The majority of BDN self-drilling screws<\/a> are designed for either metal roofing or wall cladding installations, with the exception of proprietary designs for specific purposes such as PolyXpand\u2122<\/a> for plastic skylight fixings, or TRUSS-Tite\u2122<\/a> for joining truss components on steel framing.<\/p>\n

 <\/p>\n

Common issues we see on high quality, expensive metal roofing sheets fixings are:<\/strong><\/h2>\n
    \n
  1. Incorrect selection of screws, with issues ranging from length, drilling capacity, thread type, gasket, and more.<\/li>\n
  2. Poor quality screws which are unfit for the location and environment installed in.<\/li>\n
  3. Improper screws for metal roof installation<\/strong> \u2013 the majority of issues stem from insufficient knowledge of the product, not following installation guides and instructions, and most of all, carelessness. Don\u2019t forget that choosing the correct tool for the job also plays an important part in proper installation.<\/li>\n<\/ol>\n

     <\/p>\n

    \"How<\/p>\n

     <\/p>\n

    Before any installation, understand the type of structure, material, and environment we are dealing with. Since we are talking about screws for metal roof installation, determining the type of metal roof will be first priority.<\/strong><\/h2>\n

     <\/p>\n

      \n
    1. Is it a single sheet insulated panel?<\/li>\n
    2. Are there any skylight panels installed in between sheets, and if so, what type of material are the skylights?<\/li>\n
    3. What is the thickness of the sheet, and how thick is the insulated portion underneath?<\/li>\n
    4. Color of the sheet and should the screws have to come with matching head colors?<\/li>\n<\/ol>\n

       <\/p>\n

      Upon determining the type of sheet used, we then have to understand the type of structure it is affixed to.<\/strong><\/h2>\n
        \n
      1. Are the purlins steel or timber?<\/li>\n
      2. Thickness of the steel purlins?<\/li>\n
      3. Are there any trusses involved?<\/li>\n<\/ol>\n

         <\/p>\n

        We should then determine the kind of environment the building structure is built on. \u00a0Here at BDN Fasteners<\/a>, we have categorized the kind of environments to the following based on its characteristics.\u00a0 Scope of warranty for our products are also based on the category the environment is classified to.<\/p>\n
