1) Grade 316 stainless steel ?this is the stuff to use in most places but is more expensive. These will be HK$ 15 each. (Eight HK to the Dollar.)
2) Grade 304 stainless steel ?these won’t be quite as durable as the 316 hangers. They shouldn’t be used on sea cliffs but will still give good service, especially for short term stuff like adventure racing. These will be HK$ 5 each. The main reason for getting these manufactured is to provide a cheap supply of stainless steel bolt hangers in Yangshuo to try to prevent GMS being used.
你回去研究一下是不是要给基金会买?他们从德国进,没有邮费,就是不知道这次赶不赶的上,反正以后他们还会通知我 |
