In fact, Jinan iron guardrail is fixed by screws. Do you know what points to pay attention to when selecting anti-theft screws? Next, follow the iron guardrail manufacturers to learn about the following, hoping to help you.

有些廠家為了節省成本使用比較劣質的螺絲來組裝鐵藝護欄，這樣必然會造成很大的安.全隱患啊，而且不同的配件需要針對性的使用不同的螺絲。

In order to save costs, some manufacturers use inferior screws to assemble iron guardrails, which will inevitably cause great safety hazards, and different accessories need to use different screws.

比如現在市面上使用較多的拉伸料的固定座，這個固定座標準的配備的螺絲是不銹鋼的拉鉚螺絲，拉鉚和管壁固定在一起然后螺桿扭進去，這樣安裝很穩固，強度也是經過國家檢測部門檢測過的。

For example, there are many fixed seats with tensile materials on the market. The standard screws of this fixed seat are stainless steel riveting screws, which are fixed together with the pipe wall, and then the screw is screwed in. In this way, the installation is very stable, and the strength has been tested by the national testing department.

而且因為拉鉚把鉆孔的邊都包裹住了，這樣孔邊也不容易生銹，這樣本來是好的組裝方式，但是現在有些鐵藝護欄廠家為了節省成本使用自攻螺絲固定，自攻螺絲千萬不能用在起主要作用力的地方的，為何這樣說呢，因為鋅鋼管子相對都比較薄，自攻螺絲攻進去也只能考那么薄的管壁來支撐力。

Moreover, because the riveting covers the edges of the holes, the edges of the holes are not easy to rust. This was originally a good assembly method, but now some iron guardrail manufacturers use self tapping screws to save costs. The self tapping screws must not be used in the place where the main force is exerted. Why do you say so? Because the zinc steel pipes are relatively thin, The self tapping screw can only test the supporting force of such a thin pipe wall.

自攻螺絲前面小后面大很容易就松動了，松動了很容易脫落，而且自攻螺絲是直接攻入鍍鋅管內會破壞管子的涂層，自攻點很容易生銹。這樣自攻螺絲的強度就更查了，如果收到連續的強作用力，自攻螺絲是承受不了的。

The self tapping screw is small in front and large in back, which is easy to loosen and fall off. Moreover, the self tapping screw directly attacks into the galvanized pipe, which will damage the coating of the pipe, and the self tapping point is easy to rust. In this way, the strength of the self tapping screw is more checked. If a continuous strong force is received, the self tapping screw cannot bear it.

但是因為自攻螺絲本身便宜，而且安裝快捷方便，給很多的投機取巧的人提供了機會。這個是說的拉伸料固定座使用的螺絲，還有一個圍欄用的三包圍固定件，這個固定件是采用不銹鋼的防拆螺絲，穿插鎖。這樣不管強度好，而且防拆防盜。

However, because the self tapping screw itself is cheap and easy to install, it provides opportunities for many opportunistic people. This refers to the screws used for the stretching material fixing seat, as well as a three surrounding fixing part for the fence. This fixing part adopts stainless steel anti disassembly screws and interspersed locks. In this way, no matter the strength is good, but also anti disassembly and anti-theft.

還有別的一些配件其實我個人建議是不管什么配件要么使用防拆螺絲，要么使用拉鉚螺絲。盡量少用自攻螺絲。這樣強度和使用壽命都可以得到保障。

There are other accessories. In fact, my personal suggestion is that no matter what accessories are, either use anti disassembly screws or pull riveting screws. Minimize the use of self tapping screws. In this way, the strength and service life can be guaranteed.

防護欄是保障人生命安.全的，起碼的強度都保障不了的話，那還叫什么護欄，螺絲的選用在整個鋅鋼陽臺護欄的配件中是重要的。

The protective fence is to ensure the safety of life. If the minimum strength can not be guaranteed, it is also called guardrail. The selection of screws is important in the accessories of the whole zinc steel balcony guardrail.
