Sws seceurodoor 75c chain operated 22g steel manual roller doors

SeceuroDoor 75C Manual Chain Operated Roller Shutter

The UK's Best Value Industrial Door Solution

The SeceuroDoor 75C is widely recognised as the most cost-effective and reliable solution for securing openings up to 5m wide x 5m high. By combining a robust traditional build with a simple manual chain drive, this model offers the lowest price point for closing off large apertures while providing a fully compliant, CE-marked industrial door system.

For businesses where power is unavailable or where the door is only operated infrequently (e.g., storage units, agricultural barns, or rear warehouse exits), the 75C delivers exceptional performance without the expense of electric motors and control panels.

Traditional Build Quality

Unlike lighter alternatives, the SeceuroDoor 75C retains a full Traditional Build specification. This means it uses heavy-duty steel angles and channel guides rather than lightweight aluminium, ensuring superior structural rigidity and longevity in commercial environments.

Designed primarily for Internal Face Fitting, this door is perfectly suited for installation onto steel-fabricated buildings, as well as brick, block, or timber structures. The "face fit" method maximizes the clear drive-through width and height, keeping the guides and coil tucked safely behind the opening.

Simple, Reliable Operation

The manual chain hoist system is geared to make lifting even larger curtains manageable and safe.

• Geared Chain Drive: A continuous haul chain operates through a geared assembly, significantly reducing the physical effort required to lift the steel curtain.
• Low Maintenance: With no electric motor, sensors, or wiring to maintain, the 75C is incredibly low-maintenance, making it a "fit and forget" solution for remote or unpowered sites.
• Security: The chain can be secured internally using a chain keep (cleat), preventing unauthorised operation from ground level.

Customisation & Finishes

While this is a value-focused door, there is no compromise on aesthetics. The strong single-skin galvanised steel curtain (available in 20g or 22g gauges) can be finished to match your brand:

• Galvanised Steel (Standard): The most economical option, providing a clean, industrial look with excellent corrosion resistance.
• Powder Coating: Available in almost any RAL or BS colour to match existing cladding or corporate colours.
• Plastisol: A durable, weather-resistant leathergrain coating available in a range of standard colours.

Key Features Summary

• Best Value: The most economical compliant industrial door for sizes up to 25m².
• Max Dimensions: Spans widths and heights up to 5000mm.
• Application: Ideal for low-usage commercial, industrial, and agricultural settings.
• Operation: Manual chain hoist (geared) for ease of use.
• Spring & Lock Option: (Available for smaller doors under 2.8m high) A simple "push-up" operation is also available if preferred.
• Made to Measure: Manufactured to the millimetre for a perfect fit every time.

Typical use would be on any standard size UK farm building, workshop or factory warehouse which isn’t accessed very often and has another method of entry to enable access to the internal chain and hoisting mechanism.

• Indirect, special or consequential loss or damage howsoever caused, including remedial work costs, call-out fees, tool or plant hire and transport costs

Important Warranty Conditions

The SeceuroDoor warranty covers parts only and does not cover labour costs or consequential costs. This includes but is not limited to call-out fees, transport costs and costs for remedial work for removing and/or re-installing faulty parts. All warranty claims must be reported promptly to allow for timely assessment and resolution.

Product Care Requirements

To maintain warranty validity and prolong the life of your SeceuroDoor product, correct operation and care in accordance with the official Operating & Maintenance Manual is essential. Regular maintenance includes wiping with a damp cloth and mild detergent to remove excessive dirt and grime, ensuring the floor is kept smooth, level and clear of dirt and debris which can damage the rubber seal, and conducting visual inspections to identify any issues before they develop into major problems.

Coastal Installation Requirements

Products installed in coastal environments or high-corrosion areas require enhanced maintenance protocols. Regular cleaning of products in locations within 2 miles of the sea is especially important. Doors should be cleaned thoroughly weekly using warm water and mild detergent with a soft cloth or sponge, allowed to dry naturally. Never use strong detergent, abrasive, caustic or solvent-based cleaners as these will void the warranty.

Visual Quality Assessment Standards

We recommend performing a visual quality check on installation. Carry out the quality check in natural daylight, not direct sunlight. Stand at a distance of 3 metres from the product to view the overall appearance. The product is acceptable if, taking into account the manufacturing process, none of the following is readily visible on the face of the product: marks or distortions associated with the manufacturing process, minor indentations, marks or scuffs on the surface, or paint or stain blemishes.

Measuring Guide: Manual Industrial Roller Shutters

The measuring, pricing, and ordering dimensions for any manual industrial roller shutter door are defined by the OPENING WIDTH and GUIDE HEIGHT. These dimensions exclude the guides for the width and the endplates for the height. Please refer to the measuring diagram below.

ORDERING WIDTH = Opening Width (Clear width between the guides)
ORDERING HEIGHT = Guide Height (Floor to top of guides, excluding endplates)

Critical Dimensions & Sideroom

The overall width at the high level (where the barrel and endplates are fitted) will be wider than the overall width across the guides. This additional width is required to accommodate the chain hoist mechanism.

• Chain Hoist Side: The side featuring the manual chain hoist requires more sideroom than the non-geared side to allow for the gear assembly and hand chain operation.
• Endplate Level: Ensure you check the specific endplate dimensions for your door size, as these extend beyond the guide width.

Endplates & Headroom

The size of the endplates (and hood, if fitted) will vary depending on the specific door model and the total height of the door, as taller doors create a larger curtain roll. Please ensure you have sufficient headroom above the ordering height to accommodate this.

• Operation Access: The hand chain is located directly underneath the endplate on the geared side. Ensure there is clear access for the operator to stand and use the chain safely.

Face Fit - Behind the Opening (Recommended)

Most manual industrial roller shutter doors are installed to the inside face of the aperture. This "Face Fit" is the standard method for Traditional build industrial doors.

In a perfect scenario, your ordering dimensions (Daylight Opening) will be equal to the space between the guides and underneath the endplates.

Important Note on Hangdown: Be aware that ANY roller shutter will have a degree of ‘hangdown’ (the bottom slat visible in the opening) when fully raised. This means the final drive-through height will be slightly less than the Guide Height. This varies by model and curtain specification. If your drive-through height is critical, please speak to us first to determine the best height to order.

Reveal Fit - Between the Opening

It is possible to install manual roller shutters between the aperture (Reveal Fit), but this often requires additional steelwork or packing to accommodate the endplates and gear assembly properly. Unlike a Face Fit, the guides and mechanism will reduce the clear drive-through width.
