How to avoid the loosening of zinc steel fence

What measures can prevent the zinc steel fence from loosening? Zinc steel fence, as a kind of fence protection product, is of course not allowed to appear loose. So what measures should we take to avoid this situation?

1. The handrail on the top of the handrail should be fixed to the wall against the wall. Pay attention to the inspection and control of the above four aspects during the construction of the fence. The focus is on the connection between the bottom of the column and the ground. After installation, you can check whether it shakes by hand test. If it does not move, the installation requirements are basically met. 

2. The column and the connecting piece are firmly combined, tightly without gaps, and the overlap length is as long as possible without affecting the appearance quality.

3. According to the principle of three points forming a plane, the expansion bolts of the fixed connecting piece cannot be in the same straight line, and the spacing should be as large as possible to enhance the stability of the connecting piece. For example, when connecting by electric welding, both the inside and outside of the fence must be welded.

4. Installing zinc steel fence connectors shall not be fixed on the floor with wooden bottles, wood screws, or directly with wood screws.

The identification method of zinc steel fence:

1. Check whether there is a broken line on the surface of the zinc steel fence. A very good zinc steel fence has regular textures on the surface. If the surface of the zinc steel fence has various irregular fold lines, it means that the merchant neglects quality in the pursuit of quantity in the process of producing the fence. The lower the amount is too large, and the folding will occur during the next rolling. As a result, the steel strength of the zinc steel fence produced is greatly reduced.

2. Check whether the surface of the zinc steel fence is smooth. Generally, zinc steel fences with a very smooth surface are of good quality, while those with rough surfaces are inferior zinc steel fences, and some are even uneven. The main reason for this inferior fence is that the iron art itself has uneven materials and many impurities, and the manufacturer’s equipment and production processes are not in place, which causes the zinc steel fence to stick to steel and leave scars during the production process.

3. Check the zinc steel fence to see if there are cracks on the surface. Under normal circumstances, iron railings with poor quality can see cracks on the surface. The main reason for this problem is that the raw materials are adobe materials, which are prone to cracks during production.

4. Check the metallic luster on the surface of the zinc steel fence. The surface of the high-quality zinc steel fence has a very strong metallic feeling and bright colors. On the other hand, the surface of poor quality iron fence will appear light red or the color of pig iron. The main reason for this problem is that the steel temperature did not meet the standard during the production process, causing the surface to rust or corrode.

5. Check whether the cross section of the zinc steel fence is flat. Under normal circumstances, we can know the strength of the zinc steel fence manufacturer from its cross section. If the cross section of the zinc steel fence is very flat, it means that the manufacturer of the zinc steel fence pays much attention to the production process of the zinc steel fence. If the cross section of the zinc steel fence is uneven, it means that the manufacturer has not considered the production quality Good off.
