expanding metal sheets

The strength of the hook net should be satisfactory: when the vehicle is traveling at 80 km/h, the hook net will not fall into the river when it bumps against the railings at a 15 degree Angle. The shape and color of the hook mesh should be in harmony with the surrounding natural environment. The phenomenon planning of important Bridges should be done well.

The formation process of hot dip galvanized layer is the process of forming iron-zinc alloy between the iron matrix and the outside pure zinc layer. The surface of the workpiece forms the iron-zinc alloy layer during the hot dip plating, so that the iron and pure zinc layer is well combined. The process of large roll galvanized wire can be simply described as: when the iron workpiece is immersed in the molten zinc solution, the first zinc and α-iron (body-centered) solid melt is formed on the interface. This is a crystal formed by the matrix metal iron dissolved with zinc atoms in the solid state. The two metal atoms are fused with each other, and the gravitational attraction between the atoms is relatively small.
