The grille, also known as steel grille, steel grid or grille plate, is welded with flat steel and twist steel. The main use of the grille is on the rest platform, walkway, ditch cover and step board.It is also used in terms of environmental protection equipment and sewage treatment. The top crown grille is widely used in petrochemical, electricity, tap water, sewage treatment, port docks, construction modification, shipbuilding, self -rolling parking lots, municipal engineering, sanitation engineering and other fieldsPlatform, walkway, trestle bridge, ditch cover, manhole cover, ladder, fence, etc.

Grid standard
Because its standards are too complicated, I will simply introduce you to the steel grille standard GB700-88 is carbon structural steel, GBL220-92 is a stainless steel stick, GB3159-83 is a hydraulic universal test machine, GB4053.2-83It is a fixed steel diagonal ladder. GB4053.4-83 is a fixed industrial steel platform. GB/T13912-92 represents metal coverage layer, steel products hot -zinc -ray layer technical requirements for steel grid boards need to be loaded and horizontal rods.The latitude and weft is arranged and there is a certain distance to form a grille. The direction of the length is load flat steel, and the width direction is the horizontal rod.At each intersection point of the horizontal rod and the load flat steel, it needs to be fixed at each intersection point, which can be welded, but it is best to use pressure resistance and weld, but can also use arc welding.If the pressure lock method is used to fix the pressure machine, the crossbar can be directly pressed into the load flat steel to achieve a fixed effect.
Steel grille installation
There are two main methods for the installation of the steel grille. One is the welding method used in fixed large contours, and the second is to connect the installation clip between the grille.The welding method is mainly suitable for welding on each corner of the grille that does not need to be replaced for a long time.There are more places for installation and installation, which are mainly suitable for various steel grille single boards to connect into the whole plate.Although this method is simple, there are many requirements. At least 4 sets of installation clamps on each steel grille are installation clips. If the area of ??a single steel grille is large, it needs to be fixed.From time to time, a few sets of installation clips are installed on the fixed support that can be used.
