Custom OEM Multimodal Freight Transport Manufacturers & Exporter

Q355B structural steel is a low-alloy, high-strength European/Chinese standard steel that offers an optimal balance of yield strength (minimum 355 MPa) and tensile strength (470-630 MPa). Compared to standard Q235 steel, Q355B allows engineers to design larger clear-span structures without center columns, maximizing internal floor space for automated forklift movement and high-density warehouse rack systems while reducing overall frame weight.

Custom OEM containerized cold storage units are fabricated according to ISO 668 dimensions, equipped with standardized corner castings and forklift pockets. This engineering permits direct loading onto container ships, flatbed chassis trucks, and double-stack rail cars. Units feature integrated genset power options, allowing seamless thermal control throughout maritime transit and overland truck haulage without opening the cargo envelope.

FCL (Full Container Load) dedicates an entire 20ft, 40ft, or 40HQ container to a single consignee, eliminating intermediate handling risk and providing optimal volumetric pricing for heavy or high-volume equipment. LCL (Less than Container Load) consolidates multiple smaller shipments into a single container. For heavy structural components, LCL utilizes specialized crating and dunnage to prevent cargo shift, making it cost-effective for partial project deliveries.

We primarily engineer structures with Polyisocyanurate (PIR) or Polyurethane (PUR) core sandwich panels ranging from 100mm to 200mm in thickness. PIR panels provide superior fire resistance (B-s1, d0 classification) and exceptional thermal conductivity as low as 0.022 W/m·K. Double tongue-and-groove joint design with internal cam-locks prevents thermal bridging, ensuring stable internal temperatures down to -30°C for deep-freeze storage.

Under DDP terms, our enterprise assumes full operational and financial responsibility for the shipment from our production facility to your designated warehouse site. This encompasses ocean/air freight booking, origin export clearance, ISF/AMS filings, destination customs duty calculation, import tax settlement, and final inland flatbed truck delivery—eliminating administrative burden and unexpected demurrage charges for the buyer.

Required compliance documentation includes Mill Test Reports (MTRs) certifying Q355B chemical and mechanical properties, CE certificates, AWS D1.1 or EN 1090 welding process approvals, Commercial Invoices detailing HS Codes (such as 7308.90 for structural steelwork), Packing Lists detailing itemized piece counts, and ISPM 15 wood packaging heat-treatment certificates for timber dunnage.

Yes, our engineering team uses SAP2000 and PKPM structural design software to customize load parameters based on your jobsite zip code or port coordinates. We calculate exact dead load, live load, snow load, seismic zone coefficients (up to Magnitude 8), and wind load tolerances (up to 180 km/h) by adjusting steel section profiles, purlin spacing, and high-tensile bolt connection matrices.

Every structural member and containerized unit undergoes rigorous quality assurance: Ultrasonic Flaw Detection (UT) on critical structural welds, Magnetic Particle Inspection (MPI), dry film paint thickness measurement (DFT gauge), dimensions tolerance verification per ISO 2768, and 24-hour pre-shipment refrigeration unit run-testing for cold storage products.
