Gutter grating _ picking the grille across the country (certified) _ grating

 Power grid plate for you to resolve the new section of the new economy section steel grating steel grating with the new section of flat steel production steel grating, not only can improve the flexural capacity, but also substantial cost savings. Thus, the production of shaped flat steel grating of a new trend in recent years there has been international. Now bearing steel grating flat cross-sectional shape, the main use of the thickness T = rectangular cross-section and an intermediate flat 3,5,8mm waist thinner ends of thick flat steel I-section of manufacturing. (See Figure 1) geometry and mechanical properties of l-section flat rectangular cross-section than the flat to be far superior. In the case of flat height H and F equal to the cross-sectional area, the flexural modulus of section of flat steel I-section of Wx = 0.200 ~ 0.203FH, and flexural modulus of section of flat rectangular cross-section of: Wx = 0.167FH galvanized grating, therefore, I-section flat rectangular cross-section than the flat bending resistance is much higher. However, due to the shape of the characteristics and limitations of flat steel I-section, not the T = 3,4,5,6,8ram of all sizes are flat rectangular cross-section with other strong, flat contour of the I-section of the instead. These two series of I-section thickness of flat steel specifications active use also subject to certain restrictions. The main reason is: When a small flat height H, I-section ends of a flat is too small dip galvanized grating, both difficult to hot rolling process is not conducive to the embedded bonding. When the flat height H is large, high waist thick flat steel I-section ratio h / t too big ditch grating, also caused the loss of lateral flat insufficient stability. Therefore grating, steel grating manufacturing currently using a rectangular cross-section galvanized flat steel grating on the main product should be pushed, spray write or paste signs with trademark code into production plant, steel grating model number itself and standard number. Quality certificate: product quality certificate should indicate the standard number of products, steel grade, category, type, size, condition of the surface protective layer, shape inspection and performance check of the results, along with the product delivered to the user as a basis for acceptance . If the user needs, provide quality assurance of raw materials.
