Why you should buy Shipping Containers

Wednesday, September 21, 2016

Whatever the reason you are considering purchasing a shipping container, whether it be for personal or business purposes, it is a cost-effective method to install a secure, mobile unit on a construction site, at your business place, in your yard or for any other purpose for that matter. Let’s explore the reasons why you should buy shipping containers.

  • Depending on your location, purchasing a new shipping container is a breeze, especially with a reputable company like SEA Containers NZ who have branches nationwide.
  • If you don’t want to spend exorbitant costs or your business is on a tight budget, you can buy used shipping containers and can achieve huge savings. While the quality is not the same of a new container, it can be utilised for storage and transport purposes.
  • Be aware that not all shipping containers are constructed of the same material. Opt for those made from corten steel. These will last longer and can endure catastrophic weather conditions. Bear in mind that shipping containers are designed to transport cargo across the oceans while being exposed to the corrosive salt air.
  • Purchase containers that have been graded to ensure that you obtain a unit that is secure, and suited to your requirements, especially if needed for long term use.
  • There are millions of unused shipping containers stacked in ports and shipping yards around the world that are now being put to good use. You can contribute in a small but notable way by buying these recycled containers and creating eco-friendly alternatives for these modified containers.
  • There is an increasing trend to use shipping containers as mobile farming. Many cities are becoming over populated, and access to land is becoming more difficult. Making it more attainable for city dwellers to get wholesome, fresh foods. Weather conditions do not affect the harvesting of fresh produce.
  • If you purchase a container instead of leasing one, it does not mean money down the drain. Companies are always on the lookout for good quality containers for storage and transport purposes. They are durable and robust and designed to withstand a tough life carrying cargo for over 20 years. Hence, if you no longer require the containers, you are assured that they have good trade value over time.
  • Investing in shipping containers gives you peace of mind when constructing a home, or a site office, small studio, etc., especially in areas like Christchurch, Wellington that is prone to earthquakes, or other coastal parts of New Zealand, as container buildings offer immense durability and sustainability. Your Intermodal Steel Building Unit or ISBU unit is sure to impress your insurance provider, due to its excellent safety and fire ranking. Therefore, don’t neglect to inform your insurance provider that it is an ISBU or Intermodal Steel Building Unit.

There are many advantages to purchasing a container due its adaptability and functionality.

Reasons why Shipping Containers are a Better Alternative to Traditional Modular Structures

Thursday, September 01, 2016

Shipping containers are recycled and used in various innovative ways. Recycled shipping containers have transformed from the simple, durable box to creative designs. Are you contemplating as to whether shipping containers are a viable option in comparison to traditional modular buildings? Listed below are reasons why shipping containers are a more feasible option.


Shipping containers are made out of corrugated steel that can withstand being hauled onto ships and transported all over the world. It is unbelievably difficult to break into, therefore the most secure working space in the market.


Shipping containers have a lifespan of about 25 years on average and is still salvageable afterwards. It is highly unlikely that you possess a capital asset that has longevity and is still functional in 25 years time. The bonus is that it is relatively easy to maintain.

3.Weather-proof, Water-tight and Vermin proof

Storage containers constructed to ISO standards are designed to withstand severe weather conditions to safeguard valuable cargo they transport across the oceans. If you are looking for a durable structure, that can withstand the elements and keep rodents at bay; container structures will do the job.

4.Suitable Logistically

Due to developments in the use of intelligent logistics, shipping containers are inherently advantageous to clients. They are designed to be easily transportable via rail, truck, air or sea. Manufacturers are also incorporated logistics handling aspects in container design. In so doing, these durable structures are accessible to haul, shift and stack.

5.Constructed to dispatch

Expediting freight is the norm in the modular construction business and lasting; steel shipping containers provide several distinctive advantages in comparison to traditional modular structures. Here are a few examples:,

•Temporary, compact structures that are mobile

•Relatively easy and quick to install with no particular stairs, ramps, or skirting as they are positioned at ground level

•Uncomplicated and rapid turnkey electrical and plumbing connected onsite.

•Fitted foundations, therefore, no pre-installation or advance work is needed.


Shipping containers are designed and engineered to cart heavy loads and stacked in towering columns. They have standard height and length measurements, therefore, offer modular elements. If you have limited space, they are an ideal solution for a compact footprint.


At SEA Containers NZ we work in collaboration with a committed team who specialise in modifying and customising containers. We merged our talents and combined have considerable engineering and fabrication skills that allow us to offer a nearly limitless range of shipping container modifications and container solutions. We are also able to modify and convert containers for specified uses, namely;

•Hazardous/Dangerous Goods storage units

•Static or Mobile Workshops

•Site offices

•Retail kiosks/outlets

•Accommodation units and more.

Bear in mind that we will go over and above the norm and tailor-make it to your requirements. Whether, it is a slight modification, or complete customisation. We will partner with our devoted team of engineers and designers to cater to your specific needs.

Shipping Containers used as Urban Farms

Friday, August 26, 2016

Urban farming is a growing trend and is gaining popularity all over the world. Did you ever imagine farming taking place in a densely populated urban area? Is this the farm of the future? Is it a matter of “before you think outside the box, think inside of it?” Start-up Urban farms in the U.S. did just that. Daniel Kuenzi, an entrepreneur from Washington DC., is transforming derelict shipping containers into freight farms. Not only is he repurposing the surplus containers stacked in ports all over the world, but he is also giving momentum to fresh food grown locally. Let’s take a glimpse inside an Urban Farm and find out what the hype is all about.

Urban Farms – Their mission

According to the article posted in The Australian’s Business Review, The US. Food Tech Urban Farm exhibited the brussel sprouts nurtured and grown in recycled shipping containers at the Collison technology conference in Las Vegas. Caroline Katsiroubas of Freight Farms stated that;“Our mission is to create a more connected and sustainable food system.” “Everyone wants to be more, local, know where their food comes from and has a relationship with people growing their food.”

Urban farms offer freshly picked and reasonably priced vegetables and fruit. They bring the best produce to you in a used container that is highly engineered and equipped to allow crops to thrive and grow in your local community or just about anywhere.

Cultivating produce in recycled shipping containers. Where did the idea originate from?

Shipping containers are durable, versatile and stackable and can be relocated just about anywhere. Due to the abundance of unused shipping containers, it can be refurbished or recycled at a reasonable cost. As opposed to the traditional greenhouse construction, shipping containers gives you the flexibility to have a farm up and running in a shorter space of time. You can install and retrofit these containers within weeks rather waiting months or years it takes with its traditional counterpart.

Hydroponic method of cultivating crops:

Each of these farms uses the newest indoor agricultural techniques. These containers are installed with equipment to control carbon dioxide levels, temperature, nutrients and air flow in the water to nurture the crops.

The nutrients required by plants are water-fed through the artificial soil. The outcome is a remarkably higher yield in a shorter period than traditional production methods. According to Katsiroubes, it also uses 90 percent less water. Moreover, there is an application that allows container farms to be controlled and monitored from further afield.

These insulated shipping containers are modified to produce an optimum environment for nurturing and growing crops. In the future, with further advances can provide a container that is more energy efficient and ultimately become self-sufficient.

Restaurants use fresh, high-quality ingredients, ready to use. Urban Farmers can tap into the market and choose to grow crops that are in demand. They have the added advantage as the weather, climate and soil are not of concern.

The Many Uses of Different Size Shipping Containers

Thursday, July 28, 2016

Shipping containers are constructed to standard dimensions so that they can efficiently transport goods via trucks, trains and ships over long distances. The most frequently used size shipping containers are; the 40-foot container, the 20-foot container, and the 10-foot container. Each has their function when transporting cargo across the oceans. Likewise, they have unique benefits when they are re-purposed. The possibilities are endless; you can create many uses for the different size containers.

Here are a few suggestions:

10-Foot Containers

The 10-foot container is a small unit and is ideal when you lack space, but require the durability and mobility it offers. These are perfect for relocation and storage purposes. 10-foot shipping containers store the equivalent of a standard household’s items. They can easily accommodate furniture items. Due it’s compact size, they can very easily be modified and transformed into site sheds, small office spaces, in particular for those work in remote locations and whose workplace is not fixed. Do you need a designated work space away from the house without taking up too much of your backyard? A 10-foot container can be the solution to the problem. It can adequately accommodate a desk and chairs. It is a cosy, compact space to create a studio for an artist, or writer, providing the solitude to get the creative juices flowing.

20-Foot Containers

We are all aware of how versatile shipping containers are. The bigger the shipping container, the more creative you can be. Outdoor culture is prominent in New Zealand. This size container is ideal for creating an outdoor retreat, as it is mobile and one can install it with little effort. Therefore, suitable for the quintessential Kiwi bach or camping hut. A 20-foot shipping container can comfortably sleep a family of four. It is also ideal, for those who want to escape the hubbub of the city, and enjoy a weekend of surfing. A 20-foot recycled container can be modified into a ‘surf shack.' Skillfully using the space, to accommodate a kitchen, bathroom and bedroom. It has also been known to house a family, especially when you want to live in the middle of nowhere, as they can go anywhere because construction takes place offsite.

40-Foot Containers

Shipping containers are there for the taking, and lots of businesses are finding innovative ways of using these structures. 40-foot containers offer more opportunities to develop and modify due to their size. Shipping containers can be useful for almost any type of business. Creating offices, homes, mobile classrooms, etc. are growing in popularity. Many times stackable shipping containers are prominent, saving cost, reducing construction time and minimising your carbon footprint. More people are opting for living self-sufficiently and close to nature. Your off-grid home constructed of shipping containers can be installed, if you want to be nestled in the bush or on a hilltop.

The size, durability and versatility of the containers make it a valuable building initiative that is underutilised.

They are durable and maintained without much effort. You can design the interior and have all the modern features and quality fixtures in the interior of workforce housing.

  • 3.Stackable and Portable

Shipping containers were designed to transport cargo efficiently by truck, train, plane or ship. Containers are practical in remote areas as they are easily transportable.

Being stackable shipping containers are intrinsically more advantageous than traditional modular buildings. When space is limited, there’s no reason why your work camp can’t be two or more stories high, to accommodate a large workforce.

The plumbing and electricity are easily connected and ready for immediate use.

Used Container Grading

Friday, July 01, 2016

When deciding to invest in a used container, you will encounter grading acronyms that might not make much sense to you. It can all be confusing, as there is no clearly outlined grading system used internationally. In this article, we will endeavour to shed more light on grading and certification systems. The acronyms referred to are IICL, CW, WWT, CSC, ACEP, ISO and so forth. To make things easier, we grade our used containers as A, B, or C. What does all this mean? Here are the key acronyms and what it stands for, to help you make a more informed decision. 

  • IILC – Institute of International Container Lessors – An organisation of the largest container and chassis leasing companies throughout the world. The IILC provides repair standards, which is applicable for all repairs done to containers when off hired. IILC is the strictest criterion available for used containers.
  • CW -Cargo Worthy – Criterion that ensures that a container deemed cargo worthy is fit to carry cargo under TIR/UIC/CSC and complies with all standards in the original specifications. It signifies that the container has a valid CSC. You would need to get a third party container surveyor to carry out a physical inspection of the used container you want to send overseas.
  • WWT – Wind & Water Tight – It means exactly what the title says, “wind and water tight”. By way of explanation, it means that if you lock yourself inside the container, there should be no light shining through the roof or panels. It is important to note that it does not make reference to the standard of the understructure. A WWT container is usually not suitable for the transport of cargo; except when it clearly states that it meets the CSC. WWT is a frequently used term to classify used storage containers. In short, WWT plus CSC equals CW.
  • CSC – Convention for Safe Containers – Is in existence since 1972, to foster and maintain a highly efficient level of safety of human life in the handling and shipment of containers by implementing commonly acceptable evaluation procedures and relevant strength conditions. It helped enable the international transport of containers by providing uniform international safety regulations.
  • ACEP – Approve Continuous Examination Program – quality inspection programs set up by owners of containers to supervise the condition and maintenance of their containers. Considering that a unit is monitored under ACEP; it is exempted from undergoing the periodic re-inspection. Departure from the program under which the container was originally built and maintained, in the event of a sale means that containers will be required to be inspected under CSC so that it can be approved for shipping and to ensure an approval limited in time.

As previously mentioned, when referring to grading standards, it is crucial to bear in mind that companies have their internal classification system, as opposed to an international standard for purchasing containers. That does not imply that that two companies using Grading terms A, B, or C, necessarily mean the same for both. The grading tends to apply to the cosmetics of the container rather than structural quality, and hence are not international grading standards. It is imperative that you ask for an explicit definition of the grading system. In an attempt to give readers more insight into what they can expect, we produced a table of the most common classifications with different classification categories:



Especially when purchasing a container you have to think carefully and clearly define your requirements and desires. The three fundamental questions you almost certainly want to ask yourself are: 

  • 1. Do I require/want a container for cargo?
  • 2. Do I require/want a container for storage?
  • 3. How significant are cosmetics to me?

These are the crucial questions you need an answer to when looking to buy a container. You can make more informed choices and invest in the appropriately certified container as per your requirements. Take heed; there are many dodgy companies out there. Do not be reticent to do your homework and ask for references. In conclusion; it is of paramount importance that you verify that you are dealing with a reputable company.

Do not hesitate to contact our expert team for further information about grading and certification of used containers.
