“Prego telheiro galvanizado” (Portuguese for “galvanized roofing nail”) is a specialized nail used in construction to fix roof tiles or sheets. Its main characteristics are:
· Galvanized Finish: Usually coated with a protective zinc layer (like electro-galvanization or hot-dip processes) to resist rust and corrosion, ensuring a long service life even in outdoor or moist environments.
· Large, Umbrella type head: Typically features an “umbrella” or wide, flat top to securely fasten roofing materials without tearing through them.
· Varied Shanks: The nail shaft can be either smooth or twisted (ring shank), with the twisted version providing a much stronger grip and better pull-out resistance.
· Typical Sizes: Common dimensions are indicated by model numbers (e.g., 18×27, 18×30, 18×36, which correspond to the wire gauge and length). The length generally ranges from about 19 mm to 102 mm (3/4 to 4 inches).
· Material: Most are manufactured from low-carbon steel grades like Q195 or Q235, which offer a good balance of strength and flexibility.
.Packing: 500g per platic bag then 50bags per carton or 1kg bag ,25bags per carton
Application:
–Fixing asbestos shingles and plastic shingles: Corrugated nails are often used in roof construction to fix asbestos shingles, plastic shingles and other roofing materials on wood structures or metal keels. To prevent water leakage, a washer is usually needed under the nail cap.
–Connecting wood components: widely used for the installation and fixation of wood products such as wooden structures, doors and windows, furniture, etc.
–Connecting iron materials: such as iron sheet, aluminum alloy, etc., because of their high hardness, can provide enough tension for corrugated nails with shallow threads to achieve stable connection.
–Fixation of decoration base: used for the connection between cement wall, ground and surface materials, and the fixation of base structure during decoration.
