Edge guard is an important link of safety protection, and the quality of products is directly related to the personal safety of constructors. Excellent products have strong protective ability and obvious warning effect. Now let's teach you how to distinguish the quality of products.

咱们要看产品的色彩是否艳丽、饱满。防备大于抢救，警示效果关重要，色彩明显、饱满的防护栏可以被人容易的发觉，从而防止车辆因疏忽撞击防护栏，也能警示施工人员接近施工现场，慎重行事。

We want to see whether the color of the product is gorgeous and full. Prevention is more important than rescue, and the warning effect is very important. The protective fence with obvious and full color can be easily found, so as to prevent vehicles from inadvertently hitting the protective fence, and also warn constructors to approach the construction site and act carefully.

其次咱们要看产品的网片怎样样，一般网片是由不一样规范的镀锌钢管焊接而成，镀锌钢管的强度、尺度和厚度都会直接影响到网片的质量，再就是看焊点和编制方面，一般好的网片每一个焊点都能够很牢固的衔接，不会出现脱落的情况。

Secondly, we should look at the mesh of the product. Generally, the mesh is welded by galvanized steel pipes with different specifications. The strength, scale and thickness of galvanized steel pipes will directly affect the quality of the mesh. Then, in terms of welding joints and preparation, each welding joint of a good mesh can be firmly connected without falling off.

再者需求留意的是基坑临边护栏的表面处理，一般产品焊接完成后都会尽心喷塑处理，在这方面只需需求留意喷塑的整体均匀程度和涂料的好坏。一般好的涂料色彩都比较艳丽，且附着力强，具有更好的防锈防腐蚀才干。

In addition, we need to pay attention to the surface treatment of the guardrail near the edge of the foundation pit. Generally, the products will be sprayed with plastic after welding. In this regard, we only need to pay attention to the overall uniformity of the spraying and the quality of the coating. Generally, good coatings have bright colors, strong adhesion and better anti rust and anti-corrosion ability.

还有就是看产品的分量，产品的尺度、用料薄厚都会使分量发生动摇，产品的分量一般上下差0.5公斤，分量合格说明产品没有偷工减料，防护才干自然也会达到预期。

In addition, it depends on the weight of the product. The size of the product and the thickness of materials will shake the weight. The weight of the product is generally 0.5kg up and down. If the weight is qualified, it means that the product has not cut corners, and the protection ability will naturally meet the expectations.
