Basically, protected steel construction. TYPE IIA (ISO 4): The main structural elements of the walls are masonry or concrete.
What is the difference between construction type IIA and IIB?
Construction Types IIA and IIB are also noncombustible, but have little to no fire resistance. Type IIA has a minimum of 1 hour fire resistance throughout. Type IIB, although noncombustible, has no requirements for fire resistance, unless required by other sections of the code.
What are the 5 construction types?
Buildings can be categorized into five different types of construction: fire-resistive, non-combustible, ordinary, heavy timber, and wood-framed.
Is there such a thing as a type IIa diamond?

Here’s what they—and you—need to know. Muscles are made up of multiple motor units. Each one contains a bundle of nerves and fibers.
Are there fire resistance requirements for Type IIB?
It’s a very commonly used construction type and Type IIB has no fire resistance requirements for any of the building elements, provided that there is adequate fire separation distance, as laid out in Table 602.
What kind of structure does a Type Ia diamond have?
The diamond class Type Ia is the compound element structure in most colorless stones. The addition of Nitrogen atoms in Type Ia diamonds is always in clusters that appear throughout the stone.
