Boka reSimbi reTianjin Rainbowinyanzvi yekugadzira mapaipi esimbi emhando yepamusoro uye yepasi rose uye mutengesi muChina, Isu tine hunyanzvi mukugadzira mapaipi esimbi ane welded frequency, mapaipi esimbi ane galvanized, mapaipi esimbi eERW, simbi inoputika yakamonera inopisa, mapaipi esimbi ane sikweya/rectangular eGCOE. Midziyo yedu yekugadzira inosanganisira mitsara mishanu yezvigadzirwa zvemapaipi esimbi, tinogona kupa matani zviuru mazana matatu nemakumi mashanu pagore. Tine muchina mutsva, hunyanzvi hwekugadzira hwepamusoro, uye sisitimu yekudzora mhando yakasimba ine seti yakazara yemidziyo yakagadziridzwa yekuyedzwa nekutarisa kubva pakuburitsa zvinhu zvisina kugadzirwa kusvika pakutakura zvinhu. Takawana chitupa cheBV neISO9001:2000. Zvigadzirwa zvedu zvinogona kusangana neASTM DIN JIS GB BS standards. Zvigadzirwa zvedu zvinoshanda kuPetroleum, simba, gasi metallurgy, kugadzira mapepa, makemikari, zvishandiso zvekurapa, ndege, boiler heat, exchange, shipbuilding, kuvaka, nezvimwewo. Zvigadzirwa zvedu zvakapararira pasi rese, zvakaita seGermany, Italy, North America, South America, Southeast Asia, Japan, HongKong neTaiwan. Chinangwa chedu ndechekunaka kwepamusoro-soro, mutengo unokwikwidzana, uye sevhisi yakanakisisa yekugutsa vatengi vedu, ticharamba tichigadzira nekugadzira zvinhu zvitsva, kuvaka kambani inovimbika uye ine mukurumbira wepamusoro pasi rose. Tinogamuchira vatengi vese vanobva kumativi ese epasi kuti vashande nesu, vagadzire uye vabatsire tese!
