Home > Flat Bars
Flat Bars are solid rectangular metal bars used extensively in structural fabrication, machining, automotive, shipbuilding, aerospace, and general engineering applications. Their wide surface area, uniform thickness, and stability make them ideal for brackets, frames, base plates, support structures, machined parts, and precision tooling.
Flat Bars are produced in stainless steel, carbon steel, alloy steel, tool steel, duplex, nickel alloys, copper alloys, and titanium — each offering specific strength, corrosion resistance, and machinability advantages.
Compared to square, round, and hex bars, flat bars offer:
Flat Bars are essential in industries requiring precision, rigidity, corrosion resistance, and structural integrity.
Flat Bars are produced using multiple metallurgical processes:
Manufactured by rolling billets at high temperature.
Features:
Cold drawing improves tolerance and straightness.
