4 inch concrete nails

Hexagonal net structure can be used for slope support, excavation, rock face net mine support form, slope vegetation (green color), railway road isolation block, it can be made into a cage, cushion, used for rivers, flood dam and seawall erosion protection and storage reservoir, river closed cage. Driving and guiding rivers, river flood disaster is a major water and river erosion of destruction, resulting in flooding, resulting in a great deal of loss of property by the amount of soil and water dissipation. Because of this, in dealing with these problems, the application of the habitat grid structure becomes a solution plan, which has the potential to protect the bank forever.

The difference is that hot dip galvanizing is dipped in zinc solution melted by heating, which has fast production speed and thick but uneven coating. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.

Black iron wire application in the process, the main is through the hot metal billet rolling into six point five mm wire rod, and then put it in the drawing into a line of different diameter, the plant and then gradually narrow drawing plate aperture, cooling and annealing, plating process, such as making a variety of different specifications of the wire, the wire compared with ordinary black iron wire, will be more softer, Softness is also very uniform, color is also consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding coat hanger, reprocessing industry and so on.
