The attic staircase design not only plays a role in connecting up and down, but also forms a visual focus that affects the overall home improvement effect. And a good staircase can often highlight the owner's personality and light up home life. What about loft stairs? Now let's take a look at the loft stairway along with Xiaobian, how to choose the home loft stairway, and design the loft stairway for your reference.
Home loft stair design
In the design of the attic stairs, it is also necessary to pay attention to the suitability of the railing spacing, especially for those who have children at home must pay attention to this design. It should be noted that the distance between the centers of the two railings should be 8 cm and not more than 12.5 cm so as to prevent children from sticking their heads out of the gap and causing dangerous accidents. Railings such as the one shown in the figure are very suitable. If there is a balcony design like the one in the figure, one should pay more attention to the distance between the railings.
First, determine the slope of the attic stairs
Consideration should be given to walking comfort, climbing efficiency and spatial status factors. The line at each step of the bench at each step is called the slope line. The angle between the slope line and the horizontal plane should be the gradient of the stairs (the tangent of this angle is called the gradient of the stairs). The slope of the indoor loft stairway is generally 20 degrees to 45 degrees, and the best slope is about 30 degrees. Stairs for special functions require different slopes. For example, the slope of the ladder is above 60 degrees, the design of the dedicated attic stairs is generally 45 degrees -60 degrees, the slope of the indoor and outdoor steps is 14 degrees -27 degrees, and the gradient of the slope is usually below 15 degrees. Generally speaking, in places with large crowds, high safety standards, or ample areas, the slope should be gentle. For an auxiliary staircase that is only used by a few people or is not frequently used, the slope can be steeper, but it is better not to exceed 38. degree.
Second, the size of the stairs is determined
In the design of a loft stair, the size of the step should generally be adapted to the pace of the person's foot size, and also related to the use of the function in a different type of building. Step size includes height and width. The ratio of step height to width is the gradient of the attic stairs. Stepping under the same slope can have different values ​​and give a proper range to make people feel comfortable when walking. Practice has shown that walking in a comfortable step is generally smaller in height and wider in width. Therefore, when choosing the aspect ratio, it is better to use two kinds of attic stairs of the same slope with a smaller height, because it is more labor-saving to walk than when the height and width are large. However, it should be noted that the width should not be too small, preferably not less than 240mm. This will ensure that the focus of the foot will fall close to the center of the foot and 90% of the heel strike force will be on the way.
Third, determine the width of the ladder
The width of the attic stairwell is generally determined by the flow of people to ensure smooth traffic. Single-pass ladder width should generally be 800-900mm, the general finished loft stairs should be designed according to this width; but stairs for public places, such as: double-pass ladder width should generally be 1100mm--1400mm; The general ladder width should be 1650-2100. If more people circulate, increase the width by 550 (0-150) mm per person. When the width of the bench is greater than 1400mm, the handrails should be set against the wall. When the flow of stairs exceeds 4-5 persons, the middle handrails should be added.

Razor wire, also known as barbed tape, is a type of security fencing wire constructed with sharp edges or points arranged at intervals along the strands. It is designed to prevent passage by humans and is often used to secure military sites, prisons, government agencies, and other high-security areas.
Razor wire for prison is specifically designed to prevent escape attempts. It is often used to top walls and fences around the perimeter of a prison facility. This type of razor wire is usually made of high-tensile wire, which is stronger and more resistant to cutting and tampering.
High tensile razor wire is a type of razor wire that is made from high-strength steel. This makes it incredibly tough and difficult to cut through, even with heavy-duty tools. It provides an added level of security and is often used in high-risk areas.
Galvanized concertina wire is a type of razor wire that is coated with a layer of zinc to prevent rust and corrosion. This makes it more durable and long-lasting, especially in outdoor environments. The term "concertina" refers to the coiled, accordion-like shape of the wire, which can be expanded or contracted as needed. This makes it easy to install and transport, while still providing a high level of security.
