Hot-rolled steel is made by heating billets to over 1,000 degrees Celsius and then rolling them right away. It is several hundred yuan per metric ton cheaper than cold-rolled steel, and bigger, thicker and less likely to be damaged. Are you searching for a pressure resistant and flexible material, or a large format material? The right way is hot rolling. Cold rolling is too imprecise.<\/p>\n<p>First of all, the thickness should be sufficient. Cold rolling is typically limited to 3 mm for thicknesses between 1.2 and 40 mm, whereas hot rolling can directly produce large plates with a thickness of 40 mm and allows for customized adjustments. The material is thicker and stronger and able to withstand high loads. These can be, for example, main girders in a steel structure, crane foundations or frames for mining machinery. For these applications <a href=\"https:\/\/www.bomissteel.com\/kk\/product\/cr-coil-cold-rolled-steel-coil\/\">cold rolled materials<\/a> are almost out of the question. The material has good ductility, enough toughness, and good weldability as a result of hot rolling, and it does not break or become brittle during assembly.<\/p>\n<p>The dimensions are also adaptable. Width 600-2500 mm Length 2000-12000 mm If the project does not require a custom size, we will cut the material straight to the desired dimensions. This minimizes waste and reduces the need for on-site finishing. The disadvantages are that the surface is not cold-rolled, there is occasionally mill scale, and the dimensional accuracy is not as good. If surface finish is critical, <a href=\"https:\/\/www.bomissteel.com\/kk\/product\/cr-coil-cold-rolled-steel-coil\/\">cold-rolled steel sheet<\/a> is better suited. These two materials are inherently intended for different uses.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-7693 aligncenter\" src=\"https:\/\/www.bomissteel.com\/wp-content\/uploads\/2026\/08\/Hot-Rolled-Steel-Sheet.webp\" alt=\"Hot Rolled Steel Sheet\" width=\"550\" height=\"544\" srcset=\"https:\/\/www.bomissteel.com\/wp-content\/uploads\/2026\/08\/Hot-Rolled-Steel-Sheet.webp 550w, https:\/\/www.bomissteel.com\/wp-content\/uploads\/2026\/08\/Hot-Rolled-Steel-Sheet-300x297.webp 300w, https:\/\/www.bomissteel.com\/wp-content\/uploads\/2026\/08\/Hot-Rolled-Steel-Sheet-12x12.webp 12w, https:\/\/www.bomissteel.com\/wp-content\/uploads\/2026\/08\/Hot-Rolled-Steel-Sheet-100x100.webp 100w\" sizes=\"(max-width: 550px) 100vw, 550px\" \/><\/p>\n<h2>Specifications.<\/h2>\n<figure class=\"wp-block-table\">\n<table>\n<tbody>\n<tr>\n<td><strong>\u04e8\u043d\u0456\u043c\u043d\u0456\u04a3 \u0430\u0442\u0430\u0443\u044b<\/strong><\/td>\n<td>Hot Rolled Steel Sheet<\/td>\n<\/tr>\n<tr>\n<td><strong>\u0415\u043d\u0456<\/strong><\/td>\n<td>600 mm \u2013 2500 mm<\/td>\n<\/tr>\n<tr>\n<td><strong>\u049a\u0430\u043b\u044b\u04a3\u0434\u044b\u049b<\/strong><\/td>\n<td>1.2 mm \u2013 40 mm (customizable)<\/td>\n<\/tr>\n<tr>\n<td><strong>\u04b0\u0437\u044b\u043d\u0434\u044b\u0493\u044b<\/strong><\/td>\n<td>2000 mm \u2013 12000 mm, can be cut to size as needed.<\/td>\n<\/tr>\n<tr>\n<td><strong>Material<\/strong><\/td>\n<td>Q235A, Q235B, Q345A, Q355B, 20#\/45#, A36, S275JR, SS400, SM400A, SM490A, etc.<\/td>\n<\/tr>\n<tr>\n<td><strong>\u0421\u0442\u0430\u043d\u0434\u0430\u0440\u0442\u0442\u044b<\/strong><\/td>\n<td>ISO, JIS, GB, ASTM, DIN<\/td>\n<\/tr>\n<tr>\n<td><strong>\u0411\u0430\u0493\u0430<\/strong><\/td>\n<td>A, B<\/td>\n<\/tr>\n<tr>\n<td><strong>\u0411\u0435\u0442\u0442\u0456 \u04e9\u04a3\u0434\u0435\u0443<\/strong><\/td>\n<td>Galvanizing, pre-painting, and other surface treatments<\/td>\n<\/tr>\n<tr>\n<td><strong>\u04e8\u04a3\u0434\u0435\u0443<\/strong><\/td>\n<td>Cut-to-length, stamping, punching, embossing, etc.<\/td>\n<\/tr>\n<tr>\n<td><strong>\u049a\u0430\u043f\u0442\u0430\u043c\u0430<\/strong><\/td>\n<td>Standard export packing or as per requirement<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n<h2>Examples of Application<\/h2>\n<h3>What is hot rolled steel sheet used for?<\/h3>\n<p>They are required for load-bearing beam and column structures in a steel structure in high-rise buildings and industrial facilities.<\/p>\n<p>Thick steel plates are the foundation of construction machinery, the frame of mining equipment, the main beam of harbor cranes and the structure of heavy-duty equipment.<\/p>\n<p>The main beams of trucks and trailers and the bodies of freight cars must have strength and dependable welded joints.<\/p>\n<p>Note that the outer casings of tanks, boilers and other pressure vessels must also be manufactured from this particular brand, and not from any other sheet metal that is suitable for this purpose.<\/p>\n<h2>Processing and packaging.<\/h2>\n<p>Our factory has the sheet metal cutting machines, and provides the standard length cutting, stamping, welding, punching, embossing. The sheets are thick, dimensionally accurate and tightly controlled, saving you the hassle of transport. The packaging meets export standards. The securing of the products in shipping containers and the rust protection correspond to export standards or can be adapted to your requirements. You can calculate the metric tons per container based on density and before placing your order: length x width x thickness x 7.85. Weight is calculated by hand.<\/p>\n<h2>Common Questions.<\/h2>\n<p>Is hot rolling cheaper than cold rolling?<\/p>\n<p>Yes, hot rolled material is usually cheaper than cold rolled material per ton. Cold rolling is a step in the manufacturing process that hot rolling doesn&#8217;t have. If you want large thick sheets that have to stand high loads, hot rolling can be more economical. If the requirement is a clean surface and tight dimensional tolerances, then cold rolling must be considered.<\/p>\n<p>What thicknesses do you have? Is there a way to customize those?<\/p>\n<p>Usually up to 40mm in size. &#8220;Can we do any thickness in house? Width and length can be cut to standard lengths according to your product specs. We also take small quantities. Please send us the dimensions first, so that we can determine the weight and give you a quote.<\/p>\n<p>Is there mill scale on the surface?<\/p>\n<p>Mill scale is generally to be expected on hot-rolled material. But this is due to the manufacturing process and does not affect the load-bearing capacity. Galvanizing or pre-coating is an option if you have concerns about the surface. Later on, shot blasting can be used to remove the mill scale. What machining is needed?<\/p>\n<p>Do you produce pressure vessels?<\/p>\n<p>Yes, but for pressure-bearing systems the material of the outer shell is subject to strict requirements. This choice of material is not by chance. The test report shall be used to select the appropriate material grade and verify the operating conditions and the material grade before actual production according to the standards for a pressure vessel.<\/p>\n<p>How long does delivery take after purchase?<\/p>\n<p>Standard thicknesses and widths are stocked and can ship in a few days. Production planning is required for larger and custom sizes. I will confirm delivery date with you before I start planning. Shipments are shipped as consolidated freight full cartons.<\/p>\n<p>I would really appreciate if you could send me a test report.<\/p>\n<p>Yes, the goods are shipped with a certificate of shipping quality and a test report.
