How do aluminum door sills work?
How do you make an aluminum door slide into place?
It’s a complex task and it can take hours.
You could spend days and hours just getting it to slide in place.
That’s because aluminum sills are made by an alloy of aluminum and carbon that are mixed and then poured together into a hollow structure.
The aluminum siding then forms the hollow aluminum sheet that fits into the aluminum door slot.
To make an adequate aluminum sill, aluminum is poured into a specially designed mold.
It’s like a special oven that is heated to the melting point of aluminum.
To get the right shape and thickness, the mold is heated until the mold forms a solid sheet of aluminum sheet.
This process requires precise control and care.
How do the sills fit together?
Aluminum sills typically fit tightly together, but some do not.
Some are too loose and others are too tight.
If the sill isn’t well built, it could break or shatter.
If it doesn’t fit well, it may fail, and it could crack or damage the aluminum sideropod.
How does an aluminum siller work?
The aluminum door is a special alloy of carbon and aluminum.
When you put a door into an aluminum slot, a hole opens up in the top of the door.
As the carbon is pushed out of the hole, the hole opens again and the carbon inside the slot expands.
The carbon in the hole then moves outward toward the edge of the slot.
The metal that’s in the slot keeps the door from sliding back into place.
Once the door is in place, the carbon doesn’t expand and the door slides into place, keeping the door open and ready to go.
