Composite Decking Type of Nails

Composite decking is a series of boards that are made of a combination of plastic and wood fibers. It has a much longer lifespan than standard wooden decking and is very low maintenance. There are several types of composite decking nails to fasten and build structures.

Function

Composite decking nails function as the main fastener for the boards to stay in tact. Many companies specify additional joint fasteners that coordinate with the composite decking nails.

Types

There are two main types of composite decking nails. Stainless steel and double-dipped galvanized nails are strong and durable enough to endure the life of the deck and withstand the elements.

Size

Galvanized and stainless steel nails are available in a wide range of sizes. Galvanized nails range from 2 to 6 inches in length and most stainless steel decking nails range from 2 to 3 1/2 inches long.

Considerations

The nails must be able to penetrate the wooden substrate under the decking by 1 1/2 inches. The correct length of nails will depend on the thickness of the decking that is chosen.

Recommendation

Milled face hammers are abrasive and are not recommended for driving hot-dip galvanized nails because it will rub off the dipped coating on the nails and reduce their durability.
