Worldspread Intl. (Hk) Limited supplies a door that incorporates carbon black together with zinc oxide (ZnO) or titanium dioxide (TiO2) as functional additives. The product is packed in 20 kg paper bags for the carbon‑black variant and 25 kg bags for the ZnO or TiO2 variants, as specified by the supplier. These additives are intended to enhance the door’s strength and visual properties. No dimensional data are provided in the listing.

While the exact substrate is not disclosed, doors that use carbon‑black and inorganic pigments are typically fabricated from steel or aluminium panels that receive a powder‑coated finish. Standard industry dimensions for such doors are a thickness of about 45 mm, a width of roughly 800‑900 mm and a height in the range of 1900‑2100 mm, which can be confirmed with the supplier. Typical fire‑rating for metal doors of this class is 60 minutes, and they are compatible with standard mortise lock sets. The supplier states compliance with ISO and SGS standards, although specific certificates are not attached to the listing.

The door is marketed for construction, automotive and general manufacturing applications, where the pigment additives provide corrosion resistance and aesthetic consistency. Worldspread Intl. (Hk) Limited notes that the minimum order quantity is flexible and that shipping can be organised on FOB or CIF basis. Prospective buyers should confirm payment terms and any required documentation directly with the supplier before proceeding.

Worldspread Intl. (Hk) Limited is headquartered at No.9 Zhangzhou Rd 2, Qingdao 266071, China. The supplier is listed in the imported tier and carries a trust tier of harbor, reflecting a verified profile within the platform.

The product listing does not disclose response rate, lead‑time or specific certification documents, and the reported response metrics are zero. Buyers should therefore request any needed ISO, SGS or other quality certificates directly from the company and verify the availability of the stated additives before committing to purchase.
