Iyo Yuantai Derun's square hollow chikamu, rectangular hollow chikamu, denderedzwa hollow chikamu, pre galvanized simbi pombi, inopisa-dhip galvanized simbi pombi uye zvimwe zvigadzirwa zvinotakura EN10210, EN10219, ASTM A53, ASTM A500, ASTM A501, ASTM A106, BSS187 STKR400,JIS STKR490, GB/T700-2006,GB/T6728-2002; Kaviri mativi akanyura arc spiral simbi pombi, uye isina musono simbi pombi inotevedzera GB / T9711-2011, API Spec 5L uye API 5CT zviyero zveChina petroleum indasitiri.
Kambani yeYuantai inokoshesa zvakanyanya kumhando yezvigadzirwa, inodyara zvakanyanya mukuunzwa kwemidziyo yepamusoro uye nyanzvi, uye inoenda kunze kuzadzisa zvinodiwa nevatengi kumba nekune dzimwe nyika. Muna 2023, Yuantai Derun boka rabhoritari rakapfuura CNAS certification.
Iyo Steel hollow chikamu chekuyedza zvirimo zvinogona kukamurwa kuita: kuumbwa kwemakemikari, goho simba, kusimba simba, kukanganisa midziyo, nezvimwe.
Panguva imwecheteyo, kambani inogona zvakare kuita pa-line kukanganisa kuona uye annealing uye mamwe maitiro ekurapa kupisa zvinoenderana nezvinodiwa nevatengi.
