Yes. We supply technical drawings, material specifications, and finish documentation suitable for architects, interior designers, and project developers working on specification submissions.

Our products are engineered to meet the standards applying in our principal export markets. Certification requirements differ by market and by product — gas appliances, for example, carry specific certification obligations — so please confirm the requirements for your destination at the time of enquiry, and we will advise on what documentation and testing can be provided.

JIUNAI holds a High-tech Enterprise Certificate and utility model patents, and is a vice-president member of the Guangdong Cabinet Industry Association. The brand has been recognised as one of the Top 10 Brands of Stainless Steel Cabinets in China for three consecutive years, and our products are supported by authoritative third-party testing and certification.

Spare parts — including hinges, runners, and replacement doors or drawer fronts — can be supplied on request. Lead time for spare parts is shorter than for a full production order, but please allow time for manufacture to the original specification.

Contact our export team with your order reference, a description of the issue, and photographs where relevant. We will assess the matter and respond with a proposed resolution.

The warranty covers manufacturing defects in the cabinet structure and specified components when the product is used for its intended purpose and maintained in accordance with our care guidance. It does not cover damage arising from misuse, accidental impact, improper installation, unauthorised modification, exposure to chemicals outside normal cleaning agents, or normal wear and tear. The full terms are set out in the warranty statement supplied with the order.

JIUNAI stainless steel cabinets carry a warranty of up to 10 years, subject to the terms applicable to the product and the destination market. Warranty terms are confirmed in the order documentation. Please refer to the warranty statement issued with your order for the specific coverage applicable to your purchase.

Yes. Doors, drawers, hinges, and runners can be replaced individually. Because we manufacture to order, we recommend retaining your final workshop drawings so that any future replacement matches the original specification precisely.

Routine care is simple. Wipe surfaces with a soft cloth and a mild neutral detergent, then dry with a clean cloth. For fingerprint-resistant and nano-coated finishes, a damp microfibre cloth is normally sufficient. In coastal and outdoor applications, rinse with fresh water periodically to remove salt deposits.

Avoid steel wool, abrasive pads, and strong acidic or chlorinated cleaners. These can dull the surface and attack the passive oxide layer that gives stainless steel its corrosion resistance.

Yes. Each order is supplied with installation guidance, and online technical support is available during installation. For projects requiring it, we can provide drawings and documentation suitable for your installation team.
