Properties of Galvanized Steel Pipe Welds

Properties of Galvanized Steel Pipe Welds Galvanizing has been used to protect iron and steel from rusting for over a hundred years in places as diverse as the wire rope used for the suspension cables on the Brooklyn Bridge to gutters on houses. Galvanizing is simply coating of zinc over steel. Like paint, galvanizing protects steel from rusting by forming a barrier between the steel and the environment, but galvanizing goes one giant step further than paint — it also provides electrochemical protection of the steel. Since zinc is electrochemically more reactive than steel, it oxidizes to protect the steel […]

Carbon Steel pipe Bollards – Steel Pipe Security for Building Perimeters

Why choose steel pipe bollards Steel posts are one of the simplest, most cost-effective ways to offer protection for buildings and pedestrians from vehicle collisions, as both a physical and visual barrier. Steel bollards can be installed in any surface, indoors or outdoors, to prevent entry from errant vehicles, secure vulnerable areas, and protect site assets. As the population, especially in urban centers, continues to grow, so too does the number of vehicles on the road. With the increase of drivers and cars in and around cities, the likelihood of accidents and collisions has gone up as well. Properly planned […]
