Product Features
Engineered for the specific demands of outdoor residential and commercial environments, Hotian aluminum patio and bifold door systems deliver smooth daily operation, durable weather performance, and lasting visual quality across every application.
Why Choose US
With advanced manufacturing capabilities, strict quality control, and professional customization services, we deliver superior patio doors meeting international market demands.
Professional Manufacturing
Our dedicated patio and bifold door production lines use CNC precision profile cutting, automated corner crimping, and skilled frame assembly with inline dimensional verification — delivering consistent accuracy across every panel in a single residential door and across hundreds of units in a large development package.
Engineering Team
Our in-house engineering team provides complete project technical support: shop drawings, glass performance calculations, structural wind load documentation, NFRC thermal simulation data, and installation details for every project. Full documentation packages for building permit submissions and green rating certifications are available on request.
Premium Material Sourcing
We source 6063-T5/T6 aluminum extrusions, certified Low-E glass units with warm-edge spacers, stainless steel hardware, and EPDM seal profiles from established, audited suppliers. All materials undergo incoming inspection before production begins, ensuring consistent performance specifications are maintained throughout your project.
Competitive Factory Pricing
Direct factory procurement from Hotian consistently delivers significant cost advantages on project supply compared to local distributor pricing. For development contractors and property groups, the margin improvement across a full patio door package is substantial. For homeowners ordering a single custom bifold door, factory-direct pricing means premium system quality at a price that local fabricators and dealers cannot match.
Reliable Production Lead Times
Standard custom residential orders are completed within 3 to 5 weeks. Development packages are scheduled through our dedicated project management system with regular production milestone updates. Our production capacity is planned quarterly, so early engagement is recommended to secure your program dates.
Complete Export Service
Our export team manages commercial documentation, protective export crating, and container loading for international project deliveries. Bifold panels and sliding systems are individually film-wrapped with foam corner protection and crate-packed for safe international transit. Single homeowner orders are dispatched in reinforced packaging with full installation guides included.

Frequently Asked Questions
Find answers to common questions about our patio door customization, manufacturing process, quality standards, and export procedures.
What is the difference between a bifold door and a sliding patio door?
A bifold door folds in concertina panels along a top or bottom track, stacking neatly to one or both sides to create a fully open connection between indoor and outdoor spaces. A sliding patio door moves one or more panels horizontally on a track without folding. Bifold concertina systems provide a wider clear opening and better suit locations with sufficient wall space to stack folded panels. Sliding and lift-and-slide systems are preferable where stacking space is limited or where very large, heavy glass panels are specified.
What is the difference between a top-hung and bottom-hung bifold door system?
Top-hung bifold doors are suspended entirely from the overhead track with no bottom rail crossing the floor — creating a completely clear, flush threshold ideal for seamless indoor-outdoor transitions, accessibility compliance, and pool deck applications. Bottom-hung systems run on a bottom track, providing greater structural support for wide-span or heavy glass configurations. We specify the appropriate system based on your opening width, panel weight, threshold requirement, and project application.
What U-factor and SHGC values can your thermally broken patio doors achieve?
Our thermally broken aluminum systems with Low-E double glazing and argon fill achieve center-of-glass U-factors from 1.1 W/m²K (or 0.19 BTU/hr·ft²·°F in NFRC units) and SHGC values configurable from 0.20 to 0.55 depending on your climate zone. High-performance triple-glazed configurations achieve whole-window U-factors below 0.28 for ENERGY STAR Most Efficient and California Title 24 compliance. Thermal simulation data and NFRC product ratings can be provided for permit and certification submissions.
Can you supply thermally broken patio doors for cold climate and high-altitude projects?
Yes. We engineer cold-climate patio door specifications combining 34mm thermal break frames, triple glazing with krypton or argon fill, warm-edge spacer systems, and enhanced EPDM compression seals to meet the demanding U-factor requirements of northern North America, Scandinavia, alpine, and high-altitude project locations. Passive House level performance configurations are available on request.
What is the maximum width for aluminum bifold door systems?
Standard bifold configurations span up to 8m using 8-panel arrangements on a single track. For openings up to 12m or beyond, we engineer multi-section systems with structural intermediate posts or transom beams meeting the required wind resistance and structural load classifications for your building height and location. Structural engineering documentation is available for building permit submissions.
Are your patio doors suitable for coastal and marine environments?
Yes. For coastal installations within 1km of the ocean, we specify marine-grade AA25 anodized frame finishes, Grade 316 stainless steel hardware throughout, heavy-duty EPDM double compression seals, and enhanced drainage channels — providing maximum protection against salt air corrosion and ensuring long-term performance in high-humidity marine environments.
Can you match a specific RAL frame color specified by an architect or designer?
Yes. Our powder-coat facility applies any RAL Classic or RAL Design color to aluminum frame components. For dual-color requirements — where the interior and exterior face of the frame are specified in contrasting colors — we apply separate coating batches with masking to achieve a clean, precise color separation at the thermal break line. Dual-color is particularly popular for projects where an exterior black frame is paired with an interior white or natural finish.
Do you supply insect screen systems with patio and bifold doors?
Yes. Retractable pleated insect screen systems, fixed frame screens, and corner-stacking screen wall systems are available as integrated additions to most patio and bifold configurations. Screen tracks are extruded into the door frame system for a clean, coordinated appearance, avoiding the unattractive bolt-on screen frames common in aftermarket products.
Can you supply matching windows and entry doors in the same order?
Yes. We regularly supply complete project window and door packages combining aluminum patio and bifold doors with matching casement and sliding windows, fixed glazing, and entrance doors — all coordinated in the same frame profile series, powder-coat color, glass specification, and hardware family for a unified facade and interior aesthetic.
Can homeowners order a single custom patio or bifold door?
Yes. Single residential orders are welcome with no minimum quantity. Homeowners and interior designers order directly from our factory at the same quality standard as our development project supply. We offer a sample panel program for residential clients who wish to see and handle the actual frame profile, color, and glass before approving their full custom order.
What is the lead time for custom patio and bifold door orders?
Standard residential custom orders — including single homeowner orders — are completed within 3 to 5 weeks from shop drawing approval and deposit. Development project packages are scheduled on a project basis with phased production releases available for floor-by-floor or unit-by-unit delivery programs. Ocean freight to most international destinations adds 3 to 4 weeks to the production period. Express air freight options are available for urgent single-door orders.
