Deck Railings Designed to Last

If you’re looking at different deck railings and designs, you’ve probably already come across our aluminum railing system Durarail. These powder coated aluminum deck railings are some of the strongest, longest lasting deck railings available. Why do they last so long? There are three very good reasons. Their structural design, the aluminum used in their construction, and the powder coating applied afterward.

We talked earlier this month about the benefits of using aluminum, so this time let’s focus on their structural design and powder coating.

What’s so special about the design?


The aluminum alloy used in our deck railings is known as 6063-T5 which has an ultimate tensile strength of 22,000 psi. The posts are made of 6005A-T61 alloy which is even stronger with the minimum yield strength of 35,000 psi. The .070-inch wall thicknesses of the extrusions are currently the heaviest in the industry.

It’s not all about weight and alloy strength though. The manufacturing process for our deck railings is held to precise specifications. Everything fits together the way it should. There’s no need for any additional welding, or special alteration to the product to make it fit on your deck space.


The fasteners are all hidden from view. While screws and fasteners are the weak spot on almost every design, Durarail goes the extra mile to protect its fasteners from the elements. This adds considerable time to the lifespan of the product.

What’s so special about powder coating?

Powder coating resembles a painted surface, but it’s so much more than that. We detail the whole process on the Durarail page, but you can simply think of it like a polyester skin that’s much tougher than any painted surface.

Powder coating lasts for years. In fact, we’re so confident in the process that we included it as part of the Durarail limited warranty. We guarantee the powder coating will not crack, or blister of its own accord for up to 10 years!
