Entrance Door Manufacturer in China | Aluminum Entry Door Specs, Price Tables and U-Values
An entrance door carries the highest load cycle and the strictest security requirement of any opening in a building. This page lists the profile data, coating parameters, test results, price bands and order terms we apply to aluminium entrance door production in Guangdong, China, so a buyer can compare quotations line by line instead of relying on marketing copy.
Entrance Door Profile and Material Specifications
Aluminium Alloy Grade and Wall Thickness
All structural profiles are extruded from 6063-T5 aluminium billet, with 6061-T6 used for pivot shafts and reinforcement inserts where higher yield strength is needed. Wall thickness is measured on the load-bearing wall, not the decorative rib.
Dimensional tolerance on cut length is ±0.5 mm, diagonal deviation on assembled leaves is held within 1.5 mm for units up to 2.6 m high and 2.0 mm above that.
Thermal Break Strip Material and Width
Thermal separation uses PA66 polyamide reinforced with 25% glass fibre, rolled into the profile channel and then knurled. Strip width is selected by climate zone rather than by price:
- 14.8 mm strip – mild climate, Uframe around 2.6 W/m²K
- 24 mm strip – standard export configuration, Uframe 2.0-2.2 W/m²K
- 34 mm strip – cold climate, Uframe 1.6-1.8 W/m²K
- 38 mm strip with foam infill – passive house range, Uframe 1.1-1.3 W/m²K
Shear strength of the rolled joint is tested per EN 14024 at 24 N/mm minimum longitudinal shear. Doors without polyamide separation (thermal foam or plastic clip only) are quoted separately because they cannot reach the same condensation resistance.
Glass and Panel Configurations
Entrance door glazing is always tempered or laminated, never annealed. Common build-ups:

Aluminum Entrance Door Production Process
Extrusion, Cutting and CNC Machining
Billet is heated to 480-520 °C and extruded at 45-55 MPa. Profiles are stretched, aged at 190-200 °C for 3 hours to reach T5 temper, then stored 24 hours before machining. Cutting is done on double-head saws at 45° or 90°, followed by CNC routing for lock cases, hinge pockets and drainage slots. Drainage slots are 5 x 25 mm minimum, staggered so that outer and inner slots are not aligned.
Powder Coating and Anodizing Parameters
Surface treatment follows a fixed parameter set that is recorded per batch:
Assembly and In-Line Quality Checks
Corner joints on entrance door leaves use CNC crimping plus two-component structural adhesive; welded corners are used only where a monolithic look is specified. Each finished leaf goes through five recorded checks: diagonal measurement, gasket continuity, hardware operation over 50 cycles, water spray at 500 Pa for 15 minutes, and glass edge inspection. Records are held per production order and shared with the buyer on request.
Main Entrance Door Configurations and Hardware
Pivot Versus Hinged Main Entrance Door
A main entrance door wider than 1.2 m on hinges will sag unless the frame is anchored into structural concrete and the hinge count is raised to four with a load rating of 160 kg each. Where the architect insists on a 1.5 m leaf, a top pivot with a concealed floor spring is the correct answer, not more hinges.
Locking Systems and Access Control
- Single-point mortise lock, 5050 or 6085 case, brass cylinder, 5 pins – baseline
- Multipoint lock: centre latch plus 2 hooks and 2 rollers, 16 mm thick faceplate
- Anti-theft grade per GB 17565: Grade B available with 8 mm steel reinforcement plate behind the lock case
- Electronic options: fingerprint, IC card, PIN, Bluetooth, Tuya or Zigbee gateway; power 6 x AA or 12 V DC with mechanical override key
- Concealed door closer, adjustable 60-120 N, for units under 150 kg
Where the priority is forced-entry resistance rather than thermal performance, review our security door specifications and pricing before finalising the hardware schedule.

Order Terms
Packing and Container Loading
Each leaf is wrapped in EPE foam 5 mm, then pearl cotton, corner protectors on all four corners, and PVC protective film on visible surfaces rated for 6 months UV exposure. Units are loaded into plywood crates of 15 mm thickness with internal battens every 400 mm. Typical loading: 60-80 sets of 900 x 2100 mm hinged doors per 40HQ; 30-40 sets of 1200 x 2700 mm pivot doors per 40HQ. Gross weight per crate is held under 900 kg for forklift handling. Glass loss rate on recorded shipments over the last 24 months is 0.4%.
Installation and Commissioning
Installation Sequence
- Verify opening dimensions and plumb; tolerance for direct frame fixing is ±5 mm, beyond that use packers and cover trim
- Set the sub-frame or fix the outer frame with M8 expansion bolts at 400-500 mm centres, minimum 150 mm from each corner
- Check frame diagonal within 2 mm before final tightening
- For pivot doors, cast or chase the floor spring box, level to ±1 mm, and grout with non-shrink mortar; allow 48 hours cure before hanging the leaf
- Hang the leaf, set reveal gap at 3-5 mm uniformly, adjust hinges or spring
- Install gaskets, threshold and drainage caps last
Waterproofing Details
Backer rod plus neutral-cure silicone on both interior and exterior perimeter, joint width 8-12 mm and depth 6-8 mm, with a 2:1 width-to-depth ratio. The exterior joint is tooled concave. Where the door sits under a balcony without an overhang, add a 20 mm drip edge and slope the sill 1:100 away from the opening. Do not use acid-cure silicone on powder-coated aluminium; it attacks the coating at the joint edge.
Adjustment and Handover Checks
Handover requires: leaf closes with a single hand under 60 N, lock engages without lifting the leaf, gasket compression visible on all four sides, water spray test at the threshold for 5 minutes with no interior wetting, and closer or floor spring set so the leaf takes 4-6 seconds to travel from 90° to latch. Hardware adjustment tools and two spare gasket lengths are shipped with every order above 20 sets.
