Material selection in commercial projects is rarely just about performance. It is about compliance, accountability, and reducing risk across the project lifecycle.
While stainless steel systems are increasingly being specified in place of copper, one critical factor is often overlooked:
Not all stainless steel press systems are CodeMark certified.
Specification decisions carry compliance risk
In many projects, stainless systems are specified by consultants and later tendered and installed by contractors.
That means the original specification decision sets the direction for procurement, installation, inspection, and long-term performance.
If a system is questioned during approval or inspection, the scrutiny often traces back to the specification.
Certification plays a key role in reducing that risk.
What CodeMark certification actually means
CodeMark is a nationally recognised product certification scheme that verifies compliance with the New Zealand Building Code.
For stainless steel pipe systems, CodeMark certification confirms that:
- The system has been independently assessed
- It complies with relevant Building Code clauses
- Supporting documentation is formally reviewed and maintained
- Ongoing compliance is monitored
This is more than a manufacturer's declaration. It is a third-party verification.
For consultants, this assures that the system meets regulatory requirements before it reaches the site.
“All stainless is the same”
From a distance, stainless steel pipe systems can appear similar. Press fittings look alike. Materials are described in comparable terms.
However, compliance frameworks differ.
Not all stainless steel press systems available in the New Zealand market are CodeMark certified.
That difference may not be visible during tender, but it can become significant during:
- Building consent review
- Inspection and sign-off
- Post-installation compliance queries
Certification reduces uncertainty before those questions arise.
Why certification supports smoother project delivery
For consultants, specifying a CodeMark-certified system can:
- Reduce approval friction
- Minimise documentation challenges
- Provide clearer compliance pathways
- Strengthen the defensibility of specification decisions
For contractors, it can mean fewer compliance-related disruptions during installation.
For asset owners, it supports long-term confidence in system performance and regulatory alignment.
Certification is not about marketing. It is about risk management.
The KE KELIT stainless advantage
KE KELIT’s stainless steel press system is CodeMark certified.
This provides confidence from specification through to installation and sign-off across commercial applications.
When stainless steel is being considered as part of a material strategy, whether for price stability, durability, or performance, certification should form part of the evaluation criteria.
Not all systems offer the same level of verified compliance.
Confidence begins at specification stage
As stainless steel continues to gain traction in commercial, mechanical and hydraulic projects, specification decisions carry increasing weight.
Performance matters. Installation efficiency matters. Long-term durability matters.
But so does verified compliance.
When evaluating stainless steel systems, confirming CodeMark certification early can reduce downstream risk and strengthen project outcomes.
