What is an SR4 security door?

An SR4 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 SR4 classification, the tested performance includes a minimum of ten minutes of effective attack time using specified tools.

Where are SR4 security doors used?

Data centres and technical infrastructure rooms, utilities, substations and plant facilities, industrial premises, secure storage and distribution sites, commercial premises with high-value equipment or assets, government or public-sector buildings and selected transport and airport projects where SR4 meets the security specification.

Can I order an SR4 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.
