Stair treads, also called fixed steel grating welding and installation of two ways. Without dismantling of permanent, can be welded, welded on its supports. Specific location on each corner of the plate first root flat Dongtai stepping board manufacturers, welding length of not less than 20 mm treads, not high less than 3 mm fillet welds. has the advantage of using the mounting clip without damaging the zinc layer and removal easy, you can also punch in the side panel with screws. Factory direct cooperation and win-win Jiangyin stepping board manufacturers, the gentleman love of money to road, a cooperative permanent friends, the factory will cherish every opportunity to cooperate Zhenjiang stepping board manufacturers, ?? do not understand value, guarding Jinshan will not be happy.
