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.

咱們要看產品的色彩是否艷麗、飽滿。防備大于搶救，警示效果關重要，色彩明顯、飽滿的防護欄可以被人容易的發覺，從而防止車輛因疏忽撞擊防護欄，也能警示施工人員接近施工現場，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.

其次咱們要看產品的網片怎樣樣，一般網片是由不一樣規范的鍍鋅鋼管焊接而成，鍍鋅鋼管的強度、尺度和厚度都會直接影響到網片的質量，再就是看焊點和編制方面，一般好的網片每一個焊點都能夠很牢固的銜接，不會出現脫落的情況。

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臨邊護欄的表面處理，一般產品焊接完成后都會盡心噴塑處理，在這方面只需需求留意噴塑的整體均勻程度和涂料的好壞。一般好的涂料色彩都比較艷麗，且附著力強，具有更好的防銹防腐蝕才干。

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.

還有就是看產品的分量，產品的尺度、用料薄厚都會使分量發生動搖，產品的分量一般上下差0.5公斤，分量合格說明產品沒有偷工減料，防護才干自然也會達到預期。

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.
