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.

有些厂家为了节省成本使用比较劣质的螺丝来组装铁艺护栏，这样必然会造成很大的安.全隐患啊，而且不同的配件需要针对性的使用不同的螺丝。

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.

比如现在市面上使用较多的拉伸料的固定座，这个固定座标准的配备的螺丝是不锈钢的拉铆螺丝，拉铆和管壁固定在一起然后螺杆扭进去，这样安装很稳固，强度也是经过国家检测部门检测过的。

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.

而且因为拉铆把钻孔的边都包裹住了，这样孔边也不容易生锈，这样本来是好的组装方式，但是现在有些铁艺护栏厂家为了节省成本使用自攻螺丝固定，自攻螺丝千万不能用在起主要作用力的地方的，为何这样说呢，因为锌钢管子相对都比较薄，自攻螺丝攻进去也只能考那么薄的管壁来支撑力。

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.

自攻螺丝前面小后面大很容易就松动了，松动了很容易脱落，而且自攻螺丝是直接攻入镀锌管内会破坏管子的涂层，自攻点很容易生锈。这样自攻螺丝的强度就更查了，如果收到连续的强作用力，自攻螺丝是承受不了的。

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.

但是因为自攻螺丝本身便宜，而且安装快捷方便，给很多的投机取巧的人提供了机会。这个是说的拉伸料固定座使用的螺丝，还有一个围栏用的三包围固定件，这个固定件是采用不锈钢的防拆螺丝，穿插锁。这样不管强度好，而且防拆防盗。

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.

还有别的一些配件其实我个人建议是不管什么配件要么使用防拆螺丝，要么使用拉铆螺丝。尽量少用自攻螺丝。这样强度和使用寿命都可以得到保障。

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.

防护栏是保障人生命安.全的，起码的强度都保障不了的话，那还叫什么护栏，螺丝的选用在整个锌钢阳台护栏的配件中是重要的。

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.
