How much space does a steel hangar require?

Hey there! I'm a supplier of steel hangars, and one question I get asked a lot is, "How much space does a steel hangar require?" Well, it's not a one - size - fits - all answer, and in this blog, I'll break down the factors that determine the space needs of a steel hangar.

1. Purpose of the Hangar

The first thing that affects the space requirements is what you're going to use the hangar for. There are different types of steel hangars, like the Prefabricated Steel Structure Hangar, the Portal Steel Structure Hangar, and the Steel Structure Aircraft Maintenance Depot.

Aircraft Storage

If you're using the hangar to store aircraft, the size of the planes is the most obvious factor. Small single - engine planes are a piece of cake. They usually need a hangar with a width of around 20 - 30 feet and a length of 30 - 40 feet. That gives enough room to open the doors, walk around the plane, and do some basic maintenance.

But if you're dealing with larger commercial jets or private jets, things get a lot bigger. A medium - sized private jet might need a hangar that's 60 - 80 feet wide and 80 - 100 feet long. And for the big boys, like large commercial airliners, you're looking at hangars that can be hundreds of feet wide and long. You also need to factor in the height. Planes have tails that stick up, so you need a hangar tall enough to accommodate them without hitting the roof.

Aircraft Maintenance

For an aircraft maintenance hangar, like the Steel Structure Aircraft Maintenance Depot, you need even more space. In addition to the space for the plane itself, you need room for all the tools, equipment, and workstations. Mechanics need to be able to access every part of the plane easily. That means having extra space around the sides and at the ends of the plane. You might need a hangar that's 20 - 30% larger than a storage - only hangar for the same size plane.

You also need space for things like hydraulic lifts, scaffolding, and diagnostic equipment. And don't forget about areas for storing spare parts. All these things add up, and you end up with a much larger hangar.

Other Uses

Steel hangars aren't just for planes. They can be used for storing other large equipment, like construction machinery or boats. If you're using it for construction equipment, you need to consider the size of the biggest piece of machinery. Bulldozers, cranes, and excavators can be pretty large, so you'll need a hangar with enough width and length to fit them comfortably.

2. Operational Space

It's not just about the size of the stuff you're putting in the hangar. You also need to think about how people are going to operate inside.

Doorways and Access

You need to have enough space around the doorways to open and close the doors easily. If the hangar doors are too close to other objects or the walls, it can be difficult to get things in and out. A good rule of thumb is to have at least 5 - 10 feet of clear space on either side of the door. This allows for easy maneuvering of planes or equipment as they enter and exit the hangar.

Movement Inside

People need to be able to move around freely inside the hangar. That means having enough aisle space. In a maintenance hangar, you might need aisles that are 10 - 15 feet wide to allow for the movement of equipment and people. In a storage hangar, 5 - 10 feet might be sufficient.

3. Future Expansion

When planning the space for a steel hangar, it's always a good idea to think about the future. You might start with a small number of planes or pieces of equipment, but what if you want to expand your operation later?

If you think there's a chance you'll need to add more planes or larger equipment in the future, it's better to build a hangar that's a bit larger than you currently need. It's a lot cheaper to build a bigger hangar from the start than to try to add on to an existing one later.

4. Local Regulations

Local building codes and regulations can also affect the space requirements for a steel hangar.

Setbacks

Many areas have setback requirements. That means you need to leave a certain amount of space between the hangar and the property lines. Setbacks can range from a few feet to several dozen feet, depending on the location. This reduces the amount of usable space on your property and can affect the size of the hangar you can build.

Height Restrictions

Some areas have height restrictions for buildings, including hangars. If you're building near an airport or in a residential area, there might be limits on how tall your hangar can be. This can be a problem if you're trying to accommodate tall planes or equipment.

5. Safety Requirements

Safety is always a top priority, and it can impact the space requirements of a steel hangar.

Fire Safety

Fire safety regulations often require a certain amount of clear space inside the hangar. You need to have fire - resistant barriers between different areas, and there need to be clear paths for evacuation. This might mean having wider aisles or leaving more space between stored items.

Structural Integrity

The structure of the hangar itself needs to be safe. That means having enough space for the support columns and beams. If the hangar is too crowded, it can put extra stress on the structure, which can lead to safety issues.

Conclusion

So, as you can see, there's no simple answer to the question of how much space a steel hangar requires. It depends on the purpose of the hangar, the size of the objects you're storing or working on, the operational needs, future expansion plans, local regulations, and safety requirements.
