The level will be used for storing garden tools, lawnmower,some paper records (1 medium archive box) garden hose & reel,various tools such as drill & drill bits, hand saws & various small tools.
I can't support the centre of the floor because I still want to park my car in the garage.
I currently have timber which is :- support posts every mtr (90 centimeters x 90 centimeters) Softwood rafters (145 mls x 45 mls) The floor will be yellow tounge flooring ( veneered chipboard 19 ml thick)
Should these be strong enough to support? the above mentioned items for storage?
