Lingyufab (Shanghai Lingyu Industrial Co., Ltd.) is a sheet metal fabrication and assembly manufacturer, established in 2003. Stainless steel sinks are one of the main product categories within our broader sheet metal manufacturing business. With over 20 years of experience, we handle the full production process in-house—laser cutting, CNC bending, stamping, welding, and surface treatment—which keeps quality consistent and lead times under control. We support order sizes from a single sample to 100-piece pilot runs to ongoing mass production, with current monthly output exceeding 5,000 units.

Stainless steel sinks are functional fixtures, so specifications are driven by hygiene, durability, and installation requirements.

Every kitchen or facility has its own layout and usage requirements, so Lingyufab treats each stainless steel sink as a custom project rather than a catalog item. We produce:

We also handle drainboard options, faucet hole layouts, and custom dimensions based on your drawings or samples. Our engineering team can assist with design optimization and cost reduction, and reverse engineering is available if only a physical sample exists. Prototyping starts at zero MOQ.

A stainless steel sink may look like a simple bowl, but producing one consistently involves several sheet metal processes working in sequence. Laser cutting shapes the flat blank, stamping or deep drawing forms the bowl profile, CNC bending handles secondary forming, welding joins corners and seams, and surface treatment prepares the part for its working environment. At Lingyufab, all of these steps happen under one roof rather than being handed off between vendors, which keeps tolerances tight and lead times predictable. Because fasteners and drain hardware are also made in-house, strainers and mounting accessories can be pre-installed before the sinks ship, reducing assembly work at the customer's end.

A stainless steel sink is a durable, corrosion-resistant fixture used for washing, food preparation, and equipment cleaning in kitchens, laboratories, and industrial facilities. It is typically formed from 304 or 316 stainless steel, with thickness ranging from 0.8mm to 1.5mm depending on the application. Stainless steel sinks are valued for their hygiene, resistance to stains and chemicals, and ability to withstand heavy daily use. They are available in undermount, drop-in, and commercial configurations to suit different installation and usage requirements.

Lingyufab supports 1-piece prototyping, 100-piece pilot runs, and high-volume mass production with monthly delivery exceeding 5,000 units.

Producing a stainless steel sink that fits properly and holds up in service comes down to a few practical points:

Thickness typically ranges from 0.8mm to 1.5mm depending on the application.

A sink that does not fit properly can cause installation problems and water damage, so dimensional accuracy matters.

These standards are maintained through laser cutting, stamping, CNC bending, and welding equipment, along with in-process inspection and final quality checks.

Quality control covers the full production sequence:
