Pre-engineered steel buildings are becoming increasingly popular in construction projects due to their superior advantages over traditional concrete steel buildings. Let's MRS Steel explore this type of building and its pros and cons in today's article.1. Overview of prefabricated steel buildingsPre-engineered steel buildings refer to a type of house or facility constructed based on pre-manufactured steel components. Once these parts are produced, the construction team transports them to the site for assembly and completion. The entire construction process of a pre-engineered steel house goes through three main stages: design, component fabrication, and on-site assembly. Because of using available steel structures, the construction is faster and requires less manual labor.Compared to traditional houses, pre-engineered steel buildings have a distinct structural system. The main structure includes steel columns and beams designed to bear the load for the walls and roof. Regarding the foundation, which is the primary load-bearing base for the house, the pre-engineered steel homes still use reinforced concrete for their foundation. However, depending on requirements, one can choose for shallow or deep foundations. The supplementary structural system, which enhances the house's completeness, includes partitions, stair-support frames, and roof trusses made from C, Z, or I-beams.The roofing structure is typically made of metal sheets to shield the house from environmental and weather impacts. Commonly, the favored material for these roofs is PPGI/PPGL because of its excellent corrosion resistance and high heat tolerance.2. The outstanding advantages of prefabricated steel buildingsPreviously, prefabricated steel buildings were mainly used for constructions like warehouses, workshops and exhibition halls. However, in recent years, this type of building has become popular for residential purposes due to its flexibility, time efficiency, and affordability.2.1. Cost savingsThe steel houses generally have a lower construction cost than traditional concrete houses. This is because the number of materials used to construct the house is significantly reduced, mainly relying on columns, beams, and trusses for main structural support. Additionally, steel is a durable material, and the anti-rust and oxidation properties coming from galvanized steel can help reduce maintenance costs.2.2. Quick on-site constructionThe design, assembly and construction process of these houses is faster, more precise, and safer than traditional building methods. Main components like columns, beams, and steel bars are pre-manufactured in factories, so when these components are transported to the construction site, the assembly team simply follows the provided instructions.All processes such as cutting, drilling, welding, hole punching, and anti-corrosion painting are performed in the factory by using automated machinery. This means that measurements and quantities are pre-determined based on technical drawings, eliminating direct handling at the construction site and reducing technical errors and safety risks. A small prefabricated steel building can be completed in just a few weeks or even some days, while traditional houses can take several months to finish.2.3. High flexibilityUnlike traditional houses, which are permanent, the steel houses can be easily moved to another location. The structural components are connected with bolts and screws, allowing for easy disassembly and relocation.2.4. The prefabricated steel buildings are a type of multi-purpose houseOne of the outstanding advantages of these buildings is that they do not occupy too much space due to their compact structure. With just the addition of some furniture and fixtures, a comfortable living space can be created. Moreover, this type of house can serve multiple purposes across various sectors, including industrial, commercial, and residential.3. Looking for unit bring steel solution for your prefabricated steel building projectThanks to its flexibility and convenience in construction, as well as its cost-effectiveness, it's considered a solution that overcomes the drawbacks of traditional concrete houses. However, it's worth noting that the prefabricated steel buildings may be less sturdy than concrete houses due to their features such as reasonable costs, versatility, and convenience for various models. Therefore, to build such a house, contractors must find stable ground along with a mild climate to achieve better efficiency.While there are some concerns about sturdiness, selecting quality steel sources from the beginning process for the structural framework can significantly enhance the durability of this type of house.

Purlins are one of the materials that help support the structural framework, most often below the roof. Purlins carry the roof desk load and are supported by building walls, steel beams, rafters,... Purlins are an indispensable part of every project, so choosing the perfect purlin ensures the safety of the entire building. In this article, MRS Steel will share some tips for choosing the most suitable purlins to make the roof frame for the project.1. Choose the appropriate purlin materialPurlins combine with rafters to create a roof frame, combining the support of beam frames, walls or steel beams. When choosing the material of the purlin, importer can consider between black pipe steel, galvanized steel or high-strength steel. Each material has pros and cons in terms of strength and cost, so importers need to assess the building design to choose the most optimal material. However, to ensure the safety of the project, steel purlins must be able to withstand high loads, resist corrosion, rust and be unaffected by environmental factors.2. Choose the ideal type of purlinThis is one of the important factors when deciding which type of purlin for your project. C and Z shaped purlins are the two most popular types, have high applicability and unique characteristics as follows:C purlins are made from black or galvanized steel with a C shape and used in structural framework for factories, houses,... Importers can contact MRS Steel for advice on the most suitable dimensions, thickness and length for their specific application.Z purlins are manufactured from hot-rolled, cold-rolled, galvanized steel, shaped like the letter Z, so it is easy to stack and connect through bolted joints. Because of this characteristic, the Z shaped purlin has a higher thickness and durability than the C shaped purlin.3. Install purlins properlyCalculating the distance to install purlins compared to the corrugated iron roof in a reasonable, economical and safe way is important in choosing purlins for the project.Firstly, safety and sustainability are the top criteria, requiring the distance between purlins and corrugated iron roofs to be standard and reasonable. Next, if the purlins are not aligned or installed too far or too close, roofing will cost a lot of time and money. Finally, if the purlin distance is not suitable, it also reduces the building's load-bearing capacity, especially making it difficult to repair and maintain periodically.4. No weld/heat cutWelding or heat cutting methods are not used when installing purlins because high temperatures can affect the durability and strength of the purlins.5. Choose a reputable supplier and manufacturerPurlins are a key part in construction projects, so factories always produce many specifications to meet all customer needs. Importers can also find cheap sources from China, India,... but for some countries with strict regulations on C/O or trade defense measures, this option is not feasible. Meanwhile, Vietnam belongs to the group of countries with a developing economy, so it enjoys many preferential duty rates and import policies to the EU, United States, Australia, Mexico, Malaysia,...Vietnam has crude steel output ranked 13th on the world steel map and the largest in Southeast Asia, ensuring abundant and high-quality supply for customers. Many of Vietnam's largest factories do not receive orders directly from importers but through intermediary support units such as MRS Steel.MRS Steel provides solutions for importing Vietnamese steel to more than 30 countries around the world, with a network of links with many reputable steel factories and shipping lines to promote the fastest and most optimal delivery process.

Purlins are a specialized material used in frameworks and prefabricated houses to structural support and prevent rust and termites. Vietnam's increasingly developed manufacturing techniques have created many different types and standards of purlins. 1. What Is PurlinIn construction, a purlin is a horizontal bar or beam used in a roof support system. They are most commonly in buildings and are supported by the building’s rafters and its wall. Purlins are classified based on material and shape, serving different purposes. Purlins are very important in architecture and structure because without them, we cannot tile any other material on the roof.2. Types of Purlin in Steel BuildingC Shaped PurlinC shaped purlins are horizontal C-shaped bars that are light in weight, good strength and easy processing. The flat surface of the purlin is perforated to increase flexibility during assembly and construction. They are widely used in the construction of factories, houses, warehouses, shopping centers, airports,...Products commonly used for projects with column pitch <6m with common specifications are C200x50x1.8, C150x50x20x1.5,...Z Shaped PurlinZ shaped purlins are made with oval holes to easily connect the purlins together with bolts. This type is lightweight, easy to process and has better bearing capacity than C-shaped purlins. They are mainly used in projects with large areas such as factories, cold storages, commercial centers,... The most popular specifications are Z200x72x78x2.0, Z200x62x68x1.8,...Black Steel PurlinBlack steel purlins are made from hot-rolled black steel, known for its lightness, durable, heat-resistant, environmentally friendly and less deformed under strong impacts. However, black steel purlins are less widely used, especially in high-end projects because of their low aesthetic factor, low roughness and easy rust.Galvanized purlinsGalvanized purlins are black steel purlins covered with a layer of zinc plating to protect the surface. This enhances their durability, resistant to force and temperature and are especially resistant to rust and corrosion under weather conditions. High strength purlinHigh-strength purlins are manufactured by modern technology with higher quality than conventional purlins. The product has the ability to withstand high temperatures, the yield limit reaches a minimum of 350 MPa ~ 4500kg/cm2, light weight, large spans while still ensuring deflection within the standard range.3. What Purpose Do Purlins Serve In Construction?Purlins are divided into two types: roof purlins and regular purlins. In the prefabricated steel structures, builders often connect the purlins with round or V-shaped bars to firmly stabilize the purlin system.For columns of large factories with heights of 9-12m, purlins are supported by V-shaped struts to enhance the bearing capacity of the works. In addition to the role of bearing the roof load and human load, purlins are calculated and designed to bear the hanging load of wind ceilings, duct systems, electricity or decorative furniture.4. Where To Import Reputable And Quality Purlins From Vietnam?Steel purlins are one of the highly applicable products but not all purlins from every factory meet the required standards. In particular, some countries attach great importance to the issue of C/O when importing, so purlins must prove the origin of input materials.Vietnam is a country with crude steel output ranked 13th globally, advanced production technology, imported machinery systems from the most famous metallurgical brands such as Danieli, Tenova,... This has created the quality of Vietnamese steel, making Vietnam the largest steel industry in Southeast Asia.Under the escalating world economic and political situation, finding a reputable, quality steel supply source that is not in the group of embargoed countries is difficult for importers. Understanding these things, MRS Steel is a unit specializing in providing solutions to support the import of Vietnamese steel to more than 30 countries around the world.
