1. Argon arc welding is an ancient method of welding steel grating. This welding method has high technical requirements for welders. If the welder is not skilled, it is easy to cause welding slag to remain at the welded joint between the flat steel and the twisted steel of the galvanized steel grating. This is a bumpy situation with customer reactions.
2. Welding is a relatively new welding method for welding galvanized steel grating. The method has high productivity and relatively low labor intensity. The disadvantage is that the cost is relatively expensive, resulting in increased production costs.
3. The most important and popular welding method for galvanized steel grating is machine pressure welding. Machine pressure welding actually adopts double-guaranteed welding technology, which is first compacted and then machine welded. This welding method can completely melt the twisted steel into flat iron, which greatly increases the firmness of the galvanized steel grating. Apply oil to the hot-dip galvanized steel grating to avoid direct contact between air and zinc. It should be noted here that if you want to paint, you must wipe off the oil on the outside of the steel grating. If the hot-dip galvanized steel grating is used for painting, it can be treated with phosphate film. Phosphate will adhere strongly to the hot dipped galvanized steel grating on the outside, forming a loose porous shape which provides excellent footing for the coating and a strong solid adhesion. Store the hot-dip galvanized steel grating in a well-ventilated place, or use a dry machine or a dry stove to avoid condensation in seasons with high humidity and large differences between cold and warm. Be careful not to be soaked and wet by water. If you're soaked in dew or water, you should be bored. You can also unpack and blow dry with a fan. Store in a well-ventilated place. If the temperature difference between cold and warm is large, places prone to condensation should be avoided.
