Deal-ender damage
Deal-ender damage — Impact damage to an upright's loaded zone — a bent or creased column section between beam levels. Uprights are the only compression members in the bay; a bent one is not cosmetic and not field-straightenable. One creased column ends a used-deal or cuts that bay out of it.
Paperwork problem
Paperwork problem — Missing load placards, unknown origin, no capacity plate: in most markets a used installation without load ratings cannot be legally loaded to any claimed figure — until engineered plates are produced or re-certified for the frame. Not damage; a price and a lead-time item.
| Upright columns, both faces | any crease or bend in the loaded zone — walk past the whole set if found |
|---|---|
| Beam ends and connectors | deformed hooks or safety-tab slots mean a overload history; tabs missing is cheap but telling |
| Column hole wear | egged-out beam slots say the rack lived with misjudged beam heights |
| Base plates and anchors | bent plates and sheared anchor holes say forklift history and new floor work |
| Cross-bracing | bent braces are replaceable — but note how low the hits happened |
| Scale of it | 5 % damaged is used-stock normal; 30 % damaged is the previous tenant's farewell |
The walk takes twenty minutes and saves the whole deal
Used racking is sold by the photo set and won or lost by the walk. Photographs flatter the way car ads do: they show the clean faces at good angles. What matters is what a walk finds that photos systematically hide — the creased column behind the stacked shrink film, the beam hooks with the safety slots torn out, the base plate bent toward last year’s forklift. The walk order above exists because deal-enders live in uprights, and the deal is only worth walking further if the columns pass.
Budgeting used racking honestly
A fair used price assumes a percentage of bays will not re-erect — brace replacements, a scatter of new beams, new anchors and bolts are not surprises but the bill of materials for the move. The arithmetic that makes used racking worth it is capacity-per-dollar against new, with your engineer’s re-certification cost included; when that math closes, it closes big. The arithmetic that kills it is buying damaged-stock cheap, then paying new-stock prices for the replacement parts from the current brand owner — the used deal turns into a parts purchase with delivery.
Mixing used frames without a brand mismatch
Used racking of mixed origin meets in one building more often than it should. The connector geometry between beam and column is not a standard — a beam that seems to sit fine on another brand’s column may not be carrying the way the capacity plate claims. The safe used-deal pattern is to buy bays, not parts: complete frames with matching uprights and beams, kept as sets, and to treat mixed-brand offers as engineering projects, not bargains.
Can a slightly bent upright be hammered straight?
No, and every honest racking person says no for the same structural reason: the column is a thin-walled compression member whose capacity comes from its shape, and straightening by hand changes the shape while destroying the steel's memory of it. Replaced, never repaired — which is also the correct answer to used-deal sellers who offer to 'make it right'.
What paperwork should a used-racking deal include?
Original or re-engineered load capacity plates per frame — the figures the bay may legally carry; the beam and upright models with their connector type, because used mixing across brands is a compatibility lottery; and the anchor and floor plan if the frames go into a new building. A seller who cannot produce the capacity figures is selling steel, not storage — price it that way.
