Main structural steel ---- ---- resistant steel alloy carbon steel ---- ---- ---- cold steel ----- weathering steel tool steel - a variety square steel - steel billet - Billet round is the circular cross-section solid bar of steel. The specifications of a few millimeters in diameter, such as "50" means that the 50 mm bar diameter. Round into hot-rolled, cold-forging and drawing three. Rolled round specifications of 5.5-250 mm. Which :5.5-25 mm small round mostly straight bundles supply, used for steel, bolts and various mechanical parts; greater than 25 mm round steel, mainly used in the manufacture of mechanical parts or for seamless steel round billet Other steel with distinction: a different shape, round shape light round, no pattern without ribs, other steel surface appearance Sculptured or ribs, thus causing a small bar and concrete bond strength, and adhesion of other large steel and concrete. 2 ingredients are not the same, round (a steel) belonging to the ordinary low-carbon steel, alloy steel other than reinforcement. 3 is not the same intensity, low round strength, other high strength steel, the same size in diameter as compared with other steel bar, round bar can withstand tensile steel than other small, round plastic but stronger than other steel that pulled off the first round in a larger deformation, while the other pulled off in front of steel deformation is much smaller. Standard Standard round of: (GB699-1988, GB700-1988, GB3077-1988, GB702-1986, QJ/HG02.17-1991). Materials are: 20 #, 35 #, 45 #, Q235, Q235B/C/D/E, Q345, Q345B/C/D/E, 20Mn, 35Mn, 45Mn, 65Mn, 12CrMo, 20CrMo, 15CrMo, 35CrMo, 42CrMo, 35CrMoV, 5CrMnMo, 20CrMnMo, 40CrMnMo, 20CrNiMo, 40CrNiMo, 20CrMnTi, 30CrMnTi, 16MnCr5, 38CrMoAL, GCR15, 09MnD, 34CrMo4, 35CrMo4, 42CrMo4, P11, 10CrMo910, 20Cr2Ni4,,,,, the Company's inventory, timely delivery, Special custom specifications short cycle. The operating philosophy: customer focus, quality as the fundamental, credit for life operating principle: honesty Shiyibuque fight the market, create competition among marketing and development company committed to yourself: a quality assurance purchase directly from regular factory, in strict accordance with supplier quality standards required by the user, and in the end responsible for the quality of the material does not match the refund, replacement, Baopei.
