PoolFIX coated is the primary PoolFIX system for approximately 95% of suitable applications. This market position never replaces product-specific validation.

When no validated product/application rule matches, the result is Technical review required.

Why PoolFIX coated?

Volume & price estimate

Available in multiple pool colours

Which coating build-up suits your pool?

Assess which finish suits your pool.

Tilework can create recurring maintenance questions.

A project-specific route to a seamless finish.

Traditional tilework versus ACRATON® Dolphin

Bolts, nuts and screws form part of a larger assembly. Their suitability depends on material, coating, geometry, load, substrate, exposure and installation. Review the product specification and the actual application together.

Application

Prepare draft wording that records application, load, substrate, exposure, installation method, inspectability and available product documentation. Open issues remain visible until assessed by an authorised project party.

This draft records the entered assumptions and open issues. Following a specification does not automatically remove individual duties, a duty to warn or liability. Have material selection and execution assessed for the project.

Summary — ready to generate

Project dossier contains: specification.pdf · specification.docx · checklist.pdf · order-list.pdf (with QR codes to the webshop) · README.txt — ideal for architects and contractors.

Common stainless-steel grades and other metals may have limitations in certain pool conditions. Assess material, load, location, exposure and installation against the applicable requirements and verified product information.

Material selection requires project-specific assessment

Support for your specification

A2 and A4 are considered corrosion-resistant materials in many general construction and installation applications. A swimming-pool hall, however, is an exceptional environment in which chloride load and tensile stresses can lead to stress corrosion cracking.

‘But it’s stainless steel, isn’t it?’ is not a material justification in a swimming pool.

For everyone who must be able to justify material choices in a swimming pool.

Material safety in swimming-pool environments

Can you substantiate the material choice for each location?

Do not use 1.4529 as a universal replacement. Before selection, confirm that a current, approved product-specific rule covers the exact location and application.

PoolFIX guideline for 1.4529 HCR

Even highly alloyed stainless steel is not entirely risk-free.

Stainless steel can develop hidden cracking in a pool environment.

The right question is: which material belongs in this specific location?

A research result is usable only within its described method and conditions and is not an individual failure probability for every pool.

Common stainless steels such as A2/304 and A4/316 may be susceptible to stress corrosion cracking under tensile stress and chloride exposure.

1.4529 HCR is not a universal solution. Use only within a verified product-specific rule and project assessment.

Check the coating specification and application limits for the exact item and project.

Research questions reveal application limits.

From general fastening to demonstrable material selection.

General approach

PoolFIX approach

After an incident, can you demonstrate why this material was selected?

That is why material selection in a swimming-pool environment must be based on application, exposure and demonstrable suitability — not only on the term ‘stainless steel’.

The danger is not always visible from the outside.

Applicable requirements depend on the project country, authority and technical specification. No standard automatically approves a PoolFIX product.

Standards, codes and guidance

Not automatically applicable as UK or US law

NEN 9200 (Dutch technical reference — local applicability requires validation) is a Dutch standard and does not automatically approve a product or establish local law outside the Netherlands.

The responsible project team must establish applicable local requirements and product-specific application validation.

This product no longer exists or is inactive.

References

Non-standard, overhead, suspended or insufficiently documented applications require project-specific technical review. 1.4529 must never be used overhead or suspended.
