Work access and access to hot dip zinc galvanized steel grilles should be designed to prevent pedestrian tripping hazards. To prevent tripping hazards for pedestrians, the hot-dip steel grating should be flat, and the height difference between adjacent hot-dip steel grating, hot-dip steel grating and members should not exceed 4mm. Secondly, hot dip zinc steel grating should be firm equipment to prevent falling. Therefore, hot dip zinc steel grating equipment only needs to use welding method can be firm. The hot-dip zinc steel grilles that need to be moved and installed must be secured using the equipment clamp shared by the hot-dip zinc steel grilles. The number and method of equipment must be added to prevent members from shifting again, and the load must meet the requirements of the work.
Because of the existence of steel grating plate flat steel spacing, can not stop the spark generated when hot work. From the current use of steel grid plate, the gap between the flat steel is greater than 15mm, if the gap is 15mm, may make the nut below M24, M8 below the bolt, 15 below the round steel and electrode fall, including wrench; If the clearance is 36mm, it may cause the nut below M48, the bolt below M20, the round steel below 36 and the welding rod to fall, including the wrench. Small objects fall, may smash the person below, causing personal injury; The instrument, cable, instrument line, plastic pipe, glass level gauge and mirror in the device are damaged, resulting in accidents caused by interlocking of the production device and material leakage. Due to the spacing of steel grating panels, the rain cannot be blocked, and the material leakage from the upper layer directly drops to the first floor, increasing the damage to the personnel below.
Although steel grille plate than traditional decorative pattern plate has the advantages of economic, security, and many other high cost performance, should try to choose the appropriate model selection of the design of steel grating plate model, but in practical application, steel grid plate can be used mixed with decorative pattern plate, in order to satisfy the requirement more reasonable structure, production needs and made more obvious economic benefits.
