Black Aluminum Inground Post, replacing traditional wooden posts, redefines the durability of fences. Our 3″ x 3″ x 10′ ground mental fence posts are made of aircraft-grade aluminum. It can effectively prevent warping, corrosion, and rot, maintaining structural integrity for decades. Its lightweight and high-strength design supports seamless integration. With FENCE DEPOT’s vertical, horizontal, or traditional fence kits to form a sturdy frame. It can withstand extreme weather, ground displacement, and heavy loads without tilting or shrinking.

For design versatility, this black metal inground post is available in standard black or custom RAL colors. Its 6-foot (about 1.8 meters) ground clearance and 4-foot (about 1.2 meters) buried depth optimize stability. The integrated cap prevents water from accumulating at the top of the post. As a 100% recyclable solution, this aluminum post combines environmental performance without compromising strength, suitable for residential properties, commercial locations, and decorative garden boundary solutions.

Black Steel Inground Post

Measuring 3″ x 3″ with a total length of 10 feet, our black metal post provides a robust and aesthetically pleasing foundation for your fence system.

Constructed from pre-galvanized Q195/Q235 steel pipe, the post combines high load-bearing capacity with excellent corrosion resistance. This construction ensures long-term stable performance across a variety of environmental conditions. Furthermore, a double layer of protective coating significantly enhances its longevity. This includes a galvanized base layer followed by a durable baked powder coating. This dual protection effectively prevents rust, UV damage, and wear, while simultaneously maintaining its sleek black appearance.

In addition, an adjustable top rail configuration enables the post to adapt effectively to various terrains. Its generous 10-foot total length ensures optimal underground anchoring for enhanced stability, with 4 feet typically buried. The remaining 6 feet above ground meet the requirements of standard fence heights. A crucial included component is the post cap. This cap not only provides a clean, finished look but also effectively prevents water seepage into the top of the post, protecting against internal corrosion.

For ease of installation, a complete hardware kit is included. This kit contains necessary components such as brackets, bolts, nuts, and screws. Furthermore, the black metal fence post features pre-drilled holes, significantly simplifying the setup process.

Production Process

Material: High-quality steel pipes or aluminum pipes, ensure that the raw materials meet the relevant standards.
Pipe Cutting: Cut according to the design requirements to form the basic structure of the Fence Post.
Whip Blasting: Cleaning and roughening the surface by spraying high-speed abrasive particles onto the surface of the workpiece through compressed air.
Surface Pretreatment: The phosphating film itself has a certain anti-corrosion ability. Chromizing forms a dense oxide film on the surface of the aluminum product.
Powder Coating: Spray epoxy-polyester powder on the surface, and cure it at a high temperature. This process makes the product more rust-proof and corrosion-resistant.
Quality Control: We will conduct a quality inspection on each product to check the strength, wall thickness, and powder coating thickness to ensure the quality stability.
Packaging: Professional transportation methods ensure the safe transportation of products.
