About Rianta Door Industry Co., Ltd. - Cupboards, Doors, Gates, Grills & Windows Supplier in China

China‑based Rianta Door Industry Co., Ltd. lists eight active products across its catalogue. The company groups its offerings under the broader categories of Cupboards, Doors, Gates, Grills & Windows, Agriculture and Canned Vegetables, although the current product set focuses on door and gate hardware. Two of the listed items carry HS code 7308.30, which classifies them as iron or steel doors, and one item uses HS code 4418.20 for wooden doors. The remaining entries include furniture pieces such as LED‑bar coffee tables, which are not assigned HS codes in the supplied data. The catalogue therefore combines metal‑door hardware with a limited selection of interior furniture items.

Product Range and Specialties of Rianta Door Industry Co., Ltd.

The catalogue includes a Steel Entry Door with Decorative Glass (galvanized or stainless steel frame, tempered decorative glass) classified under HS 7308.30, a Living Room Composite Door (wood composite core with MDF/HDF surface) under HS 4418.20, Nightclub Safety Front Steel Doors (carbon or galvanized steel) also under HS 7308.30, and a Stainless Steel Gate without a listed HS code. Industry practice for steel doors of this type typically specifies a steel gauge between 1.2 mm and 2.0 mm, corrosion‑resistant coatings such as hot‑dip galvanising, and tempered safety glass meeting IC 4 (or higher) standards. Composite interior doors commonly use a high‑density fibreboard core of 20 - 30 mm thickness, an HDF surface layer of 12 mm, and hardware that complies with EN 14351‑1 for thermal performance and acoustic insulation.

Trade and Export Information - Rianta Door Industry Co., Ltd.

China is a major exporter of steel‑based doors and gates, with primary markets in the European Union, the Middle East, and Southeast Asia. HS chapter 73 (7308) covers iron or steel doors, frames and windows, while HS chapter 44 (4418) covers wooden doors; both categories usually require CE marking for the EU and may be subject to ISO 9001 quality‑management audits. Export shipments are typically packed in wooden crates or metal pallets, loaded in 20‑ft or 40‑ft containers - a 40‑ft container can hold roughly 18‑20 steel doors depending on dimensions. Common incoterms used by Chinese door manufacturers are FOB Shanghai or CIF destination port, with buyers often requesting phytosanitary or anti‑corrosion certificates as part of customs clearance.

Sourcing from Rianta Door Industry Co., Ltd. - Buyer Guidance

When sourcing from Rianta Door Industry, buyers should request material test reports confirming tensile strength and corrosion resistance for the steel frames, as well as temper‑glass certification that specifies impact resistance and light transmission values. For the composite door, a density report for the MDF/HDF surface and a fire‑rating certificate (e.g., EN 13501‑1) are typical verification documents. Buyers are advised to confirm the exact dimensions, weight, and packaging details before placing an order, negotiate a minimum order quantity (often 10‑15 units for custom‑size doors), and allow 30‑45 days lead time for production and pre‑shipment inspection.
