FAQ

FAQs Roof Metal Decking

What are the available types of metal roof decks?

The available types are Type B (1.5" deep) for general commercial use, Type N (3" deep) for long-span requirements, and Vented Type B Deck for projects needing moisture control.

When should I use Type N roof deck instead of Type B?

Type N roof deck is ideal for long-span applications, such as warehouses or industrial buildings, where fewer supports are preferred. Type B is more common for standard commercial and industrial roofing systems.

What is the purpose of a vented Type B roof deck?

Vented Type B Deck is designed to allow moisture control, making it suitable for use in Lightweight Insulated Concrete (LWIC) applications.

What coatings are available for these metal roof decks?

All types of roof decks are available with galvanized coatings (G60, G90) for corrosion resistance or primer-painted finishes for additional protection and coating compatibility.
