Tips/hints

OUR CONSULTANT ENGINEERS ARE AVAILABLE TO HELP YOU IN THE FOLLOWING AREAS:

 

 

A. Don't delude youself : security is not a game!

 

  • Ask for a certificate before choosing the company, rather than afterwards: you will gain time and avoid futile discussions with the supplier.
  • Check that the products you have chosen are entirely covered (dimensions, glazing, fittings) by the test certificate (or Benor certification). Any certificate is only valid for doors or units of the same type and similar size (specified in the certificate), with identical fittings, installed using the same fitting methods.
  • Check that the performance levels accredited by the certificate are actually those applicable in the country where the door is being installed. In actual fact, even though there is a common test methodology in the EU, every country remains free to choose its level of security and therefore impose a particular performance level (for instance, EI1 in Belgium, EI2 in France).
  • A test certificate must be issued by an authorised European laboratory.
  • Any extension of a certificate must be approved in writing by the relevant authorities.
  • Any technical door proposed by a manufacturer is not necessarily covered by a successful, valid certificate in the country of installation.
  • A test certificate is not a certificate of manufacture. Only checks carried out by certification bodies can guarantee that the production system complies with the certificate (BENOR, NF, ISO etc).
  • The architect always shares the responsibility for the decision to purchase the selected product.
  • When a quotation request is made, comparable responses can only be produced if this request is supported by specification clauses detailing the performance features required in both the short and long term, rather than by a simple product description.

B. How do you make the most of your budget ? 

 

 

You must analyse your customer’s needs carefully.

Avoid adding features later on

 

  • Door usage: high-frequency traffic, heavy loads, use of trolleys 
  • Necessary additional performance features (acoustic, access control etc.)
     
  • Adaptation to atmospheric conditions, internal environment (kitchens, presence of chemicals, noise etc.) or external environment (maritime, high-crime area, vandalism, noise etc.)
  • Clearly define the dimensions and positions of openings: access width, light traffic, direction of doors
     
  • Integrated ventilation, suitable glazing
  • Choice of accessories required: anti-panic bar, door closer, pull handle, doorknob, storm chain (against the wind), access control etc.

 

Avoid having too many fittings

 

  • Check the consistency of the actual door’s design (e.g. high-level burglary-resistant lock with non-security glazing!)
  • Check that the door’s performance features are consistent with its environment (e.g. a burglary-resistant door on a plaster partition wall or beside a frame with non-security glazing!).
  • Make sure that the performance levels required for the doors are sufficient in relation to the company’s risk management strategy.

 

Reduce your budget

 

  • Dimensions. Can I play around with the dimensions of the doors to reduce my costs? The system for manufacturing the doors includes limit values where, if they are exceeded, this generates a significant increase in production costs. You now need to ask yourself the question: can I play around slightly with the dimensions of the doors to reduce the cost of the doors significantly?
  •  Single/double: A wider single door can beneficially replace a double door (e.g. emergency exit)
     
  • Choice of finishes. Paint or natural steel colour? Not using paint can reduce the cost of your door by up to 20%.
  • Choice of door type: a swing door can be beneficially replaced by a double-direction hung door.
     
  • Combination of performance features: a restricted passageway with 2 doors can sometimes be replaced by a single door offering multiple performance features (e.g. soundproof protection + fire resistance).

C. Providing multiple protection also means maximising your comfort at a minimum cost.

 

Long-term vision

 

  • Provide for future requirements by integrating protection features right from the moment of the building’s design. 

Example :

Nowadays, fire resistance and soundproof protection are starting to become working condition requirements. Integrating this second protection feature involves a minor marginal cost. Likewise, integrating burglary resistance will mean a worthwhile marginal cost in return for significant results.

 

Maximising space

 

  • Why not gain floor area and increase the size of a restricted passageway by combining acoustic and fire-resisting features in the same door.

D. Providing ultimate customer satisfaction

 

  • The purchase price of a door is not its total cost
  • The cost of repairing a door varies from one manufacturer to another. 

A “Meccano” type assembly system using a screw action, like Metal+ Inside, is more cost-effective than a welded assembly because it offers the option to:

 

  • adjust/replace the hinges (twist action)
  • replace the fittings 
  • replace only the door leaf
  • etc
  • Demand a warranty level from the manufacturers 

 

  • in terms of service life of the protection performance features
  • in terms of the door set’s service life (a door which can no longer be closed automatically loses its required fire-resisting, vandal-proof and soundproofing protection features)
  • in terms of maintenance cost
  • in terms of spare part availability

E. Why choose a steel door set ?

 

Benefits of steel doors

 

1) Durability


Steel is a modern material providing exceptional durability and resistance to both mechanical and dynamic stress, at a highly competitive price. Steel door sets are now very highly rated in both industrial and public buildings where they have to put up with major mechanical stress through frequent, heavy-duty use. Any damage which occurs can also be easily repaired, which is not the case for other materials. 

 

2) Eco-friendly
 

They have a long service life, are reparable and 100% recyclable, and they do not require painting (depending on the type of steel).

 

3) Fire resistance


When it comes to fire resistance, steel has valuable features to offer, notably a melting point above 1200 °C and no toxic gas emissions.
