The company describes manufacturing and exporting high-strength steel LPG gas cylinders from 0.5 kg to 50 kg for household, commercial kitchen, and industrial use. It states features including seamless construction, powder coating, batch traceability, and 100% hydrostatic testing with OEM options; this is company marketing copy only.

What certifications and awards does Hangzhou Tianlong Steel Cylinder Co., Ltd claim?

The company states it holds ISO 9001, ISO 14001, CE, and ISO 45001 certifications. It also lists BV / Bureau Veritas as a company-stated award. All of these remain company claims rather than independently confirmed items.

Where Hangzhou Tianlong Steel Cylinder Co., Ltd states something about itself, we show it beside the public record, so you are reading sourced facts, not marketing.
