At present, there are many guardrail products on the zinc steel fence market. For example, zinc rod railings, zinc rod balconies, zinc steel stair railings, and zinc steel louvers have similar appearances, which makes many people outside the industry unable to distinguish the quality, especially the material. It is to let most laymen do not understand.
The zinc steel guardrail is intuitively interpreted as an assembled railing product made of hot-dip galvanized steel by punching, pre-treatment and electrostatic spraying. Its main feature is the use of hot-dip galvanized steel pipe material.
The standard zinc steel guardrail is made of Q235 hot-dip steel with a zinc layer of 80g/m2. However, there are many small manufacturers on the market that use low-quality steel with a zinc content of only 30g in order to achieve low quality and low price. Cold-plated steel is also used as a counterfeit; even some factories use ordinary cold-rolled black tubes; it seriously damages the interests of consumers and damages the reputation of the entire zinc steel industry.

If necessary, they should go to the manufacturer to inspect their craft, scale, quality management, etc., and cooperate with the manufacturers of regular and trustworthy. In this way, you can buy a good product with quality and price.
