Wide Heavy Doors

Ted Ferris Member


Hey WoodWeb,

We have a project that calls for 40+ inch wide cabinet doors that are quite heavy (5 lbs/sq ft). Does anyone have experience with projects like this?

What type of hinges did you utilize?

Did you have issues with sagging or warping?

Any information would be very helpful.

Assumed to be 'cabinet' doors, not passage doors or similar.

If the above is a correct assumption, then the next assumption is hinge type - cup, or Euro type hinges. If my assumptions are correct so far, then you can go to any of the vendor websites to find out weight and hinge placement as well as count for the hinges.

How tall are they?

They are cabinet doors not passage doors.

We typically use euro hinges and would prefer to in this instance as well if possible

There are only a few doors the one of note is 42" W x 48" H

Thanks for any input

I seem to remember a rating on the Salice thick door euro hinges at 20lbs per hinge. That'd put you a bit under with 4 hinges for euro.

That is a good idea unfortunatley these doors are only 5/8" thick. So the salice thick door hinges will not work in this application.

How do you plan on keeping them flat? That's a ton of material hanging out there, and made worse with the 5/8" thickness.

Hello all,

This is a recipe for disaster. Although wider doors can be used with special hinge spacing, 600mm is the widest door specified by all European hinge companies.

I would go back to the designer and come up with another plan. As mentioned above, keeping a door with these dimensions flat will be another issue.

Iím curious. What is the intended use of these cabinets? Kitchen? Closet? Furniture?

Best of luck

By the way, all Salice hinges are rated at 20lbs, not just our thick door hinge.

Hey All,

These doors have 5/8" melamine backs that are clad in 16 ga steel. The cabinets will be used for storage of AV equipment adjacent to a fireplace

As long as the melamine is not suspect I wouldnt be concerned about warping and even at the weight your talking, with Dennis' response I'd say your fine with the appropriate number of hinges.

Checked back wondering what the door material was to have that weight for such a thin door.

    FORUM GUIDELINES: Please review the guidelines below before posting at WOODWEB's Interactive Message Boards (return to top)

  • WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
  • Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
  • A valid email return address must be included with each message.
  • Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
  • Subject lines may be edited for length and clarity.
  • "Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
  • Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
  • Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
  • Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
  • Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
