Hello,

I need to build homemade small crane, with steel squares. Before buying material, would like first to design product, and simulate static load.

For example, one nearest company is offering below steel. I have been searching by Google, and just not able to found technical specification, so I could create custom material.

If anyone know a good place on internet, I would be very pleased for sharing that information.
