Aluminum box culvert, the premier replacement of concrete culvert

Aluminum box culvert in final shape

Compared with conventional concrete box culverts, box culverts do little damage to the environment, especially environmentally sensitive streams. Aluminum box culverts are not affected by the extreme weathers, such as frost weather, eliminating regular and expensive maintenance. They also have short delivery time, economic cost, and easy installation and free maintenance.

Lightweight
Lightweight of structural plate box culverts is a vital benefit of easy handling. For similar volume, the weight of aluminum accounts for 2% of concrete pipe and 1/3 of steel structure.

Easy installation
Aluminum structural plates can be preassembled not at the final installation place to significantly shorten the handling time. Lightweight makes the plates easy to handle at the installation plate.

Long life span
Aluminum alloy form a thin but tough surface barrier when exposed to oxygen. This barrier is not easy to damaged or removed by harsh environment conditions. A great number of studies and researches have proven that aluminum drainage products have at least 75 year service life for 0.1 inch-thickness aluminum plate. In salt water area like coastal areas, granular backfill materials around the structure will not reduce but enhance performance.

Friendly to environment
installation of aluminum box culvert reduce or abandon the use of conventional building materials, such as cement, sand, gravel, wood. And its delivery time is much shorter. All these factors contribute to little damage to environments.

Aluminum box culvert used as a bridge, which will significantly decrease bridge budget but will enhance the performance.
