How to determine whether the quality of stainless steel wardrobes is qualified?

To determine whether the quality of a stainless steel wardrobe is qualified, a comprehensive evaluation needs to be conducted from multiple aspects such as material, process, and accessories. The following are specific criteria and methods for judgment:

Material Selection

Stainless steel type: 304 stainless steel is preferred as it has a high chromium content (usually above 18%), can form a dense oxide film, and has excellent rust and corrosion resistance. For medical environments that require high cleanliness, 316L stainless steel can be considered as it has added molybdenum element, which enhances its resistance to chloride corrosion.

Thickness standard:

Economy type: 0.6-0.8mm (suitable for low-frequency usage scenarios)

Standard type: 0.9-1.2mm (meets daily needs, most families choose)

Heavy duty: 1.2-1.5mm (commercial or load-bearing scenarios)

According to the standard, the thickness of the countertop support part of high-quality stainless steel cabinets should not be less than 1.0mm.

Process and Structure

Welding process: The cabinet should be resistance welded to ensure that there are no exposed welding points, and the welds should be tight and seamless.

Surface treatment: The surface should be smooth and free of burrs, and the corrosion resistance can be verified through salt spray testing (such as ≥ 500 hours).

Sealing: The gap between the cabinet door and the cabinet body should be controlled at 1.0-1.5mm, and it should have magnetic suction function to prevent dust from entering.

Accessory quality

Hinge: It needs to pass durability testing (such as opening and closing ≥ 40000 times) and have rust prevention performance (such as appearance rating ≥ 7 level after 72 hours of salt spray test).

Guide rail: It is recommended to use a steel three section silent guide rail, with a single drawer bearing capacity of ≥ 30kg.

Handle: Hidden rolled edge handle is safer and requires passing the acetate salt spray test (≥ 200 hours).

Environmental Protection and Safety

Environmental certification: Check if there is a national environmental certificate.

Odor detection: Open the cabinet door and drawer. If there is a strong irritant odor, it may exceed the formaldehyde limit and should not be purchased.

Functional Testing

Opening and closing experience: Cabinet doors and drawers should be flexible to push and pull without any jamming.

Load bearing capacity: The load-bearing capacity of the movable layer board should be ≥ 30kg to ensure stability.

Through the above standards, the qualification of stainless steel wardrobes can be comprehensively evaluated. If you need further information on material differentiation or testing methods:
