The wall is measured before cutting
Real dimensions are taken and the shop drawing re-issued against them.
If skippedA wall 20 mm out of plumb turns a designed 5 mm gap into a 25 mm trench nobody planned.
The largest share of what we make, and the element where the surface behind the metal — not the metal — determines whether it looks right.
Grades quoted are 304 and 316L; other grades are sourced to order and named in the quote. Cut and finished in our own factory in Foshan.
Wall and column cladding is the largest share of what we make, and the element where the wall behind the metal decides the result.
Two shapes: flat cladding on a wall, and casings around columns. Flat cladding is a flatness problem. Column casings are a measurement problem, because no two columns are the same size.
Two or four segments, formed, seam set at a recessed reveal, fixed without visible screws. If the building has fourteen columns, we draw fourteen casings, because the tolerance on a structural column is not the tolerance on a cladding seam.
Panels on a concealed frame with a constant shadow gap. The frame is part of the design, not a detail for the installer to resolve.
| Property | Figure | Note |
|---|---|---|
| Thickness | 1.0–3.0 mm | 3.0 mm is for impact zones and sharp V-groove corners |
| Panel size | 1500 × 4000 mm | The maximum single-piece face we can give you |
| Seam gap | 3 mm ±0.5 mm | Constant — this is the number people notice |
| Flatness | 1.2 mm / m | Straight edge, both diagonals, every panel |
| Radius | ±3 mm over an 8 m run | Curved work is assembled as a run, not as segments |
| Fixing | Concealed | Visible fasteners only where the detail asks for them |
| Site cutting | None | Parts arrive at the size they will be fitted |

Four measurements per column, one drawing per column.
If skippedOne common casing, packed out differently on site, with a different shadow line at every column.
Curved work is joined and measured as one run on the floor.
If skippedSegments within tolerance still make a run that is out at the end, because errors accumulate.



Grade and finish are a specification. Whether two panels meet cleanly, in one colour, with no cutting on site, is the job.
