First,let me ask you:have you researched the building permits,insurance(liability,business,etc.)coverages,licensing and mercantile certificates that will be required to operate a store and 'factory' from those two existing structures? Before I was retired due to disability,I was a federally certified electrical+structural engineer. Now I have a flock that keeps me busy and happy!
Second,once all that research is done...that lean-to should be treated as a separate building. Judging just from the pictures,since I have no other data to extrapolate from,the supports for that front header are insufficient to carry dead load-let alone live loads from precipitation and stress-factor loads from wind shear. It appears to be only a single 4x4 post at each corner,that doesn't have a king nor jack stud nailed to it to tie into sill and top plates as per IBC. Furthermore,those stud walls "should" be 2x6 stud walls to carry the additional compressive dead loads of the integral shelving showing in the pictures.
Third,according to the BOC,Oriented Strand Board(OSB),can be used in exterior applications;as long as the OSB is not exposed to the elements. OSB is to be used in exterior sub-walls,sub-floors and sub-roofing where its application is not normally exposed to moisture and/or wet conditions. That header needs to be covered with tar paper,at the very least!
You could build a deck floor,but make it stiff. USE all pressure-treated lumber. Rim joists should be 2x10's and floor joists 2x6's;floor joists set flush to BOTTOM of rim joists. Double layer of 3/4 pressure treated,tongue and groove plywood sub-floor. This leaves an inch between the top of the sub-floor and the top of the rim joist. I recommend that you locate your stove in the far left rear corner(as you're standing where photo was taken),away from your front exit,in case of a fire and therefore not blocking an emergency exit. You will need to fireproof both the floor and the corner wall(s) a minimum distance(I don't have that specific code book handy at the moment.) For the floor under the stove,you could use concrete backer board,thin-set adhesive,with latex admixture,unglazed quarry tile and grout. The corner wall(s) would require a slightly modified installation,by adhering,24 gauge minimum,aluminum sheet,then the rest of the application continues,as in the previous floor application. You may be required to put an exit door on the rear(adjacent) wall. The remaining floor is left up to you,whatever you do make it easy to keep clean.
Yes,all that junk inside there,has got to go. If it's not essential to the manufacture of your products,stow it somewhere else! I get somewhat unnerved when gasoline,propane and sodium Hydroxide get in close proximity of each other;especially in confined,unventilated spaces. Also,updating the lighting,may improve safety AND productivity. Additionally,having impervious,lightly colored,wipe-down walls instead of exposed OSB,will aid in ease of cleaning your facility after buildup of volatile oil residue and lye vapors. You do all these things to lessen the cost of your product and liability insurance. Also,you lessen the risk of fire.
Make sure,after all of this,you keep all receipts and make a record of all costs. You'll need this to save your business your property and most importantly your arse when the IRS comes a knocking! Dayum! Almost wrote a book!
All y'all take care!
