ʻO ka HDG maʻamau e pili ana i ka galvanizing wela. ʻO ka galvanizing wela ka hana ʻana i ka metala i hoʻoheheʻe ʻia me ka matrix hao e hana ai i kahi papa hoʻohui, i hui ʻia ka matrix a me ka uhi. ʻO ka galvanizing wela ka hoʻomaʻemaʻe ʻana i nā ʻāpana hao a me nā ʻāpana kila, i mea e wehe ai i ka oxide hao ma luna o ka ʻili o ka hao a me nā ʻāpana kila, ma hope o ka pickling, hoʻomaʻemaʻe ʻia i loko o ka pahu o ka ammonium chloride a i ʻole ka zinc chloride aqueous solution a i ʻole kahi. i hui pū ʻia ka wai o ka ammonium chloride a me ka zinc chloride, a laila hoʻouna ʻia i ka pahu hoʻoheheʻe wela. Loaʻa i ka Hot-dip galvanizing nā mea maikaʻi o ka uhi ʻana i ka lole, ka hoʻopili ikaika a me ke ola lawelawe lōʻihi.
Hoʻohana mau ʻia ke poʻo countersunk o nā bolts galvanized hot dip ma kahi e pono ai ka pilina. He ʻāpana maʻamau ʻole ia i ke ʻano o ka U a no laila ua ʻike ʻia ʻo ia he U-bolt. Hiki ke hoʻohana ʻia nā bolts galvanized hot-dip me nā kaula ma nā ʻaoʻao ʻelua me ka hui pū me nā nati. Hoʻohana nui ʻia ke kumu hoʻohālike no ka hoʻoponopono ʻana i nā mea tubular a i ʻole flaky.
Hoʻoholo nui ʻia ke kūpaʻa corrosion e ka mānoanoa o ka papa galvanized, no laila ʻo ke ana mānoanoa ke kumu nui no ka hoʻoholo ʻana i ka maikaʻi o ka papa galvanized. ʻO ke kihi a me ka wikiwiki o ka hoʻonā ʻana he hopena nui. No laila, ʻaʻole hiki ke loaʻa ka mānoanoa o ka uhi ʻokoʻa.
