1. The first is the quality of the iron gate. The internal flower Du is welded by different specifications of wire rod (thin flat material, thin square tube). The diameter and strength of wire rod directly affect the quality of iron flower parts. In terms of selection, we should choose the high-quality finished iron gate produced by regular manufacturers; the second is the welding and forging process of iron gate for several years.
2. The second is to choose the formal Enterprise's iron gate, which is usually made of forged steel. The quality of the interior flower parts and frame of the iron gate is much stronger than that of the ordinary steel pipe guardrail. Moreover, the forged steel and iron fence looks very hierarchical and three-dimensional, showing dignity.
3. Finally, the overall painting process of the iron gate, generally speaking, should pay attention to the uniformity of the paint, and the quality of the paint is also very important.
The iron gate should be installed in the place where the ventilation Du of Bai is relatively high. The metal will be rusted and the chromium plating will take off the film. The acid and alkali with Dao corrosion effect on the iron gate is the "number one killer" of the iron gate. If acid (such as sulfuric acid, vinegar) and alkali (such as methyl alkali, soapy water and soda water) are accidentally stained on the iron gate, the dirty place should be washed out immediately with clean water, and then dried with dry cotton cloth.
