Galvanized steel plate, channel steel, angle steel how to take samples, how to submit?

Answer:

The symmetry type (such as steel I-beam, T steel), in the distance where the interception endpoint 1/6 length long 500 mm, 20 mm wide rectangular specimens, non symmetry type steel (such as steel, L steel), in the distance where the length of the endpoint 1/3 intercept long 500 mm, the width of the rectangle 20 mm 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.

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.

Q235 pipe, PE pipe, 304L steel, stainless steel pipe, wire and cable approach, according to the same grade batch sampling representative or the same grade, the same approach specifications are to be inspected.

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. 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.
