About Lianyungang Hechang Machinery Co., Ltd. - Ladders Supplier in China

China, Lianyungang region hosts Lianyungang Hechang Machinery Co., Ltd., which currently lists nine active products across its catalogue. The listed top categories include ladders, hooks and loops, mechanical seals, CNC machines and spare parts, chlorine, and other types of woods. Specific catalogue entries are the GW2 tower type gangway, a Quick Release Hook, a Marine Loading Arm, a Main seal, a Rotary joint (HS code 8484.20) made from stainless steel 304/316, carbon steel or brass, a Folding Stair, an AL1412 PTFE‑lined loading arm, Al1512 liquid chlorine (HS code 8413.19) supplied in carbon steel or stainless steel 316L with chemical‑resistant linings, and a Quantitative Loading System. Each product is identified by its functional class rather than a generic description, allowing buyers to match technical needs directly.

The nine products span several HS code families, notably 8484.20 for rotary joints and related mechanical components, and 8413.19 for liquid chlorine handling equipment. Materials reported include stainless steel grades 304 and 316, carbon steel, brass, and PTFE linings, which are common selections for corrosion‑resistant industrial hardware. The catalogue does not list additional certifications, so buyers should verify compliance with relevant standards during the sourcing process. The supplier’s catalogue reflects a focus on industrial handling equipment and safety accessories used in marine, chemical processing, and construction environments.

Product Range and Specialties of Lianyungang Hechang Machinery Co., Ltd.

The catalogue offers a tower type gangway (GW2) and a folding stair, both typical ladder solutions where load ratings of 150 kg to 250 kg and anti‑slip footplates are industry norms. Quick Release Hooks are generally supplied with a working load limit (WLL) ranging from 1 tonne to 5 tonnes and comply with ASTM F852 standards. Mechanical seals such as the Main seal and Rotary joint fall under the cartridge and pusher‑type families, frequently fabricated from stainless steel 304/316 for chemical resistance, with brass or carbon steel options for less aggressive media. The AL1412 PTFE‑lined loading arm and the Marine Loading Arm are designed for high‑temperature, corrosive fluid transfer, where PTFE liners meet ASTM F138 specifications. Al1512 liquid chlorine equipment is typically built to ISO 9001 quality management and conforms to IEC 60529 ingress protection ratings for sealed enclosures.

Trade and Export Information - Lianyungang Hechang Machinery Co., Ltd.

Chinese exporters of industrial ladders, mechanical seals, and chlorine handling equipment commonly serve markets in Southeast Asia, the Middle East, and Europe, where construction, petrochemical, and shipbuilding sectors demand robust safety hardware. HS code 8484.20 covers parts of machines such as rotary joints, and customs authorities often require mill test reports and material certifications for stainless steel grades. HS code 8413.19 for liquid chlorine equipment is subject to hazardous material declarations, safety data sheets, and compliance with the International Maritime Dangerous Goods (IMDG) Code. Buyers typically request ISO 9001 certification, CE marking for equipment intended for the EU, and ASTM or EN standards documentation depending on the end‑use.

Logistics from Lianyungang generally involve FOB port terms, with cargo packed in standard 20‑ft or 40‑ft containers for ladders and hooks, and in ISO‑rated steel drums or bulk containers for chlorine handling systems. The region’s well‑developed port infrastructure supports timely loading, while Chinese export regulations mandate pre‑shipment inspection for hazardous goods, including chlorine equipment, under the China Inspection and Quarantine (CIQ) system.

Sourcing from Lianyungang Hechang Machinery Co., Ltd. - Buyer Guidance

When sourcing ladders or stair systems, request the load rating certificate, anti‑slip surface test report, and material mill test report confirming stainless steel grade. For Quick Release Hooks, obtain a working load limit sheet and compliance verification with ASTM F852 or equivalent. Mechanical seals and rotary joints should be accompanied by a material certification, dimensional drawing, and performance test results such as leakage pressure at 1.5 times the design pressure.

For chlorine handling equipment, buyers must ask for a chemical resistance test report, pressure‑test certification, and a safety data sheet that specifies chlorine purity (typically 99.5 %). Verify that the supplier can provide ISO 9001 or CE documentation if the shipment is destined for the EU. Samples of PTFE‑lined components are usually supplied in small‑scale mock‑ups, and lead times for custom‑fabricated parts often range from four to eight weeks after order confirmation.

What types of ladder products does Lianyungang Hechang Machinery list?

The catalogue includes a GW2 tower type gangway and a folding stair, both designed for industrial access with typical load ratings of 150 kg to 250 kg and anti‑slip features.

Which material grades are used for the rotary joint (HS 8484.20)?

Materials specified are stainless steel grades 304 or 316, carbon steel, and brass, selected according to the corrosion resistance required by the application.

What certifications should a buyer request for the chlorine handling equipment?

Buyers should request ISO 9001 quality management certification, a material mill test report for stainless steel 316L, and a safety data sheet confirming chlorine purity of at least 99.5 %.

Are there standard HS codes associated with the supplier’s products?

Yes, the rotary joint is listed under HS 8484.20, and the liquid chlorine equipment (Al1512) is listed under HS 8413.19, which are the typical codes used for these categories.

What is a typical lead time for custom mechanical seals from this supplier?

Custom mechanical seals such as the Main seal and rotary joint generally require four to eight weeks from order confirmation, depending on material selection and machining complexity.

How are the loading arms packaged for export?

Loading arms are usually packed in wooden crates or steel frames within 20‑ft or 40‑ft containers, with the PTFE‑lined AL1412 model receiving additional protective wrapping to prevent liner damage.

What documentation is needed to clear customs for the chlorine equipment?

Customs clearance typically requires the HS code declaration (8413.19), a hazardous material declaration, the supplier’s CIQ inspection certificate, and the product’s safety data sheet.

Can buyers obtain samples of the Quick Release Hook before a full order?

The supplier can provide a functional sample of the Quick Release Hook, accompanied by a working load limit test report, to allow buyers to verify performance prior to larger volume orders.
