The trend of using steel in the warehouse industry is becoming increasingly popular, ranging from constructing warehouse structures, canopies, to storage racks. In the warehouse industry, factors such as efficiency, durability, and cost-effectiveness play a crucial role, and steel is the material that can comprehensively meet these criteria, as outlined in the reasons in the following article.The durability of structures are enhanced through steel in the warehouse One of the reasons why steel is increasingly preferred and widely used in the warehouse industry is its durability and its ability to provide structural integrity. Especially in storage racks, a robust frame system is essential to support the load when storing a large quantity of goods for an extended period. Racks need a certain level of rigidity to avoid bending or deformation under the weight of the goods, and high-strength steel types contribute to ensuring the required stiffness and stability of the racks.The warehouse industry always demands long-term storage, where durability is crucial in facing the challenges of time. In regions with high humidity, fog, or near the sea, steel may encounter challenges from salt and oxidation. However, manufacturers can address this issue by applying additional layers of zinc coating to protect the steel surface and enhance the lifespan of storage structures.Flexibility in design helps expand storage space for goodsSteel with a certain level of flexibility brings about versatility in shaping and designing. Specifically, steel can be easily processed and designed in various sizes and shapes. This enables manufacturers to construct multi-tiered racks that are tall and vaulted without compromising stability. Additionally, the ability to extend the length across spans helps optimize the storage space for goods.Modern warehouses are typically categorized based on various storage needs, such as cold storage or distribution centers. Thanks to the ability to be processed in various forms, steel racks can meet diverse design requirements, for instance, catering to the low-temperature storage needs of cold storage facilities or optimizing storage space for distribution centers. Importantly, steel rack systems offer an open space within the warehouse, enhancing integration with automation systems, robots, and other smart devices to optimize the transportation, handling, and storage processes for goods.Using steel in warehouses helps save installation and regular maintenance costsIn the warehouse industry, cost-effectiveness is considered a paramount factor, and steel is an extremely suitable material for cost-saving solutions during both installation and regular maintenance. Typically, steel components are manufactured and shaped according to customer requirements in the factory. They are then transported directly to the delivery location, and the warehouse section only needs to arrange suitable installation locations. Utilizing pre-prepared components helps minimize installation time, allowing warehouse management to reduce labor costs and expedite project completion, enabling the warehouse to start operations sooner.In addition to its rigidity, one of the primary characteristics of steel is its excellent corrosion resistance, especially in the case of galvanized or stainless steel. Although the initial cost of installing steel components is considerably higher than that of other materials, the durability that steel provides helps management significantly save on fixed costs. The good corrosion resistance implies a reduced likelihood of deterioration, leading to a decrease in annual maintenance costs and limiting the frequency of repairs or replacements for components.Ensuring safety through fire resistanceWarehouses are crucial for storing goods, making safety within these spaces of utmost importance. Specifically, the ability to resist fire and moisture becomes a crucial factor in ensuring the safety of stored goods. Unlike some other building materials, steel is fire-resistant and non-combustible. The metallic nature of steel helps prevent water from infiltrating the structure, providing an effective defense against moisture. The steel's impermeability reduces the risks of damage caused by water, protecting goods from mold or decay due to dampness.Even in the event of a fire or explosion, steel maintains the integrity of the structure better than other materials, even when exposed to high temperatures. This is critical in emergency situations, as steel can withstand temperatures up to 1000 degrees Celsius. The low flammability and high heat resistance allow warehouse managers additional time to respond to emergencies, prolong evacuation times, and limit potential damages.Using steel in warehouse components provides high load-bearing capacity, ensuring that storage racks can withstand significant weights without encountering undesirable deformations. The durability and safety of steel not only help maintain the structural integrity but also reduce maintenance costs and enhance corrosion resistance, making the warehouse system stable and sustainable over time. Through this article, we hope that viewers can gain a more objective perspective on the role and long-term potential of steel in the warehouse industry.If you are looking to import steel for your project and are unsure about choosing a reputable manufacturing plant to ensure quality, please contact AG真人游戏 Steel for free assistance via email: [email protected] or Whatsapp: +84 76 911 2358.

The most important factor of a sustainable building is the source of quality construction steel. Depending on the property of each project, the contractor will choose some criterias to evaluate construction steel. Below is a list of common criteria for evaluating the quality of construction steel.Construction steel quality standardsThere are countless different types of steel on the market today, in order to create a common uniformity in the steel production process, quality standards have been issued. Manufacturing mills will often rely on these quality standards to adjust the specifications to ensure the quality of the steel grade is in the best condition.Three common quality standards including Vietnamese, American and Japanese standards are applied to steel constructions such as plain bar and rebar. In which, when the product meets Vietnamese standards, construction steel is considered as standard steel and is completely suitable for construction projects.TCVN - Vietnam steel standardVietnam confirms quality standards for steel grades is abbreviated in the form of TCVN, of which there are 4 general standards: TCVN 1651-1:2008, TCVN 1811_2009 (ISO 14284-1996), TCVN 6287_1997, TCVN 7937-1-2013.The plain bar steel used to make reinforced concrete and on each of them are marked CB240-T, CB300-T and CB400-T. Similar to plain bar steel, rebar steel also owns 3 standard steel grades including CB300-V, CB400-V, CB500-V, CB600-V. The numbers in the symbol will represent the strength of the steel. Specifically, the CB300-T series will indicate the value of strength is up to 300N/mm2, meaning that a steel bar with a cross section of 1mm2 will withstand a tensile force of up to 300N (equivalent to 30kg).ASTM - American steel standardThe American Standard is identified by its common abbreviation ASTM, will focus on key topics such as specifications, testing, and grading guidelines. The American standard applied in the current range of construction concrete steels is ASTM A615/A615M with 3 steel grades including GR40, GR60 and GR75.Most steel grades according to American standards are highly appreciated for their outstanding hardness when all 3 steel grades GR40, GR60 and GR75 possess tensile strengths of 420 MPa, 620MPa and 695MPa. Having the high tensile strength will be a plus point of this standard for building framing applications because they provide extremely good loading.JIS - Japanese steel standardThe Japanese standard is also one of the familiar standards in the steel industry with the abbreviation JIS. Currently, two popular Japanese standards are applied in construction steel including JIS G3505 - 1996, JIS G3112 - 1987.Construction steel specificationAnother important criterion in the selection of construction steel is the appropriate size including diameter, length and volume. Knowing the construction steel diameter will help the contractor easily calculate the required volume of construction steel for the project, especially for large projects that always require meticulousness and calculation in detail.If the contractor is not careful in choosing the right size, it is easy to make the structure weak because of unbalanced transmission forces in some loading parts. Famous construction steel suppliers in the Vietnam market such as Hoa Phat, Pomina, Viet Italy, ... are at risk of being faked as poor quality versions. Normally, the fake version of construction steel will have a smaller size from 0.5 - 0.8mm than the authentic one.Specification of steel standard TCVN 1651-2008Outside diameter桅6桅8D8D10D12D14D16D20D25D32D36D40D50Cross section(mm2)28.350.2750.277.8511315420131449180410181 2571 694Specific weight (kg/m)0.2220.3950.3950.6170.8881.211.582.473.856.317.999.8615.42Tolerance specific weight (%)卤8卤8卤8卤6卤6卤5卤5卤5卤4卤4卤4卤4卤4 Specification of steel standard JIS G3112 - 1987Outside diameterD10D13D16D19D22D25D29D32D35D38Cross section(mm2)71.33126.7198.6286.5387.1506.7642.4794.2956.61140Specific weight (kg/m)0.560.9951.5592.2493.0393.9785.0436.2347.5098.949Tolerance specific weight (%)卤6卤6卤5卤5卤5卤5卤4卤4卤4卤4 Specification of steel standard ASTM A615/ A615M-08Outside diameterD10D13D16D19D22D25D29D32D36Cross section(mm2)711291992843875106458191006Specific weight (kg/m)0.560.9941.5522.2353.0423.9735.066.4047.907Tolerance specific weight (%)卤6卤6卤6卤6卤6卤6卤6卤6卤6 Steel origin and the market priceThe standard steels must be the steel lines having clear origin, usually the manufacturer will attach labels showing characteristic symbols and brand names on each steel bundle.In addition, quality construction steels from reputable brands will always have a fixed price and the retail price will be listed from the manufacturer. If the price of steel is too low compared to the factory's selling price, it means that the quality of the steel will not be guaranteed.Quality construction steel must come from a reputable supplierBesides considering the quality criteria, choosing a reputable steel supplier is also an important factor to help get good construction steel.
