Ground-level pool edge
Check the exact product-specific coated rule first. A restricted 1.4529 route exists only for a pre-approved application within the distance limit.
The primary PoolFIX solution for approximately 95% of suitable applications
PoolFIX coated fasteners for natatoriums
PoolFIX coated is the preferred PoolFIX fastening system for most suitable natatorium and aquatic-facility applications. It combines application-specific material selection with product documentation and project traceability. Alloy 926 / UNS N08926 is reserved for restricted ground-level applications within 3.3 ft (1.0 m) of the water.
Why selection matters
Stress corrosion cracking can develop without an obvious surface warning
A susceptible material, chloride exposure and tensile stress can combine in a natatorium. Product selection must therefore use the exact location, exposure, load, geometry and maintenance conditions.
Source: research carried out by PoolFIX in collaboration with Koninklijke BAM for the municipality of Tilburg.
Actual susceptibility remains dependent on factors including tensile stress, chloride load, temperature, geometry, exposure, location and maintenance conditions.
Primary material route
PoolFIX coated is assessed before every restricted exception
PoolFIX coated carries approximately 90–95% of the commercial focus because it is the primary PoolFIX solution for most suitable applications. An actual recommendation still requires a validated product-specific rule.
See the selection sequence- 1. Validate PoolFIX coated
Match product, placement, exposure, application and load against an approved rule.
- 2. Assess the 1.4529 exception only if needed
Ground level, within 3.3 ft (1.0 m), known application and pre-approved scope.
- 3. Fail closed when evidence is missing
The result becomes Technical review required — never an assumed recommendation.

Why A2/A4 is not an automatic answer
304 and 316 can remain susceptible in pool atmospheres
Material grade alone does not describe tensile stress, chloride deposits, temperature, geometry or cleaning. PoolFIX selection starts with the application rather than a generic stainless-steel label.
Understand the riskRestricted exception
1.4529 HCR / Alloy 926 is not a universal solution
Pre-approved ground-level applications only, within 3.3 ft (1.0 m) of the water. Never roofs, ceilings, overhead, suspended services or hanging equipment.

Supplied product references and documentation without claiming application approval.
Batch traceability
Batch traceability where applicable, linked to the actual supplied article.
Technical review
A clear escalation route when application evidence is incomplete.

Application review scenarios
The location changes the decision route
Ceiling or suspended service
1.4529 is excluded before distance is considered. PoolFIX coated also requires an explicit validated product rule; otherwise technical review is mandatory.
Existing installation
Record product, location, load, exposure, cleaning and available documentation before deciding whether inspection, replacement or further review is required.
Frequently asked questions
Material selection in natatorium environments
Is PoolFIX coated automatically suitable for every application?
No. It is the primary commercial PoolFIX system, but an automatic recommendation requires a validated product-specific application rule.
Is Alloy 926 / 1.4529 the premium PoolFIX option?
No. It is a restricted exception for pre-approved ground-level applications within 1.0 metre / 3.3 ft of the water.
Can 1.4529 be used for a ceiling point close to the water?
No. Roof, ceiling, overhead and suspended exclusions always take precedence over distance.
What if the exact location or load is unknown?
The selector returns Technical review required and does not make an automatic product recommendation.
