What is the height of the outdoor stair railing? What material is good for outdoor stair railings?

In outdoor public * * * areas, the passenger flow is certainly easier to be larger, especially the left and right stairs. In order to better ensure the safety of life, the railing of stairs also plays a very important role, so the railing height of outdoor stairs must have relevant regulations. So, what is the height of the railing of the outdoor stairs? What material is good for outdoor stair railings? We will explain it for you.

What is the height of the outdoor stair railing?

With regard to the height of stair railings, China has formulated some relevant documents: General Principles for Design of Civil Buildings (JGJ37-87), among which the relevant provisions in the Code for Construction Acceptance are as follows:

1. The height of indoor stair railing should not be less than 0.90m, and the height of outdoor stair railing should not be less than1.05m, counting from the outer edge of stair tread.

2. When the stairwell is wider than 0.20m, the uprights of stair railings should not be greater than 0. 1 1m, which is also to prevent children from falling.

3. The total channel width of stairs should not be lower than the landing and 1.5438+00m.

4. Stairs in residential buildings, kindergartens, primary and secondary schools and special activity places for teenagers and children must adopt structures to avoid climbing by teenagers and children. When vertical members are selected as stairs, the spacing between members should not exceed 0.11m.

5. When the airport height is less than 24m, the height of stair railing should not be less than 1.05m, and when the airport height is more than 24m and 24m (including middle and high-rise buildings), the height of stair railing should not be less than 1. 10m.

What material is good for outdoor stair railings?

1, stainless steel plate stair railing. The touch is particularly good, smooth and moisture-proof, and the guardrail is generally dirty, so just wipe it with a wet cloth. It is also very durable, and most of them have been used for 20 years or more. But the only major drawback is that stainless steel handrails can make people feel cold and feel worse in winter.

2. solid wood staircase railing. Solid wood railings have a long history. Use solid wood railings from the beginning. The use of solid wood railings in home decoration can improve the atmosphere of the house and create a classic advanced visual impact. However, the solid wood balustrade is very easy to corrode when it is used in outdoor standard and water contacts air, and the cost of solid wood staircase balustrade is high, so it is not suitable for large-scale application.

3, zinc steel guardrail stair railing. The zinc-steel guardrail railing is an integrated assembly process, which does not need electric welding, and is simple to manufacture and convenient to assemble; One-way, lateral, transverse and bottom direction are all aluminum alloy castings, and the key surface is electrostatic induction anti-corrosion spraying process, which is colorful and durable; Pipe fittings are hot-dipped galvanized at high temperature, and the surface is sprayed with electrostatic induction anti-corrosion. The rectangular square tube of the column passes through the automatic numerical control mechanical punch, which not only has a particularly fast assembly speed and a short construction period, but also can be assembled together on site. Polyester is a modified material with a service life of more than 50 years, and it is a high-toughness engineering project. Its compressive strength and strength are higher than those of ordinary steel materials, and it can bear the pressure above 183MPA and the tensile force of 2729MPA per square meter, and can withstand the continuous high temperature within 220℃ without wrinkling.
