grating frame

In the practical application of steel gratings, we often encounter many boiler platforms, tower platforms, and equipment platforms laying steel gratings. These steel gratings are often not of standard size, but of various shapes (such as sectors, circles, trapezoids). Collectively called special-shaped steel grating. Special-shaped steel gratings are produced according to the actual needs of customers in various irregular shapes such as circular, trapezoidal, semicircular, and fan-shaped steel gratings. The main processes include corner cutting, hole cutting, arc cutting and other processes, thereby avoiding secondary cutting of the steel grating after arriving at the construction site, making construction and installation faster and simpler, and also avoiding damage to the galvanized layer of the steel grating caused by on-site cutting. shape angles and dimensions When customers purchase special-shaped steel gratings, they must first determine the size of the special-shaped steel gratings and the places where they need to be cut. The shape of the special-shaped steel gratings is not square. It may be polygonal, and there may be additional cuts in the middle. Punch. It is best to provide detailed drawings. If the size and angle of the special-shaped steel grating are deviated, the finished steel grating will not be installed, causing great losses to the customer. Special shaped steel grating price The price of special-shaped steel grating is higher than that of ordinary rectangular steel grating. This is caused by many factors. The main factors are as follows: 1. The production process is complex: ordinary steel gratings can be welded directly from the raw materials, while special-shaped steel gratings need to go through processes such as corner cutting, hole cutting, and arc cutting. 2. High material loss: the cut steel grating cannot be used and is wasted. 3. There is less market demand, fewer applications, and the complex shape is not conducive to mass production. 4. High worker costs: Because the production of special-shaped steel gratings is extremely complex, the production volume is low, and the production time is long, the workers’ wage costs are particularly high. Special-shaped steel grating area 1. If there is no drawing and it is processed according to the user's specified dimensions, the area is the sum of the actual number of steel gratings multiplied by the width and length, which includes openings and cuts. 2. When the user provides drawings, the area is calculated based on the total peripheral dimensions on the drawing, which includes openings and cutouts.
