The steel grating acts as a load bearing for the flat steel, and the twisted square steel has the greatest function of fixing the flat steel without side inclination. We have seen many cases of failure due to wrong orientation of bearings on steel grating products. The following brief analysis how to determine the bearing direction:
1. The direction of the general flat steel on the steel structure is perpendicular to the direction of the steel beams on both sides. Loaded flat bars on both sides of the steel beam will have the best load carrying capacity. If the direction is opposite, the bearing capacity will be the edge sealing flat steel and twisted square steel of the steel grating. The rest of the flat steel will no longer play a bearing role, which will lose the significance of steel grating platform construction. If you plan to build a support in the middle of the steel beam to carry the steel grating, you can ignore the load-bearing direction of the steel grating, but this will undoubtedly increase the construction cost.
2. The direction of the flat steel grating for the trench should also be perpendicular to the support direction of the platforms on both sides of the trench, otherwise the bearing effect will not be achieved. For drainage manhole covers, the general flat steel direction should be perpendicular to the short support direction of the manhole cover. With the large-scale application of steel grating, grid plates of different materials have appeared on the market, so the properties of steel gratings of different materials are also different. Flat steel grating: This is the most common type of steel grating in our life, and it is also the basic type of steel grating with the widest range of applications. It is very scalable. It can be fitted with baffles around the perimeter, square tubes and angles can be used for edging, it can be easily moved with pretend handles and hinges, and additional grating panels can be fitted to create a safe working environment. Composite steel grating is another kind of steel grating composed of steel plates welded on other sealing surfaces on the basis of plane type. Usually, this kind of steel grating is used in places that require a sealing surface and have certain requirements for impact resistance, bearing capacity and structural weight. This kind of grille has almost no difference in flatness except that it cannot leak objects. Ceiling-type steel grating: The ceiling type is mainly used for interior decoration ceiling products. It uses lighter aluminum alloy and steel structure to further reduce the weight without affecting the load-bearing, so that it inherits the high strength, high load-bearing and strong structure of ordinary steel grating, and it is stronger than ordinary steel grating many. The structure is light and handy, which is more conducive to hoisting, and the function is more regular and beautiful.
