I m trying to lift a 4 ton shed with a crane and need a 90* angled steel to support the strap, because there is no support running the long way at the very bottom (only the short way). Will the 1/4" 90* angled steel be sufficient for this lift?
Answer:
Unfortunately, you have not provided enough information to answer your question. In general, there are several analyses that you must do:
1. Assuming that the 90* angle bracket is bolted to something, you must do a bearing analysis of the hole, and a tensile analysis of the area around the hole with the Kt of the hole included.
2. You need to do a tensile strain calculation at the corner of the bracket to make sure that you don't near the elastic limit of the material.
3. You need to ensure that your load path provides a minimum of eccentricity near the attachment point so that you don't have out of plane bending of the bracket.
The following additional information needs to be provided as well:
Alloy and heat treat of the bracket (for strength and stiffness).
Dimensions of the bracket (including holes)
How many brackets total are supporting the load?

GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
