Q Most manufacturers offer a one-size-fits-all customization approach, making it difficult to meet non-standard or custom‑specification requirements.

A Equipped with end-to-end, scenario‑specific customization capabilities, we collaborate closely with architects and curtain‑wall contractors to meet a diverse array of bespoke requirements—ranging from complex geometries and oversized dimensions to specialized performance specifications. Our solutions seamlessly translate creative curtain‑wall concepts into reality, unbound by standard specifications, thereby fully realizing architectural visions.

Q Conventional glass typically comes with a short warranty, its seals tend to age quickly, and it is prone to fogging and water leakage.

A Backed by an official 25-year warranty, this product features a high-performance, long-lasting sealing system that slows the aging of the insulating glass sealant, effectively preventing common issues such as fogging and water ingress. With a designed service life of up to 50 years, it is ideally suited for long-term operational environments like commercial and public buildings.

Q Small and medium-sized processing plants have limited production capacity and weak quality control, making it difficult to ensure timely delivery of large orders.

A The company has invested RMB 500 million in fixed assets, establishing an intelligent, large-scale production base capable of producing up to 5 million square meters of architectural glass annually. Equipped with a full suite of state-of-the-art processing equipment and standardized quality-control procedures, the company can reliably undertake large-scale curtain-wall projects, ensure timely delivery of high-volume orders, and deliver on both quality and lead-time commitments.

Q Ordinary tempered glass exhibits insufficient flatness, causing image distortion in curtain walls and resulting in a poor visual effect on the building façade.

A The tempered glass temperature-control system and forming process have been upgraded, with rigorous control over panel curvature, reducing the rate of poor flatness to below 1.5‰. The finished glass panels exhibit exceptional flatness and clarity, ensuring that, once the curtain wall is installed, images are rendered naturally without distortion—fully safeguarding the visual integrity of high-end commercial building facades and meeting the stringent design requirements of premium curtain-wall projects.

Q Ordinary tempered glass has a relatively high spontaneous breakage rate, posing safety risks and incurring high maintenance costs over time.

A Leveraging a mature, precision‑driven production control system, we have precisely optimized raw material selection and tempering processes, reducing the glass spontaneous breakage rate from the industry‑standard 3‰ to 0.1‰. This significantly lowers the likelihood of spontaneous glass failure, mitigates the risk of falling debris at height, and substantially cuts down on the additional costs associated with post‑project repairs and replacements.

Entering Huadong Coating

For many years, the company has produced and sold over 5 million square meters of various glass deep processing products annually. The product sales area covers many large and medium-sized cities in China, and is also exported to more than ten countries and regions such as Europe, America, and Southeast Asia. In May 2024, the company's intelligent digital production line was officially put into operation, and the configuration scale and processing strength of the "three cutting four grinding two steel connection TPS/4SG mid air line" are at the forefront of the intelligent connection upgrade and transformation of domestic glass deep processing enterprises. After more than 30 years of development, the company has become one of the strongest comprehensive supporting enterprises in the glass deep processing industry in Jiangsu Province. Never forget the original intention and forge ahead. The company will always adhere to the business philosophy of "quality first, service first", constantly explore and innovate, keep pace with the times, and contribute the strength that a wholly-owned state-owned enterprise should have to the high-quality development of the industry.
