Fire and Smoke ratings.
The performance of hospital fire doors is vital to any doorset.

Fire rating overview.
Fire door performance is one of the most important aspects of any doorset. There is a legal requirement for manufacturers of fire doors to provide proof of the ability of their products to resist the passage of fire through the provision of test evidence. To this end, SDS are part of the BM Trada ’Q-Mark Fire Door Manufacture Scheme’, and have carried out multiple fire test under this scheme to ensure that our fire doors meet all legal requirements. We also have a commitment to carrying out ongoing fire tests in the future—not only to ensure ongoing compliance, but also to further expand the parameters of our fire certification portfolio.
