When people think of metal decking, they think of commercial buildings and large-scale projects like shopping malls and apartment buildings. But the use of metal decking, such as B-decking, has become increasingly common in smaller-scale projects, too, like porches, patios, and small buildings.  

Metal decking is becoming an attractive option for homeowners and project managers alike because of its durability, ease of installation, and low maintenance requirements. Metal decking is often used in place of wood decking in high-traffic areas or where aesthetics is a concern. 

It is a popular choice for outdoor living spaces and exercise equipment, but many people don’t realize that the material is used to build structures, too. Instead of wood, metal is often used to build decks, fences, and other structures due to its strength and ability to withstand the elements.  

Metal decking is typically fabricated using a common process called hot-dip galvanizing, which coats the deck in a zinc chromate coating. This process is performed using a large-scale industrial machine, which applies the coating in one continuous process.  

This process is particularly suited to large-scale commercial applications, as it is relatively inexpensive to operate. 

It is perhaps the most common and widely used of all the metal building components. It is commonly available in various profiles or shapes determined by the intended use for the decking.  

From the most basic shapes like squares and rectangles to more unique profiles, like the diamond and the trapezoid, there’s a profile out there that will work for almost any project.

Types of Profiles Used in Metal Decking  

N-Deck 

The N-deck is a strong and sturdy profile often used in buildings. It has three rows of nubs along the top of the profile, which helps stabilize the deck and provide a durable surface. N-decks are typically constructed from an iron alloy and is more durable than wood.  

It is commonly used on buildings and bridges and is often constructed using the hot-dip process. This process can provide an aesthetically pleasing and corrosion-resistant finish. The N-deck also has an ideal thermal conductivity, meaning it absorbs and conducts heat far better than wood. That makes it ideal for hot days and cold nights.  

This type is durable and low maintenance, making it a popular choice for building projects – and it is available in four thicknesses: 2”, 3”, 4”, and 5”. N-decks are available in various colors, including stainless steel, and come in square, rectangular, diamond, and trapezoid shapes. They are also available in pre-painted or unpainted versions.  

The N-deck is available in various pre-cut sizes and can be ordered through custom trim suppliers. 

A-Deck 

The A-deck is also available in square, rectangular, diamond, and trapezoid shapes similar to the N-deck. The A-deck is available in several thicknesses: 3”, 4”, 5”, and 6”, and comes in the same colors as the N-deck. The A-deck is constructed from an alloy and can be painted or left unpainted.  

You can use it in a wide variety of building projects, such as patios, decks, and fences, and it is available in a variety of pre-cut sizes ordered through custom trim suppliers. The A-deck is available in a variety of colors, as well. 

F-Deck 

The F-deck is a more economical choice for anyone using them as roofing materials. They are cheaper, especially in small roofs, canopies, and awning projects. F-decks are perfect for roof deck repairs and re-roofing projects because of their advanced durability and sturdiness.  

Homeowners and building contractors usually prefer the galvanized finish for F-decks because they are more resistant to rust and aggressive interior environment. Thus, a galvanized finish can protect your metal decking longer than prime-painted ones.  

However, if the environment is not too harsh, prime-painted finishes will work to protect your metal decking long enough, beginning from installation until your home is fully renovated. In addition to the type of finish, there are other factors to consider, such as the thickness of the metal decking and the size and type of application (such as the surface type or the type of material being applied to the decking). 

B-Deck 

The B-deck is a less expensive alternative to the F-deck. It is ideal for decks and fences and comes in various cuts and thicknesses to meet almost any need. The B-deck is extremely versatile and can be applied to many different surfaces. It is a great choice for any homeowner looking for a more budget-friendly way to create a beautiful and durable outdoor area.  

Since it’s so versatile, you have many options for choosing the type of material to be used, the finish, and the size. In most cases, the B-deck is the best choice for your projects, as you can easily and quickly install it. Because of all these qualities, they have become the most common structural metal decking in the industry, ideal for short to medium-span conditions.
