The sunroom and door exhibition space keeps growing. At the 2026 Guangzhou Construction Expo, dedicated zones will show entry door expo China products and patio door and sunroom solutions for homes and commercial buildings.

The 28th China Construction Expo (Guangzhou) runs July 8–11, 2026, at the Canton Fair Complex and Poly World Trade Expo Center. The event covers about 400,000 m². Nearly 2,000 exhibitors will attend. An estimated 200,000 trade visitors from over 100 countries are expected.

Three major ecosystems debut in 2026: Indoor Space, Door & Window Outdoor, and Material & Smart Manufacturing. The Door & Window Outdoor ecosystem has expanded from four to six halls in Area D of the Canton Fair Complex. It includes sub‑zones for sunrooms, skylights, PD doors, outdoor shading, and courtyard aluminum art.

Kanod is not exhibiting. Its factory and 1,500 m² showroom are about an hour’s drive from the venue. Architects, contractors, and homeowners can schedule a private visit.

Types of Sunrooms: Aluminum, Steel Structure, and Mobile Options

Modern sunrooms are more systematized, modular, and intelligent than before. Many now come with smart sensing and automated operation.

Aluminum sunrooms are light, corrosion‑resistant, and easy to maintain. Their slim frames leave more room for glass. That works well for coastal or high‑humidity regions. Kanod’s aluminum sunrooms use thermal break technology.

Steel‑structure sunrooms handle heavier loads and larger spans. They stand up to heavy snow and high winds. That makes them a good choice for extreme climates. Steel frames get anti‑corrosion coatings and can be double‑glazed.

Mobile or retractable sunrooms use telescopic roofs and sliding glass walls. They can open completely or close fully. They work on patios, balconies, and gardens. They turn outdoor spaces into sheltered areas in minutes. At the 2026 Guangzhou Construction Expo, the expanded Door & Window Outdoor ecosystem includes a dedicated sunroom sub‑zone. That reflects growing market demand.

2026 Guangzhou Expo: Smart Sunrooms & Entry Doors

Entry Door Material Comparison: Cast Aluminum vs. Stainless Steel vs. Copper vs. Armored

Industry data puts the premium entry door market at roughly 45% cast aluminum, 25% copper, and 30% carved aluminum plate or stainless steel composite.

Cast aluminum doors resist corrosion and impact well. They allow intricate patterns. They are lighter than steel but still rigid. Salt‑spray resistance is excellent – a plus for coastal properties. Finish options include fluorocarbon spraying and heat transfer printing.

Stainless steel doors offer high strength and fire resistance. They appear often in security‑focused applications. Brushed or PVD‑coated surfaces resist fingerprints.

Copper doors are naturally antimicrobial. They develop a distinctive patina over time. Periodic sealing maintains the luster, but the aging process gives them a unique look.

Armored doors use a multi‑layer construction: steel skin, insulating core, internal reinforcement. They provide thermal and acoustic insulation while keeping a wood or metal exterior.

At this entry door expo China, visitors can see how modern entry doors integrate smart locks with biometric recognition. Kanod customizes all four material types. Finishes range from matte powder coating to hand‑applied patinas.

Smart Entry Door Trends: Facial Recognition & Remote Control

Early 2026 figures show facial recognition smart locks at 51.6% of sales. Palm vein recognition is at 16.7%. That marks a clear shift away from passwords and fingerprints toward contactless, hands‑free access.

What current smart entry doors typically include:

Facial recognition uses infrared sensors and 3D structured light cameras. The system identifies registered users and unlocks automatically. Edge computing keeps data local – no cloud transmission needed. Remote control by smartphone lets users lock or unlock from anywhere. They can issue temporary virtual keys and check real‑time status. Voice assistant integration works with Amazon Alexa and Google Assistant. Some models add multi‑modal biometric authentication – combining fingerprint, palm vein, and 3D face recognition for layered security.

The 2026 Guangzhou Construction Expo’s Smart Theme Zone covers over 40,000 m² with about 400 enterprises. It focuses on smart security, smart locks, smart lighting, smart appliances, and intelligent ventilation.

When selecting a smart door, confirm that the locking mechanism works mechanically during a power outage. Also test Wi‑Fi signal strength at the installation location before final fitting.

Installation Case and Key Considerations

A villa owner in Guangzhou wanted a combined setup. He requested a steel‑structure sunroom – about 30 m² – attached to the living room. Plus a cast aluminum smart entry door. The sunroom was installed on an existing concrete terrace.

The terrace slope needed leveling. Self‑leveling concrete kept the sunroom frame square. For heavy doors – copper or armored – check hinge reinforcements and wall framing. All joints between the sunroom and the main house were sealed with silicone and covered with aluminum flashing. For mobile sunrooms, quality tracks and 304 stainless steel silent pulleys are critical. The smart door was positioned to avoid direct afternoon sunlight on the camera lens. That reduced glare. Test facial recognition angle and smart features before final fixing. Electrical conduit went in before the final floor layer for the smart lock and LED lighting strips.

A few general reminders. Check local building codes for sunroom permits and structural requirements. In coastal or high‑wind areas, verify aluminum profile wall thickness – generally at least 2.0 mm – and wind pressure resistance grade (≥2.5 kPa). Test all smart features before final installation. Choose manufacturers with standardized processes for measuring, design, installation, and after‑sales support.

Custom Solutions from Kanod – Factory Visit Near the Guangzhou Construction Expo

Kanod is not exhibiting at the 2026 Guangzhou Construction Expo. Its factory and showroom are about an hour’s drive from the Canton Fair Complex and Poly World Trade Expo Center. Architects, contractors, and homeowners can schedule a private tour.

During a visit, you can compare four sunroom structures side by side: aluminum, steel, mobile, and hybrid designs. You can test cast aluminum, stainless steel, copper, and armored doors with different smart locking systems – including facial recognition and remote control models. You can review completed installation portfolios and discuss project‑specific climate and architectural challenges. You can also receive a no‑obligation quote and lead time estimate.

A factory visit avoids expo crowds. You get one‑on‑one time with the technical team. You can test every component by hand. You also get factory‑direct pricing – no exhibition markups.
