Qinhuangdao Zhongyuan Glass Technology Engineering Co., Ltd.

Qinhuangdao Zhongyuan Glass Technology Engineering Co., Ltd. is based in Qinhuangdao, Hebei province, China and currently lists five active products. The catalogue includes a factory design service for sheet, float and patterned glass, an L&T suspended wall system, a floor‑suspended top roller machine, an annealing lehr and a batch charger. These offerings fall under the broader categories of Float Glass, Partitions, Glass Machinery, Heavy Machinery and Glass Equipment as recorded in the supplier data. The company’s product portfolio therefore spans both glass design engineering and the key processing equipment required for large‑scale glass production. All five items are presented without specific HS‑code identifiers in the supplied data.

The supplier’s catalogue lists a design service for sheet, float and patterned glass, which typically involves thicknesses from 2 mm to 12 mm, surface finish grades such as ICUMSA 45 for clear float glass, and pattern replication tolerances of ±0.2 mm. The L&T suspended wall is a partition system commonly used in commercial and industrial buildings, where glass panels are supported by a steel frame and can be fabricated to meet fire‑rating standards such as EN 13501‑1. The floor‑suspended top roller machine is a line‑side float‑glass processing unit that usually handles glass widths up to 2 m and speeds of 15 - 30 m/min, with drive motors rated between 75 kW and 150 kW. An annealing lehr is a long‑length heat‑treatment furnace that maintains a temperature gradient of 0.5 - 1 °C/m to relieve internal stresses; typical lehr lengths range from 3 m to 30 m. The batch charger supplies raw material mixes to glass furnaces and is often equipped with sealed hoppers of 2 - 10 t capacity and automated dosing controls. Industry standards for these machines include ISO 9001 quality management, CE marking for safety, and compliance with IEC 60204‑1 electrical standards.
