Solar structures that survive the typhoon
Solar carports, rooftop solar frames, inverter and switchgear buildings and battery shelters for malls, factories and campuses – designed for the full NSCP wind load and galvanized for 25 years.
- 25 yrs
- Design life with galvanizing
- NSCP
- Full wind load on panels
- Roof checks
- Before solar is added
A solar array is a sail
Panels catch the wind from above and below. In a typhoon the uplift on a carport canopy can be several times the weight of the steel, so columns, rafters, purlins and base connections are designed for it – not taken from a catalogue built for a calmer climate.
For rooftop solar we check the existing purlins and frames first and, where needed, supply strengthening steel together with the panel support frames.

Frequently asked questions
Can my existing roof carry solar panels?
We check the purlins, frames and connections for the extra load and wind effects, and supply strengthening if needed.
Do you install the panels?
No – the solar EPC installs panels; we design and supply the steel to their layout.
Ready to price your building?
Send the layout, the site location and your target date. We reply with a frame concept, steel tonnage and a CIF or DDP price.
