導軌采用熱鍍(du)鋅(xin)、硬軋鋼結(jie)構，S250GD + Z275-M-A-C 板冷成型，材(cai)料符合 DIN EN 10147（材(cai)料規(gui)范）和 DIN EN10143（尺寸(cun)公差(cha) )，鍍(du)鋅(xin)表面處理 (140g/ m2 , 9.8μm 厚度 ) 雙(shuang)面應用，焊縫外熱鍍(du)鋅(xin)。 

注意(yi)：禁止將安全鉗與配重側的(de)導(dao)軌一起使用。 

Guide rails are cold formed from hot galvanized, hard-rolled constructional steel, S250GD+Z275-M-A-C plate. The material follows DIN EN 10147 (material specification) and DIN EN10143 (tolerances on dimension). Zinc coating surface treatment (140 g/m2 , 9.8μm thickness) is applied on both sides. Welding seam is externally hot galvanized. 

NOTE: It is forbidden to use the safety gears with these guide rails on counterweight side.
