What is rectangular hollow section in Vietnam
Rectangular hollow section (RHS) is widely used in civil and industrial construction due to its numerous outstanding advantages, including high durability, ease of construction, low cost, and high load capacity. In this article, MSR Steel will go into greater detail about selecting the appropriate size RHS, the best price and the reputation of the most well-known brands in Vietnam.1. What is rectangular hollow sectionRectangular hollow section is a type of steel manufactured in hollow blocks with a common thickness of 0.7-4mm, the smallest size of RHS is 10 x 30mm and the largest is 60 x 120mm. RHS has a high carbon content, enhancing its strength and resistance to external impacts. Some RHS products are hot-dip galvanized to add anti-oxidation and anti-corrosion properties.2. Some applications of RHSRectangular hollow section is widely used in the construction and civil industries, specifically:Fences, walls, doorsApplication in steel structure, prefabricated houseAutomotive manufacturing sectorHousehold appliancesShipbuildingContainer productionHousing structure, agricultural greenhouseFurniture…3. Advantages of rectangular hollow sectionHigh QualityDue to its high carbon content, RHS is extremely durable and resistant to metal corrosion. This feature contributes to the extended lifespan of RHS-based construction projects. Low costIt is made up of materials that are easy to find and available, so the price is quite cheap. Because of this, using RHS helps to save construction costs for investors.Long life expectancyRHS is resistant to corrosion and rust, so the average life expectancy of the product is usually 60-70 years.DurableCarbon is one of RHS's main materials, so the product's surface is harder than regular steel.Durable coatingRectangular hollow section can be coated with zinc to resist mechanical impacts to serve applications such as means of transport, construction and some other industries.4.
