Street lamp lighting calculation formula of { ( CAL + diameter) - 2 * wall thickness} * 3. 14 = plate specifications, work out the specification on the specification sheet is not exactly the same, then the specifications (to the nearest Plank to material) Example: the diameter of 60 mm diameter 140 mm wall thickness. 75 mm light pole with specifications 620
street lamp lighting calculation formula of
{ ( CAL + diameter) - 2 * wall thickness} * 3. 14' 3. 】 = plate specifications, work out the specification on the specification sheet is not exactly the same, then the specifications (to the nearest Plank to material)
example: the diameter of 60 mm diameter 140 mm wall thickness. 620 mm 75 mm light pole with specification of
all units are in counting is a standard unit of
standard unit of weight: kg ( Kg)
the length of the standard unit: m ( M. )
the density of the standard unit: (kg/m3 Kg/m3)
area: ㎡ ( Square meters)
sheet weight calculation:
= light pole weight specifications * 7 * * light pole height wall thickness. 82/2
plate cost calculation:
light pole sheet sheet weight * unit price = cost
galvanized cost:
* galvanized price = galvanized light pole weight cost
coating:
coating cost = coating unit price * coating area
light pole component ( The main stem flange + + lamp arm) Flange and the cost of the lamp arm calculation is consistent with the lamp post
light pole production cost = light pole plate cost + light pole galvanizing cost + light pole coating + rolled plate cost + wages + consumables
