Step 1
Less material used
Answer
One reason for the use of tubular steel in the roof structure of modern sport arenas is that it requires less material compared to traditional framing methods. This reduction in material not only decreases construction costs but also minimizes the overall environmental impact of the building.
Step 2
Lighter structure weight
Answer
Another important reason is the lighter weight of tubular steel. This characteristic allows for a greater strength-to-weight ratio, which enables longer spans free of internal supports. This flexibility in design creates more open and versatile spaces within the arenas, making them suitable for a variety of events.
