Replacing rooftop units (RTU’s) is a necessary task that building owners and managers should not overlook. RTU’s play a crucial role in heating, ventilation, and air conditioning (HVAC) systems in commercial buildings. Over time, these units can wear out, malfunction, or become inefficient, leading to increased energy costs and reduced comfort levels for occupants. In addition to replacing RTU’s, it is also important to ensure that the structure supporting these units can handle the weight and loading requirements to prevent any safety hazards. Signs That It’s Time To Replace RTU’s There are several signs that indicate it’s time to replace... View Article
Hollow Structural Sections (HSS) tube steel is a versatile material used in various industries such as construction, engineering, and manufacturing. It is known for its high strength, durability, and lightweight properties. But have you ever wondered how HSS tube steel is made? In this blog, we will take a closer look at the manufacturing process of HSS tube steel and explore the steps involved in its production. 1. Raw Materials: The first step in making HSS tube steel is to gather the necessary raw materials. These typically include hot-rolled steel coils and sheets, which are made up of carbon and...

Corrosion, the gradual deterioration of materials caused by chemical reactions with the environment, is a significant concern in numerous industries and applications, ranging from construction and automotive to electronics and packaging. Two commonly used metals, aluminum and galvanized steel, are known for their corrosion-resistant properties, making them popular choices for various purposes. However, the question of which metal is superior in terms of corrosion resistance remains a subject of debate among experts. In this blog post, we will explore the properties of aluminum and galvanized steel and discuss the factors influencing their corrosion resistance. Understanding Aluminum’s Corrosion Resistance Aluminum, a... View Article
Concrete is a versatile and durable material used in construction for a wide range of applications. It is essential to choose the right type of concrete for each project, as different formulations have different properties and strengths. Two commonly used types of concrete are Type II and Type IV. In this blog post, we will explore the differences between these two types and their respective uses in construction. 1. Definition and Composition Type II concrete is a general-purpose cement that is resistant to moderate sulfate attack. It contains a moderate amount of tricalcium aluminate (C3A) and is suitable for use... View Article
When it comes to roadway design and construction, engineers and designers rely on various parameters to ensure the durability, safety, and performance of the road. Two commonly used measurements in roadway design are CBR (California Bearing Ratio) values and Hveem R-Values. In this blog, we will explore the differences between CBR values and Hveem R-Values and discuss their significance in roadway design. 1. Understanding CBR Values: CBR values are used to assess the strength of subgrade soils, which play a critical role in supporting the road pavement. CBR is a measure of the load-bearing capacity of the soil, comparing its... View Article
