Explore our export-certified hazardous cargo enclosures, offshore cold-chain equipment, and heavy-payload bulk units manufactured under Bureau Veritas, DNV, and ISO quality management protocols.
From passive Corten steel boxes to active, explosion-proof, thermally monitored intermodal containment architectures across global maritime and rail networks.
The global surge in electrochemical storage systems requires Class 9 DG containers engineered with early-stage thermal runaway off-gas sensing (CO, H2, and VOCs), integrated aerosol suppression, and pressure-activated blast relief panels conforming to NFPA 69 and 855 standards.
Stringent EPA and European ADR environmental protection directives dictate built-in bunding capacities (typically ≥110% of the largest vessel volume) with spark-resistant, chemical-proof floor sumps, stainless steel drainage ball valves, and non-corrosive FRP grating.
Decarbonization drives demand for T75 vacuum-insulated liquid nitrogen, argon, CO2, and LNG tank containers. Engineered with ASME VIII / EN 13530 pressure vessels and multi-layer insulation (MLI), maintaining thermal hold times exceeding 30 to 45 days during intermodal transit.
Cross-border procurement of hazardous goods enclosures requires flawless adherence to multilateral treaties and testing parameters to eliminate demurrage, fines, and structural failure.

Combining heavy metallurgical engineering, intelligent robotics, and deep maritime hub synergy from Tianjin and the Yangtze Delta to deliver unparalleled cost-to-performance metrics.
Our structures utilize certified SPA-H weathering steel (yield strength ≥355 MPa) and cryogenic-grade austenitic stainless steel. Automated submerged arc welding (SAW) and pulsed MIG ensure porosity-free structural joins capable of resisting severe flexural and torsional racking forces during sea voyages.
Surface preparation strictly adheres to SA 2.5 shot-blasting standards. Coatings are applied in humidity-controlled climate bays: 70μm zinc-rich epoxy primer, 100μm micaceous iron oxide intermediate barrier, and 50μm aliphatic polyurethane topcoat, guaranteeing over 15 years of corrosion protection.
Every batch undergoes stringent QC: 100% radiographic or ultrasonic examination on critical pressure welds, hydraulic pressure tests at 1.5x design pressure, corner post 86,400 kg compressive stack loading, and drop-impact tests at low operating temperatures to verify weld ductileness.
Engineered to protect life, environment, and cargo across severe geographical, oceanic, and operational extremes.
North Sea, Gulf of Mexico, and West African shelf operations mandate DNV 2.7-1 certified chemical dosing skips, cuttings containers, and reefer modules. Featuring certified 4-leg sling sets, non-sparking locking mechanisms, and sacrificial anodes to withstand heavy brine spray and dynamic marine lifting.
Australian Pilbara iron ore fields and Latin American lithium salars utilize custom half-height open-top containers and self-tipping containers. Fabricated from Hardox 450 abrasion-resistant wear plates to handle aggressive ore impacts, chemical leachates, and rapid payload discharges.
Intermodal transit of hazardous reagents, pesticides, and flammable adhesives across Eurasian rail lines and transatlantic sea passages. Incorporates full insulated jackets, internal steam heating tubes, electrical heating trace conduits, and PTFE-lined chemical containment chambers.
Comprehensive engineering, regulatory, and commercial answers for EPCs, procurement heads, and hazardous cargo logistics managers.
