Stainless steel handrails are an indispensable building in life. Generally, common places such as: residential buildings, office buildings, schools, hospitals, factories and other places where human beings are popular basically have stainless steel handrails. There are two One is to play a protective role, the other is to play a decorative role, and its appearance is a more modern decorative item.
When purchasing materials, it is very important to understand the material of the material. Because of different materials, the corresponding effect will naturally be different. In particular, many families will choose to buy a duplex building, because the corresponding area is relatively larger, and it is very stylish. In order to improve the comfort of living, then the duplex building should be renovated. When decorating, you need to use stair handrails, and the current main escalator handrails are mainly wood and stainless steel. Among the two, many people will choose stainless steel stair handrails, mainly the handrails of this material, which are relatively more convenient for cleaning in daily life. And it has very good corrosion resistance and strong wear resistance, so the service life is relatively longer. When choosing stainless steel stair handrails, you should have an understanding of the price of stainless steel stair handrails. Because the economic level of each head of household will be different, if the corresponding price is clarified, you can choose the appropriate handrail according to your own conditions, and then meet the corresponding needs.
Stainless steel stair handrail construction preparation
After purchasing the stainless steel stair handrails, then construction operations should be carried out. During the construction operation, corresponding preparations should be made. It mainly includes machinery and tools, including cutting machines, portable electric drills, electric welding machines, polishing machines and other corresponding mechanical equipment. At the same time, we should also prepare for the corresponding materials. The main materials are some auxiliary materials, including the use of limestone, the use of putty powder and so on. Of course, you should also have an understanding of the specific quality, and it is very important to understand the price of stainless steel stair handrails when clarifying the quality.
Stainless steel stair handrail construction process
When installing the stainless steel stair handrails, the corresponding preparations have been done, so you should have an understanding of the specific construction process. When installing, the embedded parts should be installed first, and in this step, welding can be used. After that, it is the setting-out process, and when setting-out the line, you should have some understanding of the price of stainless steel stair handrails.
What is the best material for stainless steel railings
To choose stainless steel railings, we first need to know what are the materials of stainless steel railings. Stainless steel railings generally have 201 material and 304 material, and the higher-end ones have 316 material. Of course, we generally use 201 and 304 materials in China, and 316 material stair railings are generally used in foreign developed countries, and the price is relatively high, which is rarely used in China. What is the difference between 201 material stainless steel railings and 304 material railings? We suggest that if the railings are installed indoors, 201 materials can be used, and 304 materials can be used outdoors. Of course, this is not specified, you can choose according to your actual needs, because some engineering projects will specify the material.
So which material has better anti-rust ability? The anti-rust ability of 304 material is higher than that of 201 material, but the price is relatively high.
In addition to being used for balconies, stainless steel railings are also used on stairs, so what kind of specifications should be selected for stainless steel railings for household stairs?
The country has regulations on the height of the stair handrails. Generally, the height from the ground to the finished surface of the stainless steel handrails is controlled at about 900mm to 1000mm. The height of the finished surface of the balcony railing is controlled at about 1050mm to 1100mm. If the stairs or balcony have a water-retaining structure, the custom-made specifications of the railings can be appropriately reduced.

3. The common specifications of stainless steel handrails are 60-60 surface tube, 48-51 column, 36-38 waist tube, and 22-25 flower tube.
Precautions for installation of stainless steel railings
It is also very important to understand the relevant precautions during construction operations. Because the specific precautions are clarified, the construction quality of stainless steel stair handrails can be ensured, and the corresponding construction safety can be ensured at the same time. Of course, it is also very important to understand the price of stainless steel stair handrails.
1. The brightness of the stainless steel railing will be relatively small.
2. The overall rigidity of the handrail is not enough, and there is a trembling feeling when you slap the handrail.
3. The columns are not vertical, the arrangement is not on the same straight line, and the shaking is not firm.
4. The corner of the handrail is not smooth.
5. There is a gap at the connection of the stainless steel railing pipe.
6. The arc of the arc-shaped handrail is not smooth, and there are demolition edges.
7. The pipe wall at the weld is ground through, and the polishing degree is not enough.
8. There are scratches and pits on the surface of the stainless steel railing, which is not so smooth..
9. Glass fixing problem of stainless steel glass railing
Stainless steel railing installation allowable deviation range:
1. Straightness: Among stainless steel railings, the allowable deviation of stainless steel handrail installation is ≤ 4mm. For the deviation of straightness, we can use 10m line and steel ruler to measure.
2. Verticality: In the installation of stainless steel railings, the installation tolerance of the railing columns supporting the entire stainless steel railings is ≤ 3mm. When inspecting the stainless steel railing columns, use a vertical line and a steel ruler to measure, 1 point each along the axis of the bridge and across the bridge.
3. Spacing between railings: As a safety guardrail, stainless steel railings are mainly used to prevent objects from falling from heights. Therefore, the distance between stainless steel railings must be controlled in place. When installing stainless steel railings, the spacing between stainless steel railings is generally ±3mm.
4. The height difference between adjacent railings and handrails. When the stainless steel railing is installed, the height difference of adjacent handrails is different according to the difference between the post and the non-post, and the allowable deviation is also different. With column allowable deviation ≤ 4mm. Without column allowable deviation ≤ 2mm.
5. The plane of the railing is out of position. The plane deviation of the inspection railing can be checked every 30m. The allowable deviation range of misalignment is ≤4mm.
