Open Top Container Rental
Open Top container rental from HZ KONTEJNERY s.r.o. represents a highly specialized service for the transport and temporary storage of items that exceed the capabilities of standard closed containers in terms of size, shape, or weight. Open Top is a variant of a transport container with an open upper part protected by a robust tarp, which allows vertical loading and unloading with a crane as well as handling of bulky or heavy loads that cannot be loaded through doors.
HZ KONTEJNERY s.r.o. provides not only the container itself, but also comprehensive logistical support: consulting, transport to the site, possible ConFoot leg rental, removal after the rental period ends, and technical assistance. The service is ideal for short-term projects, construction, industrial orders, as well as for private customers with one-time needs.
In-Depth Technical Analysis of Open Top Containers
Construction, Materials, and Key Elements
Material:
Open Top containers are manufactured from special CORTEN steel with additions of copper, nickel, chromium, and phosphorus. This alloy excels in high resistance to weather influences, corrosive environments, and mechanical stress. CORTEN creates a protective patina on the surface that prevents further rusting.
Reinforced Construction:
The missing solid roof is compensated by significantly reinforced upper and lower longitudinal members, corner posts, and massive cross members. This ensures sufficient rigidity for stacking and transport of heavy loads.
Removable Tarp:
The roof is formed by a strong PVC or PE tarp (often 650–900 g/m² in weight) with high UV and water resistance, secured to robust aluminum or steel frames and ropes around the perimeter. The tarp can be easily rolled up or removed for quick access from above.
Roof Bows:
Removable steel cross members serve to prevent the tarp from sagging. These cross members can be removed during loading, allowing full use of the roof opening width and length.
Rotating Roof Header Bar:
A rotating or hinged upper beam is located at the doors, which can be removed before loading to ensure passage of items taller than the door frame.
Standard Front Doors:
The doors are double-leaf, equipped with lockable handles and sealing, allowing standard horizontal loading and cargo securing.
Lashing Rings:
Fixed lashing eyes are distributed across the floor and walls (minimum load capacity 1,000–2,000 kg per eye) for secure cargo securing with straps or chains according to EN 12195-2 standard.
ISO and CSC Certification:
Open Top containers are subject to ISO 668, ISO 6346 standards and the CSC (Container Safety Convention) safety certificate, which allows their use in international transport and stacking up to six layers.
Specifications and Dimensions (20′ and 40′ OT)

Cargo worthy container
If you have ever shopped for a used shipping container, you have almost certainly encountered the term cargo worthy — often abbreviated as CW or CWO (Cargo Worthy Only). It is one of the most important classifications in the container industry, yet it is also one of the most misunderstood. A cargo worthy container is not a container that looks new. It is not necessarily a container that has a valid CSC plate. And it is definitely not the same as a wind and watertight container. This guide explains what cargo worthy really means — from its technical definition and historical origins to the precise structural criteria, inspection process, cost implications, and common misconceptions that trip up even experienced buyers.
Shipping container home
A shipping container home is a residential dwelling constructed from one or more steel intermodal containers — the same standardized metal boxes that transport goods across oceans, railways, and highways. These containers, engineered from corrosion-resistant Corten steel and designed to withstand brutal maritime conditions, are repurposed into fully habitable living spaces through insulation, structural modifications, and the installation of all standard residential utilities. A shipping container home can range from a minimalist 160-square-foot studio built from a single 20-foot container to a sprawling multi-level compound combining dozens of 40-foot high-cube units.
Core Definition: A shipping container home is a code-compliant, habitable structure built from one or more steel intermodal shipping containers that have been insulated, structurally reinforced where modified, and fitted with windows, doors, plumbing, electrical systems, and interior finishes to function as a permanent or semi-permanent residence.
Corner casting steel vs aluminum
Every shipping container in the world — all 40 million of them — rests on eight critical components. Corner castings are the load-bearing blocks at each corner of an ISO shipping container, and they are the universal interface between the container and every crane, twistlock, spreader, and chassis on the planet. When you lift a container, stack it nine high on a ship, or lock it to a truck trailer, every ton of force flows through these fittings.
Shipping container bar conversion
A shipping container bar conversion transforms a standard steel intermodal container into a fully functional beverage service space. What began as an experimental concept in the mid-2000s has matured into a legitimate hospitality format — one that now powers everything from backyard home bars to multi-six-figure commercial venues. This guide covers every dimension of a shipping container bar conversion: what it is, what it costs, how to build one, the regulations you cannot ignore, and whether the business model actually works.
