Heavy duty gaylords for parts and metal
Parts makers and metal shops use full-bottom 4 and 5 wall gaylords, often short ones, because the weight sits on the base and a tall box can exceed what a floor takes.
Weight changes everything
A pallet of machined parts, castings or scrap can weigh two thousand pounds or more in a box that fits on a forklift. The base takes the load. The walls only hold the shape. That is why heavy duty gaylords for parts are full-bottom and 4 or 5 wall, often shorter than the standard 36 inches.
Heavy duty gaylord boxes are cited at 1,500 to 2,200 lb for four walls and 2,000 to 3,000 lb for five. Those are seller ranges, not guarantees. The maker's rating for the exact box is what counts, and a used box that is not Grade A has lost some of it.
Choosing walls, bottom and height
| Load | Walls | Bottom | Height |
|---|---|---|---|
| Small castings and fasteners | 4 or 5 | Full flap | 24 in |
| Bar and rod offcuts | 5 | Full flap | 28 to 30 in |
| Sharp scrap | 5, with a heavy liner | Full flap | 24 to 30 in |
| Packaged parts | Triple | Full flap | 36 in |
| Light assemblies | Double or triple | Partial on a pallet | 36 in |
Weigh a full box on your floor scale before you order. Gross weight less tare is your load, and the load tells you which row to read.
Where this plays out here
Parts makers in Montgomery County, along the Schuylkill from Norristown to Conshohocken, and in Delaware County near Chester ask for these boxes. The steel towns of Coatesville and the machine shops around them do too. The Philadelphia Navy Yard, with 150-plus companies on a 1,200-acre campus, includes shipbuilding and light manufacturing that use bulk boxes of many kinds.
Overseas shipments of automotive parts often go in expendable packaging because returning it costs too much, and Packaging Corporation of America offers expendable triple-wall corrugated for just that. If your parts ship one way, a used box may fit your trip count better than a returnable one.
Common mistakes
- Ordering a tall box for a dense load and finding the floor cannot take it.
- Choosing a partial bottom for loose parts that sit directly on the base.
- Ignoring pallet overhang, which weakens the box.
- Letting boxes sit in a damp yard, where board loses about half its strength as humidity climbs.
