The client want to put solar panel at the workshop top, so we have to consider the solar weight loading when design the building, the structure is all made by high strength steel to ensure building safety after put on the solar panel, also sometime worker is going on it to check the solar panel running situation.
All support is made by pipe, the connection between the pipe is high strength bolt, it ensure the full support safety. Also the support part is made by special strength steel, which is safety enough for the entire building.
Purlin: galvanized squre steel, the steel get galvanized manufacture treatment will get a longer life time.
Roof sheet: use glass wool temperature insulation materials at the roof, which can against cold temperature out the building.
Solar panel: the panel is touched with roof panel sheet.
Rain gutter: gutter made by steel, in order to extend the gutter life time and prevent rust when it touched with rain water, we galvanized the steel gutter.
