3. Kushivirira Kwakasiyana: RHS SHS CHS Simbi Saizi uye Kusiyana
Kunze kwemakemikari esimbi, misiyano chaiyo muRHS SHS CHSsaizi dzesimbi uye saiziraira kubudirira kwezvikamu zve modular zvakanyatsonaka uye otomatiki fit-ups panzvimbo. Kune ma profiles asina chinhu ane urefu hwepadivi (b, h) mukati me100 mm-200 mm, geometric tolerances inoratidza misiyano yakasiyana:
Kushivirira Ukobvu hweMadziro:EN 10219 inotsanangura kushivirira kwe ±10% kumaprofayiri akasungirirwa (ane muganho wepamusoro wakavharirwa pa ±2mm), nepo GB/T 6728 ichibvumidza kushivirira kwakajairika kwe ± 10% kunobvumira ukobvu hwemadziro hwakaderera zvichienderana nezvikamu zvakati wandei.

4. Kuvimbisa Hunhu: EN 10204 3.1 MTC uye Kutevedza Kugadzirwa kweNhamba dzeKupisa
Pakutevedzera mapurojekiti epasi rose, magwaro anosimbisa kwakabva zvinhu zvakakoshawo sehunhu hwazvo. Kutumira zvinhu zvinoenderana nezvinodiwa kunoda kuongororwa kwakanyatsojeka.
Pasi pekutenga kwakaitwa neEurocode, vagadziri vanofanirwa kupa gwaro rakasimbiswa zvizereEN 10204 3.1 Chitupa Chekuyedza Zvinhu (MTC)Gwaro iri rinovimbisa kuti kuongorora makemikari nenzvimbo dzekuyedza zvemakanika zvinotevedzera mwero chaiwo wakumbirwa.
Zvichienderana nezvinodiwa nemakambani epasi rose eEPC, kuvimbiswa kwemhando yepamusoro mufekitori yehunyanzvi inotenderera ichivharirwa muchokwadi chekuti hunhu hwesimbi hunotemerwa chete nesimbi huru. Saka, kutonga kwemhando yepamusoro kunoshanda paYuantai Derun Group.zvakabatana zvakananga nenhamba yekupisa yezvinhu zvisina kugadzirwa.
Kuti ive nechokwadi chekuti yasimbiswa zvizere panzvimbo yeprojekiti, EN 10204 3.1 Material Test Certificates inoenderana ichatumirwa pamwe chete nemagwaro ekutumira nezvinhu zvinotakura, zvichienderana neHeat Numbers chaiyo inoratidzwa pamatagi ezvigadzirwa. Maitiro aya ekunyora magwaro anovimbisa kuti vaongorori veminda vanogona kuona nekukurumidza kuumbwa kwemakemikari uye kuongororwa kweladle vachipesana nebhiri rezvinhu zvako, zvichibvisa mipata yemagwaro inowanzo dzivisa kuongororwa kwenzvimbo dzepasi rose.
5. Kutevedzera Mutemo weMabhizinesi: Kumaka CE uye Kudzora Njodzi Dzinodzivirira Kurasa Marara
Kugamuchirwa kwezvinhu kunonyanya kukanganiswa nekuderedza njodzi dzekutengeserana, miganhu yekufambisa zvinhu, uye mitemo yekutengeserana kwenyika dzese.
Chipingamupinyi chikuru mukutsvaga zvinhu zvakasiyana-siyana igwaro renyika. Mapurojekiti anosungirwa nemitemo yeEuropean Union anoda gwaro repamutemoMucherechedzo weCE wezvikamu zvesimbi zvine maburiKana mugadziri asina ongororo yeFactory Production Control (FPC) inofanirwa kupihwaEN 10219Kana chiratidzo cheCE chasvika, kuenzana kwehunyanzvi kunova kusina basa pamutemo patsika.
Yuantai Derun Group inobata zvizereKumaka kweCE (EN 10219-1), BC1 (Singapore)uyeISO 9001/14001/45001zvitupa, zvichibvumira kubvumidzwa zviri nyore muzviteshi zveEurope nepasi rose.
