How to determine the quality of hot dip galvanizing produced by the manufacturer?

At the time of purchase of hot dip galvanized products we find some of the products quality good and bad are intermingled, for a new buyer, how to distinguish manufacturers which hot dip galvanized products are good which hot dip galvanized products is bad?

For hot dip galvanized products quality, the most direct method to judge is its thickness, because the larger the thickness of hot dip galvanized anticorrosive, the better, so we can through a simple visual inspection to see whether the quality of hot dip galvanized products meet your requirements.

Hebei Annuo Automation Technology Co,.Ltd is a professional do galvanized equipment, more than 20 years to consistently strive for good galvanization industry reputation enterprise, in plating, hot galvanized, cold galvanized products such as the characteristics and requirements of has a wealth of experience.

Company has passed ISO9001 quality management certification system, in the production system in strict accordance with the requirements of implementation, from the business communication, product design, order placement, processing workshop, molding products, product transportation, every step to customer thought, customer need, well received by the industry.

For hot dip galvanized layer will be affected by the influence of metal material composition, the structure of the organization and change, so the thickness of the galvanized layer can't be exactly the same, if only with simple visual is certainly unscientific, if you want to buy a real good quality hot dip galvanized products, or want to rely on scientific methods of measurement.

Generally speaking, the more adhesion of hot-dip galvanizing, the better the product, so the commonly used measurement methods are film thickness measurement method and pickling method. Film thickness measurement is more convenient than the pickling process, main is to use the measuring of hot dip galvanizing attached induction phenomenon, but it is a prerequisite for the measurement of metal material surface must level off, smooth, not uneven, so that the measured results are more accurate.

Pickling method is the measurement of hot dip galvanized slice, is the most accurate measurement method, generally used in formal inspection. But the disadvantages of many, such as slice of time spent too much time, such as hot dip galvanized volume too large, you cannot use this the pickling process, so I suggest that at the time of measurement with film thickness measurement of whole first, reoccupy pickling process for inspection result, so the result is accurate. Anno is an honest enterprise, we believe you will choose us to be satisfied with our service and products.
