Mahlaseli a H bakeng sa Sistimi e Tsitsitseng ea ho Kenya Letsatsi
Re sebetsa haholo le bahlahisi ba bangata ba etellang pele lefatšeng ba ho latela matla a letsatsi le ba foreimi ho ba thusa ho ntlafatsa boholo ba bona le ho fokotsa litšenyehelo tsa thepa. Ka ho sebetsa le rona, bafepedi ba ka ntlafatsa litheko tsa lihlahisoa tsa bona le kemiso ea ho tlisa thepa ho netefatsa melemo ea tlholisano.
Thepa ena e entsoe ka H-beam e pharaletseng ea Amerika e nang le maemo a tloaelehileng a ASTM A6. Sehlopha sa tšepe se ka khethoa pakeng tsa ASTM A572 GR50 /GR60, ASTM A992 kapa Q355. Galvanizing e chesang e fihlela maemo a ASTM A123, ISO1461 le AS/NZS4680. Ehlile, re boetse re thabetse ho fihlela maemo a mang a boleng le botenya bo fapaneng ba HDG bakeng sa bareki ba rona, kaha ke moetlo oa rona ho arabela kapele litlhoko tsa bareki le ho nka khato hang-hang. Lethathamo la nako e telele la k'hamphani la litlhaloso tse tloaelehileng tsa WF lithane tse 2000, ho fihlela litlhoko tse potlakileng tsa ho tlisa tsa moreki.
Re ananela merero ea bareki ba rona joalo ka ha re ananela lihlahisoa tsa rona. Re sebetsa le bareki ba rona ho tloha qalong ea projeke, litharollo tse betere tsa ho paka le ho kenya thepa; kemiso e tenyetsehang haholoanyane ea ho tlisa thepa le litlhahlobo tsa motho oa boraro kaofela li tla fumana tlhokomelo e tšoanang mona. Esita le ka mor'a hore projeke e phethoe, bareki ba rona ba lefats'e ka bophara ba ntse ba ka itšetleha ka tšebeletso ea rona ea kamora thekiso ho netefatsa hore sehlahisoa se tla sebelisoa ka katleho nakong e telele.
