Mexico's coastal projects combine salt, humidity, intense UV, wind-driven rain and premium finish expectations. A decorative surface described as weather resistant is not enough when concealed fasteners, hinges, locks and electronic penetrations follow a different durability strategy.
Why This Must Be Specified Opening by Opening
A project requirement is useful only when it identifies the opening, intended use, performance target, tested configuration and party responsible for approval. Generic catalogue language cannot resolve different risk zones, wall conditions, hardware sets or operating logic.
Project Specification Checklist
- Exposure statement: Record city, distance from shore, direct spray, prevailing weather, canopy protection and cleaning regime.
- Compatible materials: Coordinate leaf, frame, reinforcement, anchors, fasteners and hardware to avoid galvanic corrosion.
- Finish system: Define preparation, coating layers, edge protection, sample approval and site repair method.
- Smart hardware: Protect readers, cable entries, lock bodies, connectors and backup access against moisture and salt.
- Maintenance: Provide cleaning, inspection, lubrication and touch-up intervals suited to the actual exposure.
Evidence to Review Before Purchase
- Material and finish declarations
- Applicable corrosion or salt-spray evidence
- Approved physical sample
- Maintenance and repair method
Match every report to the exact product proposed. Check dimensions, opening direction, leaf and frame construction, hardware, seals, anchors and supporting wall. Record any difference and obtain formal acceptance before production.
Common Failure Modes
The most common failures are choosing a rating by habit, approving a certificate for another configuration, changing hardware after testing, ignoring the wall interface and leaving commissioning until handover. An opening schedule and evidence matrix expose these gaps while they can still be corrected.
What to Include in the RFQ
Send the destination, project type, door marks, quantities, finished openings, wall construction, required standards, hardware and access-control schedule, finishes, delivery stages and documentation list. This lets the supplier respond with a configuration rather than an unsupported headline claim.

FAQ
Is a supplier declaration enough? No. Request evidence that covers the proposed complete assembly and have it reviewed by the responsible designer and authority.
Can hardware be changed after approval? Only when the evidence or responsible authority permits the substitution. Treat every change as a configuration review.
