Trench cover | Steel Grating | Galvanized Steel Grating a test method, test trench cover appearance. If the trench cover is hand-welded, it will generate a lot of welding slag, in order not to affect the appearance, may propose to clean up. If the trench cover is machine welding, quality of wrapping is a major factor affecting the quality of products. Weld regularity, with or without open welding Weld, is the need to look carefully at the eyes. Second, the test trench cover of size, diagonal. The national standard for length and width precision steel grating is 5mm. Each trench cover the length and width were reduced scale 5mm, easy to install. If every piece of steel grating Grand 5mm, it is estimated the site can not be installed, so find a short less than 5mm steel grating normal (consider installation factor), if you do not need a reduced scale, can advance that I am using NC welding accuracy can be controlled within 3mm. The diagonal measurement of the product, if the data is equal to the diagonal measurement error was less than 5mm, then the apparent size of basic products on the basic qualification. Third, test trench cover the pitch and flat steel thickness, trench cover the pitch affects the capacity and trench cover construction costs, we GB in the general identification of the center of the pitch is flat, the correct measurement method From a distance the other flat in the center of the center of the flat, if someone tells you it should be the distance from the flat edge to the other edge of the flat root, that is wrong. The thickness of the flat steel thickness of national standards for the largest flat steel can error + -0.25mm, generally thick HDG will increase the thickness ah, so you have to use calipers card data is not more than 0.25mm product is qualified. Hebei Airlines Golden Screen Products Co., Ltd. in a "people-oriented, quality for survival," the purpose of the strict control of product quality, welcome customers to visit our company, to expand for. Drain cover introduction galvanized hot dip galvanized steel grating trench cover made ditch (well) cover, with a variety of models to choose from to suit different load and span requirements. Widely used in municipal roads, garden facilities, residential quarters, schools, stadium management and other different places. Depending on different occasions, our company can provide different specifications of the ditch (well) cover the surface of hot-dip galvanizing, cold galvanizing (plating), or not treated. Trench cover size selection 1. Drain cover Drain cover galvanized steel direction bearing (support) direction, according to ditch (well) wide gaps remain flat fixed length L; 2. Press the ditch (well) long typesetting Standard plate taken with machining modulus wide 995mm, leaving a gap between the plates 5mm; 3. ditch (well) remaining less than one meter long section modulus given by size; 4. Select the steel according to the ditch (well) wide and load requirements grating model. 5. recommended to choose a standard size design and construction, and other specifications can be customized.
