Archive rooms, stores cupboards and back-office storage all come down to the same problem: a large number of boxes, ring binders and files that need to be held securely, found quickly and stacked safely off the floor. The right shelving turns a jumble of boxes into an organised, retrievable archive. This guide explains how to choose archive and office shelving — sizing to standard boxes, working out load per shelf, and deciding between static and mobile systems.
What archive and office shelving has to do
Unlike pallet racking, archive shelving is hand-loaded — someone lifts and places each box or file by hand — so the priorities are different. It needs enough shelf depth and pitch to take your storage boxes, enough load capacity for the surprising weight of paper, and a layout that keeps everything reachable without a ladder for routine picks. Paper is heavy: a full standard archive box can weigh 15–20kg, and a bay packed floor to head height can hold a serious tonnage, so shelf and bay load ratings matter more than people expect.
Size the shelving to the box
Start from what you're storing. A standard UK archive/storage box is roughly 380 × 315 × 255mm, and lever-arch files stand about 320mm tall and 70–80mm wide. Two rules follow:
- Shelf depth — a 300mm deep shelf takes one row of standard boxes; 450–600mm depths let you double-bank boxes or store deeper transfer cases and box files.
- Shelf pitch (the gap between shelves) — set it just above your tallest item so you don't waste headroom. Around 300–360mm suits archive boxes; a shorter pitch suits lever-arch files stood upright. Adjustable shelves on 25mm-or-so increments let you tune each bay to its contents.
Then work out how many boxes per shelf and multiply through to check the shelf and bay stay within their rated load.
The right shelving for the job
For most archive and office stores, boltless steel shelving is the workhorse. Our SSI Schaefer R3000 heavy-duty shelving uses a boltless-lug system — solid steel shelves drop onto pre-punched uprights and lock in without nuts and bolts, so bays go up fast and shelf heights adjust in minutes as your filing changes. Galvanised or painted finishes, starter-and-extension bays and a range of shelf sizes make it easy to line a full archive room or fit a single stores cupboard. For small parts, stationery and loose items, GPC small-parts shelf units and tote racks add withdrawable trays and bins alongside the box shelving.
You may also see mobile (roller) archive systems, where bays run on floor tracks and slide together to remove wasted aisles — excellent for maximising a fixed-footprint records room, though they're a fitted, higher-cost installation. Our range is static commercial steel shelving; if you're weighing static against mobile, the deciding factors are how tight your floor space is and how often each bay is accessed. For a wider look at steel shelving formats, see our metal shelving units guide.
Five questions before you order
- What are you storing? Archive boxes, lever-arch files, or a mix — this sets shelf depth and pitch.
- How heavy will each shelf get? Full boxes of paper add up fast; check the shelf UDL and bay load, and don't load beyond it.
- How much floor space and height have you got? Tall bays use vertical space; a keep-safe reach limit avoids needing steps for daily picks (add safety steps for the top shelves).
- Static or mobile? Static boltless suits most stores; mobile roller systems suit a tight, high-density records room.
- Will it grow? Choose a system with extension bays so you can add to the run later without replacing what you have.
Loading and safety
Under PUWER, storage equipment should be suitable for its use, kept in good order and used safely. Load heavy boxes low and lighter items high, keep within the rated shelf and bay capacity, don't climb the shelving (use proper steps or a low platform), and make sure tall runs are floor-fixed or braced where the manufacturer requires it. Aisle widths should let two people pass and boxes be carried without twisting.
Frequently asked questions
How much weight can archive shelving hold? It varies by system and shelf size — always work to the quoted shelf UDL and bay load. Because paper is dense, it's easy to overload a shelf that looks half full, so check the figures rather than eyeballing it.
What depth of shelf do I need for archive boxes? A 300mm shelf takes a single row of standard boxes; go to 450–600mm to double-bank or to store deeper box files and transfer cases.
Is boltless shelving strong enough for a busy archive? Yes — boltless-lug systems like the R3000 use solid steel shelves and box-section uprights rated for heavy hand-loaded storage; strength comes from the components and staying within the rated loads, not from bolts.
Can I add to the shelving later? Yes — choose a system with starter and extension bays and you can extend the run by sharing uprights between bays, without dismantling what's already up.
