Buying Guide

Choose the right steel grade

Select A36 for structural welding and general fabrication, or plain hot-rolled steel for simpler bending and cutting tasks

Match thickness to project load

Thicker plates (1/4" and above) handle structural and load-bearing tasks; thinner sheets suit brackets, templates, and light-duty parts

Consider size and quantity

Buy the plate dimensions and pack counts that reduce waste—single large plates for full projects, multi-packs for small parts and jigs

Look for prep features

Pre-drilled holes and consistent machining reduce prep time for bolting and fixturing, especially in base plates and mounting parts

Check finish and workability

Hot-rolled surfaces are scale-prone but easy to weld and machine; round or square blanks can simplify cutting or turning operations
