When planning an aircraft hangar, one of the first questions serious buyers ask is:
How wide can it actually be without interior columns?
Clear span width directly impacts aircraft movement, door sizing, long term flexibility, and overall project cost. Getting this right at the beginning avoids structural limitations later.
Let’s break it down.
🏗️ What Does “Clear Span” Actually Mean?
A clear span hangar means the building has no interior columns or support posts interrupting the open floor space. The structural framing carries the load from sidewall to sidewall, creating an uninterrupted usable space.
For aircraft storage, that matters.
Taxiing inside. Turning wings. Future aircraft upgrades. All of that depends on open interior width.
📏 Typical Clear Span Ranges for Aircraft Hangars
Most pre engineered steel aircraft hangars fall into these general ranges:
Yes, clear spans can exceed 200 feet with proper engineering. But as the width increases, the structural demands increase significantly. Span is never just about how wide you want to go. It is about wind load, exposure category, roof pitch, and door configuration.
⚖️ Structural Tradeoffs as Width Increases
As the span grows, so do structural forces.
Here is what changes:
Primary frames become deeper and heavier
Steel weight per square foot increases
Deflection control becomes more critical
Connection design becomes more robust
In high wind regions like Florida or coastal Texas, loads may drive design more than width alone.
A 120 foot clear span in a low wind inland region is engineered differently than a 120 foot span near the coast.
This is why hangars should never be quoted purely by square footage without load assumptions clearly defined.
🚪 How Hangar Doors Impact Clear Span Design
The door opening is often the true driver of span design.
If you want a 100 foot wide door opening, the structural frame must accommodate that clear opening width.
Door type also matters:
The larger the door opening, the more reinforcement is required in the header and jamb framing. In many cases, the door drives the structural cost more than the building width itself.
🌎 Location Always Matters
Wind load, snow load, and seismic requirements can dramatically affect practical clear span limits.
A 150-foot clear span in Arizona is engineered differently than a 150-foot span in South Florida. This is why engineered steel buildings outperform generic “kit” pricing models.
The span is not just a number. It is a structural calculation tied to real-world conditions.
🚀 So How Wide Should Your Hangar Be?
Instead of asking “What is the maximum span possible?”
The better question is:
What span gives me operational freedom without unnecessary structural cost?
That answer depends on:
Aircraft type
Door width requirements
Location and loads
Long-term growth plans
When engineered correctly, clear-span hangars provide flexibility, safety, and long-term value.
