High-rise balcony railing with embedded fixing is the safest, because the embedded installation can be fixed accessories under the cement layer, the pipe is deeply welded on the fixed plate, such a security effect is much better than the simple reinforcement with expansion screws, expansion screws into the ground installation if there is 20-30mm plaster layer, you need to deepen the thickness of the plaster layer, When installing a few words bracket, it should be played above the plaster layer to the structural layer. If the column is used to weld the bottom plate fastener, it is also necessary to do a good job of zinc supplementation at the welding part. Once the zinc layer of the welding part is damaged, the consequences are unimaginable. In addition, pay attention to the installation of guardrail connectors, connectors on the iron railings are fixed with self-tapping screws, etc., guardrail installation should not only pay attention to the anti-theft effect, but more importantly, long-term use and safe use, self-tapping is a threaded fastener, if the thickness of the pipe is thin, the threaded force area will be very small, long-term thread will be loose, the screws may also fall off. There will be a big security risk.

For window railing products such as iron anti-theft Windows and iron shutters, the vertical distance of the vertical bar can not be greater than 9.9cm, iron anti-theft Windows and shutters products need to do a good job of form fixing work, high-rise buildings try not to use T-shaped fixed pieces and other thin guardrail accessories, it is best to use expansion screws directly connected to the pipe on the wall, so it is stronger. When installing into the wall, reinforced concrete soil, red brick and other walls can be directly dug into the wall to install shield railings, if it is a hollow brick wall or casting block need additional processing, such a wall force is too small, expansion screws are easy to loose.
