Collection: Corner Posts

At Kampco Steel Products, our Corner Posts collection features a variety of steel and aluminum posts—including radius profiles, square posts, return legs, and drip rail options—designed to reinforce corners and vertical edges for trailer builds or repairs.

Why Choose Our Corner Posts

  • Built for Strength & Longevity: Our corner posts are engineered to withstand everyday road vibration, cargo movement, and the elements—helping ensure your trailer’s corners remain square and protected.

  • Tailored to Your Trailer Type: Whether you’re building an enclosed cargo trailer, a utility hauler, or a custom recreational trailer, you’ll find post profiles that match your build: 1 ¾″ radius, 5″ radius, square-leg designs, “leg out” options, and return-leg styles.

  • Precision Fit & Easy Installation: With standardized radii and leg configurations, it’s simpler to measure, order, and install the correct corner post—reducing fabrication time and making your trailer build more seamless.

  • Enhanced Finish & Protection: A proper corner post not only provides critical support—it gives your trailer a clean, finished look while helping guard vulnerable edges from damage, corrosion, and wear.

Ideal For: Cargo Trailers, Utility Haulers & Custom Builds
