Hot-dip galvanized steel grating is now widely used, which fundamentally solves the problem of easy corrosion and damage of traditional metal materials and wood-plastic products. However, the hot-dip galvanized grating should not be exposed to the sun as much as possible, due to the general anti-ultraviolet function.
Long-term exposure to the sun will cause the resin on the surface to decompose, revealing the inner material, which will affect the overall appearance of the product, but will not affect the strength function of the hot-dip galvanized steel grating. It can enhance its UV resistance by making a 0.5mm thick resin-rich layer and UV absorber on the surface of the product during processing.
The surface of a good hot-dip galvanized steel grating is smooth and translucent, and it is relatively smooth to the touch. It is better to have a little bubble, which means that the better material is used, because the density of the good resin is higher, so fewer small bubbles will be generated. It is possible to carry out a load-bearing test on the hot-dip galvanized steel grating to see if it will deform and test its load-bearing capacity.
Hit the hot-dip galvanized steel grating, if the sound is loud, it means that the resin material is more, the filler is less, and the material ratio is appropriate. If the sound of beating is dull, it means that the amount of resin used for the hot-dip galvanized steel grating is less, the calcium powder is more, and the quality of the grating is relatively poor.
