You may not notice it, but you use the stairs almost every day. Even if you live in a bungalow (which often times also has stairs for a relatively elevated level of the house), you may encounter (and use) stairs in work, in the mall, in transport system stations, or where it is that you will need a travel vertically.
You might notice that even in this modern world, when a building with one hundred floors can have as many elevators and escalators it needs, stairs are still a necessary or integral part of the main building structure. First, of course is because stairs are really an integral part of the whole structure of a domestic or commercial (high-rise) building, not to mention that it will of course still work (or more approbably, be used) even without electricity. Second, even the elevators and the escalators are working; you may always find the need to use the "waiting-free" traditional stairs, especially if you will just go up or down a level or two. Moreover, especially during these times when programmed exercise regimen is rare opportunity for the busy worker, ascending and descending stairs are a great exercise in itself! And of course, (these is especially true for homes) a grand-looking stair way is always a good point for your house, which is reminiscent of the elegant stairways that you can only see on mansions and palaces. With these functions, it is absolutely necessary that a stairway is beautiful and sturdy. And one sure way to have both beautiful and stable stairway is to make it decorative and sturdy stair parts!
There are many different kinds of stair parts. First, is of course in terms of the materials, there are wooden stair parts, metallic stair parts, marble stair parts, concrete stair parts, stone stair parts, among others. They can also differ from their general shape, design, and color. These differences in stair parts of course account for the differences in stairways themselves. You can construct your stairway by using only one type of material, as in the elegant marble stair ways of large houses or you can use a combination of materials, which is common in modern houses. You can focus also have a combination of designs, although more common is the use of only one design. The important thing is that the final design of your stairway will not just be pleasing in your eyes (and of the others who will see it), but also of course is stable enough to withstand constant use (for obvious safety reasons).
Generally, when choosing the Stair Parts for the intended stairway, the design of the whole house is considered, for it is important that the design of the stair parts (and eventually, the stair way) will complement that of the rest of the house, after all, it is an integral part of it.
