Where they are used and what they are made of
Shell roofs are the arched concrete roofs common on mills and sheds. They have a low load capacity, so a structure for them has to keep its added load low and follow the direction of the roof beams. FERO makes two shell roof structures: P3 for roofs whose beams run north to south, and P2 for beams that run east to west. Beam direction changes the load path and the fixing details, so the right one depends on the roof.
Both are made from SS400 iron, hot-dip galvanized to ASTM A123 with a 90 micron coating, and are supplied galvanized only. Structure fasteners are galvanized and module fasteners are SS304. Standard inclination is 10 to 45 degrees and standard design wind speed is 35 m/s (126 km/h), both customized per project. Final loading is checked against the roof's capacity during design, and a structural engineer should confirm that capacity before the design is fixed.

Common questions
Will a solar structure overload my shell roof?
The structures are designed for the low load capacity of shell roofs. Final loading is checked against your roof's capacity during engineering, and a structural engineer should confirm that capacity before the design is fixed.
Which structure do I need, P3 or P2?
P3 is for shell roofs with north to south beams and P2 is for east to west beams. Send roof drawings or photos and we confirm the beam direction.
Can shell roof structures be painted instead of galvanized?
No. Shell roof structures are hot-dip galvanized only, to ASTM A123 with a 90 micron coating.
What is the difference between a shell roof structure and an elevated shed?
A shell roof structure is made for the arched concrete shell roofs on mills and sheds, which have a low load capacity, and it follows the direction of the beams. An elevated shed is made for flat roofs, where it lifts the array above obstacles and cuts shading losses.
