Starter Bar Placement Calculator - Concrete Block Vertical Steel Reinforcing

This calculator creates a map of starter bar placements for block walls.

Enter walls as panels and openings, in multiples of 200, separated by spaces. eg: a wall with a panel of 2000, then an opening of 1200, then a panel of 6000 is entered as 2000 1200 6000.

Enter all panels and openings (ending in a panel), select Max Centres from the dropdown and hit 'Calculate' to display the starter placement map and diagram of the wall.

You can enter multiple walls, separated by a - (minus sign) or enter and print walls separately.

DON'T BREATH THE DUST If you're cutting blocks, concrete, stone or ANYTHING and there's DUST - DON'T TAKE THE RISK
Don't cut it, or cut it wet so there's NO DUST - Silicosis Sucks

How should we spell it?
