Import Bs1387 Galvanized Pipe — Buy in Bulk from Supplier in China

BS1387 galvanized pipe is a light-to-medium duty steel tube specified by British Standard 1387 for water, gas and air services, with a zinc coating applied by hot-dip galvanizing. The standard specifies three grades of pipe: light, medium and heavy, each with defined wall thicknesses and permissible variations. Cangzhou Shenlong Pipe Manufacturing Co., Ltd. produces this pipe to BS1387-1985 (or its successor standards), with the zinc layer typically measuring 65 microns or more to provide the corrosion protection that distinguishes galvanized from black pipe. The supplier's address is listed in Beijing's Chaoyang District, though Cangzhou in Hebei Province is the actual centre of China's welded steel pipe industry.

The base steel is typically low-carbon structural steel to EN 10025 or Chinese GB/T 700 standards, with carbon content kept below 0.25% to ensure weldability and formability. Hot-dip galvanizing involves immersion in molten zinc at approximately 450°C, forming zinc-iron alloy layers bonded metallurgically to the steel surface. The coating weight for BS1387 pipe typically ranges from 300 to 610 g/m² depending on grade and customer specification, with heavier coatings requested for aggressive environments. End finishes include plain, screwed and socketed, or bevelled ends to suit different jointing methods. Threading conforms to BS 21 or ISO 7/1 where screw-and-socket joints are required.

Contractors and industrial buyers source BS1387 galvanized pipe for low-pressure water lines, fire protection systems, fencing, handrails, and structural tubular applications where atmospheric corrosion resistance is needed but the higher cost of stainless steel is not justified. The pipe is not rated for high-pressure or high-temperature service; BS1387 itself is withdrawn and superseded by EN 10255, though the designation remains widely used in export markets. Buyers should confirm with Cangzhou Shenlong whether the pipe is certified to the original BS1387, to EN 10255, or to equivalent Chinese standards such as GB/T 3091. Packaging is typically in hexagonal bundles or loose bulk, with plastic end caps to protect threads and coating during handling.

Cangzhou Shenlong Pipe Manufacturing Co., Ltd. is registered with an address on Guangqu Road in Beijing's Chaoyang District, though this may be a commercial or sales office rather than the manufacturing location. The company's trust tier is classified as 'harbor' and its supplier tier is 'imported', which in marketplace terminology indicates a non-verified or lower-assurance profile rather than a platform-verified status. The response rate is recorded at 0.00 with an average response time of zero hours, strongly suggesting that no enquiry response data is available for this listing. Buyers should treat direct communication as essential, not optional, when considering this supplier.

The listing provides no information about factory location, production capacity, quality management system certification, or export experience. The source description makes reference to ISO and CE certifications, though these are presented in generic platform marketing language rather than as verified documents attributable to this specific supplier. No years in operation, employee count, revenue figures, or named clients are stated in the available data. The supplier's name references Cangzhou, a city in Hebei Province that is indeed China's largest concentration of welded steel pipe manufacturing, but this geographic association alone does not confirm production capability. Buyers should request a factory audit, mill test certificates for actual production lots, and copies of any claimed certifications before placing trial orders.
