ASTM A992 W8x28 Litekanyo tsa Sefate sa Tšepe sa Sebopeho se Sephara sa Flange
ASTM W8x28Sefate sa Tšepe sa Libopeho tse Sephara sa Flangeke profil e tloaelehileng e phutholohileng ka ho chesa, e loketseng ts'ebeliso ea mechini le ea kaho. Litekanyo tse ikhethileng Bakeng sa boima bo tloaelehileng ba 28 lb/ft, lehlaseli la W8x28 le sebelisoa haholo mehahong ea khoebo, ea indasteri le ea bolulo.
Lehlakore la sephara la W8x28 le ka fanoa ka mefuta e fapaneng ea tšepe, phekolo ea bokaholimo le bolelele e le hore le ikamahanye le litlhoko tsa sebopeho sa projeke ea hau, ha ka nako e ts'oanang le latela maemo a ASTM a amehang.
