CASE 05 · PC MULTI-SPAN
PC multi-span with automation: where the frame has to accept someone else's kit.
An intelligent PC multi-span house where climate computers, sensors and vents were supplied by others. The frame's job was to provide mounting points that the automation contractor could trust.
What was supplied
PC-supporting purlins at the sheet maker's span, gutters, and defined mounting points for sensors and vent drives. The mounting points were agreed with the automation contractor before punching, because a sensor bracket added later means drilling through a coated member on site.
What the project taught us
“Intelligent” greenhouses fail at the brackets. A vent drive fixed to a purlin that was not designed for the reaction will distort the purlin and then jam. We now ask every buyer one question: which third-party equipment will hang from the frame, and at what load?
Relevance to an export buyer
If you are buying automation separately, send the mounting loads with the frame enquiry. It is a two-line email that saves a site problem.
