The Stainless Steel Sink and Draining Board is a kitchen sink solution that integrates the main washing basin with a built-in draining board.  Model LS7848 features a compact size of 780×480×175 mm, suitable for standard countertop cutouts. Unlike ordinary single sinks, this design includes a separate draining area next to the washing area, allowing for washing, temporary placement, and natural drying on the same level, reducing water spillage on the countertop. The product uses 201 or 304 stainless steel as the base material, with an electroplated surface treatment, ensuring both corrosion resistance and visual consistency, matching the aesthetic requirements of modern kitchens for a metallic look. The top-mounted installation method creates a stable and seamless fit between the sink edge and the countertop, resulting in easy installation and convenient maintenance. The overall structure balances volume depth with compact dimensions, making it ideal for independent online retailers seeking high-efficiency, easy-to-clean, and customizable solutions.

1. Sink Body Strength

This Stainless Steel Sink and Draining Board uses an integrated stamping process, resulting in even stress distribution across the sink body.  Under a test load of 25kg, the deformation of the bottom structure is less than 0.5mm, allowing it to withstand the pressure of full water and heavy kitchen utensils for extended periods. The optimized wall thickness and structural proportions effectively reduce metal stress concentration caused by temperature changes during use, maintaining long-term stability.

2. Drainage Structure

The draining board area features a continuous embossed pattern and a slight incline, with the angle controlled within the 2–3° range. This allows water to naturally flow back into the main sink within 8 seconds, resulting in a surface residual water rate of less than 5%. This structure prevents localized water accumulation and water stains, ensuring the Stainless Steel Sink and Draining Board remains dry even in high-frequency cleaning scenarios.

3. Corrosion Resistance

The product is available in 201 and 304 stainless steel options. The 304 material shows no significant corrosion after a 72-hour salt spray test, making it suitable for humid or high-frequency use environments. Combined with electroplating surface treatment, it significantly reduces the oxidation rate, ensuring the structural and aesthetic stability of the Stainless Steel Sink and Draining Board after long-term use.

4. Surface Treatment

The electroplating layer thickness is consistently controlled within the 0.2–0.3μm range, with a surface roughness of less than Ra0.8μm. This reduces the surface area for oil and limescale adhesion by approximately 30%. The surface can be restored to its original condition with minimal effort during daily cleaning, effectively reducing the risk of scratches or discoloration during long-term use.

5. Installation Compatibility

The top-mounted structure is compatible with countertops 20–40mm thick, with a frame width controlled between 18–22mm, accommodating standard opening tolerances of ±2mm. This design reduces installation error costs, providing higher construction consistency and delivery stability for the Stainless Steel Sink and Draining Board in OEM/ODM projects.

1. Home Kitchens

In a home kitchen environment, this sink structure supports a continuous workflow of washing, temporary storage, and draining, reducing the need for additional countertop accessories. The reasonable dimensions optimize daily washing efficiency without occupying excessive space, making it suitable for home kitchens that prioritize both practicality and cleanliness.

2. Apartment Buildings

Apartment projects emphasize durability and low maintenance. This Stainless Steel Sink and Draining Board reduces countertop seams through its integrated structure, minimizing the risk of water leakage. Standardized dimensions and top-mount installation facilitate mass construction, helping developers standardize configurations and control long-term maintenance costs.

3. Light Commercial Food Preparation

In light commercial settings such as cafes and casual dining areas, this sink can be used for basic washing and temporary draining, preventing utensils from being directly placed on the countertop. The separate draining area helps maintain a clean work area and improves the continuity of the food preparation process, suitable for low to medium intensity use.

4. Rental Kitchens

Rental property kitchens experience high usage frequency and frequent user changes, requiring high product stability. This structure, with its corrosion-resistant materials and easy-to-clean surface design, reduces the appearance of aging caused by long-term use, helping landlords reduce maintenance costs during renovation cycles.

5. Engineering Customization

In engineering or custom projects, the proportion of the draining board and material configuration can be adjusted based on countertop length and usage requirements, allowing for differentiated solutions without altering the main structure. This Stainless Steel Sink and Draining Board structure is mature and easily adaptable for OEM/ODM applications.

Q: Is this sink prone to water stains or fingerprints?

A: The surface is electroplated with a uniform metallic texture, which reduces the likelihood of water stains and fingerprints. After daily use, simply rinse with water and wipe clean to maintain a clean appearance; strong corrosive cleaning agents are not needed.

Q: Does the draining board area affect the usable space of the main sink?

A: The draining board and main sink are on the same plane, with clearly defined functional areas, so it does not reduce the effective volume of the main sink. The main sink maintains its full usable space even when washing large utensils.

Q: Is the top-mount installation method suitable for different countertop materials?

A: The top-mount installation structure is well-suited for quartz, artificial stone, and solid wood composite countertops. A waterproof layer is formed using sealant during installation, effectively preventing moisture damage to the countertop edges.

Q: Is the product prone to deformation or loosening after long-term use?

A: The overall structure is a one-piece molded design, reducing structural risks associated with welding points. Under normal use conditions, it will not experience significant deformation or loosening due to alternating hot and cold water or changes in load.

Q: Do you support bulk purchasing and customized modifications?

A: The product supports OEM and ODM cooperation.  Materials, surface treatment, or local structural proportions can be adjusted according to project requirements, suitable for engineering orders and long-term stable supply needs for independent websites.
