Standards and Classifications.

Created by the European Committee for Standardization, the European Standard EN 13123/124-1 and EN 13123/124-2 are internationally recognized standards used to qualify the protection provided of security structures and products (complete with fillings and locks). To receive certification, products are independently tested on sites with companies such as Comblast in highly regulated environments to provide the level of protection requested. Safetell products have also been tested to ISO 16933.

Please see the blast ratings below. Ratings are to the actual need, i.e. 5 tons/m2 of 180 milliseconds (ms) and to an equivalent of 100kg of TNT at a given distance

LPCB Accredited Door Test

We went through the rigorous testing programme for our Stalwart Steel Door and are pleased to report that it achieved a LPCB LPS1175 SR4 issue 8 rating for manual attack. This means our product can now be found here listed on The Red Book alongside other security products which offer exceptional levels of security.

Re-enhanced Petrol Forecourt Door

Not only do we sell security doors, but we can also re-enhance any commercial doors to a higher security level, withstanding attack for a much longer period, depending on specification and project requirement.
