Secure, Energy-Efficient Entry Solutions for Modern Architecture
SGL's aluminium entrance doors combine 19 years of precision manufacturing experience with 6063-T5/T6 aluminum alloy extrusions to deliver entry doors that meet the structural demands of modern architecture. Produced in our 9000㎡ facility in Shaanxi, China, each door is engineered with thermal break PA66 strips to achieve a heat transfer coefficient as low as U ≤ 2.8 W/m²K, reducing energy loss by up to 40% compared to non-thermal break alternatives.
Built for both residential and commercial applications, our aluminium front doors feature multi-point locking systems with stainless steel hinges rated for 100,000+ open/close cycles. The door leaf is available with multiple internal filling options - polyurethane foam board (density ≥ 40kg/m³), rock wool board (fire rating A1), or aviation aluminum foil honeycomb - allowing you to tailor acoustic insulation (STC 30-40) and thermal performance to project specifications.
Beyond performance, we offer full customization: powder coating (300+ RAL colors), anodizing, or realistic wood grain finishes that resist UV fading for 10+ years. Whether you need a black aluminium entry door for a modern villa or a double-leaf aluminum entrance door for a commercial lobby, SGL delivers factory-direct pricing with 15-25 working day lead times. For B2B buyers, we support OEM/ODM orders, third-party certification testing, and export-ready packaging per destination standards.
How It Works - Vertical Sliding Sash Mechanism
1. Extrusion & Cutting
6063-T5/T6 billets extruded to profile, precision-cut to design specifications.
2. Surface Treatment
Powder coating or anodizing in automated line - ≥80μm thickness, salt spray tested.
3. Assembly & Filling
Frame assembly with PA66 thermal break, core filling, glazing installation.
4. Quality Inspection
Dimensional check, hardware test, air/water infiltration test per EN standards.
Key Features
1. Superior Security - Multi-Point Locking with Smart Access
- SGL entrance doors feature high-strength 6063-T5/T6 aluminum profiles with a wall thickness of 2.0-3.0mm, exceeding standard industry requirements. The multi-point locking system engages 3 to 7 locking points along the door frame. Doors support smart lock retrofitting (fingerprint, RFID, keypad, or Bluetooth APP) and are compatible with 24V electric strike systems.
2. Energy-Efficient & Soundproof - Thermal Break + Insulated Core
- Our thermal break aluminium entrance doors utilize PA66 nylon strips (24-34mm) to separate interior and exterior frames, reducing heat transfer. Combined with PU foam core (≥40kg/m³), the complete door system achieves U-values 2.0-3.2 W/m²K and sound insulation STC 30-40 dB - reducing outdoor noise by up to 65%. Compatible with green building certification (LEED, BREEAM).
3. Weather-Resistant - Tested for Extreme Climates
- SGL entrance doors pass rain penetration and air leakage testing per EN 12208 (Class 7A-9A) and EN 12207 (Class 6-8). Dual EPDM weatherstripping seals maintain elasticity from -40°C to +120°C. For coastal projects, marine-grade powder coating (salt spray test ≥1000h) and anodized finishes (Class AA15) provide corrosion resistance against salt-laden air.
How to Choose the Right Aluminium Entrance Door
Measure Your Door Opening
Measure width & height at three points each. Use the narrowest/shortest value. Provide clearances of 10-15mm per side. Professional site measurement recommended.
Select Material & Finish
Choose powder coating (300+ RAL), anodizing (AA15), or wood grain. Consider coastal areas - marine-grade coating required for salt-laden environments.
Choose Thermal Break & Glazing
For cold/hot climates, select PA66 thermal break profiles (24-34mm). Pair with double or triple glazing for optimal U-values. Compare thermally broken alloy options.
Select Hardware & Security Features
Choose multi-point lock (3-7 points) or smart lock integration. Specify heavy-duty hinges (≥150kg), threshold type, and weatherproof seals for exterior use.

FAQ
Q: Q1: Can I get an aluminium entrance door with high thermal insulation?
A: Absolutely. SGL's thermal break aluminium entrance doors achieve U-values as low as 2.0 W/m²K by combining PA66 nylon thermal break strips (24-34mm) with an insulated core. We recommend pairing the thermal break profile with polyurethane foam filling (≥40kg/m³ density) and double glazing (5+12A+5mm) for maximum insulation. This configuration can reduce heat loss by up to 40% compared to non-thermal break aluminum doors. More guidance on door insulation can be found at Energy.gov door energy guide.
Q: Q2: Are the doors suitable for coastal areas?
A: Yes. SGL recommends three corrosion protection measures for coastal installations: (1) Anodized finish (Class AA15, 15μm minimum) or marine-grade powder coating meeting ASTM B117 salt spray test for 1,000+ hours; (2) All exposed hardware in SS316 stainless steel; (3) Additional protection on door frame base contact points. Combined with dual EPDM seals, these measures ensure structural integrity in marine environments for 15+ years.
Q: Q3: Do you offer electronic lock or smart access options?
A: Yes. SGL entrance doors support: retrofit-ready multipoint lock prep accepting most aftermarket smart locks (fingerprint, RFID, keypad, Bluetooth/WiFi APP); integrated 24V electric strikes with fail-safe/fail-secure modes for access control; and PoE-powered magnetic locks with remote monitoring for commercial projects. Please confirm the lock model and voltage when ordering so we can pre-route wiring within the frame.
Q: Q4: How to measure my door opening correctly?
A: Follow these steps: (1) Measure frame opening width at top, middle, and bottom - use the narrowest measurement; (2) Measure height at left, center, and right - use the shortest measurement; (3) Provide clearances: typically 10-15mm on each side and 10-20mm on top for frame installation; (4) Specify unit (mm or inches); (5) Check floor levelness - if slope exceeds 5mm, add a custom threshold. We recommend professional on-site measurement for complex openings.
Q: Q5: What is the typical lead time?
A: Standard production lead time is 15-25 working days for stock profile colors and standard sizes. Custom RAL colors or wood grain require an additional 5-7 days. Large bulk orders (100+ units) may need 30-40 working days. Express production (10-12 days) is available with a rush surcharge. Shipping varies by mode: sea freight 15-35 days, air freight 5-7 days, express courier 3-5 days.
Q: Q6: Do you provide installation service?
A: For overseas clients: detailed installation drawings (PDF + DWG), installation video guidance, and remote technical support via video call. For domestic China projects (Shaanxi and neighboring provinces): on-site installation by our trained team. All doors are pre-assembled at the factory - the frame comes pre-drilled and the door leaf is pre-hung - minimizing on-site labor.
Q: Q7: Do SGL aluminium entrance doors have fire-rated options?
A: Yes. SGL offers fire-rated aluminium entrance doors tested to EN 1634-1 standards, achieving EI 30 to EI 60 (30-60 minute integrity and insulation). The fire-rated version uses intumescent seals, rock wool core (A1 fire rating), and specialized glazing. Please specify your required fire rating and local certification standards when ordering.
Q: Q8: What glass options are available for your aluminium entrance doors?
A: SGL offers: single tempered glass (5/6mm) for interior applications; double glazing (5+12A+5mm) for standard thermal/acoustic insulation; laminated glass (5+0.76PVB+5mm) for enhanced security; triple glazing (5+9A+5+9A+5mm) for maximum thermal performance; and Low-E coated glass that reflects infrared heat. All glass is tempered for safety and can be supplied with argon gas filling and warm edge spacer bars.
