Custom Doors & Windows Manufacturer FAQs

Fortor Security Door Co., Ltd. is a direct manufacturer operating a 20,000 square meter facility in Guangdong, China, backed by over 17 years of specialized door and window engineering experience. Unlike trading intermediaries, we execute all key manufacturing steps under one roof—including aluminum profile CNC machining, thermal break strip insertion, double/triple glazing assembly, hardware calibration, and protective export packing.

Our dedicated technical department reviews shop drawings, wind load metrics, and thermal insulation targets for every project, ensuring specifications match local site conditions prior to cutting any profile.

We supply custom-engineered aluminum openings for luxury residential villas, multi-family housing developments, coastal resort hospitality projects, and commercial storefronts in over 30 countries.

Our core product portfolio includes thermal break casement windows, tilt and turn windows, lift-and-slide patio doors, heavy-duty bi-fold doors, structural glass curtain walls, motorized retractable sunrooms, and louvered aluminum pergolas.

Yes. Over 80% of our production volume is delivered to international markets including the United States, Canada, Australia, the United Kingdom, and the Caribbean islands. We design our window and door systems with deep profile depths, multi-gasket perimeter sealing, and structural reinforcement to meet stringent local climatic challenges, such as hurricane wind pressures, tropical humidity, and freezing northern winters.

Absolute customization is standard at Fortor Security Door Co., Ltd. We manufacture every unit strictly according to your architectural schedule and rough opening dimensions. Available customization options include:

• Profiles & Finishes: Thermal break polyamides (PA66GF25), architectural powder coatings (AkzoNobel / PPG), anodized finishes, and fluorocarbon (PVDF) coastal coatings.
• Glazing Systems: Double or triple insulated glass, Low-E coatings, argon gas filling, warm-edge spacers, acoustic laminated glass, and hurricane impact-resistant tempered laminated glass.
• Hardware: German premium multi-point locking systems (Siegenia, Hoppe, GU, Roto) or heavy-duty custom architectural handles.

Our certified system series are tested against recognized global standards. Depending on the selected system and project scope, test documentation includes:

• North America: NFRC thermal performance ratings (U-Factor, SHGC, Air Infiltration) and CSA / AAMA structural testing.
• Australia & New Zealand: AS 2047 and AS 1288 structural wind pressure, water penetration, and glass safety standards.
• Quality Assurance: Factory operations are certified under ISO 9001 quality management standards.

We issue third-party test documentation upon project review to support local permit and tender submittals.

System selection depends on climate exposure, structural opening dimensions, and operational requirements:

• Casement & Tilt-Turn Windows: Offer maximum air and water tightness due to multi-point compression gaskets, making them ideal for high-rise buildings and extreme cold or coastal zones.
• Lift & Slide Doors: Engineered for wide patio openings where large glass panels lift off gaskets to slide effortlessly, locking down securely when closed.
• Bi-Fold Doors: Maximize unobstructed indoor-outdoor transitions for residential terraces and hospitality venues.

Dimensional and specification mismatches are eliminated through a rigorous pre-production CAD review process. Before profile cutting begins, our engineering team generates comprehensive 2D/3D shop drawings showing outer frame sizes, glass thickness, sash handing, sill thresholds, drainage paths, and installation anchor points. Fabrication proceeds only after formal client drawing approval.

To receive a prompt and detailed technical proposal, please provide:

1. Architectural elevation drawings or rough opening window/door schedules.
2. Preferred opening styles (e.g., casement, sliding, folding, tilt & turn).
3. Glass specifications (e.g., double Low-E, laminated, clear, tinted).
4. Frame finish color and coating type.
5. Project location (city/country) and required performance standards (e.g., NFRC, AS 2047).

Standard fabrication lead time is 25 to 35 business days following final CAD shop drawing sign-off and deposit confirmation. Specialized custom extrusion dies or unique powder coat colors may require an additional 7 to 10 days. A fixed production timeline is established so project sites can schedule installation predictably.

Every window and door manufactured by Fortor Security Door Co., Ltd. undergoes a 100% pre-shipment assembly test in our workshop. QC technicians inspect outer dimensions, diagonal squareness, gasket compression, hardware operation, coating adhesion, and water seal performance. High-resolution inspection photos and video recordings are shared with the buyer prior to final export crating.

Export packaging is engineered for long-distance sea freight and multi-point handling. Windows and doors are wrapped in protective film, fitted with heavy-duty foam corner guards, layered with shock-absorbing cardboard, and secured inside fully enclosed, fumigated wooden crates or steel transport racks designed for safe forklift handling on-site.

We deliver comprehensive technical support during your site installation stage, providing structural mounting diagrams, detailed assembly drawings, and remote video guidance. Local showroom access and partner networks in selected international regions further ensure prompt technical responsiveness.
