Iyi chiyero inoshanda kumabhiriji uye zvivakwa zvine riveted, mabhaudhi uye akasungwa zvivakwa, pamwe neyakajairwa-chinangwa structural simbi kabhoni simbi zvikamu, mahwendefa uye mbariro. ita kuti kukosha kwegoho kuderedze, nekuda kwehuwandu hwekabhoni yemukati, kushanda kwese kwezviri nani, simba, plastiki uye welding uye zvimwe zvivakwa kuti uwane mutambo uri nani, unonyanya kushandiswa.
A36 simbi ndiro kemikari yakagadzirwa:
C: ≤ 0.25, Si ≤ 0.40, Mn: ≤ 0.80-1.20, P ≤ 0.04, S: ≤ 0.05, Cu ≥ 0.20 (apo zvigadziro zvemhangura-ine simbi).
Mechanical properties:
Goho simba: ≥250 .
Tensile simba: 400-550.
Elongation: ≥20.
National standard uye A36 zvinhu zvakafanana neQ235.
