First, we have to look at the fence mesh is how, usually mesh is welded by different specifications of wire, wire diameter and strength directly affect the quality of the mesh, in the wire selection should be selected by the regular manufacturers of high-quality wire rod pulled out of the finished wire; The second is the welding or preparation process of the mesh, which mainly depends on the skilled technology and operation ability between the technical personnel and the good production machinery, usually the good mesh is that every welding or preparation point can be well connected. Some of the regular guardrail production factories in Anping are produced by fully automatic welding machines, while a small factory uses manual welding, usually the quality is difficult to maintain.

The second thing to pay attention to is that: the choice of the frame of the guardrail net, some regular manufacturers are using Angle steel and round steel, but the Angle steel and round steel selected in different parts should also be different.

Third, the overall control of the spraying process of the guardrail, generally speaking, the overall product should pay attention to the uniformity of the spraying, and the quality of the paint is also crucial.

The above is a summary of the experience of Qingdao iron processing three points, is the basic conditions for the selection of high-quality fence products, according to the above method, for the purchase of high-quality products we basically have a bottom in the heart, in the future I will introduce you to Qingdao iron fence installation related knowledge.
