Sws seceurodoor 77 insulated three phase direct drive motor 22g steel insulated roller shutter doors

SeceuroDoor 77 Insulated Industrial Roller Shutter (Three-Phase)

The SeceuroDoor 77 Insulated is a high-quality, double-skinned steel roller shutter built to a robust 'Traditional' industrial specification. This model is powered by a powerful three-phase (415V) direct drive GfA electric motor, making it the ideal choice for medium-sized openings (up to 4m high) where reliability and performance are key.

Combining the strength of steel with advanced insulation, this door offers a significant upgrade over standard single-skin shutters. The minimal price difference is far outweighed by the benefits of thermal efficiency, acoustic reduction, and quieter operation, making it a smart investment for commercial and industrial applications.

Three-Phase Direct Drive Power

At the heart of this door is a GfA Direct Drive industrial motor. GfA motors are universally recognized as the market leader, offering cutting-edge technology and intelligent control options.

• Direct Drive Efficiency: With fewer moving parts than chain-driven systems, the direct drive motor places power directly onto the barrel. This results in simpler mechanics, reduced maintenance, and generally quieter operation.
• High-Usage Capability: Unlike standard 240V motors designed for average daily use, this 415V three-phase unit is engineered for higher duty ratings, ensuring consistent performance even in busier environments.

Insulated Curtain Construction

The curtain features a 77mm high profile slat with a 15mm depth (front to back). Each slat is filled with a CFC-free foam injected core, providing superior strength and rigidity compared to any standard single-skin profile.

• Standard Finish: Supplied in galvanised steel as standard for maximum corrosion protection.
• Colour Options: Can be powder coated in a large range of standard colours or any specific RAL colour to match your branding.

Thermal and Acoustic Benefits

The SeceuroDoor 77 combines the robustness of the popular SeceuroDoor 75 with the added advantage of insulation.

• Quieter Operation: Because the slats have a deeper profile, more weight, and sit tighter in the guides, the curtain is significantly quieter, especially in high winds where single-skin doors tend to rattle.
• Energy Efficiency: The fine-pored PU rigid foam infill and minimal thermal bridges ensure good thermal insulation (Heat transmission: 4.01 W/m²K per slat), while sealing technology reduces noise transfer from both inside and outside the building.

Comprehensive UK Manufacturing & Compliance

All SeceuroDoor products are proudly manufactured in the UK by an ISO9001 and ISO14001 certified company.

• Compliance: Fully CE or UKCA marked, ensuring total compliance with UK regulations for commercial use. (Approved LPCB security products are also available).
• Made to Measure: Every door is manufactured to your exact opening dimensions at no extra charge for a perfect fit.
• Quality Components: We use only the highest quality components and genuine GfA drives to deliver the most reliable overall package.

Warranty & Peace of Mind

Benefit from an exclusive extended 2-year warranty on the GfA industrial motor when registered using the GfA Bluetooth dongle. This smart technology allows you to track usage cycles, drive settings, and fault codes, simplifying maintenance and fleet management.

Typical use for this 77mm insulated door would be on any commercial building, office or warehouse where there were around 30 - 40 operations per day, or less. If you require higher usage please email or call us directly for the options available.

The insulated properties offer obvious benefits to many buildings to reduce energy use, but also benefit from a stronger curtain and reduced acoustic transmission to the outside and inside too.

Measuring Guide for SeceuroDoor 77 Traditional (Industrial Motor)

Understanding Ordering Dimensions

The measuring, pricing and ordering dimensions for any electric roller shutter door with an industrial electric motor drive are based on the OPENING WIDTH and GUIDE HEIGHT, excluding the guides for the width and endplates for the height. This measurement principle applies regardless of whether it is a single phase or three phase electric motor system.

Key Measurement Rules:

• OPENING WIDTH (between guides) = Ordering Width
• GUIDE HEIGHT (endplates excluded) = Ordering Height

See measuring diagram below for visual reference.

Traditional Build Installation Considerations

The Traditional build roller shutter door uses heavy-duty steel guides and steel angle profiles for installation, which can all be specified to suit different installation requirements and fixing configurations. This flexibility makes the Traditional build ideal for challenging or non-standard openings.

Overall Width at Endplate Level

The overall width at high level where the endplates are fitted will be wider than the overall guide width, and can be wider still depending on the choice of inboard or outboard motor setup.

The electric motor side with an outboard motor configuration requires more side room than the non-motor side at endplate level. Chain drive or direct drive motor choice will also vary the width required for the motor assembly.

Manual Override Access

The emergency manual override included as standard is positioned on the same side as the motor internally and is accessed directly underneath the endplate. Other positions may be available on request to suit specific site conditions.

Endplate Size Variations

The endplate size will vary depending on the door model and height, and therefore the size of the curtain roll when fully opened and rolled up. Please be aware to check the drive-through height and endplate dimensions if your headroom is critical.

Installation Methods

Face Fit - Behind the Opening (Recommended for Traditional Build Industrial Doors)

Most industrial roller shutter doors are installed to the inside face of the aperture. In a perfect scenario, your daylight opening dimensions are the space between the guides and underneath the endplate dimensions. However, it is important to note that any roller shutter will always have a 'hang down' when opened fully, making the final drive-through height slightly less than the height of the guides.

This hang down is normal and varies on different models depending on the curtain specification and roll diameter. If your opening drive-through height is critical, please speak to us first to determine the best height to order for your specific application.

Reveal Fit - Between the Opening

Some roller shutter doors are installed between the aperture opening (reveal fit), and this is where the electric tube motor roller door arrangement works particularly well, as all components are positioned inboard from the ordering dimensions.

You can install any roller shutter door between an opening, but please note that industrial motor-driven models require some additional steelwork or sub-framing to make them fit between the reveal properly and securely. The Traditional build's adaptable steel guide and angle system makes this easier to achieve than with fixed Continental-style arrangements.
