They are found on workshops, warehouses, retail units and industrial sites throughout the UK and earn their keep with very few problems. When a business needs a door that is tough, secure and space-efficient, Steel Roller Doors are hard to beat.
How They Work
A roller door is made from interlocking steel slats that coil up into a cylinder above the opening. A conventional door, whether swinging out or tilting, blocks the clear space in front of and behind it. This is particularly useful in a yard with obstructed spaces and loading bays.
Why Steel?
Because of its strength, durability, and ability to take impact, steel is a good choice for areas where vehicles and equipment come and go. For areas where insulation isn’t a problem, single-skin doors are an economical option. Double-skin doors or doors with insulation are a good option for heated areas to reduce heat loss.
Security
A closed steel door presents a serious barrier. Look for an enhanced bottom rail, heavy duty locking mechanisms, and a design that prevents being forced upward. Many businesses also add an alarm or access control.
Manual or Electric?
Small doors are operated by either hand chain or pull rope. Larger doors work best with an electric motor operated by remote control, keypad or key switch. For safety, Edge sensors and obstructed sensor should be added.
Measuring Up
It is essential to determine the dimensions of the opening, as well as the required headroom and side room for the box and guides. This will ensure prompt delivery and avoidance of extra costs.
Maintenance
Clean the guides and lubricate moving parts, and have the door serviced annually. Attend to an uneven door as soon as possible. This can help avoid costly breakdowns.
Where Steel Roller Doors Work Best
Roller doors work well on industrial units, workshops, retail outlets and storage units, especially where vehicles need to get close to the opening, as nothing swings out. Roller shutters also lend themselves well to service yards and shared alleys where an outward opening door would block the passage.
Single Skin or Insulated?
A single-skin steel door is the most basic and least expensive option. It is strong and secure, but offers little to no insulation. If the unit is heated or you store temperature sensitive goods, and you want to cut heat loss and noise, you will want to choose a double-skin door with a foam/wool core insulation. Ask your supplier for info on the thermal performance of each to help make your decision.
Ventilation and Light
Some divisions require daylight and airflow when the door is closed. Options for design of panels are perforated slats, ventilated sections and vision panels. Think about whether staff will be working near the door, as extra light can make the space safer and better.
Choosing a Finish
Steel doors are galvanised or powder coated. Powder coating lets you add a colour of your choice. It also helps against corrosion. In coastal or high moisture areas, using a high-quality coating is important to maintain the look of the door.
A Practical Choice
Steel roller doors are a good choice for a number of reasons for many business premises. Compare options carefully and find a supplier who offers advice to help you choose the most suitable option for you.
