A pool fence is a safety barrier governed by code, not a design choice. Almost every dimension on it is prescribed.
Pool barriers are typically specified for minimum height, maximum gap under the fence, maximum picket spacing, no climbable horizontals on the outside, and a self-closing, self-latching gate that swings away from the pool.
Any in-ground or permanent above-ground pool, and often spas, depending on jurisdiction.
Aluminium and vinyl are common because both are finish-free and both are made in code-compliant profiles. Mesh removable barriers are used where a permanent fence is not wanted.
This is the one fence category where code is the whole specification. Requirements are set locally and by adopted safety codes, and inspection is often part of the pool permit rather than a fence permit.
Usually tied to the pool project schedule, since the barrier is frequently a condition of the pool's final inspection.
The gate is the safety-critical component. Self-closing hinges and self-latching hardware are wear items and should be tested regularly rather than annually.
It is set by the code your jurisdiction has adopted, and the local building department is the authority. Do not build to a number found online without confirming it locally.
Pool barrier codes generally require the gate to swing outward, away from the pool, and to be self-closing and self-latching with the latch out of a small child's reach.
Sometimes, if it meets every barrier requirement including gap, height, climbability and gate hardware. It is inspected against the barrier code, not against the fence code.
