PM Industries manufactures, supplies, and stocks MS Flat Bar in a range of widths, thicknesses, and lengths. The rectangular cross-section is what makes flat bar useful where other sections aren't. It sits flat, aligns cleanly, mounts flush against other surfaces, and distributes load evenly across its width. For brackets, base plates, frame members, and structural supports, those handling and assembly characteristics matter as much as the mechanical properties of the steel itself.

Mild steel's low carbon content keeps fabrication straightforward. MS flat bar cuts cleanly with standard saw, plasma, or flame cutting equipment. It bends without cracking on standard press brakes. It welds with common MIG and arc processes without preheating in most standard thicknesses. For fabrication environments that process large volumes of steel section, that processing simplicity translates directly into faster throughput and lower labor cost per piece.

Structural versatility covers a wide range. Thin flat bar works for brackets, reinforcing strips, gussets, and sheet metal backing. Thicker sections handle base plates, machine mounting pads, structural frame members, and load-bearing supports. The same material in different cross-section dimensions serves both purposes, which simplifies procurement and stock management for fabrication workshops handling varied project types.

Corrosion protection applies through standard surface treatments. MS flat bar will rust in outdoor, wet, or corrosive environments without a protective coating. Paint, powder coat, hot-dip galvanizing, and epoxy coatings all adhere well to properly prepared mild steel surfaces. For outdoor structural applications, galvanizing is the standard treatment that provides practical long-term protection at reasonable cost. For indoor or dry environments, painted or untreated mild steel performs adequately for many applications.

Bar is available in a range of widths, thicknesses, and lengths with standard mill certification. Custom cutting to length and width is available. Contact PM Industries for stock availability, dimensions, and pricing.
