Some small-scale black-hearted manufacturers directly omit the pre-treatment process steps of galvanizing, and directly wipe the black tube with a cloth and then galvanize directly. Such profiles are also very easy to rust. Before doing part of the treatment, some manufacturers only do rust removal. This is also an unqualified product. If the pH extracted from the pre-treatment cleaning solution exceeds the standard, the pipe will be more prone to rust. Therefore, the products produced by small manufacturers with substandard technology cannot be used at all, only strong.

　　 Only manufacturers with advanced technology will do the whole process and produce real zinc steel balcony guardrail pipes. Zinc steel was used in highway guardrails in the early days. Zinc easily forms an oxide film with oxygen to prevent further oxidation of the steel, so it will not rust without destroying the zinc layer.

It has not been more than ten years since zinc steel products have been used for civilian use. The balcony guardrails and stair handrails assembled from good zinc steel pipes will not rust for thirty years, will not fade for twenty years, and can withstand wind, sun and rain. The colors are fresh, easy to clean, and self-cleaning. They are quickly widely accepted and welcomed by the masses. Zinc steel manufacturers have also sprung up and established. Driven by interests, the quality of products is now uneven, and the prices are very different. There are many secrets hidden in them.
