What are the facts about security classifications that some people recently have been raising, others lowering, some claiming to be the only ones to offer them, and others claiming whatever suits them, while others say nothing at all? Of course there are certifications and classes, and naturally those who manufacture security doors should know and apply international standards(e.g. ENV 1627- EN 1522- FB6-FB7).
It’s true that abiding by the rules and using authentic materials means the cost goes up, and that is where door and lock resistance is compromised. What is even more true, as noted in recent years, is that a large proportion of security door manufacturers take advantage of customers’ ignorance and invent non-existent certifications and classes.
Methods used to break into homes and businesses are constantly changing and no certification can protect consumers if the following are ignored:
Security doors: metal thickness and distribution-welding method.
Lock: how it is secured onto the door, how reliable it is against both old and new burglary methods.
Proper dimensions: construction of door (height-width) to the size of the opening in the wall.
Installation: specialized and controlled work crews-mounting methods.

To ensure all of the above, it is important to select a reliable company that closely monitors developments in the field, manufactures products to high-security specifications and delivers on its promises.

At SIAMO, we know, we respect and we apply the standards and add more to security and locks because that is we specialize in.
At SIAMO, we started in 1980 gradually introducing six different security models (later called classes). These were codified and included a break-down of technical specifications. They were also subject to continuous improvements in security features using cutting-edge, high security locks. Classes provide minimum limits, never maximum.
For your information, up until July 2013, there was no accredited institute or university in Greece that issued certificates or provided certification of burglary resistance classes for security doors. In addition, to our knowledge, the Greek Ministry of Public Safety is not competent to issue any anti-burglary or resistance class certificates, as some claim.

There is also a difference between ISO standards, classes, materials resistance testing departments and competence to issue class certificates.
It is important to understand that institutes only certify the sample provided to them by applicants for testing and certification. After that, it is up to the manufacturer to comply with the specifications on the tested product.
No institute prohibited increased security in keeping up with the times or the application of high security locks which are constantly advancing.

At SIAMO, we manufacture doors that far exceed the nominal resistance classes, and always offer you the opportunity to see the interior of your door while it is being made at the
