Gliderol light industrial series b manual steel manual roller doors

Gliderol Series B Manual Light Industrial Roller Door

Overview

The Gliderol Series B Light Industrial is a robust, manually operated continuous curtain roller door designed for commercial and industrial applications where reliability and simplicity are paramount. As a cost-effective alternative to heavy-duty industrial shutters, it offers a secure, lightweight, and easy-to-operate solution for openings up to 5 metres wide.

This model is specifically designed for manual operation, utilising a finely balanced spring-assisted mechanism or a heavy-duty chain hoist system depending on the door size.

Construction & Materials

Built to withstand the rigours of daily commercial use, the Series B features a high-quality construction specification:

• Curtain Material: Manufactured from strong 0.45mm gauge steel continuous sheet curtain.
• Finish Options: Available in a durable Plastisol colour coating (leathergrain effect) in a wide range of standard colours. A basic Galvanised Steel finish is also available for purely functional applications where colour is not required.
• Reverse Coat: The interior face of the curtain is painted with a protective two-layer grey primer coating [file:44].
• Guides: Supplied with heavy-duty 50mm wide windlock guides as standard, ensuring the curtain is held securely within the tracks even during adverse weather conditions [web:51].

Manual Operation Methods

The Series B operates smoothly thanks to its unique "spring-assisted spindle assembly," which balances the weight of the curtain for effortless movement [web:48].

• Push-Up / Pull-Down: For smaller sizes, the door can be easily operated by hand, lifting and lowering with minimal effort due to the precise spring tensioning.
• Chain Hoist (Geared): For larger doors (typically over 3000mm high or wide), a planetary geared chain hoist system is supplied [file:44]. This allows the operator to open and close the door easily from ground level using a continuous haul chain, providing mechanical advantage for heavier curtains.

Installation Requirements

This is an uninsulated steel roller door designed for Internal Face Fitting only. Please note the following critical installation details:

• Mounting: Must be fitted to the inside face of the structural opening.
• Sideroom: A minimum sideroom of 250mm is required on each side to accommodate the support brackets and guides [web:51].
• Headroom: Sufficient headroom is required to accommodate the curtain roll (drum). Larger doors will have a larger roll diameter; typically, 430mm to 550mm of headroom is recommended depending on height [web:57].
• Wind Resistance: While the door features windlock clips to secure the curtain in the guides, it is not recommended for extremely exposed locations with high wind speeds.

Suitability & Application

The Series B is an ideal choice for:

• Low to Medium Usage: Perfect for openings requiring up to approx. 20 operations per day.
• Warehouses & Units: Excellent for securing goods-in/out entrances, agricultural buildings, and workshops where thermal insulation is not a primary requirement.
• Max Dimensions: Suitable for openings up to 5000mm Wide x 4900mm High.

Note: If you require electric operation, please view our Gliderol Series B Electric Model.

The manual chain-operated Gliderol Series B is a cost-effective solution designed specifically for light industrial and low-use commercial applications. While it offers a robust physical barrier, it is vital to understand the operational limits of this continuous-curtain door to ensure it is specified for the correct environment.

Ideal Environments

The manual Series B is best suited to facilities where the door serves as a secure closure rather than a high-frequency access point. Common suitable applications include:

• Agricultural Storage: Barns and machinery sheds where the door is opened only for vehicle access at the start and end of the day.
• Dead Storage & Warehousing: Long-term storage units where access is infrequent.
• Maintenance Workshops: Secondary access points or workshops with low traffic volume.
• Large Domestic Garages: An economical solution for securing large residential openings (double/triple width) where electric operation is not required.

Critical Limitations & Suitability

1. Wind Exposure (Crucial):
The Series B features a continuous steel sheet curtain rather than individual interlocking slats. In high winds, this large surface area acts like a sail. This door is NOT suitable for exposed locations, coastal sites, or buildings positioned in wind tunnels (e.g., hilltops or open fields facing prevailing winds). Strong winds can cause the curtain to "balloon" or disengage from the guides, rendering the door inoperable.

2. Frequency of Use:
This is a Light Industrial door. It is rated for a maximum of 30 operations per day. It is not designed for busy loading bays, logistics centres, or car parks where the door is in constant use. Exceeding this cycle rate will lead to premature fatigue of the spring tensioning mechanism.

3. Operational Speed:
The manual chain hoist utilises a geared ratio (typically 4:1) to make lifting the heavy curtain manageable. While this ensures ease of use, it results in slow operation. It takes significantly longer to open a Series B manually than a standard roller shutter. It is not suitable for scenarios where rapid entry/exit is required.

Benefits of Manual Operation

Provided the limitations above are respected, the manual model offers distinct advantages:

• Independence from Power: Ideal for remote agricultural buildings or unpowered storage units.
• Minimal Maintenance: With no motor, control board, or safety sensors, the mechanical chain system is simple to maintain.
• Cost Efficiency: The most economical way to secure a large aperture up to 5 metres wide.

Installation Guidance (Manual Operation)

Comprehensive installation instructions and a safety manual are provided with every door. The following is an overview to assist with site preparation and sizing.

Critical Pre-Ordering Checks

The most common error when ordering a Gliderol Series B is misunderstanding the width measurement. Unlike sectional doors or standard roller shutters, this door overlaps the opening internally.

• The "Ordering Width" is NOT the Opening Width.
• Calculation: Measure your clear structural opening width and add 100mm (50mm overlap per side). This total is your Ordering Width.
• Ordering Height: Measure the height of the guide rails only. The curtain roll sits above this height.

Space Requirements

Manual chain-operated doors require specific clearances to accommodate the geared chain hoist mechanism and the curtain roll.

Installation Overview

The Gliderol Series B is designed for relative ease of installation, but strict adherence to the sequence is vital for safety and operation.

1. Bracket Fixing (Crucial Step): The two support brackets must be mounted to the wall/steelwork. They must be perfectly level with each other. If they are not level, the continuous curtain will "cone" (telescope) during operation, causing permanent damage.
2. Lifting the Curtain: The door is supplied as a tight roll on the axle. This heavy assembly must be lifted onto the brackets. Mechanical lifting aids (genie lift or forklift) are recommended for wider doors.
3. Chain Hoist Fitting: The geared chain drive is fitted to the axle end. The hand chain is fed through the guide and the chain retainer is mounted to the wall (approx. 1200mm from floor level).
4. Tensioning: WARNING: The internal springs are under high tension. The curtain roll is rotated to apply the necessary pre-tension before the curtain is fed into the guides. Follow the provided manual exactly for the number of turns required.
5. Guide Installation: Once tensioned, the curtain is fed into the guide channels, and the guides are fixed to the wall.

Important Safety Notes

• Spring Tension: This door utilises a powerful spring counterbalance system. Attempting to adjust or release tension without following the correct procedure can result in severe injury.
• Cutting Straps: Do NOT cut the plastic strapping holding the curtain roll until the axle is fully secured in the brackets and you are ready to feed the curtain into the guides. Cutting these too early will cause the curtain to uncoil rapidly.
• Drive-Through Height: Please remember that the bottom rail of the door will hang down approximately 80mm-100mm below the lintel even when fully open. Ensure your opening height is sufficient to accommodate this reduction.

Measuring and Ordering Guide

Important: The Gliderol Series B is designed for Internal Face Fixing only. The measurements you provide will be the manufacturing size of the door, not the size of your opening. Please follow the steps below carefully.

1. Calculating the Ordering Width

The Ordering Width for this door is the Total Width Over the Guides. To calculate this, you must measure your daylight structural opening and add an overlap for the guides.

• Measure: Measure your structural opening width in three places (top, middle, bottom).
• Select: Take the widest of these three dimensions.
• Calculate: Add 100mm to this dimension.

Formula: Widest Structural Opening + 100mm = Ordering Width

Example: If your structural opening is 4000mm wide, your Ordering Width is 4100mm.

Why add 100mm? This provides a 50mm overlap on each side, which is required to accommodate the width of the guides and the fixing lugs are an additional width requirement - see below .

2. Side Room Requirements (Clearance)

While the guides only overlap the wall by 50mm on each side, you must ensure you have sufficient physical space adjacent to the opening to accommodate the drive mechanism and mounting brackets.

• Motor/Chain Side: Requires between 150mm - 225mm clearance (depending on door height and mechanism type).
• Non-Drive Side: Requires approximately 75mm - 100mm clearance.

Motor Handling: The side of operation (Left or Right) is always chosen as viewed from inside looking out.

3. Determining the Ordering Height

The Ordering Height for the Series B is the Guide Height only. It represents the length of the side runners.

• Warning: The Ordering Height does NOT include the roller curtain roll located above the guides.
• Headroom Required: You must ensure you have sufficient headroom above the top of the guides for the door curtain to roll up into. This varies between 460mm and 530mm depending on the total height of the door.

Example: If you order a height of 3000mm, you will receive 3000mm long guides. The total space required from floor to ceiling will be 3000mm + approx. 480mm for the roll.
