More On Clear Span Structures
‘Clear Span’ is an architectural term to describe the distance between the two inside surfaces of the span supports; the distance that is unsupported, if you will.
If you have need in your building design for a wide space that is clear of posts and beams, then a clear span structure is the choice for you. A clear span design is one that does not have supporting pillars such as those found in pole buildings. A clear span building offers the most usable space and is ideally suited to factories and warehouses where vehicles such as fork lift trucks are used within the building.
The most common type of single-story building above 10m (30’) span is the steel ‘portal framed’ building; applications of portal frame buildings include: factories, warehouses, aircraft hangars, schools, gymnasiums & sports centers etc.
Clear Span is used for a space where a straight wall column and beam structure can be built. This building design offers an unobstructed and open space for any of your needs.
Clear span structures work best for a space from 32 to 82 feet in width without beams or posts. A pre-engineered aluminum structure is preferred and is as durable and cost-effective as steel. The most commonly requested aluminum-framed building sizes are:
- 32 and 50 feet wide
- 66 and 82 feet wide
- Length for these sizes are unlimited in 5 meter increments (66’, 82’, 100’, 116’, 132’, 150’, etc.)
Our gable style roof has a peak in the center and the structure’s support comes from its vertical walls rather than any interior support beams. This leaves the entire internal space open to suit your needs.
Once your needs go over 150 feet in width, you must use the beam and column construction. Technology for clear span structures has not yet reached the point of spanning wider than 150 feet.
