Galvanized angle steel is divided into hot-galvanized angle steel and cold-galvanized angle steel. Hot-dip galvanized angle steel is also called hot-dip galvanized angle steel or hot-dip galvanized angle steel. Cold galvanized coatings are mainly based on electrochemical principles to ensure that zinc powder is in full contact with the steel, and the electrode potential difference is generated to prevent corrosion. So what issues should be paid attention to when buying galvanized angle steel? Today, the editor of Yanxin Senyu will tell you something!
1. Price. The price of galvanized angle steel is the most sensitive issue. Consumers want to buy cheap and good quality galvanized angle steel, but the saying "one point, one price" is applicable to hot-dip galvanized angle steel. Sometimes we will see hot-dip galvanized angle steel at the "cabbage price" in the market. At this time, we can't be small and cheap. This "cabbage price" galvanized angle steel we must be vigilant, maybe there will be fussy. It is the hot-dip galvanized angle steel without material. The raw material angle steel is a "black material". The raw materials of the angle steel are made without guaranteeing the material, and then the hot-dip galvanizing process is performed. This hot-dip galvanized angle steel can not be drilled or deformed easily during construction, and some businesses will use cold-galvanized angle steel as hot-dip galvanized angle steel, and cold-galvanized angle steel galvanized Compared with the hot-dip galvanized angle steel, the thickness of the zinc layer is thinner than the hot-dip galvanized steel, the price is cheaper, and the corrosion resistance is shorter than the hot-dip galvanized steel.
2. Zinc layer. The zinc layer thickness specified by the country for hot-dip galvanized angle steel. There are national and non-standard points in the market, and the national standard price is more expensive than the non-standard price. Some bad businesses use non-standard Nanning galvanized angle steel to pretend to be national standard hot-dip galvanized angle steel. When we buy, it is best to use a zinc tester to measure the zinc layer thickness.
3. Calculation method. The calculation method of galvanized angle steel is basically calculation by calculation, weighing, and cost. There are many theoretical calculation formulas. The difference between the minus hot-dip galvanized angle steel is also different. The ton price obtained is slightly different from the actual price. The ton price calculated by the weight calculation and support price is the most real. If you purchase hot-dip galvanized angle steel, It is advisable to use over-pounds for large quantities.
