Shipping Container FAQs

1. What is a shipping container?

A shipping container is a steel container built to a worldwide compatible ISO specification allowing it to be shipped and transported by means of cranes, ships and haulage to any worldwide destination. The shipping containers are robust and can hold up to 20 to 35 tonnes in cargo weight.

2. What is a storage container?

The storage container was designed for more as called – a storage container (Non-ISO) they are not built for the shipping industry and are not normally as robust as a conventional shipping container yet they provide perfect storage for all the same needs as a conventional shipping container. They can be built to any transportable size ranging from as small as 6ft to 40ft and are fully secure and lockable.

3. How heavy is a shipping container?

Our shipping containers for sale vary subject to size as do the storage containers yet they range (empty) from two tonne to five tonne.

Weight1.5 ton (1450kg)2.2 ton (2230kg)2.8 ton (2840kg)3.3 ton (3950kg)

4. What should I buy a shipping or storage container for and why new or used?

The purchase is based both on your budget and the intended use of the unit. Buying any product new gives you a prolonged life span and peace of mind that it will be problem free. Buying used is in some ways the same except it is already a number of years old and will have wear and tear.

5. What size is a shipping container

Shipping containers must conform to ISO dimensions the most common sizes are 20ft (6.06m) x 8ft (2.59m) and 40ft (12.2m) x 8ft (2.59m) yet there are variations for the type of unit IE high-cube containers which are taller at 9.5ft (2.89m) high.

6. Are shipping containers and storage containers weather proof?

Shipping containers have fully welded seams and have full rubber doors seal to the double doors. Storage containers have full welded seams and the doors are manufactured in ways that do not allow rain water getting through the joints to the interior of the door area.

7. Are shipping containers secure?

All measures are taken to make them as secure as possible. All shipping containers new and used and most storage containers have a lockbox fitted to the double door and are referred to as a lock box, cowl or a lock protector. They help to prevent your padlocks being tampered with by covering it.

8. How does the locking device work?

A lock box is not actually a lock so do not be confused when you are told it has a lock box fitted as you will still need a lock unless it is a fitting with a permanent built in lock. A lock box is a steel fabricated 5 to 6mm box that is welded or bolted to the double doors to protect your lock from being damaged or tampered with. The most common lock is called a “Cisa” lock but there are other brand names of lock that do the same job please see our Video on lock products for more information.

9. How to open & close a shipping container door?

On most shipping or storage containers it is the right-hand door that opens first. On a shipping container, there are four locking bars with handles that are held in place by a customs catch. Turn these catches away from the locking bar and hold each of the two handles then give a lift upwards to release them from the retainer lip and move both handles from your right to the left. The left-hand door is the same process yet you turn the handles from right to the left. When closing the doors if both are open the left side door will close first then the right with the locking handles turning in opposite direction to close. Here is a handy video on how to do that.

10. Do shipping containers get condensation?

Condensation is present in most shipping and storage containers in the UK due to our damp weather, every effort is made to minimise this. New build shipping and storage containers are fitted with extra vents to allow better air flow and keep condensation to a minimum. There are products to combat this from Absorba poles to Grafo products or the full fitting of thermal blankets.

11. Are there any other methods used for insulating my shipping or storage container against condensation?

Yes, we have a full lining out service that consists of building a wooden framework to the interior and fully insulating between all the framework with a thermal insulation and then over boarding with various types of wall board subject to your budget ranging from basic shuttering ply to marine smooth faced plyboard.

12. Does my shipping container or storage container need painting?

New shipping containers shipped once to the UK come in limited colours mainly blues, greens, greys or browns yet for an additional fee we can colour change them for you to the colour that you require. New built storage containers manufactured here in the UK can be sprayed in a single colour of choice as it is included in the purchase cost. Both used shipping containers and storage containers are in the original colour or the colour they were sprayed previously yet again they can be sprayed to a RAL or BS colour of choice excluding metallic or pantone colours. Please refer to our full colour chart for more information.

13. How long does a shipping or storage container last?

A shipping container or storage container needs to be maintained periodically and if carried out then they should last for upwards of 20 to 30 years. We recommend that you oil and grease any door parts and oil locks and mechanisms. Check for signs of surface rust, especially on the roof and touch them up with paint if required

We can give you the base pad sizes for the container in question and then you can even up the ground by using paving flags or railway sleepers as which is the most common method. These items placed on the four corners of the unit or in extreme cases we can supply and fit adjustable jacklegs to the container that are adjusted on each of the four corners to the lay of the land. The Hiab driver will normally do this for you.

Portable Cabins FAQs

1. What is a portable site office or cabin?

Portable is a common term for a Cabin that can be transported from site to site, it may be totally different from an Anti-vandal office as they are also Portable and can be also moved from site to site.

2. What is the difference between a portable office and an Anti vandal office?

People regard the portable office as being a more up market as some of them are purpose built with a sleeker finish and are more aesthetically pleasing designs with a flat panel robust steel finish or plastisol coated steel finish yet they are secure with both steel shutters or strong mesh guards. These steel and cladded type units were produced and have in recent years replaced the old timber and texture finished wooden cabin. Anti-vandal units are still used for the exact same purpose and yet again are portable so people do also ask for an Anti vandal portable office.
Anti vandal cabins are designed to provide a longer lasting alternative with more detailed security in mind hence why they have a solid steel construction with heavy steel access doors and steel protective window shutters. They became very popular in the construction industry to prevent both damage by vandals and also break in and theft of goods from inside and are the most popular with all customers due to ever increasing crime in most areas so they are again a safe option for the security aspect.

3. What is a plastisol Portable office?

A plastisol office is named purely from one of the products used in the building of the cabin and that is a plastic coated galvanised steel sheet. There are mainly two types used in the construction with the old method being a plastisol coated galvanised steel sheet being bonded to a plyboard so that outside of the cabin has a steel finish and is also rust proof. The second method is again similar except the Plastic coated galvanised sheet is bonded to a polystyrene or foam type block. These sheets are fixed in to the structure framework of the cabin being built to form the walls

4. What is a modular building?

Modular buildings are sections of prefabricated units that can consist of any number of sections joined together on site in single story or even multi story structures that have many big scale uses for instance School classrooms, Multi office complexes. The interiors again can range from open plan class rooms to mixed offices with toilet and kitchen facilities. Some councils are having them as temporary houses due to housing shortages.

5. Are all portable cabin units made secure?

The doors on all of our used  Portable Cabins and Anti vandal cabins have various styles of built in dead locks or sash type 5 lever locks and we supply a minimum of two keys per lock . The steel windows guards have spring loaded shoots bolts or spigot bolts that are both operated and locked from the interior. You will also find that most units have anti jemmy devices fitted to them to resist forced entry on the doors and steel window guards.

6. What Is a Jackleg portable site office?

A jackleg cabin can be a portable or anti vandal office with two jacklegs on each side. These jacklegs are now becoming obsolete on a lot of the modern built units and are fitted on request as an extra option on new build units. The purpose of them was to enable a Cabin to be put on uneven ground as you could adjust the legs to suite the ground and level the cabin. They were also used for cabins being stacked as the tops of the jacklegs had bolt together holes in them. Most cabins sold now have the alternative secure stacking points on the four corner posts on a steel unit.

13. Can I stack or join these used portable or anti vandal cabins together.?

Yes, we do have compatible units that will stack on top of each other although an external staircase would be required. Please see our accessories page for staircase costs + set up costs. Linking portable cabins side by side is achieved by each unit having two central doorways. They have two steel removable access doors with one of them on each unit being temporarily removed for the link up. Once the units are sat together side by side it forms a walkway through the centre of each unit. You can also have internal partitions fitted to form a corridor. The outside of each doorway is the temporarily sealed to stop any water from leaking in to the unit. The units at any time can then be split in to single units again and the removed access door refitted once they are no longer required on that project, hence becoming a single portable cabin again. Please note that all double stacked or linked units should have suitable ground to withstand weight loads so if you are in any doubt then please contact a member of our sales team for advice prior to placing your order.

14. Do you sell new bespoke portable cabins or anti vandal cabins?

Yes, we can build to any bespoke specification that you have in mind. If you give us the brief details of your requirements we shall then produce a CAD drawing of the cabin and forward it to yourself with all costs and if you wish to make any alterations, we shall alter the drawing and amend any difference in costs. Bespoke new builds can be built to suit any environment that even allows you to take away the rugged security aspect to give them a conventional building effect with the fitting of superior exterior cladding and timber finishing.
Certain fast food chains have bespoke sectional buildings in use that actually look like brick building yet it is a cladding finish.

15. Do you hire portable cabins or Anti vandal units?

Yes, we hire any of our units that you see on our website so please feel free to discuss this with a member of our sales team.

16. Do I need planning permission for my chosen Portable cabin?

The unit is deemed as a temporary portable unit so provided it is not on public property then you would require the consent of the landlord. Yet we say to all our potential customers that as different councils and areas of the country have different views then do not assume being a portable unit that you do not require planning permission so it is in your interest to seek local advice.
