Technical performance description
and the structural features of the main gate
The door frame frame uses a steel structure, with steel frames welded inside the frame from steel sections and other materials.
On both sides of the main gate, HV-300B polyelaster foam corrugated panels are installed, with a total thickness of 50mm, 70rmm, and 100mm. The nominal thickness of the corrugated panel substrate is 0.5mm, and the metal mirror layer is made of aluminum and zinc, made of 55%.
Composed of aluminum, 43.5% zinc, and 1.5% silicon, the zinc content for aluminized zinc must reach 165g/m2 (double-sided), and the substrate yield strength is 345MPa. The exterior panels are coated with KYNAR500@ (KYNAR500@ containing 70% gray gas carbon metal
For color-coated steel coils, the front of the steel plate uses 5m of special gas-based ester, the topcoat is 22m of PVDF (carbon df), 600 has a medium gloss of 45-55 steel, and the back of the steel plate is a 5m modified gas-based ester
The paint is 10m polyester topcoat (PE); The color steel panels use Baosteel products; The material is guaranteed a service life of > 25 years.
The base plate of the corrugated board uses color steel plates, with a metal coating of aluminum-zinc plating, composed of 55% aluminum, 43.5% zinc, and 1.5% silicon. The aluminum-zinc coating amount must reach 150gm² (double-sided). The nominal thickness of the substrate is 0.4mm, and the substrate has strong yield strength
Degree ≥ 345MPa, color steel plates made from Baosteel products.
Polyurethane core material density≥ 48kg/m3, polyurethane core material closure rate ≥97%, combustion performance: Class B1;
The exterior decoration and edge finishing of the main door use aluminized zinc steel plates, coated with gray fluorocarbon metallic paint, with a paint film thickness of 60m and a nominal base thickness of 1.2mm.
All fasteners are designed with self-locking nuts, self-locking gaskets, or approved locking fluid or locking wire, ensuring they do not loosen due to triggering, load cycles, bending, or thermal expansion and contraction. Self-drilling screws
Strength is based on strength data released by the manufacturer. All fasteners are concealed.
The main door uses a nail-free design, with all fasteners concealed, resulting in a smooth and attractive door surface.
The contact seal between the middle door panels and the door panels uses EPDM rubber material, which has excellent weather resistance and effectively prevents cracks and breakage caused by prolonged rubber folding, ensuring the door body sealing requirements. The top of the door panel is sealed, and the door sides are tightly sealed
The seal and bottom seal should be brushed with a brush, with the brush base thickness not less than 8 millimeters. Sealing rubber and brushes are sealed and fixed onto the aluminum alloy profile, which is fixed to the outer frame of the door body.
All gates use a bottom-loading method; the floor rail bears gravity and wind loads, while the upper guide wheels and wheel slots bear wind loads.
The gate can be either electric or manual. Each gate is driven by two sets of walking mechanisms, with a transmission mechanism designed with a professional clutch. When the motor fails, the clutch is disengaged, separating the brake motor from the transmission mechanism and reducing manual operation
Manual operation is performed during the time of movement resistance. The manual control handle is integrated with the reducer and motor.
The motor head is equipped with a brake brake, allowing for precise positioning of the parking position.
The main gate is equipped with mechanical anti-collision blocks and mechanical limiting devices to prevent accidents caused by the gate being oversized.
Door guards should be installed on both sides of the main gate to prevent external impacts from damaging the door.
Drainage pipes are designed and installed on the track section at the bottom of the door body.
Each main door has a daylight window in the upper middle section, using hollow durable panels for the daylight. The panel thickness is 3.0mm, with 2.5% premium UV absorber added, and the surface is coated with Moplated® UV-resistant gel coat (thickness ≥100um).
25-year warranty; Use uniform longitudinal reinforcing ribs, mix 230% alkali-free, twist-free, and non-adhesive glass fiber, with tensile strength of no less than 120MPa and flexural strength of no less than 280MPa
Infrared sensor braking is installed on both sides of the indoor main door. When a person or object approaches within a certain range of the door, the moving gate automatically stops running. When the person or object leaves the door’s alert range, the door is reconnected
The drive mechanism should be installed on the frame inside the door leaf and have a maintenance port for easy maintenance. The drive wheels and traveling wheels use professional, high-quality load-bearing pulleys. 2. Brief usage instructions.
Run after the command. Within the first thirty seconds before the gate starts operating, the alarm bell and warning flashing light run until the gate stops operating
The gate uses variable frequency speed control, allowing for slow start and stop, smooth operation, reducing impact on the motor, and extending its service life. The core components of the control device use Siemens products.
Each door is equipped with an operation box on both sides, and each control box has three operation buttons. The three buttons are “On,” “Off,” and “Stop.” When the operator presses the corresponding movement button, the door body will perform the corresponding movement
3. Notes
The gate features a manual switch function when power is off. During a power outage, release the clutch of the geared motor, put on the handwheel, and turn the handwheel to open and close the door. Once the door is in position, be sure to close the clutch.
A maintenance port is set at the motor at the bottom of the gate to facilitate daily maintenance and servicing.
During the gate’s operation, operators must not leave the gate and must constantly observe its operating status.
The main gate track easily gets stuck in debris, so be sure to clean it regularly to ensure the gate operates normally.
Regular maintenance of the gate’s transmission components is necessary to ensure normal operation and extend the door’s service life.
