4" x 4" Heavy Duty Square Flat Steel Metal Base Plate With Holes
This 4" x 4" heavy-duty square steel base plate provides a solid, reliable foundation for mounting posts, columns, and equipment. Pre-drilled with anchor holes for secure installation, it is an essential component for construction, fencing, and industrial fabrication projects requiring stable structural support.
- Industrial-Grade Structural Steel
- 4" x 4" Square Profile
- Pre-Drilled Anchor Holes
- Structural Support & Mounting
Our 4" x 4" base plates are manufactured from high-quality, low-carbon structural steel, known for its excellent weldability, strength, and durability. This material provides the necessary rigidity to distribute loads effectively from a post or column to a concrete foundation. The flat, square profile ensures a stable mounting surface, while the pre-drilled holes are positioned for standard anchoring hardware, simplifying the installation process. This makes it an ideal choice for both new construction and MRO (Maintenance, Repair, and Operations) projects requiring a dependable hardware solution.
Engineered for versatility, this heavy-duty base plate is a critical component in a wide range of applications. It is commonly used in commercial and residential construction for securing fence posts, railing supports, and structural columns. In industrial settings, it serves as a secure mounting flange for machinery, equipment, and support frames. Fabricators in the Los Angeles area rely on these industrial-grade base plates for creating custom structures, from ornamental ironwork to heavy-duty industrial assemblies. Its robust design ensures long-lasting performance in demanding environments.
