Neat product that seems worth looking more into. Framing system for solar panels to make a shed or what not. Iron Matrix https://www.ironmatrix.com/ Video about the product
Seems interesting enough but the details are scant to say the least. No pricing is indicated at all. NO structural information for foundation, insulation or finishing details.
The other videos show a screw pile setup for foundations on larger products. I wouldnt use it for a house, but for a shed or green house sure. Or better yet all in one well pump room.
