FAQs
Engineered for Endurance
World Class Technology, Global Delivery
Here you will find a range of questions that will hopefully help to answer any queries you may have regarding Hart Doors, our products and services.
A: Not all high-speed doors are suitable for external application due to varying wind pressures in exposed locations. For these applications, it is important to get a door fit for the job. Our Speedor Storm is designed with this in mind to class 5 wind resistance.
A: Reducing energy usage is not only vital for the environment, but it can directly benefit your business and your supply chain by reducing costs. A well-insulated and low-maintenance high-speed automatic door can reduce energy consumption by minimising draughts, maintaining internal temperatures, and optimising traffic flow through their high-speed automatic operation.
A: The expected life of our high-speed doors is over 20 years and 500,000 cycles in normal conditions. Having recently replaced a door after 34 years we can attest to the quality of our engineering. Fault rates are low, and when repairs are required, first time fixes are high. Due to the longevity of our doors, the total cost of ownership is low.
A: Apart from the quality manufacturing to ISO 9001: 2015 and material audit trail guaranteeing the quality of the components, we can also offer faster delivery times, spare part availability, manuals in English and superior aftercare that you can’t get from products manufactured elsewhere.

A: Generally, for roller shutters and Speedor Storms you are required to provide a 415 volt 16 amp, 3 phase neutral and earth 5 pin industrial surface mounting socket (red), conforming to EN 60309, within 1 meter of the control panel position. On doors up to 5m x 5m, it may be possible to utilise a 230 volt, single-phase supply. For Speedor Mini, a 230 volt 16 amp, 2 pin plus earth industrial surface mounting socket (Blue), conforming to EN 60309 (typically MK 9201 BLU), within 1 meter of the motor side of the door at approx. 1.5m from floor level is required. These must be available at the installation stage. This is a general guide, please consult us for the correct requirements for your purchase and international orders.
A: The preparation of the supporting structure of the fire shutters must be constructed to a strict set of rules. Brickwork, and blockwork with concrete lintels in the case of 240-minute fire resistant shutters, fully encapsulated insulated and fire-protected steel for 120-minute fire-resistant shutters and 60-minute fire boarded timber or metal stud partitioning in the case of 60-minute fire shutters. Please consult us for further guidance.
Questions you may ask before ordering a door
A: No, if you need a new or replacement door, we will send a technical sales engineer to survey your site free of charge, they will then advise the best solution for your application.

We use a 2mm twin-layer fabric for most of our high-speed doors. They are available in yellow, blue, red, green or grey fabric. For a lightweight internal door, we can use a 900g fabric available in white, grey, red and blue. See our datasheet or request a sample.
Roller shutters come in galvanised steel as standard. However, you have the option to powder coat the curtain, guides and bottom rail in any standard RAL colour.
