Two codes cover most enquiries: WS-2436 and WS-3030. A third line, WS-KD, is the bolted knock-down reading of the narrow module when the buyer needs 40HQ density instead of a closed box.
| Item | WS-2436 volumetric | WS-3030 volumetric | WS-KD bolted pack |
|---|---|---|---|
| External size | 6058 × 2438 × 2896 mm | 9000 × 3000 × 2896 mm linked pair logic, shipped as coordinated boxes | Same 6058 × 2438 plan, frame split |
| Chassis | Cold-formed steel (CFS), welded lugs | CFS with a site link at the marriage line | Bolted knock-down, torque record required |
| Coating | Z275 where the sheet says galvanized | Z275 on listed members | Z275 plus cut-edge repair note |
| Wall | 50, 75 or 100 mm sandwich panel | 75 or 100 mm | Same cores, joints closed on site |
| Sample U-value | 0.45–0.60 W/m²K at 50–75 mm foam, skirt excluded | 0.35 W/m²K target with 75 mm PIR on the 2021 school reading | Depends on the core chosen, not on the bolt pattern |
| Lifting | Four corner lifting points | Lug set per box, link after set-down | No single-box lift of a finished room |
| 40-foot freight | 1 module per flat rack | Width may bar a standard flat; confirm the route | Wall sets can reach 4–8 equivalent rooms per 40HQ when floors travel separate |
| Fit-out on the sheet | Power, data, HVAC interface, optional sanitary | Same list, marriage-line seals added | Linings often site-fixed |
A 10 by 10 foot room is smaller than WS-2436 and is treated as a partition layout inside a module, not as a separate chassis code. A 16 by 40 foot portable building is read as a linked run, not as one CSC container. Prices are quoted per issued revision. This page does not print a currency figure because fit-out and freight move the number.
Repeatability limit: jigs control the run after the initial unit passes. They do not correct a site foundation that is out of level. Corrosion limit: Z275 does not protect a ground cut that was never painted. Transport limit: WS-3030 width can fail a road permit that WS-2436 would pass, so the wider code is not a silent upgrade.
Ask for WS-2436, WS-3030 or WS-KD and the revision date you need. The reply is the data sheet or a note that the code does not fit the route.
