Tianfeng Machinery developed the automatic roll forming lines for assemble silos' currugated panel, legs and roofs independently, which reached the advanced world level. The roll forming, punching and curving parts are controlled by PLC. With fine position accuracy of holes, the profiles have a good interchange- ability for easy assemble. All of these enhance the tightness of silos for good quality and reliability. The silos made by our machines totally comply with the national standard GB50322-2011<CODE FOR GRAIN STEEL SILOS>. The interchangeability and quality leads top level in the world, the silos’ service life is up to 30-50 years.
