SYSTEM 03.02 · VENLO CONFIGURATION
VN-1280: 12.8 m Venlo glasshouse steel frame.
Reference steel package for a 12.8 m Venlo: columns, trusses, gutters and bracing, with the glazing scope excluded in writing.
The 12.8 m span sets the truss depth and the column section. On this configuration the frame is fabricated, hot-dipped after welding, and inspected for column plumb and gutter level before packing — because those two tolerances are what the glazing crew will blame if the glass does not fit.
| Member | Section | Fabrication | Inspection |
|---|---|---|---|
| Column | SHS 100–150 or RHS | welded base plate | plumb ±5 mm |
| Truss | SHS / RHS chords + diagonals | welded | dimension check |
| Gutter | roll-formed or fabricated | butt-welded | level ±3 mm |
| Purlin / glazing rail | C profile or RHS | punched | line straightness |
| Bracing | Ø48.3 / SHS | bolted | visual + torque |

A mill quotation that says “Venlo greenhouse” without listing glass and glazing as excluded is ambiguous. Ours lists them.
