We can manufacture any aluminum mailbox for you, including cast aluminum mailbox parts, aluminum mailbox post. You can understand our service by the following words: aluminum mailbox, cast aluminum mailboxes.


We manufacture custom aluminum mailboxes and aluminum mailbox components for residential communities, villas, commercial buildings, and public infrastructure projects. Our production scope includes aluminum mailbox bodies, cast aluminum mailbox doors, aluminum mailbox posts, and structural mailbox parts. All mailbox products can be manufactured according to customer drawings, technical specifications, or project requirements.


Mailbox dimensions can be fully customized. The common size range for aluminum mailboxes includes widths from 200 mm to 600 mm, heights from 250 mm to 500 mm, and wall thickness from 2 mm to 6 mm depending on structural strength and installation requirements. Aluminum mailbox posts and mounting brackets can also be produced with customized heights and wall thickness to match different installation environments.


Our mailbox components are manufactured using aluminum die casting, gravity casting, and CNC machining processes to ensure dimensional accuracy and consistent product quality. Additional machining operations such as drilling, tapping, and precision trimming can be completed according to the assembly requirements of the mailbox structure.


Multiple surface finishing options are available to meet outdoor durability and architectural appearance requirements. These include powder coating, anodizing, electrophoresis coating, and sandblasting surface treatment. Powder coating colors can be customized based on RAL color standards, allowing mailbox products to match different building designs or project color specifications.


For custom mailbox production, the minimum order quantity generally starts from 100 to 300 pieces, depending on the product design and mold requirements. Sample production normally takes 7 to 15 days, allowing customers to confirm the structure, dimensions, and surface finish before mass production.


After sample approval and order confirmation, the standard production lead time is approximately 25 to 35 days, depending on order quantity, tooling preparation, and surface treatment processes.

FAQ

Do aluminum mailboxes rust?

Aluminum mailboxes are both strong and durable, as well as beautiful and lightweight. If they have a powder coated finish that helps them last longer, they usually do not corrode or rust.

Which is better, plastic mailboxes or metal mailboxes?

Plastic is naturally rust resistant and relatively easy to maintain, but it is not the best choice for climates prone to extreme heat. Cast aluminum and galvanized steel are more durable options, and they both offer excellent rust resistance.

Are aluminum mailboxes magnetic?

While mailboxes are available in a variety of materials, aluminum is one of the most common. Aluminum is strong, lightweight, ductile and magnetic.

Do aluminum mailbox installations require concrete?

Concrete will provide a strong and stable foundation; however, it is not required. Once the concrete is dry, additional dirt can be distributed on top of the concrete and around the mailbox. If you want to forgo using concrete, another option is to fill the remaining depth of the hole with dirt.

How deep underground should mailbox posts go?

A 4" x 4" wooden stand or a 2" diameter standard steel or aluminum pipe.

Avoid hard and potentially dangerous supports such as heavy metal pipes, concrete posts and agricultural equipment (e.g., milk cans filled with concrete).

Bury your post to a depth of no more than 24 inches.

How do you clean a cast aluminum mailbox?

Most cast aluminum mailboxes feature a powder-coated finish or a layer of clear protective coating to keep them looking new. Allow the mailbox to air dry, and it should look as good as new in no time.
