20'HC
BOXWELL
The 20'HC Full Side Opening Container provides extensive access along the side of the container, offering greater loading flexibility than a conventional dry cargo container that relies mainly on end-door access.
The side-opening configuration is particularly useful when cargo is difficult to position through standard end doors. It also allows operators to access different areas of the cargo space without unloading items from front to back.
This makes the container suitable for handling:
● Palletized goods
● Industrial equipment
● Bulky cargo
● Wide components
● Irregularly shaped cargo
● General cargo requiring frequent side access
Full-side access delivers significant operational advantages for forklift loading, bulky cargo handling, and rapid access to stored goods.
The 20'HC configuration combines a compact 20-foot footprint with an extra-height 9'6" high-cube format.
This makes the product ideal for projects that require a 20-foot container configuration while also benefiting from additional vertical cargo space.
Exact external dimensions, internal dimensions, and door-opening clearances are manufactured strictly according to approved engineering drawings.
The container is manufactured using high-strength structural steel.
Precision CNC cutting and standardized welding processes are used during fabrication to maintain structural stability and manufacturing consistency.
Because the side wall incorporates a wide opening area, the structural frame and door headers are specifically reinforced and engineered to maintain full ISO structural integrity.
Before painting, the steel structure undergoes Sa2.5 abrasive blast cleaning.
The specified heavy-duty coating system consists of:
● Zinc-rich epoxy primer
● Epoxy intermediate coat
● Acrylic top coat
Paint dry film thickness (DFT) and coating adhesion are strictly inspected during production.
This coating system protects the steel structure against corrosion during long-term transportation, outdoor storage, and harsh marine shipping conditions.
This container is designed and manufactured in full compliance with ISO 1496-1 requirements for multimodal logistics applications.
Its side-opening structure provides superior cargo accessibility while retaining the full structural strength, stackability, and transport functionality of a standard ISO freight container.
The 20'HC Full Side Opening Container is designed for logistics and storage applications where wide lateral access improves cargo loading, unloading, and retrieval efficiency.
Side access streamlines the handling of palletized goods by allowing direct forklift access along the entire length of the container, eliminating the need to move pallets sequentially through end doors.
Machinery and equipment with dimensions that make conventional end-door loading difficult benefit directly from the wide side-opening configuration.
The loading arrangement is optimized according to:
● Equipment dimensions
● Equipment weight
● Center of gravity
● Handling equipment
● Cargo securing requirements
Large or irregularly shaped components that are difficult to maneuver through conventional end doors can be placed easily through the unobstructed side opening.
Unlike conventional dry containers that require unloading front-loaded goods to reach items in the rear, full-side doors allow direct access to any section of the container, making it ideal for mobile workshops, dynamic job-site storage, and multi-drop distribution operations.
Our containers are engineered for seamless multimodal logistics shipments across global ports and inland networks, fully compliant with approved specifications, CSC standards, and international carrier regulations.

Every offshore container passes through a complete manufacturing process under strict quality control.
Qingdao Boxwell Container Co., Ltd. was founded in May 2020 in Jiaozhou, Qingdao.
Our manufacturing base covers approximately 60,000 m², including 32,000 m² of modern workshop space, operated by more than 200 skilled workers.
This production facility supports standard ISO shipping containers, specialized open-side units, customized equipment enclosures, and modular container products.
Our core engineering and R&D team brings more than 20 years of direct industry experience in offshore containers, special ISO containers, and customized containerized equipment solutions.
We support build-to-print manufacturing from customer drawings as well as full in-house custom design for non-standard container applications. Our engineers collaborate with clients from technical review through structural analysis and final production. This technical capability ensures that special door configurations, such as full-side opening models, maintain structural integrity and certification compliance.
Our quality management system covers:
● Raw material inspection
● Production process monitoring
● Final product testing
Advanced testing equipment is utilized throughout production to guarantee product consistency and reliability.
We operate a dedicated in-house ISO/CSC certification testing facility equipped with professional test rigs to perform full proof-load, racking, and structural testing, ensuring valid CSC certification for international transport.
Our comprehensive service portfolio includes:
● Pre-sales technical consultation
● Engineering and solution design
● Production monitoring
● Quality control
● Third-party inspection support
● Logistics and shipment coordination
● After-sales technical support
Located approximately 20 km from Qingdao Port, our primary export terminal, we provide rapid delivery and streamlined ocean logistics. Shipments via other designated ports can also be coordinated to meet project requirements.
It is a 20-foot high-cube (9'6" high) ISO shipping container designed with full-length opening side doors in addition to or in place of conventional end doors, providing unobstructed lateral access.
The main advantage is total lateral cargo accessibility. Forklifts can load and unload directly from the side, simplifying the handling of bulky machinery, long items, and palletized freight, while allowing selective retrieval of goods without unloading the entire container.
No. This is a dedicated 20-foot high-cube model (20'HC Full Side Opening). The 40'HC version with a middle post is a separate, larger model engineered specifically for 40-foot spans.
Standard configurations can be supplied with a rigid, hinged, or removable center post depending on customer operational requirements and structural design specifications.
Typical applications include:
● Palletized cargo
● Industrial machinery
● Large components
● Bulky cargo
● Irregularly shaped goods
● Cargo requiring side access
Yes. Full-side opening containers are specifically engineered to facilitate rapid and safe forklift loading directly across the full length of the container floor.
The 20'HC configuration combines the compact ground footprint of a 20-foot container with an extra foot of vertical clearance (9'6" external height), providing extra internal cubic capacity for taller cargo.
The container is fully designed, fabricated, and tested in accordance with ISO 1496-1 standards for Series 1 freight containers.
Yes. Every container is supplied with a valid CSC Certificate and safety approval plate for international multimodal shipping.
CSC certification is supplied as standard. Classification society certification from Lloyd's Register (LR), ABS, BV, CCS, or DNV can be provided based on project requirements.
No. This is an ISO shipping container designed for multimodal freight and commercial storage. For offshore energy applications, we supply dedicated DNV-ST-E271 / EN 12079 certified offshore CCUs.
No. Standard ISO containers comply with ISO 1496-1 and CSC. DNV-ST-E271 and EN 12079 apply specifically to our offshore container series.
Standard ISO containers undergo ISO 1496-1 proof-load and structural testing. Non-destructive testing (NDT) and offshore dynamic lifting tests are performed specifically for offshore CCU orders.
The structure undergoes Sa2.5 shot blasting followed by a three-coat marine paint system:
● Zinc-rich epoxy primer
● Epoxy intermediate coat
● Acrylic top coat
Yes. We offer extensive customization for door configurations, internal tie-down rings, heavy-duty flooring, and removable post designs based on customer drawings and specifications.
Exact tare weight, payload capacity, and door clearances vary slightly depending on custom customer selections (such as door hardware, floor materials, and internal structural options). Final verified parameters are provided on the approved technical drawings and CSC plate for each order.
