• NOTE 1: Boron must be less than 0.0008% according to the Central American SAC Tariff system.
• NOTE 2: If you wish to purchase galvanized sheet with a different specification than the one in table No. 1, you must do so using the form FRM-0AI00003-15 Request for exception to a standard, according to the standard. EO-0AI00003-07 Non- compliance with standard.
• NOTE 3: Reference standard ASTMA653 / A653M, designation CS type B, coating designation Z120 (G40).
• NOTE 4: The designation CS type B means that it is a coil of galvanized cold sheet for the manufacture of pipe.
• NOTE 5: For TUBAC in coating it will be used as follows
*Thicknesses equal to or less than 1.5mm: Z120 coating will be used
*Thicknesses greater than 1.5mm: Z180 coating will be used
*ASTM A924 Standard (FOR COIL DIMENSION SPECIFICATIONS)
