"W" muzita reW beam inomiririra "wide flange." Musiyano mukuru uripo pakati peW beams ndewekuti nzvimbo dzadzo dzemukati nedzekunze dzeflange dzakafanana. Uyezve, kudzika kwese kwebeam kunofanirwa kunge kwakaenzana nehupamhi hweflange. Kazhinji, kudzika kwacho kwakakura zvakanyanya kupfuura hupamhi.
Chimwe chinhu chakanaka pamusoro peW beams ndechekuti flanges dzakakora kupfuura dandemutande. Izvi zvinobatsira kudzivirira kumanikidzwa kwekukombama.
Zvichienzaniswa nematanda eH, maW-beams anowanikwa muzvikamu zvakajairika. Nekuda kwehukuru hwawo hwakakura (kubva paW4x14 kusvika paW44x355), anoonekwa sematanda anonyanya kushandiswa mukuvaka kwemazuva ano pasi rese.
A992 W beam ndiyo nzira yedu inonyanya kutengeswa.
danda reH

Matanda eH ndiwo matanda makuru uye anorema kupfuura mamwe ese aripo, anokwanisa kutakura zvinhu zvinorema zvikuru. Dzimwe nguva anonziwo maHP, maH-piles, kana kuti mapills anorema, zvichireva kushandiswa kwawo sezvitsigiro zvepasi pevhu (makoramu anorema) zvezvivakwa zvakakura nezvimwe zvivako zvikuru.
Kufanana nematanda eW, matanda eH ane nzvimbo dzemukati nedzekunze dzakafanana. Zvisinei, upamhi hwedanda reH hunenge hwakaenzana nehupamhi hwedanda. Danda racho rine ukobvu hwakafanana mukati mese.
Mumapurojekiti mazhinji ekuvaka neinjiniya, matanda anoshanda sehwaro hwekutsigira. Iwo ingori mhando yesimbi yekuvaka, asi sezvo paine mhando dzakasiyana dzematanda dziripo, zvakakosha kukwanisa kusiyanisa pakati pawo.
Wakadzidza zvakawanda nezve H beams ne W beams mushure mekusuma kwanhasi here? Kana uchida kudzidza zvakawanda nezvehunyanzvi hwedu, ndapota taura nesu kuti tikurukure.
