I would like some expertise on this.
We have this pantry in our kitchen which SWMBO wants
reorganized/re-shelved to make it more useful - right now
(and for the last 18 years), it has had fixed particleboard shelving
of various depths.
The pantry space is 24 (deep) x 30 (wide) x 96 (high)
and a 24 inch door for access.
I am thinking of buying (1) - 16x96 drilled melamine sheet and (1)
12 x 96 drilled melamine sheet - each of which I would crosscut
to give (2) 48 inch sheets of each width. The 16 would rest on the floor
on either side of the pantry while the 12 would rest on the 16's - all
screwed to studs. Then I would use standard 3/4 melamine
for the adjustable shelves - some 16's & some 12's.
I would support the adjustable melamine shelving with metal shelf
pins (1/4 inch) - and no back support (gulp!?)
Would such a shelf support a double high, triple deep of my Campbells
Chicken Noodle (i.e. say, 50-75 pounds each if needed?)
I DAGS (see link at end) and came up with this interesting chart.
If I understand this correctly, a 30 inch span of 12 inch melamine
will support 350 pounds before deflecting 1/4 inch. They don't
mention 16 inch x 30, but from the chart, it looks like it would hold
even more weight before deflection.
Any thoughts - besides the fact that I am over-thinking this?
Thanks!
Lou
Here's the chart:
--------------------
Shelf Deflection of 1/4" by Estimated
Total Distributed Load in Pounds
This table shows loads that cause various 3/4"
unfixed 8"- and 12"-wide boards to sag 1/4" when
spanning 30", 36" and 42". Loads required to
cause sagging less than 1/4" may be estimated
by direct proportion. For example, the load
required to cause a 1/8" sag is one-half
that of the values in the table.
