Aluminium bifold doors prices depend on the series, size, glass package, hardware and finish. WANJIA Hiseng builds four aluminum folding door series: 68, 75, 80 and 88. Each series suits different openings and performance needs. This guide explains what drives cost and how to get an accurate quote for your project.
What Affects Aluminium Bifold Doors Prices
Several factors move the final price. The most important is the series. The 68 series is a lighter, more economical option for interior openings or smaller patios. The 88 series uses a 2.0 mm aluminum profile with 2.2 mm local reinforcement, which adds material cost but improves stiffness for tall or wide openings. Sash width ranges from 500 to 900 mm and height from 1900 to 3000 mm, so a larger door with more panels costs more than a compact two-panel unit.
Glass is another major cost driver. Standard glazing for the 88 series is 5+27A+5 tempered insulated glass. Upgrading to low-E, laminated or triple glazing increases the price. Hardware also matters. Kinlong is the standard hardware brand, while Hoppe, Cmech, VBH and G-U are available as upgrades. Finish options include powder coating in multiple colors, and special finishes add cost.
Order volume and shipping terms affect the final landed price. WANJIA Hiseng quotes within 3 hours after receiving project details. Lead time is usually 25-30 business days, depending on the design, materials and order volume.
Series Comparison and Price Positioning
Each series targets a different balance of price and performance. The table below summarizes the key differences. Use it as a starting point, not a final quote. Your exact aluminium bifold doors prices will depend on your opening size and options.
| Series | Typical Use | Profile | Standard Glass | Hardware |
|---|---|---|---|---|
| 68 | Interior or small patio | Lighter aluminum | Insulated glass | Standard |
| 75 | Residential patio | 2.0 mm aluminum | 5+27Ar+5 tempered | Aosi |
| 80 | Wide openings | Reinforced aluminum | Insulated glass | Kinlong standard |
| 88 | Large or high-traffic openings | 2.0 mm + 2.2 mm reinforcement | 5+27A+5 tempered | Kinlong standard, Hoppe, Cmech, VBH, G-U |
The 75 series insulated folding door uses 2.0 mm aluminum with matte black powder coating and 5+27Ar+5 tempered glass. Its Uw value is 3.5 W/m²K and Rw is 25 dB. The 88 series is ENERGY STAR certification-backed, which can matter for projects that need documented thermal performance.
Hardware and Glass Upgrades
Hardware has a direct effect on both price and long-term reliability. The standard hardware on the 88 series is Kinlong. For projects that require a specific brand, WANJIA Hiseng can supply Hoppe, Cmech, VBH or G-U. These upgrades add cost but give you more control over handle style, lock feel and finish.
Glass upgrades follow a similar logic. The standard 5+27A+5 tempered insulated glass works for most climates. If you need better thermal performance, ask about low-E coatings or argon-filled units. Laminated glass adds security and sound control. Triple glazing is available for the K80 French door series, but for folding doors the most common upgrade is a better insulated double-glazed unit.
Built-in blinds are another option for corner folding glass doors. Manual or electric blinds sit inside the glass cavity, which keeps them clean and reduces maintenance. This option adds cost but is popular for west-facing openings.
How to Get an Accurate Quote
To get a meaningful aluminium bifold doors price, send the following details: opening width and height, number of panels, preferred series, glass type, hardware brand, finish color and shipping destination. A rough sketch or photo helps. WANJIA Hiseng responds within 3 hours with a quote based on those details.
Remember that the quote covers the door itself. Shipping, customs and local installation are separate. WANJIA Hiseng provides installation videos and guidance after the goods arrive, and the technical team can help with measurement solutions before you order. Warranty depends on the specific product and contract terms.
If you are not ready to order a full set, sample orders are supported before bulk purchase. This lets you check the profile, finish and hardware in person before committing to a large order.
Comparing Folding Doors to Other Door Types
Aluminium bifold doors are not the only option for wide openings. Sliding patio doors use fewer moving parts and often cost less per linear foot. The 170 series lifting and sliding door is ENERGY STAR certification-backed and uses 2.2 mm frame with triple glass. French doors give a classic look with a single hinge line, and the K80 large entrance aluminum double casement door has a Uw of 1.4 W/m²K. Aluminum clad wood doors offer a wood interior with an aluminum exterior, at a higher price point than all-aluminum folding doors.
Folding doors win when you want to open most of the wall. A four-panel folding door can clear an opening that would need two or three separate sliding panels. That flexibility is why builders and architects specify folding doors for patios, kitchens and commercial storefronts.
Common Pricing Questions
Why do prices vary so much between suppliers?
Profile thickness, glass spec, hardware brand and finish quality all differ. A cheap quote often means thinner profiles, basic hardware and no thermal break. WANJIA Hiseng publishes the actual profile thickness and glass make-up for each series, so you can compare like for like.
Does the number of panels change the price per panel?
Yes. More panels mean more hardware, more glass and more assembly time. However, the cost per panel usually drops slightly as the order grows because setup and packing are spread over more units.
Are corner folding doors more expensive?
Corner folding glass doors cost more than straight runs because they need a special corner post and often two sets of hardware. The Uw range for aluminum bifold patio doors is 2.0 to 3.5 W/m²K, and corner units with built-in blinds add further cost.
Planning Your Budget
Start with the series that matches your opening size and performance needs. Then add glass and hardware upgrades only if they solve a real problem. A 68 series door with standard glass will be the most affordable. An 88 series door with low-E glass and Hoppe hardware will cost more but deliver better thermal performance and a wider choice of finishes.
WANJIA Hiseng exports to 80+ countries, with a focus on the North American market. The factory covers 322,917 sq.ft and the showroom spans 114,966 sq.ft. That scale means consistent production and the ability to handle bulk orders for dealers and builders.
