Top Commercial Manufacturers & Dealers

The first thing to know about storage container manufacturers and dealers is that some mostly focus on commercial products while others cater more to a residential market. 

Commercial storage containers are typically made of high-grade heavy-duty steel, are wind-and-water tight. They also look more industrial compared to residential portable storage containers. Note that there are both manufacturers (who make portable storage containers) and dealers (who just sell storage containers). Some companies also do both! Take a look at our list of top portable storage container manufacturers and dealers for commercial needs.

1. Universal Storage

Universal Storage is a portable storage container manufacturer. They have won international awards for the “#1 self-storage container.” While they are an ideal commercial solution, they can also help residential customers as well. They provide several portable storage products (keep in mind that Universal Storage’s products have trademarked names):

  • Z-Box: also known as self-storage portable containers. These can be stacked 3 high and can include flexible interior and exterior customizations. Note that they are not corrugated, which make them ideal for printing brand logos on the outside.

Residential portable storage containers are typically designed for self-storage and moving purposes. They typically appear less industrial compared to commercial storage containers and usually come in smaller dimensions.

What to Look for in a Storage Container Manufacturer

Features to look for in a storage container manufacturer will be different depending on what you are using the portable storage container for. For instance, if you are using the container for stationary/on-site residential OR commercial storage, you will look for certain features. If you are using the portable container for moving purposes, you will look for other features. Consider these lists of features to look for when using a portable storage container for moving vs. non-moving purposes. 

Non-Moving Purposes

If you need a portable storage container for non-moving purposes, your container will likely be stationary or on-site (rather than transported) while in use. In terms of non-moving purposes, here are some key features to look for:

1. Exterior

For non-moving portable storage containers, the exterior is what keeps the storage container durable, weather-proof, resistant to damage, and able to support weight. You want a storage container with the sturdiest metal possible in order to provide the best product in the industry. 

Although steel and aluminum are used for siding, we recommend looking for containers with steel rather than aluminum exteriors. Steel is stronger (although heavier), more durable, and will last longer. The only downside to steel is that it can rust and it is heavier than aluminum. However, most storage containers today use steel due to its reliability and durability.

2. Walls, Roof, and Floors

Different portable storage container manufacturers will use different materials for their walls, roofs, and floors.

  • Walls: Some walls will be corrugated and some will not be. Corrugation can impact the appearance of the container as it looks more “industrial.” Plus, if you are looking to print your company’s logo on the exterior, it will be harder to do so and make it look clean on corrugated walls. Also note what material the walls are made of. Plastic can bend and corrode easily while steel and aluminum will be more reliable.

  • Roof: The roof needs to be sturdy and durable. Especially if you are planning to stack containers, you need a roof that can support weight. Again, steel is the best for this. If you are keeping your containers outdoors (you likely will be), you need the roof to withstand rain water, snow, ice, heat, and more. Note that corrugated roofing can cause water to pool up and damage the roof.
  • Floors: You need a thick, sturdy floor to support the weight of cargo inside. Beware of anything that can easily bend or get damaged. Most storage container floors are made of plywood but steel flooring is even better.
3. Doors

Different manufacturers will likely have different types of doors. You will likely come across the two most common types of doors when comparing manufacturers – swing-out and roll-up doors.

  • Swing-out: Swing-out doors work like regular doors. They are more common for non-moving portable storage containers. Most containers have two doors that close together and swing out horizontally. Others will have a single swing-out door. Most containers with swing-out doors will have one set of doors on one side of the container, but some may have two sets.

  • Roll-up: Roll-up doors work like a garage door. They roll up from the ground up. This can be convenient because they don’t require extra room around the door to open them, whereas swing-out doors do need extra “swing” space. Therefore, roll-up doors are great for containers that will be in tight spaces. However, they tend to be less secure and watertight than swing-out doors, especially when used for commercial purposes.

4. Stackability

Do you plan to stack your containers? This can be a great idea for commercial needs. It can help you save room and fit more containers at your location. If you do plan to stack, you must look into your container’s materials to ensure each can support weight placed on top. Most containers made of steel can support the weight of 2 containers stacked on top. Make sure to ask the container manufacturer questions like:

  • What material is the roof made of?
  • How much weight can each container support on top?
  • What equipment is needed to stack your containers?

Oftentimes you will need a forklift to stack containers, so keep this in mind!

5. Rust Prevention

Rust can be an issue for steel storage containers. But luckily, many manufacturers use preventative measures to help the container stay rust-free. Some common methods for rust prevention are:

  • Finishing
  • Powder coating 
  • Galvanization
  • Rust grip

Galvanized metal and rust grip are the most reliable ways to prevent rust. However, they are pricier which may drive the container prices up. On the other hand, finishing and powder coating are less reliable but more cost-efficient. Note that painting storage containers may take away the appearance of rust, but does not get rid of it!

6. Container Sizes & Weights

You likely have some sizes and dimensions in mind if you are looking to buy from a portable storage container manufacturer. But in case you don’t, look into conex box dimensions here. Most storage container manufacturers will carry “traditional” sizes (categorized by length), such as:

20-foot and 40-foot containers tend to be the best for commercial needs. Many suppliers will carry untraditional lengths as well. Note that most rectangular portable storage containers are 8 feet wide and 8-8.5 feet tall. Simply ask the manufacturer what sizes and dimensions they carry.

When it comes to weight, there is the weight of the empty container (“empty weight”) and the max weight (“capacity weight”). You want to be sure your trucks can support both the empty weight and the capacity weight. Note that the amount of weight the container can support depends on its size and material. Steel containers can hold as much as 25,000-70,000 lbs. at capacity. But containers made of other materials will likely have a much lesser capacity.

7. Shipping and Assembly

It’s important to find out how portable storage container manufacturers handle shipping products to you. For instance, what is the shipping charge? How many containers can the manufacturer send at a time? Then, you will want to find out how you plan to assemble them once they arrive.

Manufacturers may ship portable storage containers pre-assembled or in parts. Do you have a team, tools and equipment to assemble container parts? You will likely need forklifts or a boom crane to get the job done. Not to mention, you should know how to assemble the container before it arrives. If you don't have any assembly experience, you can ask the manufacturer if they offer assisted assembly at your location.

Moving Purposes

When using a portable storage container for moving purposes, you will want to make sure the container is ready to handle transportation conditions. You want to look for something sturdy that can withstand being transported via truck and still protect your belongings inside. Take a look at these features to look for in a portable storage container for moving purposes.

1. Exterior and framing

The material used for the exterior of the storage container is crucial. The exterior is what keeps the storage container durable, weather-proof, resistant to damage, and able to support weight. 

Make sure to look for a portable container that has high-grade steel framing and metal exterior (including the roof). The walls may be a different metal than steel, such as aluminum. But containers with steel framing will make for the best moving experience possible.

2. Walls and Floors

  • Walls: For moving containers, it does not really matter whether or not the container has corrugated or un-corrugated walls. Since you are only renting the container, the appearance does not matter. However, moving containers tend to be un-corrugated.
  • Floors: Plywood is the best material for a moving storage container. This is because you will be moving many items in and out of the container, and it is easy to replace if damaged. If you scuff up the plywood, it will not matter.
3. Doors

When using a portable storage container for moving purposes, it’s best to look for a container with roll-up doors. This is because compared to swing out doors, roll-up doors will help you to save space. They will also help you to enter and exit the container easier while loading and unloading during your move. Luckily, most moving containers come equipped with roll-up doors.

4. Durability

Although you will not be using the storage container for a long time, you will want to find containers that are durable and weather-proof so your belongings stay secure. For instance, you will want the moving container to include:

  • Wind-and-water tight security
  • Galvanized steel framing (to prevent rust)
  • Tie-down rings (to hold items in place)
  • Smooth walls inside (to prevent “dings” and dents)

These items will help to keep your items intact during the move.

5. Sizes

Portable storage containers for moving purposes will be a bit smaller than commercial containers. Some standard sizes for moving containers include:

  • 7-foot
  • 10-foot
  • 12-foot
  • 16-foot
  • 20-foot 

A good rule of thumb is to designate about 75 square feet of storage space for each room of your house/apartment when moving. Therefore, 7-foot and 10-foot containers will be the best for moving studios and 1 bedroom apartments. 12-foot, 16-foot, and 20-foot containers will be your best bet if you are moving 2 rooms or more. 

6. Delivery and Transportation 

When finding a portable storage container to move, you will want to ask questions about how delivery works as well as how the container will be transported during the move. For instance, 

  • Will the supplier drop off and pick up the container at your location? 
  • Do you have to pick up and drop off on your own? 
  • What are the delivery charges?
  • How long in advance should you reserve the moving container?
  • What preparations at your location do you need to make?
  • Will you be in charge of transportation or does the supplier handle this for you?
  • Are there any materials you will need to help with the move?

Make sure you are 100% prepared for the delivery and move to ensure the smoothest, most secure process as possible.
