Hi Folks,
Long time follower, first time poster, so thanks for the help over the years! Looking for a bit of assistance with a balcony I’ve designed and am about to fab up for my house - Sketch attached (3m x 1.4m overall). It's all carbon steel including the handrails and the plan is to galvanise and powder coat black. I didn’t want to use off the shelf stainless posts – prefer the integrated look of all coated the same colour. The floor will be laminated walk on glass, sealed in place so that it acts as a roof/porch to the utility entrance below. The glass will fall away from the door threshold to the 200x100 RHS which I’ll be using the internal of as a hidden gutter (no trees so it won’t get blocked). It’s insanely over designed… but then that’s a common theme with the structural engineer I’m stuck with! I took inspiration from the below balcony by Bradfabs.

Question I have is around the glass clamps for the hand rail. I plan to use the following weld on ones from DC Iron along with 10mm thick toughened glass.

They have a 15.3mm diameter nylon spacer/bush but what hole should I be specing in the glass to match? If I go 16mm it leaves me no wiggle room for fab tolerances. I wondered about a 20mm hole since that gives me plus/minus 2.5mm of float which would be more than enough and allow for movement due to differential expansion between steel and glass on hot/cold days. Can anyone share their experience in this area?
Any help much appreciated,
Thanks
Michael
