Prodcut Advantages of Fire Fighting Steel Pipe
1. Fire Fighting Steel Pipe has strong flame retardant ability. Under the combustion test of alcohol blowtorch, the coating has no spontaneous combustion and does not fall off.
2. Good mechanical properties and high strength of fire fighting steel tubes.It has strong bearing capacity, impact resistance and bending resistance.
