Flat Bars are rectangular steel bars with a flat, smooth surface, commonly used in construction, fabrication, and manufacturing. Their simple, versatile design makes them ideal for structural supports, bracing, and general-purpose steelwork. Flat bars are easy to cut, drill, bend, and weld, making them a staple in both heavy-duty and light industrial applications.
They are a cost-effective, versatile steel solution for construction and fabrication projects. Their flat profile allows for easy integration into structural designs, machinery, and architectural elements, making them essential in both industrial and decorative applications.

Common Questions
Flat bars in the Philippines are available in a range of standard sizes, typically defined by thickness × width. Common sizes include:
• Thickness: 3mm, 5mm, 6mm, 10mm, 12mm
• Width: 19mm, 25mm, 32mm, 38mm, 50mm, 65mm, 75mm, 100mm
They are usually supplied in standard lengths of 6 meters, though custom cutting may also be available depending on the supplier. For instance, Regan Industrial, the leading steel supplier in the Philippines, offers custom services to meet specific size and project requirements.
Flat bars and steel plates differ mainly in size, form, and application.
• Flat bars are narrow, long rectangular pieces with precise dimensions, commonly used for fabrication and general construction.
• Steel plates are wider and thicker sheets designed for heavy-duty applications such as bridges, shipbuilding, and industrial structures, where greater strength and load capacity are required.
Flat bars are versatile steel products used in structural framing and bracing, gates, fences, railings, machinery fabrication, support brackets, roof trusses, and various industrial and architectural projects.
