Metal deck can be used in a variety of ways, but one of the most common uses for metal deck is for roofing. When you are sourcing metal deck for a roofing project, it is important to know which type of deck that you need. This guide will help you understand the different types of roof decking, and when to use them.
What Is Metal Roof Deck?
Metal roof deck is an essential part of many commercial and industrial construction projects. It is a strong sheet of metal that is formed to fit the needs of specific projects. It can be used for flat, pitched, and arched roofs. In some cases, when the bottom of the metal deck is intentionally left exposed, it may even be painted to create a more polished and finished look.
Metal roof deck serves as the base of the roofing system. Once the sheet of metal decking has been laid down, the rest of the roofing system can be built on top of or around it. This keeps the metal roof deck safe from natural elements like wind or rain, and ensures that the structure is safe and sturdy for many years to come.
Types of Roof Decking
All types of roof decking can be created in a variety of depths, widths, and gauges depending upon the needs of the construction project. The most common types of roof deck are A Deck, B Deck, F Deck, N Deck, and 1″ Roof Deck.
A Deck is a narrow rib, 1.5 inch deep metal deck offering. It is the oldest type of metal roof deck, and is not commonly used in construction today because it has one of the lowest strength-to-weight ratios of all types of metal roof deck. Typically, A Deck is used to repair the roofs of older buildings in order to match the existing style.
B Deck, which is also referred to as BW-36, Wide Rib, 1.5B, BI, BV, or BIV, is a wide rib, 1.5 inch deep metal deck. It the most modern and most common type of metal roof decking. It is very lightweight and easy to install, making it an economical choice for many construction projects. Typically, B Decking is the ideal solution for short to medium span applications in roof, canopies, and awning construction. It is used as part of roofing systems to support rigid board insulation and built-up roofing.
F Deck is the last of the 1.5 inch deep metal deck types. F Deck is also referred to as F-36, Intermediate Rob, and 1.5F. It is an intermediate rib metal deck, with a rib size in between A Deck and B Deck. The exact rib dimension will depend on the manufacturer. Its unique rib size helps support the installation of board insulation because it is less likely to crack during installation with people walking on the insulation. F Deck is not as strong as B Deck, so it is typically recommended for roof deck repairs or re-roofing projects, and is most cost-effective for small roofs, canopies, or awnings.
N Deck is a long span, 3 inch deep metal deck. It is also called Deep Rib and 3N. Much like B Deck, it is a lightweight and easy to install choice for commercial and industrial construction projects. Typically, N Decking is used for applications in roof, canopies, and awning construction when you have supports that are far apart.
1″ Roof Deck
1″ Roof Deck is a sturdy choice with 1 inch deep ribs. It is similar to N Deck in its uses, but rather than long span support, it is the ideal solution for short to medium span applications. It may also be referred to as 1.0C, HD, CF 7/8”, HF, UF1X. 1″ Roof Deck can be used in roof, canopies, and awning construction.
