Stee H Beam
Mabala a tla ka libopeho le boholo bo fapaneng.Beam ea kaho ke karolo ea sebopeho e jarang moroalo ka ho hana ho kobeha ho tloha ho matla a tlase.Bophahamo ba eona bo rapameng bo pharaletse haholo ho feta bophara kapa botebo ba eona.Libalaka li khetholloa ka boemo ba tsona, bolelele le thepa.Mefuta e tloaelehileng haholo e tšoana le Capital I kapa Capital H. Ka kakaretso e sebelisoa ho haha, boenjiniere ba sechaba, mechine e boima, kaho ea literaka le mesebetsi e meng e boima.Beam e sebelisoa haholo ho ts'ehetsa meaho e boima.Beam e fumaneha ka mefuta ea Aluminium, Stainless Steel le Hot Rolled.
