ASTM A709 pereti maitai

Ko te ASTM A709 te Whakatakotoranga Paerewa mo te Structural Steel mo nga Piriti me te whakauru i te waro, te kaha teitei-iti, me nga tira koranu kua tineia me te whakamaarama hei pereti hanganga mo te hanga piriti. Ka tukuna e Gnee nga tohu e rima e whai ake nei o A709; 36, 50, 50W, HPS 50W me HPS 70W. Ko nga tohu huarere e toru o 50W, HPS 50W, me HPS 70W he ASTM G101 kua whakarei ake i te Taurangi Aatete Waihanga Atmospheric ≥6.0.
