Project Challenge
Building The One Nai Harn in a coastal area like Rawai, Phuket brings unique challenges. The seaside environment, hotel-level expectations, and a tight construction schedule all place higher demands on materials, systems, and coordination. Below are the key challenges the project needed to address.
Corrosion Risks from Salt Air and Humid Coastal Climate

Coastal air contains salt and moisture that can quickly damage standard aluminum systems. In Phuket’s humid seaside climate, corrosion is a long-term risk that affects both appearance and performance. Without proper protection, aluminum profiles, hardware, and fixings may deteriorate, leading to higher maintenance costs and a shorter service life.
High Durability Requirements for Aluminum Profiles, Hardware, and Fixings

Hotel projects require materials that can withstand constant use and environmental stress. Doors, windows, and balustrades are opened, closed, and exposed daily. This means aluminum systems must offer long-term structural strength, stable finishes, and hardware that performs reliably without frequent replacement or adjustment.
Hotel-Grade Standards for Comfort, Safety, and Appearance

As a hospitality project, The One Nai Harn must meet higher standards than typical residential buildings. Guests expect smooth operation, quiet performance, and a premium look. At the same time, safety is critical, especially for glass balustrades and exterior openings. All systems must balance aesthetics, comfort, and compliance with hotel requirements.
Tight Construction Timeline with Staged Delivery and Installation

The project follows a strict construction schedule, leaving limited time for on-site adjustments. Windows, doors, and balustrades need to be delivered in stages to match installation progress. Any delay in production or mismatch in dimensions could slow down the entire build and impact overall timelines.
Need for Precise Coordination Between Factory Production and Site Works

With multiple systems being installed across different areas of the hotel, coordination is essential. Factory production must align closely with on-site installation plans. Accurate manufacturing, clear documentation, and reliable delivery scheduling are key to reducing rework and ensuring a smooth installation process.
Solution
To overcome the challenges of a coastal hotel environment, we delivered a tailored, performance-driven solution designed specifically for long-term use in Phuket’s seaside conditions. Every system was selected and engineered with durability, efficiency, and hotel-grade standards in mind.
Customized Aluminum Window and Door Systems for Coastal Use

We provided custom aluminum window and door systems designed to perform in humid, salt-rich environments. Profile structures, drainage details, and sealing systems were optimized for coastal conditions, helping protect against moisture ingress while maintaining clean, modern lines that suit the hotel’s architectural style.
Corrosion-Resistant Finishes and Compatible Hardware Selection

All aluminum profiles were treated with corrosion-resistant finishes suitable for seaside exposure. Hardware and fixing accessories were carefully matched to these finishes to avoid galvanic corrosion. This ensures smooth operation, stable performance, and a longer service life with reduced maintenance needs.
Glass Balustrade Systems Engineered for Safety and Durability

For balconies and common areas, we supplied glass balustrade systems designed to meet hotel safety standards. The systems combine strong structural support with clear, open views, while using materials and fittings built to withstand constant exposure to wind, moisture, and salt air.
Factory-Controlled Manufacturing for Accuracy and Consistency

All products were manufactured under controlled factory conditions, allowing for precise cutting, assembly, and finishing. This approach ensures consistent quality across all units, reduces dimensional errors, and improves installation efficiency once products arrive on site.
Pre-Delivery Quality Inspections to Reduce On-Site Installation Time

Before shipment, each system underwent strict quality inspections, including checks on dimensions, finishes, and hardware compatibility. This pre-delivery process minimizes on-site adjustments, supports faster installation, and helps the project stay on schedule.
Outcomes / Performance

The systems installed at The One Nai Harn have delivered strong results across performance, appearance, and project efficiency. From installation through ongoing use, the solutions are meeting the expectations of a modern coastal hotel.
Smooth installation aligned with the construction schedule
Products were delivered in stages and installed as planned, helping the project move forward without delays or disruptions.
Strong corrosion resistance for long-term seaside exposure
The aluminum systems and hardware are performing well in the humid, salt-rich environment, supporting long service life with lower maintenance needs.
Consistent visual appearance for modern hotel design
Clean lines, stable finishes, and uniform detailing help maintain a high-end look across guest rooms, balconies, and shared spaces.
Improved installation efficiency with fewer on-site adjustments
Accurate factory production and pre-delivery checks reduced the need for rework, saving time and labor on site.
Systems meeting hotel standards for safety, comfort, and reliability
Windows, doors, and glass balustrades deliver smooth operation, secure performance, and a comfortable guest experience.
Lessons Learned & Best Practices

This project highlights several best practices for coastal hotel developments, especially in humid and seaside environments.
Select materials early for coastal conditions
Early decisions on aluminum systems, finishes, and hardware help avoid costly changes later.
Use corrosion-resistant systems to extend lifecycle
Proper finishes and compatible hardware reduce long-term maintenance and protect visual quality.
Rely on factory quality control to improve efficiency
Controlled manufacturing and inspections shorten installation time and improve overall project flow.
Plan staged delivery for tight hotel schedules
Phased shipments support smooth installation and better coordination with site progress.
Choose custom solutions over standard systems
Tailored aluminum and glass systems perform better than off-the-shelf products in harsh coastal environments.
