Cantilevered stair gives a classy and stunning look. These types of stairs are a feat and art of engineering. The beauty of this design is that the weight of the treads is supported just by one wall. The design of the cantilevered stair is not complicated but it something the needs to be done by a specialist. Normally the staircase is the most overlooked areas of a home and this is not right. Staircases are important for the convenience and looks of the home because staircase is the first thing that catches the eye of the people when they walk through the front door. The visual impact of the staircase reproduces the beauty of the entire property. The staircases are something that makes a statement of a property and there are many types of staircases like spiral to spindles and with different materials like glass to granite. As a home owner you need to understand the possibilities of different staircases.
Fact about Cantilevered Stair
Cantilever stair designs are designed in such a way that it is only anchored in the end. The beams carry the load of the support when forced by a moment and shear stress. The cantilevers can be constructed with trusses and slabs as well. It allows the overhanging structures without the external bracing. The stone stair cases in Cantilever designs are there in existence from more than 350 years and before that it was only used in the grad designs. The cantilever stairs are stable and it gets the stability by the nose of each tread resting on the tread under it. It does tip back because of the torsion control from the embedment. There are certain specifications which have to be followed when designing a cantilevered staircase. Experts say that there should be a maximum gap of 125mm between treads and usual flight of 190mm. The prescribed thickness of the treads is 65mm and the structural frame core should be of 400mm steel.
When going for install a cantilever stair, heavy structured wall has to be there at the time of construction and enough space in the plaster line. Tread supports are welded to the steel frame and these are fixed to the wall.
Remember this points
- The main structure should be strong enough to take the load of the cantilever stair because the complete weight is going to be on the wall.
- You have to plan it in advance before the wall is constructed and proper consultation has to be done with the engineer.
- It is always better to approach a reputed staircase provider who has a proven track record of working with the cantilevered stairs.
One cannot take risk and cannot construct without proper consultation. The planning has to be done in the designing phase itself in order to make use of strong and sturdy staircase. This is very important because a standard wall framing is not strong enough to handle the cantilevered stairs.
Follow the Proper Method
If the proper method is followed then cantilevered stairs would look striking, reasonable and protected. It depends a lot on your architect or designer and the staircase builder as it is their job to use the right style to provide you clean lines of flight. In olden times people used to go in for the complete wooden cantilevered stairs but now it is much expensive because of the cost of hardwood. This is the main reason why designers have started to use steel in order to hide the structural designs and by covering the steel by topping with recycled wood. Engineers have started using steel flanges and plates with stiffeners and with single railing with tempered glass which has become popular because of the design and durability.
If the correct method is followed then cantilevered stairs would look striking, reasonable and protected. If you follow above mentioned method then you will surely get your home look classy and stunning.
