Square tubing or angle iron? It is one of the most common questions at the counter at Metal Supermarkets Atlanta in Marietta. Both shapes come in mild steel and aluminum, and both weld well, but they handle load very differently.
Square tubing is closed on all four sides, so it resists twisting far better, making it the go-to for carts, gates, trailer tongues, and table legs. Angle iron is lighter per foot and easy to bolt through, which suits shelving frames, brackets, and bracing. Many builds use both. Tube also gives a clean, finished look with no open edges, while angle offers a flat face for mounting panels and decking.
Our Marietta team cuts both shapes to length, miters corners, and drills holes with no minimum order, in mild steel and aluminum, for fabricators, welders, and DIY builders across Cobb County, Smyrna, Acworth, and Northwest Atlanta. Trailer frames, welding carts, shelving, and gates are among the most common projects.
