Import Door — Buy in Bulk from Supplier in China

The door supplied by Zhejiang Zhongheng Industry & Trade Company is presented as a premium entry solution for both residential and commercial buildings. Constructed from high‑grade steel, the panel includes a polyurethane foam core that enhances thermal insulation and reduces sound transmission. The design offers multiple surface finishes, such as anodised aluminium or wood veneer, and can be customised to fit a broad selection of openings. Weather‑resistant treatment ensures durability in both indoor and outdoor environments.

In the door industry, mild steel of typical grade Q235 is commonly used for the outer skin, with a panel thickness around 40 mm to balance strength and weight. A 30‑minute fire resistance rating is standard for non‑fire‑rated doors, while higher ratings are available on request. Typical dimensions extend to 2800 mm × 850 mm, and the weight of a standard size panel is roughly 70 kg. Multi‑point locking systems are frequently specified to meet security requirements.

Architects, contractors and property owners select these doors for their aesthetic flexibility and reliable insulation performance. The supplier offers flexible minimum order quantities and ships using FOB or CIF terms from Chinese ports, with packaging designed for bulk transport. ISO 9001 and CE certifications are listed, but buyers should obtain the most recent certification copies before finalising the purchase.

Zhejiang Zhongheng Industry & Trade Company is an imported supplier located at 65 Yonghua Road, Yongkang, China (postal code 321300). The firm carries a harbor trust tier, indicating verified trade credentials, but its recorded response rate is 0 % with no recent replies, suggesting limited communication activity on the platform. The listed address provides a verifiable Chinese business location for potential on‑site visits.

The catalogue highlights a premium door built from high‑grade steel with optional finishes and a foam‑filled core for insulation. While the listing mentions ISO and CE certifications, it does not disclose details about production capacity, workforce size or past client projects. Buyers should therefore request additional information on manufacturing processes and quality management to assess suitability.
