Steel Alloy Railway Track E Clips

Railway Clip is used to fasten the rails to the underlying base plate together with the concrete sleeper. A variety of different types of heavy-duty clips are used to fasten the rails to the underlying baseplate or Sleeper, one common being the E Clip, which is shaped like a stubby paperclip. Another one is the SKL Tension Clamp, which is also the most widely used type all over the world. Others like KPO Clamp and Nabla Clip, also used in different situations.

Surface Treatment and Adaptation Standards of Railway E-Clips

Surface Treatment Process	Corrosion Resistance Performance	Applicable Working Environment	Adapted Railway Standards	Matching Rail Types	Application Advantages
Plain Oiled	Basic corrosion protection	Indoor storage or dry inland railway lines	GB/T 1222, DIN 17221	43kg/m, 50kg/m common rails	Low cost; Convenient for on-site cutting and secondary processing
Oxygen Black	Enhanced wear resistance, moderate corrosion resistance	Ordinary trunk railways with infrequent rain	BS 970, UIC	UIC 54, BS 80 lbs rails	Improves surface hardness; Reduces friction between clip and rail shoulder
Zinc Plated	Good corrosion resistance against humid air	Suburban and urban rail transit lines	AREMA, JIS	Light rail and subway special rails	Extends service life in semi-humid environments; Easy to inspect surface defects
Hot Dip Galvanized	Excellent corrosion resistance against salt and moisture	Coastal railways and marine - climate areas	GOST R - EASC, IS CR	60kg/m, UIC 60 heavy rails	Resists salt - spray corrosion; Maintains performance for over 15 years in coastal areas
Dacro Coating	Superior corrosion and high-temperature resistance	High-speed railways and heavy - load freight lines	VALEC, RDSO	115 RE, BS 100 lbs rails	Prevents corrosion from train exhaust; Withstands high vibration without coating peeling
