Your Trusted Partner For World-class Door Solutions
| Item | Description |
|---|---|
| Project Type | Luxury Villa Complex |
| Units | 48 villas, each 2–3 stories |
| Location | Island, Southeast Asia |
| Scope of Supply | Steel entry doors, interior steel doors, aluminum bathroom doors |
| Local Conditions | High humidity, salt spray (coastal), heavy rain, typhoon season |
| Applicable Standards | Local building codes, corrosion resistance (ASTM B117), fire safety where applicable |
The developer – a high-end residential builder – sought a single, reliable door supplier that could deliver durable, rust-proof, and aesthetically consistent doors for a villa complex targeting affluent buyers. The island location meant logistical complexity and extreme environmental demands.
The project was located on a tropical island in Southeast Asia, with direct exposure to sea breeze. The developer faced several specific challenges:
Coastal corrosion – Salt-laden air rapidly degrades standard steel doors. Rust spots, peeling coatings, and lock seizure are common problems in this environment.
Heavy rainfall & humidity – Door frames must prevent water ingress; interior doors need to resist warping or swelling despite 80–90% average humidity.
Typhoon resistance – The region experiences typhoons with wind speeds >150 km/h. Entry doors require high impact resistance and robust sealing.
Aesthetic consistency across 48 villas – The developer demanded a uniform look: modern, minimalist design with dark neutral colors (e.g., RAL 7016, matte black). Inconsistent finishes would hurt the luxury positioning.
Mixed material supply – The project needed steel entry doors, interior steel doors, and aluminum bathroom doors. Sourcing from three different suppliers would complicate logistics, quality control, and after-sales support.
Island logistics – Limited port capacity and last-mile road conditions required careful packing and shipment coordination. Any delay would push back the entire villa handover.
Several local suppliers offered solutions, but none could provide all three product types with corrosion-resistant specifications and design uniformity.
TOF DOOR activated its trust-based problem-solving approach, acting as a one-stop safety partner rather than a mere product supplier.
| Product | TOF Specification | Why it matters |
|---|---|---|
| Steel entry doors | 1.5mm hot-dip galvanised steel + heavy-duty polyester powder coating (1,000h salt spray tested) | Prevents rust even in direct sea breeze |
| Weather sealing | Triple silicone gaskets + stainless steel threshold | Typhoon-proof water & air tightness (tested to 150 km/h wind pressure) |
| Locking system | Stainless steel 3-point multi-lock (marine grade) | No corrosion on lock cylinders or latch bolts |
| Interior steel doors | 0.8mm pre-painted galvanised steel, honeycomb core | Lightweight, rust-free, sound absorbing for bedroom privacy |
| Aluminum bathroom doors | 6063-T5 aluminum frame + frosted tempered glass + stainless steel hinges | Zero rust, moisture-proof, modern aesthetic |
Provided RAL 7016 (anthracite grey) for all steel doors and matt silver anodized for aluminum bathroom doors.
Concealed hinges and flush surfaces on steel doors – matched the villa’s minimalist architecture.
Delivered sample doors (1 of each type) within 18 days for developer approval. Once approved, mass production ensured identical finishes across all 48 villas.
Provided ASTM B117 salt spray test reports (1,000 hours) for coating – independently verified.
Shared material certificates for galvanised steel and aluminum alloy.
This documentation gave the developer full confidence that doors would remain rust-free for years.
Instead of sourcing steel entry doors, interior steel doors, and aluminum doors from 3 different vendors, the developer placed a single purchase order with TOF DOOR.
TOF managed all three production lines and consolidated shipment – reducing the developer’s coordination workload by an estimated 60%.
Packed doors with VCI (vapor corrosion inhibitor) film + edge protectors + pallet shrink-wrap.
Shipped from Ningbo port to Batam / Bali / Phuket (depending on island location) via direct LCL service.
Worked with a local last-mile trucking partner experienced in narrow island roads.
Delivered in two batches (24 villas each) to match construction pace – avoided on-site clutter.
Provided 5-year anti-corrosion warranty – a rarity for coastal projects.
Sent a TOF technical supervisor for on-site installation training (first 5 villas).
Set up a local spare parts stock (extra seals, hinges, lock cylinders) for fast replacement.
| Metric | Outcome |
|---|---|
| Corrosion resistance | After 6 months in service, no rust spots or coating failure reported (client inspection) |
| Typhoon performance | During a Category 2 typhoon, all TOF entry doors remained sealed with zero water ingress |
| On-time delivery | Both batches arrived within ±3 days of planned schedule |
| Client coordination saving | 60% less procurement effort compared to using multiple door suppliers |
| Design consistency | All 48 villas delivered with identical door finishes – no visual deviation |
| Post-sales support | Only 2 minor adjustments requested (hinge tightening) in first 6 months |
Client testimonial (Project Director, Island Villas Development):
“In this environment, most doors start showing rust within a year. TOF gave us test reports, real samples, and a warranty that proved they understood our problem. And they delivered everything – entry doors, interior doors, even bathroom doors – as one package. That’s not just a supplier. That’s a partner.”
