What SR Door Ratings Mean

If you own a business, the type of doors securing the premises can protect both your property and employees working in the building. Security doors are rated depending on how they’re made, what they are made from, and their purpose. This information can help you select security doors for your business by explaining what the door ratings mean.

Who Sets the Ratings?

Ratings for security products such as windows, doors, and shutters are set by an independent organisation known as the BRE or Building Research Establishment. The standards for testing security doors, windows, or shutters are set by the Loss Prevention Certification Board, which is part of the BRE.

Security Door Ratings

When you’re selecting security doors for a new construction project or to replace doors during remodelling, you will notice that they all have SR ratings or certifications. This rating is given to a product during testing to see how resistant to intruders it is. Security door ratings will also determine what type of structure they should be installed on.

The ratings for security doors range from SR1 to SR6 depending on the company with SR6 being the most secure door. The door ratings are:

SR1

SR1 doors are generally made from single leaf, a leaf-and-a-half, or double leaf. They are made from steel and open outwardly and they are hung on steel hinges. They can either have a single lock or can be locked at multiple points and are made primarily for leisure facilities, retail stores, and other commercial buildings.

SR2

The construction is similar to the SR1 but they often have a vision panel inserted into them when it is important to see out before opening the door. These doors are installed at schools, universities, retail stores, and communal rooms at housing associations.

SR3

Depending on the manufacturer, they may have more than one SR3-rated door model. Most SR3 security doors are available in leaf, leaf-and-a-half, and double leaf doors with a single or multiple locking points and a vision panel is optional. Some SR3 doors may be fire-rated for up to four hours, meaning that they can hold a fire at bay for that many hours. They are installed at banks, police stations, hospitals, and utility buildings.

SR4

SR4-rated security doors are made from high-security steel with several locking options. They may also have panic exit, emergency escape, and personal access options installed. Vision panels or ventilated panels may also be installed in them depending on where the door is being used. They are designed for schools, retail outlets, and leisure facilities.

SR5

These security doors are similar to the SR4 in construction but they have both vision panels and ventilation panels built into them. They are made for use in high-value retail operations, utility buildings, communal areas, and police stations.

SR6

SR6 doors have single-point locking systems and they are usually installed in high-value retail operations, banks, police stations, and strategic utility buildings.

The retailer from which you purchase doors will help select the best doors for your needs.
