It is profiled as a manufacturer from its registered business scope, not from self-description. The company has been active since August 2008, holds registered capital of CNY 20 million (about US$2.8 million), reports 23 people on social-insurance payroll records, and has four affiliated companies. No administrative penalties appear on the public record.

What products does Shanghai Dazhang describe offering?

In its own marketing copy the company describes filter press and dewatering equipment (including sludge dewatering, industrial sludge, mining tailings, and shield mud), chemical conditioning and thickening equipment, precision filters, and solid-liquid separation complete engineering sets. These are company-stated descriptions and are not independently verified capabilities.

Which export markets does the company claim, and what is verified?

The company states it serves the United States, Germany, Italy, Japan, South Korea, and over 40 countries. Independent customs or shipment (bill of lading) records, export volumes, and named buyers are not yet verified.

What certifications and awards does Shanghai Dazhang claim?

ISO 9001 and CE are listed as company-stated certifications. The company also states it holds a China Well-Known Trademark. None of these items are presented as independently verified in the available data.

What should a buyer watch out for with this supplier?

The company website does not use HTTPS. Inquiries are collected via a free mailbox (QQ/163) rather than a company domain.

How does Shanghai Dazhang compare with other Water Treatment suppliers in China?

Among 40 Water Treatment suppliers in China, its registered capital is higher than 53% of peers, placing it roughly mid-range by capital size. It is older than 49% of peers, so it sits near the middle of the category for years in operation.

What's the bottom line for a buyer considering Shanghai Dazhang Environmental Protection Equipment Co., Ltd.?

This is an active Shanghai manufacturer (from registered business scope) founded in 2008, mid-range in capital and age versus other Water Treatment suppliers in China, with 23 on social-insurance records, four affiliates, and no public administrative penalties. Company-stated export markets, ISO 9001, CE, and a China Well-Known Trademark are not independently confirmed; customs records and export volumes remain not yet verified; and the site lacks HTTPS while using a free email for inquiries. Direct verification of claims is advisable before ordering.

How was this profile built — can I trust it?

Yes — it is compiled independently by our AI from dated, public evidence: business registries (via grok), an automated website audit, and Shanghai Dazhang Environmental Protection Equipment Co., Ltd.'s own site — not from anything the company submitted. Where Shanghai Dazhang Environmental Protection Equipment Co., Ltd. states something about itself, we show it beside the public record, so you are reading sourced facts, not marketing.
