What types of shipping containers does CIMIC supply?

We manufacture and export reefer (refrigerated) containers, dry cargo containers, offshore containers, insulated containers, tank containers, modular containers and special containers such as side-open-door, roll-up-door and open-top units. Used reefer and used dry containers are also available.

Can you build customized OEM/ODM containers?

Yes. We accept tailor-made OEM and ODM orders. Our engineers review your cargo, route and operating environment, then confirm a drawing covering size, door configuration, insulation, refrigeration unit and finish before production begins.

Which certifications and standards do your containers meet?

CIMIC holds a BV (Bureau Veritas) shipping certificate and an ISO quality certificate. Standard units follow ISO container dimensions, and our offshore dry cargo containers are manufactured in line with DNV certification requirements for offshore service.

Which refrigeration unit brands are available for reefer containers?

Our reefer range includes models fitted with Thermo King, Daikin and Carrier refrigeration units, offered in 10ft, 20ft, 20ft high-cube, 40ft and 40ft high-cube sizes depending on the model.

Where are your used containers located?

Our second-hand containers are stored at various ports in China. We share condition details and photos of the specific units on request so you can approve them before shipment.

Where is CIMIC located and which markets do you serve?

We operate from Tianjin and Suzhou, China, about 100 km from the seaport. Our containers are exported worldwide, with Africa, Europe and the Americas as our main markets.

Global Procurement Architecture for ISO 20 Containers

Navigating structural integrity, raw material chemistry, and regulatory requirements in modern supply chains.

The standard ISO 20 container (specifically the 20-foot General Purpose / ISO 1CC profile) operates as the empirical baseline for intermodal transport globally. As intermodal operations transition from straightforward oceanic and rail haulage into high-stress edge deployments—such as mobile BESS (Battery Energy Storage Systems), modular data processing modules, deep-sea exploration pods, and dangerous chemical transport—the mechanical engineering parameters of container fabrication require comprehensive recalibration. Sourcing teams can no longer view a 20ft container merely as a commodity box; it is an engineered pressure and structural envelope operating in aggressive saline and dynamic stress environments.

Modern procurement demands an end-to-end evaluation of the steel substrate. Our manufacturing ecosystems standardize exclusively on high-tensile SPA-H atmospheric corrosion-resistant Corten steel. Corten-A and Corten-B cold-rolled profiles deliver exceptional yield points (typically ≥ 345–355 MPa), resisting structural degradation under intensive 9-high fully loaded stacking regimes (≥ 192,000 kg total corner post capacity). When combined with low-VOC, multi-stage zinc-rich primer treatments and cross-linked polyurethane topcoats, our production output provides predictable lifecycle resilience across Arctic rail corridors, deep-equatorial shipping lanes, and dynamic offshore platforms governed by DNV GL / Bureau Veritas validation protocols.

Structural Integrity & Alloys

Fabricated with cold-rolled SPA-H alloy framing. Floor crossmembers withstand minimum fork-truck axle dynamic loads of 5,460 kg (7,260 kg optional), strictly compliant with ISO 1496-1 testing directives.

Corrosion & Thermal Barrier

Blast cleaned to ISO Sa 2.5 profile before automated application of zinc-rich epoxy primers. Thermal variations are eliminated with closed-cell polyurethane or vacuum insulation panels (VIP) for refrigeration units.

Traceable Quality Control

Every serial production run executes non-destructive testing (NDT), dye-penetrant checks on corner casting welds, continuous door gasket water-spray tests under 100 kPa pressure, and full Bureau Veritas classification sign-offs.

Strategic Use-Cases

Macro-Sector Engineering Solutions

Transforming standard ISO 20 platforms into resilient mission-critical industrial assets.

Procurement Advisory

Frequently Asked Technical Questions

Direct answers for freight forwarders, fleet managers, and industrial contractors.

What specific certifications guarantee your containers meet marine safety standards?

All containers manufactured in our facilities comply with ISO standards (ISO 668, ISO 1161, ISO 1496-1). They carry Bureau Veritas (BV) or alternate IACS-member classification approvals, complete with certified CSC (International Convention for Safe Containers) safety plates, guaranteeing structural clearance for marine stacking, rail haulage, and road chassis transit.

What makes Corten steel (SPA-H) superior for intermodal container fabrication?

SPA-H atmospheric corrosion-resistant steel develops a dense, self-healing oxide patina when exposed to airborne electrolytes and saltwater mist. This metallurgical property halts internal oxidation progression, drastically reduces maintenance overhead, and ensures structural lifespan exceeding 15–20 years in heavy industrial service.

How do you handle custom side-doors, open tops, and high-cube modifications?

Our OEM/ODM engineering protocol initiates with 3D structural modeling and finite element analysis (FEA). We re-engineer header beams, sill assemblies, and corner posts to maintain original ISO load ratings even with significant wall perforations or side-access roll-up installations.

Can used shipping containers be certified for new international maritime shipping?

Yes. Our stock of second-hand and used containers situated across major Chinese coastal hubs undergoes physical inspection by certified container surveyors. Cargo Worthy (CW) status and updated CSC validity can be issued prior to international vessel loading.

What thermal profiles can be maintained in specialized 20ft/40ft reefer containers?

Our reefer solutions, powered by Carrier Transicold, Thermo King, or Daikin machinery, support thermal regimes ranging from -35°C to +30°C (with specialized ultra-deep freezers reaching -60°C), making them indispensable for pharmaceutical, fresh produce, and seafood cold-chains.
