What can this mesh screen be used for?

It works as protective netting on fences, railings, garden beds and openings. It is not a framed panel, so plan on fixing it to an existing structure.

Will stainless steel mesh rust outdoors?

Stainless steel resists rust far better than plain steel or plastic netting. It still holds up best when water can drain and debris does not sit against it.

How do I cut it to size?

Use tin snips or aviation shears for short runs and wear gloves, since cut edges are sharp. For long straight cuts, a angle grinder with a thin disc is faster.

Does it come with mounting hardware?

No. Expect to supply your own staples, clips, ties or screws, and check the mesh size suits the fasteners you plan to use.

Is it strong enough to contain a dog?

It is stronger than plastic netting but still a flexible mesh. For a determined dog, fix it firmly to a rigid frame or fence and check the mesh opening against the animal's size.
