Building with envirotube is so easy.
In this photo we have a back door area being used as a dumping ground. Make great use of this space by shelving it out and making use of the height.
Full width = 1400mm
Full height = 1800mm
Left shelf width max = 540mm
Under window shelves max = 860mm
Depth maximum = 300mm
Calculating cut lengths
Shelf Beams (see diagram to the left for terminology i.e "shelf beams")
The left shelf maximum width to fit between the wall and the window (in the picture above) can not exceed 540mm. We must take in to account two connectors using 47mm each, so we need to deduct 94mm (2x47) from 540mm to give us a shelf beam width of 446mm. There are 12 shelf beams at 446mm required.
The long shelf beams on the right are calculated as follows using the dimensions above.
Full width = 1400mm - 540mm (left shelf beam including the connectors) = 860mm - 47mm (remaining connector at far right) = 813mm. We require 6 shelf beams at 813mm
Cross Beams (depth)
The maximum depth is 300mm. Once again we need to account for 2 connectors so we must deduct 94mm from 300mm to give us a cut length of 206mm. We will require 15 cross beams.
This will depend on the distance you want between shelves. In the diagram above, the bottom shelf needed a clear gap of 450mm. So we simply need to cut 6 upright beams at 450mm.
To calculate the length of the remaining upright beam under the window is as follows:
860mm (maximum height between floor and window) - 100mm (footing) = 760mm - 47mm (bottom connector) = 713mm - 450mm (upright beam as above) = 263mm - 47mm ( middle connector) = 216mm - 47mm (top connector) = 169mm (cut length of remaining upright beam under window) We will require 6 upright beams at 169mm.
Check upright beam measurements:
From the ground up
100mm + 47mm + 450mm + 47mm + 169mm + 47mm = 860mm
Use the same method to calculate the remaining upright beams required to complete the full height of 1800mm for the left section of the unit.
i.e, we have already cut the bottom section of the unit up to a height of 860mm (bottom of window height), that leaves 940mm. In the diagram above, we have finished the remaining height with three equal uprights (distance between shelves). The 940mm includes 3 connectors so we deduct 141mm (3x47) from 940mm = 799mm which is equally divided by 3 = 266mm. We require 12 upright beams at 266mm.
We recommend using a footing although it is not absolutely neccessary. Footings are useful when there is an uneven surface to take in to account. Footings can easily be cut to accommodate uneven surfaces and eliminate any rocking or leaning of the unit.
Also if there happens to be a spill or accidental flooding of the area, you only need to replace the footings should they become damaged.
Footings need to be longer than 50mm to allow for the connector to be fully inserted. We recommend 100mm.
