railroad spikes
Materials and manufacturing process of road spikes
Railway spikes are usually made of high-quality materials such as high-strength steel, alloy steel or stainless steel to ensure that they can maintain good performance in extreme environments. In terms of manufacturing process, the strength and durability of road spikes are effectively improved through forging, heat treatment, surface anti-corrosion and other links. Through hot-dip galvanizing, railway spikes can effectively resist humid and corrosive environments and extend their service life. In addition, some special-purpose road spikes may also use high-performance steel that is fatigue-resistant and crack-resistant to meet the special needs of specific projects for road spikes. High-quality materials and advanced manufacturing processes are the key to ensuring the long-term and stable operation of railway spikes.
