Answer for USA, Canada and countries running a 60 Hz supply service.
I've checked the NEC and there is no required material specific to Cellular CONCRETE Floor Raceways. It defines this as an "enclosed tubular space in a floor made of precast cellular concrete slabs." Headers, which would be the accesses to the cells, are defined as metal raceways.
Cellular METAL Floor Raceways are, by definition, metal.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What else can I help you with?
Is copper a metallic element?
Yes, copper is a metallic element. It is known for its excellent electrical conductivity, malleability, and corrosion resistance, making it a popular material in various applications including electrical wiring, plumbing, and construction.
Is aluminum oxide metallic?
Aluminum oxide is not considered metallic because it is a ceramic material. It is a compound formed between aluminum and oxygen, and it exhibits properties such as high hardness, electrical insulation, and thermal resistance.
Electrons free to move throughout a material are associated with a what?
It is metallic bond, because you know yea metallic is metal and meteal collect electric, so it mean it free to move so the electricity pass through the meatal and when u tough it you may die exacly.
What type of compound contains metallic bonds?
Metallic compounds contain metallic bonds, where electrons are delocalized and free to move throughout the material, leading to properties such as high electrical conductivity, malleability, and ductility. Examples include metals like copper, iron, and aluminum.
What type of bond doe Cu3Zn2 have?
Cu3Zn2 likely has metallic bonds, as it is a solid solution of copper and zinc with metallic properties. In metallic bonds, electrons are delocalized and free to move throughout the structure, giving the material its characteristic properties such as electrical conductivity and malleability.
Is a glass lens a conductor or insulator?
A glass lens is an insulator as it does not conduct electricity. It is a non-metallic material that does not allow the flow of electrical charge through it.
What is the characteristics of metallic material?
Metallic materials typically have high electrical and thermal conductivity, luster, malleability, ductility, and are typically opaque. They also tend to have high density, strong bonding between atoms, and good mechanical properties.
Which non metallic solid is not an electrical insulator?
graphite
Is Golds bond type covalent or ionic?
Gold's chemical bond type is metallic, not covalent or ionic. In metallic bonding, electrons are delocalized and free to move throughout the material, creating properties such as malleability and high thermal and electrical conductivity typical of metals like gold.
What is Electrical sheathing?
Electrical Sheathing is various forms of metallic or non-metallic covering over conductors. Nonmetallic-Sheathed Cable is what is known by the brand name Romex.
What is the definition of metallic solid?
Metallic solid is the meaning of a certain alloy that was probably originally liquid but was then manufactured to become a solid metallic alloy. But in non nerd details; a metal liquid turned into a solid metal.
Is a glass bottle a conductor or a insulator?
A glass bottle is an insulator, meaning it does not conduct electricity easily. Glass is a non-metallic material that has high electrical resistance, making it a poor conductor of electricity.
