What kind of screw should be used for the wrought iron fence is very important, because the whole iron fence is fixed by this screw. And this should take into account the strength and service life of the entire guardrail. Once there is a problem with the screw, it must be fatal to the entire assembled railing. In the past ten years since the appearance of wrought iron fences, different manufacturers have introduced many assembly accessories, and the screws used in each accessory are also various.
In order to save costs, some manufacturers use inferior screws to assemble wrought iron fence, which will inevitably cause great safety hazards. And different accessories need to use different screws targeted.
For example, the fixing seat of stretch material is more commonly used on the market. The standard screw of this fixing seat is stainless steel rivet screw. The rivet is fixed to the pipe wall and the screw is twisted in, so that the installation is very stable. And because the edge of the hole is covered by the riveting, the edge of the hole is not easy to rust. This is a good assembly method, but now some manufacturers use self-tapping screws to fix them in order to save costs. Why do you say that when it is used where the main force is exerted, because zinc steel pipes are relatively thin, and self-tapping screws can only test the thin pipe wall to support the force.
The small front of the self-tapping screw and the large back are easy to loosen, and it is easy to fall off if it is loose, and the self-tapping screw is directly tapped into the galvanized pipe to destroy the coating of the pipe, and the self-tapping point is easy to rust. In this way, the strength of the self-tapping screw can be checked even more. If a continuous strong force is received, the self-tapping screw cannot withstand it. However, because self-tapping screws are cheap and quick and easy to install, they provide opportunities for many opportunists. This refers to the screws used for the stretch material fixing seat, and there is also a three-enclosed fixing piece for the fence. This fixing piece is made of stainless steel tamper-proof screws and intersecting locks. In this way, the strength is good, and it is anti-dismantling and anti-theft.
There are other accessories. In fact, I personally recommend that no matter what accessories you use, either tamper-proof screws or rivet screws are used. Minimize the use of self-tapping screws. In this way, the strength and service life can be guaranteed. The protective fence is to ensure the safety of human life. If the minimum strength cannot be guaranteed, what kind of fence is it called? The selection of screws is important in the accessories of the entire zinc steel balcony fence.
