Classification of main and auxiliary materials for mechanical and electrical installation
Thread Content
I would like to ask the experts here how the main materials used in mechanical and electrical installation should be classified. Generally, we tend to categorize consumable items such as oxygen-acetylene gas (used for construction), grinding discs, welding materials, and personal protective equipment as auxiliary materials. But whether fasteners, expansion bolts, gaskets, wire nuts, pipe clamps, number tubes, and so on are considered auxiliary materials. Is there any document that defines the main and auxiliary materials? I would appreciate some guidance! Thank you so much!
It depends on how your contract is drafted; fasteners and gaskets are definitely the main materials
