North American delivery with strict US code compliance and ocean logistics — a blueprint for replacing imported European systems on US projects.

Your project documents say "Kawneer 1600 System" — what they really require is a set of performance numbers: wind load class, air and water ratings, thermal targets and module geometry. Hanart engineers spec-equivalent unitized and stick-built systems to those numbers, fabricates them in its own Shanghai factory, and delivers worldwide.

Our Approach
Replace the Brand, Keep the Specification
European facade brands like Kawneer built their reputation on engineering consistency and testing discipline. The specification language around them — system type, performance class, test method, finish standard — is exactly what a competent Chinese manufacturer can meet. Hanart's own engineering team, factory and test program are organized around those same parameters.
This page is not a comparison of brand reputations. It is a working specification map: take the performance schedule from your Kawneer-based design, map each line to Hanart's equivalent system, and evaluate the landed cost. Where a requirement needs project-specific proof, we build and test the mock-up.
Hanart Facade is an independent manufacturer. Mention of Kawneer and third-party brand names is for specification identification only; no affiliation or endorsement is implied.
Spec Mapping
Kawneer 1600-Type Specification, Mapped Line by Line
| Project Requirement | Typical Kawneer Spec Baseline | Hanart Equivalent Delivery |
|---|---|---|
| System family | Unitized aluminium curtain wall (1600-type geometry) | Hanart unitized system — same module logic, custom die geometry to your grid |
| Structural wind load | Per project design pressure (ASCE 7 / EN 1991 / local code) | Engineered and mock-up tested to the project's design pressure; class documented |
| Watertightness | Static and dynamic water test per AAMA/EN method | EN 12154 RE-class or AAMA E331-tested; field water test per AAMA 501.1 available |
| Air permeability | EN 12152 AE-class or ASTM E283 leakage limit | AE-class tightness verified; project class documented with independent report |
| Thermal performance | U-value per ISO 10077-2 / EN ISO 12631 | Thermally broken profiles and glazing combos engineered to the target U-value |
| Finish system | PVDF (Kynar-type) or anodized, AAMA 2605-class | PVDF 2–3 coat and anodizing to AAMA 2604/2605 equivalents; color matched |
| Module sizes | Oversized / custom module grid | Same grid geometry; fabrication tolerances and logistics planned for oversize — see the oversized glass system and large-format glass guide |
| Testing & certification | System and project mock-up evidence | Independent accredited laboratory testing (CNAS/UKAS/IAS) before mass production |
Hanart publishes its standard system tests and can run project-specific mock-ups for the exact module and performance targets of your Kawneer-based specification. The equivalence assessment is free and written by engineers, not sales.
Why Buyers Switch
The Chinese Manufacturing Gap
The measurable difference is manufacturing cost: a Shanghai factory with the same CNC lines, die casting and anodizing capacity as Western plants, producing at Chinese labor and energy rates. Buyers consistently see 30–45% savings on landed cost for spec-equivalent systems, before installation logistics.
The savings do not come from cutting engineering. Hanart holds Grade-I contracting and Class-A design qualifications, ISO 9001/14001/45001 management systems, and has delivered facades from New York to Mongolia. The same engineers who review your Kawneer schedule will write the Hanart equivalent — one accountable counterparty.
Why the Market Is Moving
- Spec-equivalent systems at 30–45% lower landed cost
- Fabrication, logistics and installation under one contract
- Project-specific mock-up tests at accredited laboratories
- DDP / CIF terms to 40+ countries, including USA and UK

FAQ
Compliant Process
The compliant way to propose an alternative
Proposing a brand alternative to a named specification is a normal, regulated part of facade procurement. The professional route is a line-by-line performance comparison — not a claim about the other brand. Hanart maps each specified system to its engineered equivalent, submits the comparison with test evidence, and lets the approval process decide.
Kawneer and its product names are trademarks of their respective owners. This page is an independent comparison written for procurement teams; Hanart is not affiliated with, sponsored by or endorsed by Kawneer, and the alternative systems described are Hanart's own engineering.

Delivery
What you receive with a Hanart alternative
An engineered alternative arrives as a complete package: performance specification, engineering calculations, factory QA records, delivery plan and installation drawings, plus the same documentation and warranty as our standard projects — one contract from engineering to erection.
Value
Where the value comes from
An engineered alternative reduces landed cost in three places consumers expect: lower fabrication and logistics cost from the Shanghai plant, fewer change orders because the system is rationalized to the contractor's own production line, and a single responsible contract that removes coordination overhead between multiple suppliers.

Yes, when the specification is performance-based, which it normally is. Hanart engineers map each line — wind load, air, water, thermal, finish, module geometry — to an equivalent system and prove it with project-specific mock-up testing before production.
Typical landed-cost savings are 30–45% for spec-equivalent systems, depending on glass spec, finishing and logistics route. The equivalence assessment includes a line-by-line cost comparison — you see the arithmetic before committing.
Hanart tests at accredited independent laboratories (CNAS, UKAS or IAS equivalents) and documents every claimed class. If the project requires a specific certification scheme, we plan for it in the mock-up program.
Yes. Custom die geometry, oversized module fabrication and color-matched PVDF/anodizing are routine for Hanart's landmark portfolio — including curved and free-form envelopes.
