Imakethi ye-H ye-beam yehlabathi imiselwe ukuba ibone ukukhula okubonakalayo kule minyaka izayo, ikhuthazwa kukwanda kwemfuno kumacandelo okwakha kunye neziseko zophuhliso.I-H beam, eyaziwa ngokuba yi-H-icandelo okanye i-wide flange beam, yimveliso yentsimbi esetyenziswa ngokubanzi ekwakhiweni kwezakhiwo, iibhulorho kunye nezinye izakhiwo ezinkulu.
Ngokwengxelo yophando lwamva nje lwemarike, imfuno ye-H beam kulindeleke ukuba ikhule ngesantya sokukhula ngonyaka (CAGR) ngaphezulu kwe-6% ukusuka ngo-2021 ukuya ku-2026. kumazwe asakhulayo anjengeTshayina, iIndiya, kunye namazwe akuMzantsi-mpuma weAsia.Ukwakhiwa kwezakhiwo ezitsha zokuhlala kunye nezorhwebo, kunye nokulungiswa kunye nokwandiswa kweziseko ezikhoyo, ziqhuba imfuno ye-H beam kule mimandla.
Enye yezinto eziphambili zokuqhuba ukukhula kwemakethi ye-H kukwanda kokwamkelwa kwentsimbi njengesixhobo sokwakha.Intsimbi inika iingenelo ezininzi ngaphezu kwezixhobo zokwakha zemveli ezifana nekhonkrithi kunye neenkuni, kubandakanywa umlinganiselo ophezulu wobunzima bobunzima, ukuqina, kunye nokuphinda kusetyenziswe.Ezi zakhiwo zenza i-H ibem ibe lukhetho olunomtsalane kubakhi kunye neekontraka ezijonge ukwakha izakhiwo ezomeleleyo nezisebenzayo.
Ngapha koko, ukuguquguquka kwe-H beam kwenza ukuba ilungele uluhlu olubanzi lwezicelo kushishino lokwakha.Uyilo lwayo olubanzi lweflange lubonelela ngezakhono ezibalaseleyo zokuthwala umthwalo, okwenza ukuba ilungele ukuxhasa imithwalo enzima kwizakhiwo ezinkulu kunye neebhulorho.Ukongeza, umqadi we-H unokwenziwa ngokulula kwaye ulungelelaniswe ukuhlangabezana neemfuno ezithile zeprojekthi, ukubonelela ngokuguquguquka kubakhi bezakhiwo kunye neenjineli ekuyileni izakhiwo ezizodwa kunye nezintsha.
Ukongeza kusetyenziso lwayo ekwakhiweni, i-H beam ikwafumana izicelo kwamanye amashishini afana nokuvelisa kunye neemoto.Icandelo leemoto, ngakumbi, liqhuba imfuno ye-H beam njengoko isanda kusetyenziswa ekuveliseni i-chassis yezithuthi kunye nezakhelo.Amandla aphezulu kunye nokuqina kwe-H beam kwenza kube yinto efanelekileyo yokuqinisekisa ukunyaniseka kwesakhiwo kunye nokhuseleko lwezithuthi.
Ngaphandle kwembono entle yentengiso ye-H beam, kukho imingeni ethile enokuthi ibe nefuthe ekukhuleni kwayo.Ukuhla kumaxabiso ezinto ezikrwada, ngakumbi intsimbi, kunokuchaphazela ixabiso lemveliso lilonke kunye namaxabiso eemveliso ze-H.Ukongezelela, iinkxalabo zokusingqongileyo ezinxulumene nokuveliswa kwentsimbi, ezifana nokukhutshwa kwekhabhoni kunye nokusetyenziswa kwamandla, kunokuchaphazela imfuno yeemveliso zensimbi ezibandakanya i-H beam.
Ukujongana nale mingeni, abavelisi batyalomali ngokwandayo kwinkqubela phambili yetekhnoloji kunye nenkqubo entsha yokuphucula ukusebenza kakuhle kunye nokuzinza kwemveliso ye-H.Oku kubandakanya ukwamkelwa kweendlela eziphambili zokuvelisa kunye nokusetyenziswa kwentsimbi ehlaziyiweyo njengento ekrwada, enokunceda ukunciphisa impembelelo yokusingqongileyo yemveliso ye-H.
Lilonke, imakethi ye-H beam ilungele ukukhula olomeleleyo kule minyaka izayo, iqhutywa kukunyuka kwemfuno yentsimbi kulwakhiwo kunye neeprojekthi zeziseko zophuhliso.Ngogqaliselo oluqhubekayo kuphuhliso oluzinzileyo kunye neendlela zokuvelisa izinto ezintsha, ishishini le-H beam kulindeleke ukuba liqhubeke nokuvela ukuze lihlangabezane neemfuno eziguqukayo zemarike yokwakha yehlabathi.
