Metal A Frame Roof Truss Design

[JERRYE]

Hello Everyone
After 45 years in the electrical industrial construction industry I have retired and am in the process of building a house in Queretaro Mexico. I was hoping to find a structural engineer to assist me in designing A frame roof trusses to support a simple metal roof
As it is a remote area availability of truss material is limited to 1” to 4” square metal tubing 14 & 12 gauge
Anyone who could spare the time to assist me would be greatly appreciated

Forums are not really set up to do engineering work for people, try looking for (more) local engineers qualified and/or licensed for your work.
I believe there is an AISC specification for cold-formed steel structural members, your pieces may or may not fall under that.
