What's the Difference between a Clearspan and a "Traditional" style Marquee ?

Clear Span - Our Modular Aluminium Marquees 
This type of structure has been developed over the last fifty years, with the incorporated track in each span allowing the user to assemble in sections, set up and anchor the frame of the structure, then cover it in manageable portions by inserting the sealing edge of the roof cover into the frame and pulling it over with ropes. The modules are interchangeable so the length of structure can be adjusted to suit each site, if there are unused modules they can be used on another structure. 
 
Benefits: Easy to assemble with minimum technical knowledge, modular system gives lots of flexibility, interior not interrupted by posts, no guy rope trip hazards outside for maximum use of available space (for instance in a given 42’ width you could only fit a 30’ traditional, or a 40’ wide clear span) less stakes to put in, can still be erected in windy conditions.
 
Traditional Marquees 
This is the marquee that started everything. Held upright by tensioned ropes to stakes usually 5 to 6’ away from the marquee, made with centre masts (King Post) supporting a canvas or similar cover, an outer ring of wall posts held upright by more guy lines support the roof and side wall. 
 
On larger versions you will find a second inner ring of intermediate posts (Queen posts) Some versions are made in PVC, other in 15 or 20’ lace-up sections dictated by the roof sheet.
 
Drawbacks: The guy lines mean it has to be 10 to 12’ smaller than the available space in both dimensions, lots of stakes to put in - usually every 6’. The interior layouts have to work around the support posts, with the risk that someone will trip over guy or stake. Some knowledge of ropes and knots is advisable. 
 
Benefits: Generally low tech repairable material such as canvas or other similar breathable fabrics. Good humidity. More forgiving when erected on uneven sites. 
Tube Frame Marquees
A Simple tube frame available in many versions (and weights), consisting of steel and aluminium tube. They are usually covered by PVC material which is tied on to frame. 
 
Drawbacks: Generally not very adaptable, often not modular in design meaning several different sized units required. This also means means that occasionally large expanses of cover are needing to be fitted and tied on. 
 
This is especially difficult when windy. 
 
Some of these are only anchored after being covered and the frames can get heavy at 30’ wide. 
 
Benefits: Mostly no centre posts and Cheap.
