After the production of galvanized grating plates and grating plates, rust prevention treatment should be carried out. There are two types: hot-dip galvanizing (hot-dip galvanizing) and electroplating galvanizing (cold galvanizing).
The standard for galvanized grating plate is GB/T 13912-2002 Technical requirements and experimental methods for hot-dip galvanizing of steel parts; Cold galvanizing is not advocated by the country due to its high pollution.
The grating board produced by our factory is also known as steel grating board. It is a type of steel product that uses flat steel arranged in a certain spacing and cross arranged with horizontal bars, and welded into a square grid in the middle. It is mainly used to make gutter cover plates, steel structure platform plates, steel ladder step plates, etc. The horizontal bars are generally made of twisted square steel as a new material and new product, which is increasingly widely used. Its superior performance and good cost performance ratio show its application prospects.
The production methods of grille panels include machine pressure welding and manual production Machine pressure welding uses a high-voltage resistance welding machine, where the robotic arm automatically places the horizontal bar horizontally on a uniformly arranged flat steel. With strong welding power and hydraulic pressure, the horizontal bar is pressed and welded into the flat steel, resulting in high-quality grid plates with strong, stable, and high-strength welding points Handmade grating panels are first punched on flat steel, and then the horizontal bars are spot welded into the holes. There may be gaps between the horizontal bars and the flat steel, and it is impossible to weld every contact point, resulting in weak welding and reduced strength
Galvanized grating can be used in metallurgy, mining, petroleum, power and industrial fields, as well as some civilian fields. As a new type of building material, grating is increasingly being widely used. The so-called new materials have a history of over several decades in foreign countries, but they have only been widely used in China in the past decade. But like aluminum alloy doors and windows, compared to traditional materials, people still habitually refer to them as new materials.
