Three product families, from the product catalogue.
Stainless Steel Fasteners
U-bolts, hex bolts, socket head cap screws, flange bolts, hex nuts, spring washers, flat washers and expansion bolts in stainless steel. The product album shows multiple sizes; material grades, standards (DIN, ASTM, JIS, GB) and size ranges are not stated — ask.
Stainless Steel Flanges
Weld neck flanges, slip-on (flat welding) flanges, blind flanges, socket weld flanges, flange caps, sight glass flanges and non-standard flanges. Pressure classes and facing types are not stated — ask. Non-standard (non-catalogue) flanges suggest the workshop can work to drawings.

What the registry confirms, and what stays open.
What the Scope Says
The registered scope, read on 2026-09-28 and quoted without change, is 不锈钢制品制造（依法须经批准的项目，经相关部门批准后方可开展经营活动） (stainless steel products manufacturing; projects requiring approval to be conducted after approval by relevant authorities). Manufacturing is in scope.
Import & Export: Not in the Scope Wording
The registered scope wording does not include import and export. Ask for the customs consignor / consignee registration and a recent export declaration before the first shipment. Many small manufacturers in this cluster export through a trading company — confirm the arrangement.
Capital and Ownership
Registered capital RMB 2,000,000, of which RMB 1,000,000 paid-in (registry). Company type is a limited liability company with a single natural-person investor (自然人独资). This is a micro enterprise by official classification. The sole investor is not named on this page.
Zero Court Records
The risk check on 2026-09-28 returned zero own-risk, zero related-risk and zero historical entries. This is a clean record. Standard practice: agree payment terms and inspection rights in writing regardless.
Insured Employees: Zero on Record
The registry shows zero insured employees (社保参保人数 0). This is common among small workshops in this cluster and does not by itself mean the company has no workers, but it is a data point a buyer should note. Ask about the actual workforce and workshop capacity during a site visit.
What was checked — and what the check found.
The registry facts on this page — status, capital, paid-in, company type, scope wording, insured employees and the zero court-record count — come from a first-hand registry and risk read by CMH on 2026-09-28; the credit code’s check digit was recomputed by CMH. Product families and types are identified from a 24-page product album and three product-overview images supplied by the applicant. No specification sheet, material certificate, test report, ISO certificate or export document has been sighted. The company has no English-language website on record and has not been visited by CMH. This page is updated when documents arrive.

Frequently Asked Questions
What does Zhengshun make?
Stainless steel fasteners (U-bolts, hex bolts, socket head cap screws, flange bolts, hex nuts, washers, expansion bolts), flanges (weld neck, slip-on, blind, socket weld, sight glass, non-standard) and pipe fittings (elbows, tees, crosses, reducers, caps, stub ends). The product range is identified from the product album; material grades, sizes, pressure classes and standards are not stated.
Is this listing CMH-verified?
Yes, on the registry check: active since 2016, manufacturing in scope, and a zero court record. It does not confirm the products, the capacity, the workforce or any certificate — none was supplied and the factory has not been visited.
Can Zhengshun export directly?
Not confirmed. The registered scope wording does not include import and export. Many small stainless fastener manufacturers in the Dongtai / Yancheng cluster export through a trading company. Ask for the export arrangement before placing the first order.
What standards do these products follow?
Not stated. Stainless steel fasteners for international markets typically follow DIN (Germany), ASTM / ASME (United States), JIS (Japan) or BS EN ISO (United Kingdom / Europe). Flanges follow ASME B16.5, EN 1092 or JIS B2220. Ask which standards the factory produces to and whether it can supply to a buyer-specified standard.
Is there anything negative on the record?
No. The risk check returned zero entries across all categories. The main open item is not a negative finding but an absence: no certificate, test report or export document is on record. The zero insured-employee count is a data point to verify during a site visit.

Send your specification: material grade (304, 316, 316L, duplex 2205), standard (DIN, ASTM, JIS, GB), sizes, quantities and any special finish (polished, passivated, hot-dip galvanised). For flanges state the pressure class (PN10, PN16, Class 150, Class 300) and facing (raised face, ring joint). Ask for the MOQ, lead time, material certificates (mill test reports to EN 10204 3.1), and copies of any ISO or product certification — none has been sighted here.
