Why Regular Industrial Door Servicing Is Critical for Business Operations  Industrial doors do far more than open and close; they safeguard stock, control energy loss and protect staff. Yet they’re often ignored, until a jammed roller shutter halts production or a failed fire door breaches compliance. Proactive industrial door servicing turns these potential crises into routine, low‑cost maintenance tasks, protecting productivity and people alike. Introduction From distribution centres to food‑processing plants, industrial doors are mission‑critical. They regulate workflow, keep environments secure and help businesses meet health‑and‑safety targets. When a door fails, the ripple effects include: ● Downtime – stalled forklifts, missed dispatch slots, overtime costs ● Asset damage – warped tracks, torn curtains, dented panels ● Safety risks – trapped personnel, blocked fire‑escape routes ● Compliance exposure – insurance disputes, HSE penaltiesRegular industrial door servicing is a modest investment compared with these hidden costs. What Is Industrial Door Servicing? A professional maintenance visit typically includes: 1. Inspection – checking panels, tracks, springs, safety edges and control gear for wear or misalignment. 2. Lubrication – applying specialist greases to rollers, hinges and bearings to minimise friction. 3. Safety checks – testing photo‑cells, emergency release systems, fall‑arrest devices and fire‑door closers. 4. Replacement of worn parts – swapping cables, seals or weather strips before they fail. Doors That Require Routine Attention ● Roller shutters – heavy‑duty curtains and barrel assemblies need tension and balance checks. ● High ‑ speed doors – rapid cycles demand frequent sensor calibration and curtain inspection. ● Fire ‑ rated doors – legally mandated fire door compliance inspections verify integrity and automatic closing. ● Sectional overheads, dock levellers and steel security doors – each has unique service points that keep them running smoothly. Key Benefits of Regular Servicing Enhanced Operational Safety A well‑maintained door closes fully, detects obstructions and disengages safely in an emergency. This reduces the risk of crush injuries and ensures evacuation routes remain clear. Prevention of Unexpected Breakdowns Routine door maintenance identifies frayed cables or misaligned tracks before they snap or jam, avoiding unplanned stoppages and expensive call‑outs. Prolonged Equipment Lifespan Just as regular oil changes protect an engine, scheduled lubrication and component replacement extend a door’s working life, delaying capital expenditure on replacements. Legal Compliance Fire‑rated doors must meet BS EN 16034 standards and be inspected at least annually. Planned servicing produces a clear industrial door inspection record for auditors, insurers and the HSE.

Choosing the Right Industrial Door for Your Business

The Importance of Industrial Door Maintenance for Your Business

Reducing the risk of serious injury means setting boundaries for anyone operating your industrial overhead door and ensuring all areas are properly marked.

Tridoor has been producing high speed doors for industrial businesses for 20+ years. Our high speed doors provide both ease of access and high security.

In simple terms yes. Roller shutter doors are manufactured using individual components that make up the full door system. The main components of a roller shutter door is the barrel assembly and the door curtain, these too are made up of individual items and can be replaced but the extent of this damage or wear to these two vital parts can sometimes make replacement a more cost effective option. The roller shutter door barrel: The barrel assembly or axle is often a steel tube, the size and thickness is determined to prevent deflection of the tube under the weight of the door curtain (industry standard is 1:400). The barrel may contain shafts, bushes, springs, motor and brakes. Depending upon the age of the door, all the items are readily available and replaceable. The roller barrel assembly is a classed as a suspension element and carries the weight of the roller shutter curtain, It is recommended that any repairs to the barrel assembly is carried out by a specialist door contractor who has the expertise to identify the parts, faults and can carry out the repairs safely. Replacement of motors and safety brakes should only be carried out by a specialist door contractor 

Roller shutter maintenance depends. Legal rights say industrial doors need maintenance every year but a domestic door can last longer due to lack of use.

In the design, manufacture and maintenance of industrial doors, demands of site, users and the environment are all taken into consideration. A suitable and sufficient risk assessment should be carried out for compliance and even where state-of-the-art requirements have been achieved, residual hazards are still present. Where recital 14 of the machinery directive is concerned, state-of-the-art is not cutting edge safety but the minimum level of safety required. Automatic doors can be opened by various means ranging from a simple push button, remote control, radar or induction floor loops, which activate the door and the door will raise to its upper most position. Once the door has reached its fully open position, for a fully automatic door, usually a timer is activated and the door will count down for a pre-determined time and the door will commence to close. An automatic door can also be where the door will remain at its fully open position indefinitely and requires a signal to close. Upon receipt of this signal, the door will begin to close automatically. For a door to work automatically in the closed position, safety features need to be present to prevent the door closing onto an obstruction or person. This can be in the form of a safety edge in conjunction with a low-level safety beam where either breaking the beam or contact of the safety edge will stop and return the door to the open position. Where a light barrier is installed, this is a full light curtain grid across the door opening and in the path of the closing door to a height of approximately 2500mm; crossing this beam at any point will stop and return the closing the door. As mentioned previously, recital 14 of the Machinery Directive relates to the minimum requirements for safety therefore residual hazards can still be present. When an automatic closing door is installed or maintained, the specialist door contractor should carry out a force test of the closing door. The force of the closing door should not exceed 400n, should reduce back to 150n in 0.75s to allow the door to stop and return so no overrun is present and should reduce further to 25n within 5s. The test is carried out at specific locations beneath the door and at heights where the door reaches full speed. A special force test meter is required to measure these forces on both doors and gates and should be calibrated on an annual basis. The test is recorded and a certificate is issued in order for the door to be compliant.
