Galvanize Railway Dog Spike Sleeper Spikes Doule ear Q235 / 35# 5.6 Grade 

SUYU can supply a range of rail sleeper spikes manufactured to international standards according to BS, ASTM and DIN, among others. SUYU has extensive experience in the rail industry and a high level of expertise in this specialized field. SUYU can manufacture any quantity, big or small, and offers a range of finishes including hot dipped galvanized, black, sherardized or self color for the budget conscious.

Rail sleeper screw spikes are used to fasten sole plates and ribbed base plates to wooden sleepers. direct fastenings of rails on concrete and wooden sleepers. Characteristically, the sleeper screw thread may only be produced in a hotforming operation. The different shapes of the head correspond to the pass form of the respective spanner used for fastening and loosening of the rail sleeper screws.
