ASTM A500 raj yog tus qauv specification rau txias-tsim welded thiab seamless carbon steel structural tubing nyob rau hauv round, square thiab rectangular duab.
ASTM A500 npog txias-tsim welded thiab seamless carbon steel puag ncig, square, rectangular, los yog tshwj xeeb zoo zoo structural tubing rau welded, riveted, los yog bolted kev tsim kho ntawm cov choj thiab cov tsev, thiab rau cov qauv siv dav dav. Cov tubing no yuav tsum tau tsim nyob rau hauv ob qho tib si welded thiab seamless qhov ntau thiab tsawg thiab yuav tsum muaj cov tshuaj lom neeg ntawm carbon, manganese, phosphorus, sulfur, thiab tooj liab.
