Shipping containers – find manufacturers and suppliers

Sea containers, also known as freight containers, are robust and standardized transport containers that have been specially developed for the worldwide transport of goods by ship, truck and rail.

They are indispensable in logistics and have also found many other applications.

Below you will find the properties and types of sea containers, their areas of application and their advantages:

Characteristics of sea containers:

1. Standardized dimensions:
   Sea containers come in set sizes, usually 20 feet and 40 feet long, which allows for standardized handling and storage.
   This means that containers can be easily exchanged between different means of transportation (ship, rail, truck).
2. Robust construction:
   Usually made of weatherproof and corrosion-resistant steel, they are built to withstand extreme weather conditions at sea.
   The corners are specially reinforced to allow several containers to be stacked on top of each other.
3. Load securing:
   Sea containers have attachment points (lashing eyes) on the floor and walls to secure the cargo.
   This is particularly important to protect the cargo from shifting and damage during transportation.
4. Ventilation and insulation:
   Many containers have built-in vents to allow air circulation and reduce condensation.
   Specialized containers, such as insulated or refrigerated variants (refrigerated containers), provide additional temperature control.
5. Locking system:
   Containers are fitted with robust double doors, located at one end, with sturdy latches and seals to lock the cargo securely and protect it from the weather.

Types of sea containers:

1. Standard containers (dry van):
   These containers are the most widely used and are suitable for the transportation of standard cargo.
2. Reefer containers:
   These containers are equipped with refrigeration units that allow temperature control and are suitable for the transportation of perishable goods such as food and medicines.
3. Insulated containers:
   These offer temperature stability and are ideal for goods that do not require refrigeration or heating but are temperature sensitive.
4. Open-top containers:
   These containers do not have a fixed roof, so oversized cargo such as machinery or building materials can be loaded from the top.
5. Flat-rack containers:
   These containers have no side walls and are ideal for transporting bulky and heavy goods that exceed the dimensions of a standard container.
6. Tank containers:
   These containers are designed for the transportation of liquids and hazardous goods and have special tanks in the container frame

Use of sea containers:

1. Cargo transportation:
Sea containers are mainly designed for the international transportation of goods and are used on ships, trains and trucks. They enable the fast and efficient transportation of a wide variety of goods worldwide.

2. Temporary storage of goods:
Ports, logistics centers and warehouses use containers for short-term or long-term storage of goods. They are weatherproof and lockable, making them a secure solution for storage.

Advantages of sea containers:

• Sea containers are built tough and can withstand extreme conditions, making them safe and durable both on the high seas and on land.
• Due to their standard size and stackability, containers can be transported efficiently on ships, trains and trucks. This significantly reduces transportation costs.
• Containers can be easily converted and used in a variety of ways. They are ideal for temporary and mobile applications.
• The reuse and repurposing of sea containers as storage space, living space or for other purposes is sustainable and environmentally friendly, as it promotes recycling and saves resources.

Sea containers have become an integral part of global logistics and have also established themselves in many other areas of application. Their robust construction, weather resistance and transport flexibility make them an ideal container for international freight transportation.

Here are the most important aspects to look out for when buying sea containers:

When buying sea containers, there are important criteria that are decisive depending on the intended use, quality and condition of the container.

• Depending on requirements, a standard container (dry van), refrigerated container (reefer), insulated container, open-top container, flat-rack container or a tank container may be required. The type of container should match the intended use.
• New containers are more expensive, but offer the longest shelf life and no signs of wear and tear. Used containers are cheaper, but the condition can vary greatly.
• Containers are often offered in "One-Way", "Cargo-Worthy", "Wind & Watertight" and "As-is" (as seen). For storage and transportation purposes, "Cargo-Worthy" and "Wind & Watertight" containers are often sufficient, as they are still in good condition and safe.
• Look out for corrosion damage, dents or structural damage in used containers. Well-maintained containers are particularly important for long-term use as storage containers.
• The floor in particular should be intact and free of cracks. The door seals should also be watertight and functional to protect the contents from moisture and pests.
• The most common container sizes are 20 feet and 40 feet, but there are also high-cube containers (with extra height) and other special sizes.
• Make sure that the location offers sufficient space for the container and the necessary transportation or lifting equipment.
• Standard containers usually have simple ventilation. If required, additional ventilation systems can be installed to prevent condensation and moisture damage.
• A refrigerated container is required for temperature-sensitive goods or special storage conditions. Reefer containers are equipped with refrigeration units and allow precise temperature control.
• For the transport or storage of goods that require constant temperatures, insulated containers are helpful to minimize temperature fluctuations.
• Containers should have stable, functioning locking systems to keep the cargo safe. Additional locks or security devices can be fitted for valuable or sensitive goods.
• Make sure that the container is free of harmful substances. older containers can sometimes contain residues of harmful substances (such as chemical residues or paint).
• The costs for transporting the container are often considerable. Plan these costs in advance and make sure that the provider offers transportation solutions or cooperation.
• If containers are to be stacked, e.g. for modular buildings or warehouses, make sure that the container is stable enough and suitable for stacking.
• If the container is to be used for international transportation, a valid CSC (Container Safety Convention) sticker is required to confirm its suitability for transportation.
• For used containers, current test reports or certificates can be helpful to confirm the condition and suitability of the container for certain applications.
• The purchase price should be in reasonable proportion to the planned service life and the condition of the container. A higher price for a new or specialized container can pay off in the long term if it requires less maintenance.

When purchasing sea containers, you should carefully consider the intended use, container type and condition. The choice between new and used containers, the right size and the condition (especially doors, seals and floor) are decisive factors. Also pay attention to possible transportation and installation costs and ensure that all safety and quality standards are met. A well-chosen container can be used for a long time and adapted to changing requirements.

Sea containers can be purchased from various suppliers. Comprehensive information about manufacturers and suppliers of Sea containers from all over the world can be found on Exportpages.
