ʻO Corten Steel

AHL CORTENe hana ana i ka pepa, coil, tube a me ka pauku i na mea kila i ka EN, JIS a me ASTM. Hiki mai ke kila Ahl-corten i nā ʻano nui like ʻole a ʻo ia ka koho maikaʻi loa no ka ʻimi ʻana i nā ʻano hou a me ka rustic.

Eia kekahi mau māka maʻamau o ka pā kila, a ʻike ʻia kekahi no ko lākou kūpaʻa ʻana i ka corrosion kiʻekiʻe a me ka hiʻohiʻona maikaʻi ma hope o ka pala. E like me TB 1979 ma 09CUPcrni-a.

Nā lawelawe: ka hoʻomaʻamaʻa mua ʻana, ka kulou, ka ʻoki ʻana, ka wili, ke kaomi ʻana, ka kuʻi ʻana, ka hoʻolālā ma ke koi.
