N'oge na-adịbeghị anya, site na ọganihu na-aga n'ihu nke mmepe obodo yana ngwa ngwa nke ọrụ akụrụngwa ndị bụ isi, ọchịchọ maka ígwè arụ ọrụ dị elu abawanyela. N'etiti ha,H-beam, dị ka a isi ibu-ebu akụrụngwa na-ewu oru ngo, aghọwo a isi ọkwọ ụgbọala maka ịkwalite elu-edu mmepe nke-ewu ụlọ ọrụ, na ya magburu onwe n'ibu Njirimara na mbara ngwa ndapụta na-eduga ọhụrụ omume na ahịa.

N'ime nnukwu ụlọ obibi dị elu na East China, otu ogbeHEB 150 H-ọkụetinyela ya n'oge na-adịbeghị anya n'ime ihe owuwu bụ isi. Dị ka ọkọlọtọ European ọkọlọtọ H-beam nlereanya, HEB 150 na-akwado site na ihe owuwu maka imewe nkebi ya guzozie eguzozie, ike ekwe iguzogide na ike ibu ibu. "E jiri ya tụnyere akụkụ ígwè omenala, HEB 150 nwere ike ibelata ọnụ ọgụgụ nkwonkwo mgbakọ site na 30% n'ime usoro ihe owuwu, na-ebelata oge ihe owuwu ahụ ma na-ahụ maka nchekwa nhazi," ka onye isi ọrụ nchịkwa kwuru. Ngwa a abụghị naanị na-enyocha uru bara uru nke ngwaahịa H-beam ọkọlọtọ na-ewu ụlọ, kamakwa na-enye ntụaka maka nkwalite nchara nchara na ụlọ ọrụ ahụ.

Ọ bụ ezie na a na-eji ụdị ọkọlọtọ eme ihe n'ọtụtụ ebe,ngwaahịa H-beam dị elunọchitere anya yaASTM A572-50 H ọkụna-emekwa ka ntinye ha banye n'ọrụ ndị bụ isi. Aghọtara na ASTM A572-50 H beams nwere ezigbo okpomọkụ siri ike na nguzogide corrosion, na ike mkpụrụ ha nwere ike iru karịa 345MPa, nke dabara adaba maka nnukwu ụlọ akwụkwọ, àkwà mmiri awara awara na ọrụ ndị ọzọ nwere nnukwu ihe achọrọ.

Na mgbakwunye,ASTM A572-50 obosara flange doo, dị ka ihe mmepụta nke H-beam, agbasawanyewo ngwa ngwa nke H-beam na ụlọ ọrụ ihe owuwu. Site na obosara flange ya sara mbara, ụdị osisi a nwere ike kesaa ibu ahụ nke ọma ma melite nkwụsi ike nke nhazi ahụ.
