How much do you know about the protective effect of galvanized angle steel? The thickness of hot-dip galvanized layer of angle steel is generally more than three times of the thickness required in this standard and more than ten times of the visible thickness. High quality hot angle steel has good covering ability, and the actual coating is dense and stable. Its composition does not contain impurities such as inorganic substances. When the angle steel is seriously damaged and even endangers the iron matrix itself, the zinc layer of the angle steel must produce corresponding electrochemical protection to the matrix. The atmospheric corrosion resistance of zinc coating to base metal iron is obviously better than that of zinc coating, which fully reflects the excellent external protection ability of angle steel.
At the same time, how to calculate the unfolding length of angle steel?
Brief introduction: the section of angle steel is asymmetric, so the position of neutral layer is not in the section, but at the root of angle steel.
Advantages of galvanized angle steel:
1. Low treatment cost: the cost of hot-dip galvanizing and rust prevention is lower than that of other paint coatings;
2. More durable: the hot-dip galvanized angle steel has the characteristics of surface luster, uniform zinc layer, no missing plating, no dripping, strong adhesion and strong corrosion resistance. In the suburban environment, the standard hot-dip galvanized antirust thickness can be maintained for more than 50 years without repair; In urban or offshore areas, the standard hot-dip galvanized antirust coating can be maintained for 20 years without repair; Zhengzhou channel steel manufacturer
3. Good reliability: the zinc coating and steel are metallurgically combined and become a part of the steel surface, so the durability of the coating is more reliable
4. Strong toughness of the coating: the zinc coating forms a special metallurgical structure, which can withstand mechanical damage during transportation and use; Zhengzhou channel steel manufacturer
5、 性保護：鍍件的每一部分都能鍍上鋅，即使在凹陷處、尖角及隱藏處都能受到 保護;
5. Sexual protection: every part of the plated part can be plated with zinc, even in the depression, sharp corner and hidden place can be protected;
6. Time saving and labor saving: the galvanizing process is faster than other coating construction methods, and the time required for painting on the site after installation can be avoided.
