Below is a list of commonly used steel shutter materials-
- Column/beam side
- Beam bottom
- Steel Props
- Cross bar
- Base plate
- Joint pin
- Turn bolt
- Shutter grill
- Steel Beam
- Shutter clip
- Plain sheet
A short description of each material is given below:
Beam/Column side: This is the part of main form work of beam or column. It is made by combining 16-18 SWG sheet, MS flat bar and MS angle frame with necessary holes for fixing nut-bold/shutter clip in required shape.
Beam bottom: The procedure of making beam bottom is same as beam side.
Steel Props: it is vertical supporting tool used under beam. It also can be used as column strut.
Scaffolding: Scaffolding is the vertical supporting tool of slab form work. The height and width of it can vary as required. Commonly used sizes are 4′-0″ x 4′-0″ and 4′-0″ x 5′-8″.
Cross bar: cross bar is used to support scaffolding horizontally. The size of cross bar depend on the size of scaffolding.
Base plate: Base plate is used to support scaffolding by providing firm platform. It
is the most bottom part of slab supporting.
U-head: This is also a vertical supporting tool used above scaffolding to support runner.
Joint pin: Joint pin is used to joint scaffolding one above another to get the desired slab height.
Turn bolt: Turn bolt is used to pull up concrete form work.
Runner: Runner is a horizontal supporting tool. Normally different sizes of mild steel hollow box used as runner. Commonly used sizes are 4″ x 4″, 4″ x 3″, 3″ x 3″ and 1.5″ x 1.5″.
Shutter grill: Shutter grill is used below plain sheet. It is made by welding MS flat bar. Common size of shutter grill 2.5 x 2.5 feet.
Steel Beam: Temporary horizontal supporting tool used under shutter grill.
Shutter clip: shutter clip is used to fix two beam/column side.
Plain sheet: this is also horizontal supporting tool used above runner or shutter grill
for making slab form work. 16/18 SWG MS plain sheet is used for this purpose. Common size of plain sheet is 3’ x 6’ and 4’ x 8’.
Keep in mind that, there are various type and shape of same material available in the market. Here I am showing only common type steel shutter material available in construction industry.
