How do you shutter stairs?

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

1. Area of rectangle = Length x breadth.

5. Area of Triangle = 1/2 x Base x Height.

What do you use to form round concrete?

Share:

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.

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?
