Galvanized platform grating can prevent oxidation and improve its service life. The hot-dip galvanized platform grid plate has strong corrosion resistance between PH6-PH12, and its service life has a great relationship with the external environment. In a dry environment, its service life can reach 70-80 years, and it is generally 20-30 years in industry. The age of cold galvanizing is relatively short, and rust begins to appear in 2 or 3 years. Not galvanized, not only the appearance is rough and unsightly, but also the product can be painted, and the surface is not treated intensively. Hot dip galvanized treads make cold galvanized trench cover up to 3 years. Painted platform grille 5-7 years. The surface of non-galvanized products is easy to blacken and rust, while the surface of galvanized products is very shiny, with a relatively long service life and beautiful and durable appearance. The steel grating is actually a galvanized platform grating.
Why should the surface of the platform grating be galvanized? The original galvanizing is equivalent to prolonging the time of the steel grating so that it can be used for decades. Since the surface of non-galvanized steel grating is easy to rust, rust will reduce its service life, so galvanizing the surface of platform grating not only improves the aesthetics, but also prolongs its service life, which can be said to kill two birds with one stone. There are more than 200 specifications and varieties of stainless steel grating plane type, tooth type and I type. According to different use environments, the surface can be treated with different protection. It has light weight, high strength, large bearing capacity, economical material saving, Ventilation and light transmission, modern style, beautiful appearance, non-slip safety, easy to clean, easy to install, durable and so on. If the flat steel is in an arc (interpretation: it is an elegant line) curved (curved) state, when welding, the flat steel is not straightened, but the flat steel is directly placed on the mold for welding, and the surface looks straight. In fact, the steel grating has been deformed. During transportation, it should be placed stably so that the force is even. It is not easy to be hit hard during loading and unloading. It should be lifted and released gently.
The key to the long service life (life) of the steel grating is whether it is stored carefully and the spot welding of the steel grating is maintained wholeheartedly. Generally speaking, it is divided into two categories: double-sided spot welding and single-sided spot welding. Stainless steel grating is a steel grating made of stainless steel. Its production process is similar to that of ordinary steel grating, except that it does not require anti-corrosion treatment such as painting or hot-dip galvanizing, but requires surface polishing to remove welding slag or scars left during the welding process. During double-sided spot welding, electrodes (electrodes) are fed into the weld from both sides of the workpiece. During one-sided spot welding, the electrode (electrode) is fed from the same lateral welding position of the workpiece. The typical single-sided spot welding method is to use electrodes with large diameter and large contact surface to form welding spots to reduce the current (electron flow) density (unit: g/cm3 or kg/m3). For single-sided two-point spot welding without shunt, the welding current flows through the welding area at this time. In the production (production) of a large number of steel gratings, single-sided multi-point spot welding has been widely used (widely). At this time, it can be powered by 1 transformer (variable air pressure) device, and the type in which each pair of electrodes presses the workpiece in turn can also be powered by a separate transformer (transformer). The latter type, in which all electrodes press the workpiece together, has more advantages. Its advantages are: each transformer can be settled closest to the connected electrode, and its power (referring to the amount of work done by an object per unit time) and scale can be significantly reduced; the process parameters (parameters) of each solder joint can be adjusted independently ;All welding points can be welded together, the productivity (productivity) is high; all electrodes press the workpiece together to reduce the deformation of the steel grating. Multiple transformers are energized together to ensure three-phase load balance.
