Steel grating is a steel product made of flat steel and crossed with cross bars (twisted square steel, square steel, round steel, flat steel, etc.). At a certain distance, welded into a square grid in the middle. Steel grating is mainly used as ditch cover plate, steel platform plate, steel ladder tread plate, etc. The cross bar is generally made of twisted square steel, and the steel grating is generally made of carbon steel, which can prevent oxidation. It can also be made of stainless steel. Steel grille has the properties of ventilation, lighting, heat dissipation, anti-skid, explosion-proof and so on.
It is generally required that the span and load of steel grating must meet the industry standards of steel grating, otherwise it is easy to cause potential safety hazards. To do this, it is not necessary to ensure that the raw material of the steel lattice platform is regular flat steel. The width, thickness and center spacing of the specific steel lattice plate have detailed requirements, and the load and span of the steel lattice plate of different sizes There are strict standards.
Steel grating plays a very special role in many large sewage treatment plants. Through the effective isolation of the steel grid, the sewage can be effectively isolated, which has certain requirements for the isolated steel grid. Sewage treatment platform requirements are very strict. Especially in heavy industry, heavy industry work platforms have strict requirements on load, span, acid and alkali resistance, moisture resistance, sun protection, explosion-proof and so on. And there are strict requirements for installation, otherwise there will be big mistakes. So steel grating is the best choice!
Application of steel grating in platform infrastructure
In the past ten years, steel grating has become an important material for the construction of platform infrastructure in my country. After the steel grating industry was widely used at that time, only a little was known. At present, stainless steel grating will still play an invaluable role in future infrastructure construction. Two meters above sea level, four meters above sea level. Various shaped steels are used as the skeleton, then each platform is adjacent to a small keel, and a huge platform steel grille is laid on the small keel.
The entire suspended floor can be made into a production platform, which can be left or rigidly set up for deployment. The utilization rate of other things and other platform steel gratings is poor, such as allowing to ensure that the platform steel grating will not be dented and deformed.
Steel gratings are also widely used in infrastructure construction of sewage treatment plant platforms. Due to the needs of the sewage treatment plant, it is necessary to use steel gratings. There are two commonly used steel gratings: one is galvanized steel grating. One is a glass and steel grating. In general, steel gratings in sewage treatment plants have good comprehensive economic benefits: the manufacturing cost of glass gratings in sewage treatment plants is 1.4-1.8 times that of steel gratings, and the installation cost is only about 30% of carbon steel. The maintenance cost of the grid is almost zero.
Galvanized steel grating needs to be repaired every year, and the accumulated maintenance cost greatly exceeds the total cost of FRP grating. Although the initial investment cost of FRP grating is slightly higher than that of galvanized steel grating, the total economic benefit is 4 to 5 times that of steel grating. In addition, due to the material title, the FRP grating has a strong anti-hysteresis and a certain elasticity, so that people who have been working on it have a sense of peace. As a platform, it removes the tension in the legs and back of the staff and increases the serenity of things and thus the efficiency of things, which is guaranteed by human engineers.
