessories such as drainboards, strainers, and overflow systems.

Materials and Specifications

We use premium stainless steel grades, typically 304 (18/8) for excellent corrosion resistance and formability, and 316 for marine or highly corrosive environments. Sheet thickness ranges from 0.8 mm to 1.5 mm, depending on the required rigidity and load capacity. Our fabrication process includes automated cutting, stamping, and welding, ensuring consistent quality and precise tolerances.

For projects requiring specific performance, we can adjust the surface finish (brushed, mirror, or matte), bowl depth, and gauge. We also provide sinks with sound-deadening pads to reduce noise and undercoating to prevent condensation.

Engineering and Customization

Our in-house R&D team works directly with your drawings or samples to develop custom sink solutions. We handle everything from material selection to prototyping and mass production. Whether you need a unique size, integrated drainboard, or special mounting clips, we can accommodate your requirements.

We also offer value engineering support, suggesting design modifications that reduce manufacturing costs without compromising performance. Our factory uses advanced CNC machining and laser processing to achieve complex shapes and high repeatability.

Quality Assurance and Testing

Quality is embedded in every step of our production. We conduct inspections after each process, and finished sinks undergo a 99.99% inspection for dimensional accuracy, surface finish, and weld integrity. Our testing laboratory is equipped with spectrometers, tension testers, and surface testers to verify material composition and mechanical properties.

We hold ISO9001 certification and have passed third-party audits such as BV, SGS, and TUV. Each batch can be supplied with material test certificates and inspection reports upon request.

Packaging and Delivery

Sinks are individually wrapped with protective film and packed in sturdy export cartons or wooden crates to prevent damage during transit. We are located near Shanghai port, ensuring efficient sea freight to global destinations. For urgent orders, air freight from Nanjing or Shanghai airports is available.

Information We Use to Configure Your Solution

To prepare an accurate quotation and production plan, we need the following details from your team:

• Overall dimensions and bowl configuration (single, double, etc.)
• Material grade (304, 316) and sheet thickness
• Surface finish and any special coating requirements
• Mounting type (under-mount, top-mount, flush)
• Accessories needed (drainage kits, faucet holes, overflow)
• Expected annual volume and target price point
• Relevant standards or certifications required

With this information, we provide a detailed proposal including technical drawings, lead times, and payment terms. Our team is available for technical consultations to ensure the final product integrates seamlessly with your project.

FAQs

What stainless steel grades do you use for sinks?

We primarily use 304 stainless steel for its excellent corrosion resistance and durability, suitable for most kitchen and bathroom environments. For coastal or chemical-heavy applications, we recommend 316 stainless steel, which offers superior resistance to chlorides and acids.

Can you produce sinks according to our custom drawings?

Yes, we specialize in OEM/ODM projects. Our engineering team reviews your drawings or samples, suggests material and production improvements, and manufactures the sinks to your exact specifications, including size, shape, and finish.

What is the minimum order quantity for custom sinks?

MOQ depends on the complexity and size of the sink. For standard models, we can accommodate small trial orders. For fully customized designs, a higher MOQ may apply to justify tooling and setup costs. Contact us with your requirements for a specific quote.

How do you ensure the quality of your stainless steel sinks?

We implement strict quality control at every production stage, from incoming material inspection to final packaging. Our lab tests chemical composition and mechanical properties, and we perform dimensional checks on each unit. Certificates are available on request.

What are your payment and delivery terms?

We typically require a 30% deposit before production and the balance against the bill of lading. Payment is usually via T/T, but L/C is acceptable. Delivery is FOB, CIF, or DDP as agreed, with sea freight from Shanghai being the most common method.

Do you provide after-sales support?

Yes, our after-sales team assists with installation guidance, maintenance advice, and any product issues. We value long-term partnerships and are committed to resolving concerns promptly.
