What is a continuous hinge used for?

It runs the full height of a door or panel, spreading load across many screws. That stops sagging on tall or heavy doors and makes the edge harder to pry open than with butt hinges.

Is aluminum strong enough for a heavy door?

Aluminum is lighter and rust-free but softer than steel or stainless. It works well for interior doors, cabinets and panels; for a heavy exterior or security door, a steel hinge is the sturdier choice.

What does mill finish mean?

It is bare aluminum straight from the mill, with no paint or anodized coating. It will not rust, but it can show fingerprints and scratches and may oxidize over time.

Can I cut it to a shorter length?

Aluminum cuts easily with a hacksaw or power saw, but you lose the pre-drilled holes past the cut and must drill new ones. Cut square and deburr the edges.

What screws does it take?

The holes are pre-drilled, so match screw size to the hole diameter and to your frame material. Use screws long enough to bite into the frame, not just the door face.

Does it work outdoors?

The aluminum will not rust, but the bare mill finish offers no protection against weathering. For exposed outdoor use, an anodized or coated hinge holds up better.
