3.Ukuqina okuhle kunye nokuqina
4. Ifanelekile kwiiprojekthi ezinzima zoshishino kunye neziseko zophuhliso
5. Ifumaneka kwiimitha ezahlukeneyo ze-H kunye nobukhulu bemitha ye-flange ebanzi

Iinkampani ezininzi zokwakha zikhethaUmqadi we-ASTM A572 Hkwiindawo zokugcina impahla, izakhiwo zoshishino, iibhulorho, kunye nezakhiwo ezinkulu zentsimbi apho kufuneka umthwalo ophezulu.

Yeyiphi i-H Beam engcono kwiprojekthi yakho?

Ukhetho phakathiUmqadi wentsimbi we-ASTM A992kwayeUmqadi we-ASTM A572 Hkuya kugqitywa ziimfuno zeprojekthi, isicelo, kunye neekhowudi zoyilo.

Umqadi wentsimbi we-ASTM A992Ngokwesiqhelo zizinto ezikhethwayo zokwakha zorhwebo zanamhlanje, ulwakhiwo oluphezulu, iiprojekthi ezineemfuno zesakhiwo ezifuna umgudu ngenxa yokudityaniswa kakuhle kunye nomgangatho ofanayo.

Xa isityalo-mveliso, indawo yokugcina impahla, ibhulorho, okanye isakhiwo esithwala imithwalo enzima sifuna amandla kunye nezixhobo zokwakha ezingabizi kakhulu,Umqadi wentsimbi we-ASTM A572uphendula umnxeba ngesisombululo esithembekileyo nesingabizi kakhulu.

Uncedo lobuchwephesha oluvela kumthengisi we-H Beam onolwazi ngobukhulu kunye nomgangatho weUmthengisi weBeam yentsimbi ye-A992 or Umthengisi we-ASTM A572 Steel BeamKunganceda kakhulu abathengi ukuba bakhethe imiqadi echanekileyo xa becinga ngemigangatho yeprojekthi.

Ukukhetha umqadi we-H ofanelekileyo

Umqadi wentsimbi we-ASTM A992kwayeUmqadi we-ASTM A572 Hziimveliso zentsimbi ezisemgangathweni ezisetyenziswa kakhulu kwihlabathi liphela kwizicelo zokwakha.
