Construction Large diameter High Strength Hot Rolled Spiral Round
Carbon Welded Steel Pipes Product Advantages
01.Anticorrosive:17 years in heavy industrial areas.
02.Cheap:The cost of hot-dip galvanizing is lower than that of
other coatings.
03.Reliable:The zinc coating is metallurgically bonded to the steel
and forms part of the steel surface,so the coating is more durable.
04.Strong toughness:The galvanized layer forms a special
metallurgical structure that can withstand mechanical damage during
transportation and use.
05.Comprehensive protection:Every part of the plated piece can be
galvanized,and is fully protected even in depressions,sharp
corners,and hidden places.
06.Save time and energy:Galvanizing process is faster than other
coating methods. | Commodity | EN 10219 ASTM A500 Welded ERW Steel Pipe | | Outer diameter | ERW / HFW | LSAW / DSAW | SSAW / HSAW | RHS | SHS | | | 1/8 - 20 inch
