On a wonderful 20-degree summers day, Grafo-Therm applied at 1.5mm (approx.) is fully dry within 10 hours. During the cold winter months when the Grafo-Therm product is applied to steel containers or similar single skin ceilings, it will take up to two weeks to fully cure without any help.
The only way to speed up the drying time of the Grafo-Therm is to apply heat. Our mobile team can provide the equipment to assist with drying the area on the day they are treated* or you can install your own heaters for approx. 72 hours**.
Without applying heat to the area, you may find that the Grafo-Therm drips from the ceiling. If this does happen, you need to apply heat.
Small 2500W fan heaters can be purchased directly from us at £65.00 +VAT (inc. P&P).

*Additional £30.00 per 20ft container or priced according to the quantity of containers/size of the area.

We supply a massive range of container modification options and accessories, so much so that it can be quite daunting if you’re unfamiliar in the world of shipping containers. So, we thought we would narrow down the options for you if you are looking for a simple, dry storage container that will last. Shipping containers are made from Corten steel, often referred to as weathering steel because it is designed to form a rust-like appearance when exposed to the weather. The shipping and storage containers that we supply leave our nationwide container depots fully wind and watertight. Whilst they are ready to use on arrival, there are a few products that will help to extend the life and value of your container;
Grafo-Therm anti-condensation coating is the most cost-effective long-term solution to protect your shipping container from condensation and corrosion. This product offers protection to both your container and the items you are storing, by doing so it prevents mould and rust. Grafo-Therm is very popular amongst our self-storage clients as it offers extra protection for their customers who store valuables in the containers and also prolongs the life of their shipping containers. With prices starting from £150.00, Grafo-Therm is a cost effective option to protect your shipping container. Find out how it works here >>
The paint we use on shipping containers is marine grade container paint. It is designed to protect the Corten steel containers when they are being used in harsh marine environments. When using the container for domestic or commercial storage, having an extra layer of this hard-wearing paint will provide a barrier between the steel and the ever-changing Great British weather. It will also give your container a fresh, clean finish.
The shipping container paint colour options are all based on the standard RAL colour chart. We offer a few different standards of painting from a basic full blow over to a single RAL colour to more in depth options which can include removing decals or patches before painting. Ask our team for further details.
Fitted High Security Lockboxes and CISA Padlocks
One of the main reasons shipping containers are used for storage is because they are secure. The robust steel units are equipped with a set of double cargo doors which are closed by up to four locking rods. To ensure the container can only be opened by the owners, we recommend having a fitted high security steel lockbox fitted to the cargo doors. The lockbox is a steel shroud which is fitted houses a padlock. Teamed with a heavy duty, cut and pick resistant CISA padlock, this set will help to keep your valuables safe.
All of the options detailed above can be done in depot or at your site. We hope that this helps you with your container purchase and prolonging the life of you unit, if there are any further accessories that you are considering, such as shelving or access ramps, you can find out more on our container accessories page or by asking our team.
I need secure storage for my tools at work but we only have a small space available, can you help? We're asked this a lot at 3J Services Ltd!
Our custom built containers can be manufactured to any size. With a team of skilled steel fabricators to hand, 3J Services can create a range of secure stores, office space, accommodation units and much more. We have recently built some smaller 5ft x 6ft tool store containers which have been equipped with single personnel doors, lifting lugs, internal lining with shelving and hooks for tools and equipment. These units are cheap and easy to transport so can be distributed easily to sites around the UK. Other options may be 5ft x 8ft cut down containers, 6ft x 6ft new storage containers or bespoke custom-built units ranging from 4ft x 4ft up!
Container cargo doors are quite heavy but easy to operate once you’ve got the knack! Each door is usually equipped with two steel locking rods that run from the top to the bottom of the door. At each end of the locking rod you’ll see a cam and keeper which need to be turned to release the door. To do this you firstly need to move the custom catches up from the handlebar, starting with the right hand door.
Next, you need to lift and pull the door handles out slightly to allow the cams to be released. Pull the inner door handle out a bit further and then the outer handle, then pull them together to release the door in full.
Voila! Your container is open!
To close the container doors, you just need to do the above process, backwards. Start with the left hand door first , push the door back into place and twist the handles to secure the cams and keepers. Once the cam and keepers are engaged, fully turn the handles until the door is closed.
If you do have any problems with opening and closing your container, check that the ground and container are completely flat. If the ground is not flat it will cause the container to twist and your doors will not close which is known as “racking”. You can find out more about racked cargo doors and how to fix them on our blog.
If you’re struggling to close your newly delivered or loaded shipping container, the chances are the cargo doors have racked. This means that the doors aren’t aligned properly because the container isn’t sitting flat, or one end has dipped when it’s been loaded.
If your container doors wont shut, it’s likely that the base isn’t completely flat causing the front of the container to slope in one direction whilst the rear slopes in another. This causes the container to twist making the door opening form a diamond shape instead of being rectangular, preventing the locking bars from operating. Racked containers are a common problem but very easy to solve.
To prevent your cargo doors from racking, ensure that the grounds are level prior to the arrival of your delivery driver. We recommend that containers aren’t sited directly onto grass or soft surfaces as the unit will sink. You should site your container on something sturdy like a hardcore or concrete base, concrete slabs or timber railway sleepers. Your container only needs to be supported in the four corners, even when loaded. Always make sure to check the doors open and close properly before the delivery driver unhooks his chains and packs up to leave site.
To solve the problem of racked cargo doors, firstly you need to shut the doors as best you can then have a look at the top and bottom to see where they meet or overlap – you may need to stand a few metres back to see this. One door will be sitting lower than the other so this is the side that needs to be altered. When you lift the lower side up, the cargo doors and opening will return to their rectangular shape allowing the doors to close properly. The aim is to lift the lower corner and pack it with steel or timber shims to hold it in the correct position. If this corner is difficult to access or lift, you can lift the diagonally opposite corner at the front wall of the container, it will have the same effect. The container will likely only need to be raised 10mm to 30mm.

Roller shutter doors are an excellent option for shipping container access. They are strong, watertight and secure. The standard roller shutter doors we supply are made from galvanised steel which can be painted to any RAL colour or branded with company logos.
Our roller shutters are made to order and can be any height to suit the container project and up to 10 metres wide! If you need a large, unobstructed space to access the container, to serve food, drinks or merch from, or just need some extra security, a roller shutter door could work for you.
These bespoke steel roller shutters have been used in many of our container conversions including container bars and food stalls, secure stores, container ticket offices, turnstile containers, pop up retail stands, multistores, test facility shipping containers and more.
Contact the team today to discuss your container conversion options.
We are asked regularly for a price of the smallest container we supply, as most people will assume less steel, less container, less money! But oddly, this isn’t the case.
20ft and 40ft long shipping containers in used condition, are the most common size of shipping container in the UK market. Shipping Containers are built to perform like Lego blocks, making them easy to transport and stack so, by retaining these sizes, it allows them to be handled and moved by a variety of different methods on the road, rail and at sea.
Shipping containers are extremely versatile and robust structures which are easy to transport, site and stack making them perfect for use within healthcare. Now, many hospitals in the UK have been using accommodation and storage containers as isolation pods for people with suspected Coronavirus.
Units have been sited outside of hospital accident and emergency departments to provide extra facilities for the arrival of new patients, to support the efforts to prevent the spread of Coronavirus. The units have phones installed which call directly through to the A&E department so anyone who is showing signs of carrying Coronavirus can enter the unit and call the team within A&E directly. By doing this, the hospitals can isolate patients potentially carrying Coronavirus away from other vulnerable people within the busy emergency departments.
Using shipping containers at hospitals and healthcare facilities is an ideal solution when additional space is needed quickly. Standard storage containers or accommodation units can be delivered within a matter of days or we can convert containers for handling specific situations which takes only a few weeks. We will work with you to design and produce the required space out of the steel containers or custom-built units, carrying out the conversion in house and delivering directly to site. Our containers can be adapted to become mobile health clinics and medical centres, pop-up emergency shelters, isolation pods, secure storage or container assessment units.
The size of the container delivery vehicles can be up to 65ft long, 10ft wide and 14ft high. The space needed to off-load the container is much larger. Hi-ab vehicles have to use “legs” at each side of the vehicle, front and back to provide balance whilst moving the large weight of the container. The legs can extend up to 6ft on each side bringing the overall width of the unit up to 26ft maximum. Should your site not have this much space to play with, let us know and we will take a look for you.
The vehicle, loaded with the container, would usually drive into site and off-load the container parallel to the vehicle bed. The haulier will then turn the vehicle around and drive out. We understand that not many sites will have the space to accommodate a 65ft vehicle turning around, so we do ask that you check with us and send some site photos.
Shipping containers, secure stores, accommodation units and converted containers should always be sited onto hard standing, level ground. If the container is going to be sited permanently it may be worth the investment of a full concrete pad, otherwise the more cost-effective alternative would be to put concrete slabs down to meet the four corners of the container. What we are trying to avoid by doing this is the container sinking into the ground or twisting/becoming uneven. If the container isn’t on a solid, level base, the unit may have problems with opening and closing the doors. This is known as “racking” and can be easily avoided if the grounds are checked and properly prepared before delivery.
Timber railway sleepers are also commonly used to provide a level ground for the units to sit on.
We are more than happy to give you some guidance of how to prepare the grounds for your container so if you have any concerns please ask.
You will have seen hundreds of shipping containers on the move along motorways during your travels, you might have even caught sight of a container vessel whilst on a ferry journey! But how could one of these giant storage boxes be delivered to your site?
3J Services Ltd work with a group of specially selected, fully qualified container hauliers across the UK. Our trusted teams operate various types of vehicles, suited to deliver containers and cabins onto all sorts of sites, mainly using Hi-Abs to off-load.
Our most common method of delivering shipping containers and cabins to locations around the UK is by using a Hi-Ab vehicle. These vehicles are usually a flatbed or skeletal trailer, equipped with a hydraulic crane (The Hi-Ab) which is situated behind the drivers’ cab. The craned lorries can range from 20ft to 55ft in length. The crane is operated by the driver who will attach chains to the hook of the hi-ab and the four top corner castings of the container. He then uses a control pad lift to operate the Hi-Ab, off-load and position the container.
How can I move my shipping container once it’s on site?
Shipping containers can weigh up to 4T when empty and 28T fully loaded! They are bulky units but do have some handy options if you need to shuffle them around on site. Containers are equipped with extremely strong, load bearing corner posts with corner castings at the top and bottom. The standard way to off-load and move a container is by hooking chains through the corner castings and lifting the unit using a hi-ab mounted vehicle. This can be done at the top and bottom castings.
Another way to move a container is by the forklift pockets. 20ft standard shipping containers usually have forklift pockets at the side of the unit and at either short end. We recommend using 8ft long forks with an 8ft wide split.
