Ana amfani da maɗaukakiyar halin yanzu don dumama saman ƙarfe na gida, kuma ana walda shi ƙarƙashin aikin ƙarfin waje, ba tare da
kowace waya walda ko juyi, kuma ana iya ci gaba da samarwa da yawa.
1) Faɗin ƙayyadaddun bayanai (girman sashi). Tsawon, yanar gizo, flange kauri da flange nisa za a iya zaba bisa ga abokin ciniki
bukatun ga karfe farantin waldi. Ana iya amfani da shi azaman iri-iri banda ma'auni na H-beam mai zafi.
2) Zabi nau'ikan karfe iri-iri. H-beams masu zafi sun fi Q235B da Q345B. Lokacin da kananan batches na musamman karfe maki ne
ake buƙata, masana'antar samarwa ba zata iya samar da su ba. Welding na iya zaɓar farantin karfe kamar yadda ake buƙata.
3) Samfurin yana da inganci mai kyau da inganci mai kyau. Saboda babban madaidaici da ingantaccen ingancin samfurin farantin karfe,
da H daidaici bayan waldi ne kuma high da surface quality ne kuma mai kyau. A kauri saba wa karfe faranti (amfani da waldi H-bim)
Gabaɗaya shine 'yan goma na millimita zuwa ƴan kashi goma na millimeter, yayin da kaurin kauri na H-beams masu zafi shine kaɗan na goma na wata.

5) Yana da sauƙin samun lahani na walda. Ko da yake akwai fa'idodi da yawa da aka ambata a sama, saboda yin walda, akwai ragowar walda
Damuwar zafi a wurin walda, tsarin wurin waldawa ya bambanta, kuma akwai damuwa na tsarin, wanda ke da lahani ga lahani na walda.
Tare da ci gaba da haɓaka matakin walda da matakin maganin zafi, waɗannan rashin amfani suna raguwa a hankali. A yau, high quality-welded
An yi amfani da H-beams a fannoni daban-daban ciki har da masana'antar soja da sararin samaniya.
