Binding buckles are designed for connecting metal bandages of thermal insulation of industrial facilities, buildings and structures. Buckles, depending on the design, are divided into the following types: I, II, III, IV.
The designation of the buckle type should include a symbol indicating the type of metal from which the buckle should be made, namely: A-aluminum alloy or aluminum, O-galvanized steel, C-thin-sheet roofing steel.
The type of metal from which the buckle should be made must correspond to the thermal insulation project developed by a specialized organization.
Type of climatic design made of thin-sheet roofing steel (C) – YI according to GOST 15150-69.
