coil nails for concrete

Steel wire and iron wire have a lot of similarities, but carefully distinguish, you will find that they are not only different in the material, but also in the product characteristics are very different. So when choosing, make sure you make a clear distinction between the two. Steel wire factory introduces steel wire carbon structure steel made above, generally not galvanized, used for machinery, spring. Black and hard; Iron wire: low carbon steel (mild steel), galvanized, used for joining and wrapping. It’s white and soft.

The lighting surface of each type of shed is designed to be curved, improving the Angle of the light surface, because the lighting surface is curved, no dust accumulation, good light transmittance, high temperature in the shed, after measurement, the average temperature in the shed is 3℃ higher than the traditional bamboo pole cement column shed, the yield is increased by 15~20%, and the harvest date is advanced. The formula is scientific, the surface does not absorb moisture, do not return halogen through modification technology and scientific production process, solve the greenhouse frame rod is easy to absorb moisture return halogen, poor water resistance and easy to change the shortcomings, so that the greenhouse steel pipe in the high temperature and high humidity environment, few drops, frost phenomenon, and reduce pests and diseases.
