I've just downsized from a 2,000 Sq Ft Unit to a 150 Sq Ft unit. I've yet to get it how I want but the design I have come up with is amazing.
The racking is all diy, made out of wood and metal. Each product has its own shelf and they are stacked all the way to the ceiling which is 3 metres high. The shelving is adjustable both in height and in width.
The width has to be the same for the entire column from the floor to ceiling, but the next column can be a different width. The column widths can be adjusted at any time but it has to be the whole column.
The row heights can be different for each shelf and the adjustment for each shelf will take less than 10 seconds per shelf. The adjustment for each shelf is in 1cm increments, so it will look almost like the boxes are stacked on top of each other but they are not, this means that the wasted space is kept to an absolute minimum.
I've worked out that on 1 column that is 3 metres high I can store on average 30 boxes, this means the wastage for the 1cm gaps equate to the equivalent of 3 boxes per column. Bearing in mind though that stacked on top of each other I could only fit 33 boxes from floor to ceiling anyway and obviously that would be impractical to work like that.
The design means that I can take a box out of anywhere in the column and the column will still look all neat and tidy, it will just have an empty space where the box was. It also maximises the amount of boxes I can store and still have the unit operational.
It's taken me several weeks to think it through and come up with the perfect design that is the most efficient to use and build it in the quickest and cheapest way. Once it's finished I estimate I should be able to pick and pack at a rate of 40 to 60 parcels per hour. In the 2,000 Sq Ft unit it was around 25 to 30 per hour.
Everybody recommends these racking systems, they are quick to put up but the amount of space you waste is huge, It is also a messy way to operate. My system is designed to solve those two problems.
