Designed for chemical, hydrogen, and LNG facilities – perfect for Purchasing Managers, Technical Directors, and Operations Leaders who need reliable, cost‑effective, and compliant storage solutions.
Corporate purchasing teams across the USA and Europe report three recurring pain points:
According to the IEA Gas 2026 report, 22% of new gas‑storage projects in Europe were postponed because the selected tank did not meet the latest CE‑Mark and ISO standards.
If you’re still wrestling with these issues, you’re likely seeing:

Our pontoon floating roofs have been deployed in the following contexts:
storage-tank-floating-roof tank-oil-and-gas tank-lng storing-hydrogen
All models meet the ISO 9001:2015 quality system, and the floating‑roof seal conforms to ASME Section VIII Division 2 criteria for high‑pressure vessels.
Standard models (5‑2 000 m³) are shipped within 6 weeks after order confirmation. Custom dimensions add 2‑4 weeks depending on engineering complexity.
Yes. Our R&D team holds ASME‑certified expertise in hydrogen‑compatible alloys (SA‑387 Gr 22, 5083‑H116) and can deliver a fully‑customized pontoon roof with integrated leak‑detection sensors.
Every unit ships with CE, ASME, ISO 9001, DNV‑GL, and where required, API 650, RoHS, and FCC certificates. Full documentation is provided in both English and the local language of the buyer.
We operate a dedicated export team. For the USA, we use DOT‑approved containers and can arrange C‑TPAT‑approved customs clearance. In Europe, we partner with bonded warehouses in Rotterdam and Hamburg to minimise import duties.
All tanks come with a 24‑month warranty covering material defects, plus an optional 5‑year extended service contract that includes annual inspections, seal replacement, and remote monitoring.
Limited‑time offer: Free 1:1 engineering consultation + complimentary 1‑ton sample roof panel (shipping on us).
