Our metal roof beam features hiah tensile strenath, lts body is welded by automatic submerged arc weldingThe weldina auality is hioh: performance is stable: and production efficiency is hiah, Usina automatic submeraecarc weldina can weld a steel plate with the thickness less than 14mm and without aroove in one time. t also helpsto reduce the welding deformation and effectively prevents overheating of the metal near the weld zone.To improve the comprehensive mechanical properties of our product, the articulated roof beam body andparts are made of 27$ilMn and processed by quenching. The long line beam is treated by the GT intermediate fre-quency induction heating furnace which has strong continuous working abilit, high heating speed, less oxygen de-carbonization, and high precision temperature control, thus effectively avoiding uneven hardness. In addition, ourcompany is the only one in China that has intermediate frequency production line reaching 7M.
