On the surface, the invisible safety barrier profiles of each manufacturer may appear identical in shape, but there are significant differences in their materials and construction. Only by carefully comparing the materials and construction of invisible safety barrier profiles can one distinguish between superior and inferior products.

First, let’s look at the fixing accessories used to secure steel wires within the guardrail accessories: this is the key to determining the quality of the invisible protective mesh in our guardrail accessories industry. This part is hidden, and customers cannot see it when viewing the sample window. Therefore, when customers view the sample, it is best to ask the manufacturer to provide a piece of material so that they can clearly see the internal structure.

There are mainly two types of guardrail profiles on the market: plastic fixing plates and self-tapping screws. As for the advantages and disadvantages of these two methods, I believe customers have their own judgments.

Next, let’s look at the thickness of the profile: The aluminum alloy fixed material of the guardrail profile serves as a support and anchor for the steel wire, and it must withstand the enormous tensile force of the steel wire. Its thickness determines the strength of the entire invisible protective net, making it an important parameter. A good invisible protective net should have an aluminum alloy profile thickness of over 2mm, and the weight of a single (6-meter-long) profile (excluding fixed accessories) should be over 2.21 kilograms. Guardrail profile companies have found that the market price of aluminum alloy is around 26,000 yuan per ton. Some manufacturers, in order to reduce costs and pursue excessive profits, simply fail to meet the required thickness
