3x6 and 6x3 are one structure, pitched two ways
The footprint is 3 m by 6 m however it is written. What changes is which edge faces the public: pitched as a 6x3 it presents a 6 m frontage and 3 m of depth, and pitched as a 3x6 it presents 3 m of frontage and 6 m of depth. Which one you want depends on whether people gather along the structure or move through it.
Six feet, and a middle pair that lands mid-run
The 3x6 is the smallest footprint with legs between the corners: six feet, with the middle pair halfway along the 6 m side. Anything designed to run continuously along a 6 m side has to allow for that pair.
Two masts or three, depending on the frame
AF360, COL360 and XP360 carry three masts along the ridge. ZP360 spans the same 6 m on two. The ZP is therefore the only 3x6 with one fewer upright under the roof.
Ballast across six legs
Six feet share the load, so the per-leg figure is unchanged but the totals are not: 49 kg each at 30 mph makes 294 kg, 65 kg at 40 mph makes 390 kg, and 81 kg at 50 mph makes 486 kg. 486 kg is close to half a tonne, and a load to plan for in its own right. For the full 60 mph rating LP Tent specifies 130 kg per leg on hard standing, or stakes with 150 kg of pull-out on soft ground.
18 m² and what it serves
The space calculator gives 25 standing, 16 in seated rows or 10 at dining tables at normal circulation, before any support area is deducted. A small counter takes 6 m² of that and a bar or display 12 m².
35 kg to 67 kg, still a bag under 1.60 m
AF360 is 35 kg, COL360 44 kg, XP360 45 kg and ZP360 67 kg. They pack to between 1.52 m and 1.60 m, the same lengths as a 3x3 even though the covered area has doubled. What changes is weight: 14 kg to 29 kg more than the equivalent 3x3 frame.
Twenty-one metres of perimeter, in bays
Two 3 m ends and two 6 m sides, and the six feet divide each long side into two 3 m bays. Walls are specified bay by bay, so a 6 m frontage can be open, half-walled or fully closed in 3 m increments. Six metres of printed valance is where the XP and ZP tension bar earns its place.
