Galvanized steel plate, channel steel, angle steel how to take samples, how to submit?
Mainly look at the drawings design requirements, if required, ask the local Quality Supervision Bureau and other inspection bureau, how to detect, they will explain how to take the process.
Sampling requirements: symmetry type steel (such as steel, T steel), in the distance where the interception endpoint 1/6 length long 500 mm, 20 mm wide rectangular healthy specimens, non symmetry type steel (such as steel, L steel), in the distance where the endpoint 1/3 length of 500 interception mm, 20 mm wide rectangular specimens. Direct interception of local plate in from the outer ends of the 12.5 mm long 500 mm, 20 mm wide rectangular specimens. Take one for tensile test and one for cold bending test.
Galvanized steel plate, channel steel, angle steel how to take samples, how to submit?Each batch of 60t of the same raw material, the same batch number, the same grade, the same variety, the same size and the same delivery status is used as a batch.
