We Do Docks

Since 1956


Easy to Install

Alumi-Span sells a number of devices and components that not only reduce installation times, but also make it much safer and easier to install your boat dock.



Alumi-Span offers a variety of unique accessories that add convenience and function to your boat dock.



We sell all of our individual components right down to the nuts and bolts. These can be very useful for modifying or upgrading your existing boat dock.



Since 1956 Alumi-Span has been a name that people trust.  Whether it’s a complete boat dock system or the individual components, we manufacture our products using quality methods and materials.  Best of all, Alumi-Span means “Made In America.”  Forget cut rate boat docks or the cheap Chinese parts normally found on the internet.  Many Alumi-Span boat docks are still in use after more than 50 years!  That’s values you can depend on.

With the high quality and dependability of Alumi-Span, it’s no wonder so many property owners in Michigan have selected our docks over the years. In Detroit and the surrounding area we have built a reputation you can depend on, too.
