A commercial kitchen bench is not a category, it is a set of eight attributes that together define one article: length, depth, height, top construction, frame, undershelf, edge and upstand. Two benches can look identical in a photograph and differ in four of those eight, which is why a photograph is not a specification and why the quotation has to list them.

The right-hand column is what we will build if you do not say otherwise. Change it deliberately or accept it knowingly.
| Attribute | Range | Default here |
|---|---|---|
| Length | 600–2400 mm, any length above 1800 | Made to length |
| Depth | 500 / 600 / 650 / 700 mm | 600 mm |
| Height | 850 or 900 mm, ±2 mm | 900 mm |
| Top | 1.2 mm skin over frame, or 5–6 mm plate | 1.2 mm skin |
| Frame | 25, 38 mm tube, 1.2 or 1.5 mm wall | 38 × 38 × 1.2 mm |
| Undershelf | none, flat, or turned-up 20 mm | Turned-up, welded |
| Edge | square, folded, or machined | Square, machined |
| Upstand | none, 100 or 150 mm | 100 mm, welded |
Note that height and depth are the two where a default will actually be wrong. A bench for a wheelchair user, a bench against a low window and a bench that takes a specific machine all override the default, and all three are cheap to specify now and expensive to change later.
Everything else is secondary to this one. A 1.2 mm skin welded to a frame and a 5 mm plate top are different products with different failure modes.
The mistake runs both ways. A buyer who has been sold plate for a plating-up bench has paid for weight that does nothing; a buyer who has been sold a skin for a butchery bench has a top that will be dented within a month and cannot be dressed flat again.
Four details account for almost every bench we are asked to repair.
Not the material. These five, in order of how often we see them.
The clearance point is worth a sentence on its own: a bench sealed to the wall cannot be cleaned behind, and a bench on 100 mm legs with a sealed plinth can. Most inspectors will accept the plinth; almost none will accept a bench that cannot be moved for a deep clean.
Eight lines, and the quotation comes back in 24 hours with the top, the frame and the packing costed separately.
We build in 1.2 or 1.5 mm skin, or 5–6 mm plate, in grade 304 as standard and 316L where the bench is wet or chlorinated. Lead time is 15 working days from a confirmed order, shipped assembled with the upstand protected, and each bench carries an inspection sheet recording height, squareness and the joint schedule. What we cannot do is build to a photograph — the eight attributes have to be written down, and writing them down is ten minutes.
