Sws seceurodoor 75 three phase chain drive motor 20g steel steel roller shutter doors

SeceuroDoor 75 (20g) Chain Driven Industrial Shutter

The SeceuroDoor 75 (20g) Chain Drive is a robust, heavy-duty industrial roller shutter designed for larger openings and demanding commercial environments. Combining a thicker 20 gauge (20swg) galvanised steel curtain with a powerful chain-driven GfA transmission, this door offers exceptional durability and installation flexibility.

Powered by a 3-phase 415V industrial motor, this model is engineered for medium to high usage, making it the ideal solution for warehouses, factories, and agricultural buildings where reliability and structural rigidity are critical.

Heavy-Duty 20 Gauge Construction

Standard commercial shutters often utilize a lighter 22 gauge steel. This heavy-duty model upgrades the curtain to 20 gauge steel (approx. 0.9mm thick), providing significant structural advantages:

• Structural Rigidity: The thicker steel profile minimizes "slat deflection" (bowing) across wide openings, ensuring smooth operation and preventing the jamming issues often associated with lighter doors on large spans.
• Security and Durability: The 75mm scrolled steel laths offer a stronger physical barrier against intrusion and impact damage.
• Finish: Supplied in high-quality natural galvanised steel as standard (guides and endplates included), offering a tough, maintenance-free finish ideal for industrial settings.

Flexible Chain Drive System (3-Phase)

The defining feature of this model is the GfA 415V Chain Drive Motor. Unlike direct-drive systems which are rigidly mounted to the axle, the chain drive system transmits power via a heavy-duty chain and sprocket assembly. This offers distinct advantages:

• Installation Flexibility (Inboard vs. Outboard): One of the key benefits of the chain drive is adaptability. Depending on the space available at your site, the motor can often be mounted Inboard (inside the endplate dimensions to save side room) or Outboard (standard configuration for easier maintenance access).
• Mechanical Advantage: The gearing provided by the chain drive system delivers high torque, allowing the door to lift heavy 20-gauge curtains with ease.
• Manual Override: In the event of a power failure, the chain drive system includes a haul-chain manual override, allowing the door to be opened or closed by hand from floor level.

Usage and Suitability

This door is designed for a Traditional Internal Face Fit, typically mounting behind the structural opening on steel or masonry.

• Power Supply: Requires a 3-Phase 415V industrial power supply (neutral and earth required).
• Frequency: The industrial GfA motor is rated for frequent daily use, far exceeding the duty cycles of standard single-phase tube motors.
• Size Capacity: The combination of the 20-gauge curtain and heavy-duty motor allows this door to cover large industrial apertures where standard doors would fail.

Construction Specification

The SeceuroDoor 75 (20g) is a heavy-duty industrial roller shutter designed for longevity and security. It utilises a traditional commercial build specification but upgrades the curtain material for enhanced performance.

• Curtain Material: 20 Gauge (approx. 0.9mm) Galvanised Steel.
• Profile: 75mm traditional curved steel lath.
• Durability: The use of 20 gauge steel provides superior resistance to deflection and wind loading compared to standard commercial doors.
• Finish: Natural Galvanised Steel (Standard).

The Power Unit: GfA Elektromaten Drive

The heart of this roller shutter is the motor. We do not compromise on this critical component, powering this door with a GfA 3-Phase (415V) Chain Drive Electric Motor. Widely recognised as the global market leader in industrial door automation, GfA (German engineering) motors offer unmatched reliability.

• Precision Engineering: GfA motors are renowned for their robust gearboxes and precision manufacturing, ensuring smooth, consistent operation even under heavy daily usage.
• Digital Limits: Unlike older mechanical limit switches which can drift over time, GfA motors utilise absolute encoders (digital limits) for pinpoint stopping accuracy every time.
• Chain Transmission: The chain drive mechanism provides immense torque for lifting heavy 20-gauge curtains and allows for flexible motor positioning (Inboard/Outboard).
• Manual Override: Includes an integrated hand-chain system, allowing full manual operation of the door from floor level during power outages.

Control Logic and Operation

We offer three distinct control tiers to suit your operational needs and budget, all utilizing the GfA control hardware:

1. Hold-to-Run (Basic / 'Deadman')

The most cost-effective option for simple industrial applications.

• Operation: The user must press and physically hold the button on the internal wall station for the entire duration of the cycle.
• Safety: Because the operator is present and observing the door, additional safety sensors are not legally required.
• Constraint: You cannot operate this door from the outside; a separate pedestrian entrance is required.

2. Impulse Operation (Standard Automatic)

A "one-touch" system designed for convenience and efficiency.

• Operation: A single momentary press of the 'Up' or 'Down' button is all that is required to fully open or close the door.
• Safety Compliance: To meet UK regulations for automated doors, this system includes a Safety Edge on the bottom rail. This sensor detects impact and instantly reverses the door if an obstruction is met.

3. Remote Control (Advanced)

The premium option for logistics and vehicle access.

• Operation: Includes the features of Impulse operation but adds radio control capability (supplied with 2 handsets as standard).
• Safety Compliance: Includes the mandatory Safety Edge system.
• Recommendation: For doors facing public highways or high-traffic areas, we strongly recommend adding Infra-Red Photocells as a secondary safety layer.

Finish and Colour Options

The door is supplied in Natural Galvanised Steel as standard—a popular, rugged look for industrial sites. However, aesthetic upgrades are available:

• Powdercoat Finish: A polyester powder paint applied to both sides of the curtain slats. Ideal for retail or areas where internal presentation is key.
• Plastisol Finish: A high-performance leather-grain coating applied to the external face only (internal face is standard primer). Offers excellent weather resistance.

Bespoke colours and mixed-finish configurations (e.g., painted curtain with galvanised guides) are available upon request.

Measuring and Ordering Guide

Important: Unlike domestic roller doors, the pricing and ordering dimensions for industrial electric shutter doors are based on the Opening Width (Daylight Opening) and the Guide Height. Please read the definitions below carefully.

Ordering Width = The Daylight Opening Width (The clear distance between the guides)
Ordering Height = The Guide Height (The distance from the floor to the underside of the endplate)

1. Understanding Widths and Side Room

While the Ordering Width is measured between the guides, you must ensure you have sufficient side room for the operation mechanism at high level. The overall width at the top of the door (where the endplates and motor are fitted) will be wider than the guide width.

• Endplate Width: The mechanism extends past the guides on both sides.
• Motor Arrangement: The total width depends on whether you choose an Inboard or Outboard motor setup.
• Drive Side Clearance: An outboard electric motor requires significantly more side room than the non-motor side. This varies depending on whether a chain drive or direct drive motor is specified.
• Manual Override: The emergency manual override is standardly located on the same side as the motor, accessed directly underneath the endplate. (Alternative positions available on request).

2. Headroom and Endplates

The size of the endplates (and therefore the headroom required) is not fixed; it varies depending on the specific door model and the total height of the door. Taller doors require a larger roll of curtain, which necessitates larger endplates.

Installation Methods

Traditional build roller shutter doors use steel guides and angle profiles. These can be specified to suit different fixing locations.

Face Fit - Behind the Opening (Recommended)

This is the standard installation method for traditional industrial doors. The guides are fixed to the inside face of the wall.

• Sizing: In a perfect scenario, your Daylight Opening dimensions equal your Ordering Width (between guides) and Ordering Height (under endplate).
• Hangdown Warning: Please be aware that ALL roller shutters have a degree of 'hangdown' (the bottom slat remains visible in the opening) even when fully open. This makes the final drive-through height slightly lower than the Guide Height.
• Critical Heights: If your drive-through height is critical, please speak to us first so we can advise on the best Ordering Height to ensure full clearance.

Reveal Fit - Between the Opening

It is possible to install these doors between the structural opening (within the reveal), although this is generally better suited to tube motor doors where components are contained within the barrel.

• Challenges: Industrial motor-driven models have bulky motors and components at the ends. To fit these between an opening, additional steel work/angles are usually required to create a sub-frame.
• Width Reduction: Installing between the opening will significantly reduce your drive-through width due to the guides and motor mechanism taking up space within the aperture.
