What is an SR3 security door?

An SR3 security door is a complete doorset tested to a defined level of resistance against forced entry under older LPS 1175 security-rating classifications. Under the applicable legacy SR3 classification, the tested performance includes a minimum of five minutes of effective attack time using specified tools.

Where are SR3 security doors used?

Commercial and industrial premises, warehouses, schools, universities and public buildings, utilities, plant and service rooms, apartments and mixed-use developments, communal or restricted-access areas, infrastructure facilities where SR3 meets the security specification.

Can I order an SR3 door supply-only?

Yes. If needed Shaw Security can quote for nationwide supply-only projects, subject to requirements.

Tell us your required door sizes, number of doors, installation location and any fire, locking or access-control requirements. Shaw Security will review the specification and advise on appropriate available doorset options.
