Introduction
I. Use of attic flexible staircase
The attic flexible staircase is mainly used in the attics and shops where space is limited to link upstairs and downstairs as a main channel. The main material is high-strength steel. The door plank is made of special insulation board, with electrostatic spraying surface. It's stable, reasonably priced, beautiful and practical, easy to operate and install. It is the best choice to replace the fixed stair and save interior space. 
II. Advantages
1. Occupying small space
Traditional staircase is fixed and occupies certain space. But the new model flexible staircase doesn't occupy any space downstairs and only occupies less than 1m2 upstairs.
2. Good insulation effect 
As a special staircase for the attic, the flexible staircase is installed with the door and the hole well sealed to prevent the indoor draft from the outdoor. Such isolation makes indoor temperature unaffected by the outdoor. 
3. Easy operation 
Due to its technological features and scalable performance, attic staircase is easy to opened and put down. It's very convenient and flexible to operate. 
4. High concealment 
When the flexible staircase is installed, a small cut is made between the attic and the room, which can be blocked by the door plank with the same color as the ceiling. When not used, the staircase is hidden in the attic with the door plank blocking, which helps to make more reasonable use of limited space. 
Wooden staircase with metal components, may be damaged because of collapse, wear, worms, or fungal attack, which can be repaired by professional personnel. But more important is the early stage of the maintenance. Proper maintenance can prolong the service life of the staircase to a great extent. When using steel and wood staircase or wrought iron staircase, we should pay attention to preventing moisture, fire and strike.
