consist of three layers, featuring metal sheets on both sides and polyurethane (urethane) insulation and foam in between, ensuring resistance to heat and fire. Roof sandwich panel sheets are available in a variety of thicknesses and can be made in three different models: double-sided galvanized steel\/Aluzinc\/aluminum sheet, an internal single-sided galvanized steel\/Aluzinc\/aluminum sheet with an internal layer of aluminum foil, and a combination of galvanized and Aluzinc sheets. The trapezoidal design of the ribs in roof panels results in the overlapping of the two layers of sheets positioned above and below the panel, which prevents water leakage from the roof. The installation of roof panels entails laying the gutters and then covering them with the roofing materials. Finally, flashing sheets are used to finish the project. Roof sandwich panels are typically manufactured and installed with thicknesses ranging from 3 to 10 cm. This panel is utilized in the roofing of contemporary metal structures, including sheds, factories, halls, and roofed parking areas. Roof sandwich panels are designed and manufactured to ensure that they overlap effectively. Sandwich panels measure 1.07 cm in width, offering a useful width of 1 meter. These sandwich panels come in a variety of designs and colors, allowing you to select according to your preferences.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/section><section class=\"l-section wpb_row us_custom_432d3f53 height_medium\"><div class=\"l-section-h i-cf\"><div class=\"g-cols vc_row via_grid cols_2 laptops-cols_inherit tablets-cols_inherit mobiles-cols_1 valign_top type_default stacking_default\"><div class=\"wpb_column vc_column_container\"><div class=\"vc_column-inner\"><div class=\"w-image align_none\"><div class=\"w-image-h\"><img loading=\"lazy\" decoding=\"async\" width=\"441\" height=\"348\" src=\"https:\/\/borjpooshesh.com\/wp-content\/uploads\/2025\/01\/13654684.png\" class=\"attachment-large size-large\" alt=\"\" srcset=\"https:\/\/borjpooshesh.com\/wp-content\/uploads\/2025\/01\/13654684.png 441w, https:\/\/borjpooshesh.com\/wp-content\/uploads\/2025\/01\/13654684-300x237.png 300w\" sizes=\"auto, (max-width: 441px) 100vw, 441px\" \/><\/div><\/div><\/div><\/div><div class=\"wpb_column vc_column_container\"><div class=\"vc_column-inner\"><div class=\"w-image align_none\"><div class=\"w-image-h\"><img loading=\"lazy\" decoding=\"async\" width=\"850\" height=\"487\" src=\"https:\/\/borjpooshesh.com\/wp-content\/uploads\/2025\/07\/unnamed-1-1.jpg\" class=\"attachment-large size-large\" alt=\"\" srcset=\"https:\/\/borjpooshesh.com\/wp-content\/uploads\/2025\/07\/unnamed-1-1.jpg 850w, https:\/\/borjpooshesh.com\/wp-content\/uploads\/2025\/07\/unnamed-1-1-300x172.jpg 300w\" sizes=\"auto, (max-width: 850px) 100vw, 850px\" \/><\/div><\/div><\/div><\/div><\/div><\/div><\/section><section class=\"l-section wpb_row height_small\"><div class=\"l-section-h i-cf\"><div class=\"g-cols vc_row via_grid cols_1 laptops-cols_inherit tablets-cols_inherit mobiles-cols_1 valign_top type_default stacking_default\"><div class=\"wpb_column vc_column_container\"><div class=\"vc_column-inner\"><div class=\"wpb_text_column us_custom_432d3f53\"><div class=\"wpb_wrapper\"><h2><b>Double-Sided Galvanized Roof Sandwich Panel:<\/b><\/h2>\n<p>The procedure for manufacturing sandwich panels on the factory production line:<\/p>\n<p>&nbsp;<\/p>\n<h3><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-10332\" src=\"https:\/\/borjpooshesh.com\/wp-content\/uploads\/2024\/12\/4-4-6.webp\" alt=\"\" width=\"1024\" height=\"576\" srcset=\"https:\/\/borjpooshesh.com\/wp-content\/uploads\/2024\/12\/4-4-6.webp 1024w, https:\/\/borjpooshesh.com\/wp-content\/uploads\/2024\/12\/4-4-6-300x169.webp 300w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/h3>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">De-chlorination unit<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Heat halo unit<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Roll forming unit<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Mineral-wool board feeding system\u00a0\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">PUR\/PIR foaming system<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Double-belt pressing unit<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Cutting unit\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Cooling unit<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Product preparation unit<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Packaging unit<\/span><\/li>\n<\/ol>\n<h3><span style=\"font-weight: 400;\">\u00a0<\/span><b>Sizes of Roof Sandwich Panels :<\/b><\/h3>\n<p>&nbsp;<\/p>\n<h3><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-10491\" src=\"https:\/\/borjpooshesh.com\/wp-content\/uploads\/2025\/01\/Globe-Roof-EI.png\" alt=\"\u0627\u0646\u062f\u0627\u0632\u0647 \u0633\u0627\u0646\u062f\u0648\u06cc\u0686 \u067e\u0627\u0646\u0644 \u0633\u0642\u0641\u06cc\" width=\"1600\" height=\"418\" srcset=\"https:\/\/borjpooshesh.com\/wp-content\/uploads\/2025\/01\/Globe-Roof-EI.png 1600w, https:\/\/borjpooshesh.com\/wp-content\/uploads\/2025\/01\/Globe-Roof-EI-300x78.png 300w, https:\/\/borjpooshesh.com\/wp-content\/uploads\/2025\/01\/Globe-Roof-EI-1024x268.png 1024w\" sizes=\"auto, (max-width: 1600px) 100vw, 1600px\" \/><\/h3>\n<p><b>Components of Double-Sided Galvanized Roof Sandwich Panels:<\/b><\/p>\n<p><b>\u2714<\/b><b> Polyurethane insulating foam:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The insulating foam is the most crucial component of double-sided galvanized roof sandwich panels. This product is manufactured using polyurethane insulating foam composed of isocyanate as the primary component and polyol serving as an additive. In the relevant device, these two materials are mixed under pressure and heat, causing their volume to increase rapidly by 20 to 30 times within a few seconds, resulting in a compact, cohesive, and integrated foam of the desired thickness. Polyurethane insulating foam is the most common type of foam globally, recognized for its exceptional resistance, outstanding adhesion, and tensile strength, as well as its effectiveness in insulating against corrosion, heat, cold, and sound, all while being lightweight.<\/span><\/p>\n<h3><\/h3>\n<p><b>\u2714<\/b><b> Galvanized Sheet:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Steel is a crucial construction and engineering material globally, due to its remarkable properties, including high ductility, durability, and impressive yield and tensile strength. The vulnerability of steel lies in its response to moisture. Various methods have been developed to protect steel from corrosion caused by moisture. One approach involves applying a layer of zinc metal. Steel coated with zinc metal is referred to as galvanized steel. The coating of steel with zinc is performed through electrochemical contact, utilizing a zinc anode and an iron cathode. Therefore, if the zinc coating is compromised, the iron remains safeguarded against corrosion and rusting of the underlying metal. Zinc-coated galvanized sheets featuring a zinc layer ranging within 100\u2013275 g\/m<\/span><span style=\"font-weight: 400;\">2<\/span><span style=\"font-weight: 400;\"> are manufactured through the hot-dip process on highly automated continuous lines known as coil coating. Once the coil is uncoiled, both the lower and upper surfaces undergo a cleaning process using specialized chemicals, followed by a pre-treatment that boosts corrosion resistance and improves paint adhesion. Then, a layer of primer is generously spread across both surfaces, setting the stage for a flawless finish. The back coating truly elevates the bond of the sandwich panel insulation core to new heights. Once the primer-coated surfaces are fully baked, the coating is applied to the front surface, ensuring a flawless finish. They are re-baked, allowed to cool down, and then carefully packed in pre-painted coils, ready to play their vital role in the production of sandwich panels.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/section><section class=\"l-section wpb_row height_small\"><div class=\"l-section-h i-cf\"><div class=\"g-cols vc_row via_grid cols_2 laptops-cols_inherit tablets-cols_inherit mobiles-cols_1 valign_middle type_default stacking_default\"><div class=\"wpb_column vc_column_container\"><div class=\"vc_column-inner\"><div class=\"w-image align_none\"><div class=\"w-image-h\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/borjpooshesh.com\/wp-content\/uploads\/2024\/12\/5-5-4.webp\" class=\"attachment-large size-large\" alt=\"\" srcset=\"https:\/\/borjpooshesh.com\/wp-content\/uploads\/2024\/12\/5-5-4.webp 1024w, https:\/\/borjpooshesh.com\/wp-content\/uploads\/2024\/12\/5-5-4-300x300.webp 300w, https:\/\/borjpooshesh.com\/wp-content\/uploads\/2024\/12\/5-5-4-150x150.webp 150w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/div><\/div><div class=\"w-separator size_small\"><\/div><div class=\"w-separator size_small\"><\/div><\/div><\/div><div class=\"wpb_column vc_column_container us_custom_cf430219\"><div class=\"vc_column-inner\"><div class=\"w-separator size_small\"><\/div><div class=\"wpb_text_column\"><div class=\"wpb_wrapper\"><ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Insulating core<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Backing layer<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Passive layer<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Galvanization<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Steel<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Galvanization<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Passive layer<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Coating<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Final coating<\/span><\/li>\n<\/ol>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/section><section class=\"l-section wpb_row height_small\"><div class=\"l-section-h i-cf\"><div class=\"g-cols vc_row via_grid cols_1 laptops-cols_inherit tablets-cols_inherit mobiles-cols_1 valign_top type_default stacking_default\"><div class=\"wpb_column vc_column_container\"><div class=\"vc_column-inner\"><div class=\"wpb_text_column us_custom_432d3f53\"><div class=\"wpb_wrapper\"><p><b>Primer:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The double-sided galvanized roof sandwich panel consists of a central layer of polyurethane insulation foam, flanked by two layers of galvanized sheet on either side.\u00a0 The bonding of these three layers is achieved through the application of primer under pressure and heat.

The initial sign of installing sandwich panels is the combined and integrated application of polycarbonate along with sandwich panels. Accordingly, 18% of the roof covering must consist of polycarbonate, whereas the remaining 82% should be finished with sandwich panels. When sandwich panels are positioned side by side, they tend to overlap, creating a seamless connection that enhances the overall structure. When building a sturdy metal frame, the first step is to lay down those iron beams like a solid foundation. Next, the purlins are positioned horizontally atop them, creating a reliable support system. Finally, the roof sandwich panels are securely fastened to the purlins, ensuring everything is locked in place for a strong and durable structure.\u00a0 For example, in a project utilizing a 5-rib sandwich panel, the area beneath the fifth rib remains vacant, whereas the subsequent sandwich panel is positioned on the first rib, resulting in an overlap. Screws play a crucial role in keeping the ribs tightly secured together, ensuring everything stays in place just as expected. When it comes to drilling the ribs, a unique drill is employed to ensure everything goes smoothly and efficiently. The drill bit measures a solid 7 mm, whereas a slightly smaller 6 mm screw takes the spotlight. The reason behind this is that the volume of the perforated panel space experiences fluctuations due to the natural expansion and contraction processes. This handy little trick is also the secret sauce to really lock those panels together for a perfect fit! The fastening structure and the number of screws are designed to ensure that one screw is utilized at every rib along the gutter edges, particularly at the roof corners. However, in various areas, it is only the sections where the sandwich panels come together that are fastened with screws. Before installing the polycarbonates, which are sandwiched between the roof sandwich panels, it is necessary to finish assembling the panels. The work can proceed with the installation of the polycarbonates. Before the installation of polycarbonate on the purlins, it is essential to utilize central bracing brackets in the areas where the sandwich panel rib is devoid of support, ensuring that everything is perfectly aligned and secure throughout the process. In the parts where the ribs are fully intact, central bracing brackets are strategically positioned at an intermediate point on the purlins.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><b>Double-sided aluminum roof sandwich panel:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">This product is utilized in the roofing of different kinds of sheds, warehouses, cold storage facilities, and environments where hygiene is very important, such as clean rooms.\u00a0 Double-sided aluminum roof sandwich panels boast an impressively low weight of around 1 kg\/m<\/span><span style=\"font-weight: 400;\">2<\/span><span style=\"font-weight: 400;\">.

This will accelerate project execution and guarantee precise implementation, along with thorough, principled, and impeccable insulation and sealing. Aluminum sandwich panels exhibit lower strength than Aluzinc and galvanized ones. Therefore, it is advisable to utilize Aluzinc or galvanized coated panels in areas that are more susceptible to impact, pressure, and collisions with heavy objects. Due to its high thermal conductivity, aluminum is not commonly utilized in applications requiring thermal insulation, such as cold storage. Upon contact with water, cracks develop, leading to the formation of aluminum oxide. Consider washing these panels less frequently or shielding them with a protective layer of PVC.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Price of double-blind aluminum roof sandwich panel:<\/b><span style=\"font-weight: 400;\"> Apadana Borj Pooshesh Engineering Technical Group is dedicated to delivering high-quality products.
