How do you shutter stairs?

Estimation of the shuttering area required for construction of the staircase:

  1. Area of rectangle = Length x breadth.
  2. Perimeter of rectangle = 2 (Length x breadth)
  3. Area of square = Length x Length.
  4. The perimeter of square = 4 x Side Length.
  5. Area of Triangle = 1/2 x Base x Height.

What do you use to form round concrete?


  1. Masonite siding has often been an option for forming curves — it’s stiff, yet bendable.
  2. Landscape edging material made out of metal is what some contractors use because it’s easy to find.
  3. “Kerfs” or grooves in two-by-fours allow the wood to bend, or rip thinner plywood to the desired height.

How much room do you need for a curved staircase?

44 inches x 44 inches
If you are going through a hole in the floor your finished floor opening should be two inches greater than your stair’s diameter. For example, if you are using a 3’6” spiral stair to get you access to an attic through a hole in the floor then you would need a finished floor opening of 44 inches x 44 inches.

Where do you put the studs on a stair riser?

The chalk lines on the floor mark the front edge of each riser. Since the riser has to run past the front stud at each stair I move the stud location one inch behind the chalk line to allow for a 3/4 plywood riser and a little room to shim.

What’s the name of the part of the shutter in contact with concrete?

The part of the shutter in contact with the concrete is known as the form lining, while the support timbers are collectively known as ‘bracing’ and consists of horizontal walers and vertical noggins.

What do you call shuttering on concrete slab?
