So this is sort of 'thinking outside the box', about how to buy 500 heavy duty cardbaord boxes, in Sacramento USA, asap.
Background: Late 2021 I ebay-bought several thousand service manuals, stacked in a storage unit near Sacramento USA. Info:
http://everist.org/dm/ (needs updating)
The unit, which is 10' by 15' is all full like that.
The volume of the raw pile is about 2/3 the volume of a 20' shipping container. And I'm trying to get them to Sydney Australia. This is hard.
Status: I have a shipping quote, currently valid till 22nd Jan. That's for providing a container onsite to be loaded, then transporting it to Sydney.
_Loading_ it, that's my problem. Should be possible right, just find some boxes and a crew to pack the manuals in them, and stack in the container. Ha ha ha...
Funny thing is, I thought buying suitable boxes would be relatively easy. For instance here's a company with a huge range of boxes:
https://www.uline.com/BL_418/275-Lb-Test-Double-Wall-BoxesWhat does 'suitable' mean?
This is a typical manual.
Because of the volume, I need boxes that will pack the manuals efficiently (or they won't fit), AND strong enough to allow box stacking to the container ceiling. Five layers deep. Books are heavy!
The container will go by truck and sea, and the boxes have to stand up to shipping motion.
Plus I will keep the boxes for storage. So the cardboard should be the strong '3 layer' type, 1/4" thick.
Most of the manuals have a height of 11.8". And they must be stacked mostly flat in the boxes.
So one of the box base internal dimensions should be 12". Critical to achieving space efficiency.
The other base dimension can be 15" to 22" internal. Allows for outlier large manuals, and some placed upright to fill spare space.
18" is optimal; it allows two stacks of a common smaller size manual. Also results in a good fit to the shipping container width. (2414mm. Fits 5 boxes, final gap = 64mm)
22" allows two stacks of typical large manuals. But also fits the container poorly (4 boxes, 128 mm gap) and is getting into 'heavy to lift' range.
The box height should be in the range 18" to 20". The ideal is to get as many manuals in a box as possible without ending up with a box too heavy to lift, or crushing items at the bottom, while still fitting well in the internal height of a shipping container. (2698mm)
There's often going to be a bit of empty space at the top inside each box (due to thick manuals), and bigger boxes minimize that percentage loss of total space. Often can pad with thinner manuals, but they won't always be to hand.
Plus for heavy duty boxes the top and bottom flaps thickness is significant; 1/4" x 4, an inch.
An internal box height of 20", with 1/4" walls, gives an external taped height of 21" (533.4mm.)
shipping container internal H = 2698mm. Stacking boxes 5 deep leaves just 1.25" gap at the ceiling. Close!
This gives desired box internal dimensions (same order as the ULine online table):
Length Width Height
15" to 22" 12" 18" to 20"
Pref 18" Pref 19.5". NO GREATER than 20".
And this, btw, is much like a typical 'house moving box'.
The base is a rectangle approx 1 to 1.5+ ratio, and the height is at least 18".
Roughly how many boxes?
A 20' container internal length is 5898mm. A 12" box internal width plus walls = 318mm.
Fitting 18 rows of boxes. Times 5 per row = 90 boxes per layer. Times 5 layers = 450 boxes.
Say 500 boxes, to allow spares, some used flat as gap fillers, and maybe some for manuals that don't fit in the container and have to be shipped separately.
But sadly and mysteriously ULine have *nothing* like that. Anything in their stock list with something like the desired base dimensions will also have too small a height.
So I'm asking the Net. Does anyone know of a supplier of boxes on the US west coast, with a stock of suitable solid cardboard boxes close to that size? Who could deliver to Roseville CA this week or early next?
Apologies if I don't reply for a while. Bit busy atm.
So far others have suggested:
Home Depot, Lowes, and U-Haul.
Grainger (Grainger Industrial) may have more selection than Uline... whether they have stock might be another issue.
McMaster-Carr or Global Industrial.
