WHAT IS TYPE B ROOF DECK?

B Deck is by far the most commonly used roof deck for new construction projects. This is due to the fact that B deck is the most efficient 1.5”deep steel roof deck section. Compared to Type A roof decks and Type F roof decks, Type B metal roof decks have the highest strength-to-weight ratio. As with all steel products, the lighter the section, the more economical it will be. And since Type B roof decks can carry higher loads at longer spans than A decks and F decks, the steel supports below the metal deck can be spaced further apart. The result? A larger support spacing results in fewer supports and more savings for the building owner.

Here is one standard B deck for your reference:

As previously mentioned, Type B deck is the most commonly used roof deck for new construction projects. In comparison to other roof decks such as Type A and Type F, Type B roof decks have a higher strength-to-weight ratio, are more economical, and can carry higher loads at longer spans. Given that steel supports can be spaced further apart with Type B decks, building owners can save money by purchasing less supports

Type B deck is a wide-rib roof deck ideal for a wide range of applications

Type B, wide-rib structural roof deck is a high-performance, cost-efficient choice with a variety of options to meet multiple project needs. Standard or cellular, acoustic or vented, interlocking or nested side laps, B deck is among the most flexible of our 1½-inch deep roof decks.

Standard B Deck

Type B roof deck provides the best balance of strength and economy of all the 1½-inch-deep roof decks. Where rigid roofing insulation is used with B deck, a minimum 1-inch thickness is required.

We design the Steel roofing decks machine as following:

Based on understanding of Type B (B-deck)Metal Roof Deck 80 (Wide Rib) understanding, we design the machine like this:

Thick cutter holder to protect the cutter holders for long time to use.

For the shaft and rollers, normally ZHONGTUO uses very strong shaft and big diameter rollers with gear inside , for making higher speed and better rolling effect.

For some heavy duty rollers, we will put gear outside, then it can feed the coil to machine easily.
