Hunan Haolv Building Materials Co., Ltd. has 19 years experience in manufacture of high quality UPVC Balcony Door systems approved by ISO, CE and AAMA. Our developed un-plasticized polyvinyl chloride profiles are multi-chamber constructions with reinforced steel cores, delivering thermal insulation values of up to 1.3 W/m2K. We offer one-stop procurement solutions, such as customised frames, multi-point locking hardware, and double/triple glazing choices. We also partner with CONCH to ensure a consistent supply of raw materials. We have fast delivery cycles of 25-30 days and complete OEM/ODM possibilities with our balcony door systems. Our products save up to 40% energy over standard materials and dimensional correctness is within ±0.5mm tolerances.

UPVC material won’t rot, corrode or distort like wood or aluminium options. The plastic formulation developed consists of PVC resin, stabilisers and impact modifiers that make very hard structures.
UV damage protection and excellent colour uniformity is provided by Titanium Dioxide content. Your balcony doors will appear like new for decades with very little maintenance needed.
The multi-chamber profile design holds air pockets in place, forming natural temperature barriers. This lowers transmission of heating and cooling, saving you money on energy expenses year-round.

The multi-point locking systems have between 5 and 7 contact points along the door frame. When you spin the handle , all the locks engage simultaneously , spreading the force equally throughout the structure .
Hardware components are tested for 100,000+ cycles for long-term reliability verification. Toughened glass choices provide additional security for ground level installations.
Anti-lift systems prevent the window from being lifted out from the outside. Your family may rest easy knowing your UPVC Balcony Door fulfils strict security requirements.
Units double or triple glazed are available argon filled for further insulation. This invisible barrier drastically cuts down the flow of heat into and out of the interior environment.
Thermal imaging validation to guarantee no gas escape inside enclosed systems. This provides steady performance to keep the inside at a suitable temperature all year.
Reduced HVAC effort immediately correlates into cheaper utility expenditures. Many clients claim savings of 30-40% on heating and cooling costs following installation.
OEM/ODM Services We customise door sizes, hardware finishes and glass combinations to suit your project needs. Engineers provide technical guidance throughout the design process.
It is suitable for use in residential balconies, patio entrances, business offices and public building access points. It is available in both inward and outward opening versions.
Wide profile choices (80-90mm) are suited to cold climate applications that need maximum insulation. With narrow profiles (60-70mm) they provide cost efficient options for moderate situations without sacrificing on quality.

Weld strength tests are carried out on the corner to validate structural integrity according to ISO 179. Each fusion site can sustain mechanical force comparable to years of everyday use.
Spectrophotometer analysis tests for UV resistance and colour consistency across manufacturing batches. That means your UPVC Balcony Door will look as good as new for many years to come.
EN requirements for air permeability and water tightness testing assure zero leakage under high pressure settings. Products undergo examination prior to shipping.
