Three solar installation systems for commercial building rooftops

Some large commercial buildings have open, flat roofs, which are places where sunlight lasts longer. How to build a photovoltaic mounting system on a flat roof? 1. Flat roof solar carport: The roofs of some commercial buildings are used as parking spaces, and carports with solar panels can be built. This system not only meets the needs of parking spaces, but also uses solar energy to generate electricity and save electricity for daily use throughout the commercial building. Carports typically consist of a solar-mounted steel structure with modules. The roof of the shed is made of BIPV, and photovoltaic modules...

Fixed and Tracking PV Mounting Systems

Photovoltaic brackets are key components of solar power generation systems and play a role in supporting and fixing photovoltaic power generation systems. With the rapid development of renewable energy, the types of solar mounting brackets are becoming more and more diverse. First, let’s introduce the common type of solar panel bracket – fixed solar rail installation. The fixed bracket is the most basic form of photovoltaic module bracket. Its structure is simple, stable and low cost. It is suitable for ground solar power stations and rooftop installation, and can be adjusted according to different angle requirements. The fixed solar bracket...

What do we mean by the term mild steel?

For example, “green steel” is often seen. For some people, it is just a marketing term with neither definition nor scope. You can use it whenever you want. But others believe that “green steel” is a term that requires certification. To use this term, it must cover the entire scope of sustainable development. Although these two groups of people are a bit extreme, how “green” does it need to be called “green steel”? Is the “green steel” I call “clean steel” or “zero carbon steel” what you call? Where exactly is the dividing line between “net zero carbon steel”, “zero...

Detailed price introduction of Prepainted Galvanized Color-coated Coils

Prepainted Galvanized Color-coated Coils (PPGI)is an important metal material widely used in the fields of construction, home appliances, automobiles, etc. Its surface has the characteristics of beauty, durability, corrosion resistance, etc., so it is highly favored in the market. This article will provide a detailed introduction to PPGI, including their manufacturing process, performance characteristics, application areas, and market prospects. 1, Manufacturing processPPGI are formed from hot-dip galvanized steel plates as the substrate after surface coating treatment. The manufacturing process mainly includes the following steps:Hot dip galvanizing: After degreasing, cleaning, melting and other treatments, the steel plate is hot-dip galvanized in a zinc pot...

The difference between CRGO and CRNGO

1, The difference between CRGO and CRNGOCRGO and CRNGO are commonly used silicon steel sheet materials inside transformers. CRGO is cold-rolled oriented electrical steel, while CRNGO is cold-rolled non oriented electrical steel. Their difference lies in the difference in magnetic flux density and permeability. CRGO has a higher magnetic flux density than CRNGO, but a lower magnetic permeability. This means that the magnetic permeability of CRGO is lower than that of CRNGO, but it also has higher energy conversion efficiency due to its high magnetic flux density.2, Differences in application scenariosCRGO and CRNGO are commonly used to manufacture equipment such as transformers, motors, and generators. Due...

What is the advantage of Pre-painted Galvalume steel coil?

PPGL is the abbreviation of Pre-painted galvalume typically with a hot dip Al-zinc coated steel substrate. It is made from the base metal cold rolled steel coil then undergone the process of coating an alloy of aluminium and zinc with the usual rate of 55% Al, 43.5% Zn,1.5% Si and painted with various painting types according to customers’ tastes. Rely on its excellence performance, pre-painted galvalume steel coil has been widely applied in building, sandwich panels, metal roofing, light industry, and other areas. As the fact that its different applications in many environment conditions, the choice of appropriate PPGL should be paid...

What is the difference between galvanized and galvanized aluminum-magnesium?

1. Definition 1. Galvalume: The hot-dip galvanized steel sheet is a cold-rolled steel sheet as the base material, and the coated steel sheet is obtained by hot-dip aluminum-zinc alloy coating on both sides. The mass percentage of the alloy composition of the coating is 55% Al, 43.5% Zn and 1.5% Si. 2. Galvanized aluminum magnesium: In the hot-dip galvanizing production line, the pre-treated steel strip is immersed in the molten zinc solution containing aluminum and magnesium to obtain the coating. The alloy coating composition has the following proportions: ①The magnesium content is 1.0~2.0%, and the aluminum content is 0.8~3.0% ②The...

DIFFERENCE BETWEEN PPGI AND PPGL STEEL SHEET IN COIL

Before we start discussing the difference between the two, it’s important you know what the terms “PPGI” and “PPGL” expand to. PPGI, which refers to Pre-painted galvanized iron steel. While PPGL stands for Pre-painted galvalume steel. Both of these steel variants are also known by the name of color coated steel in the industry. So, what’s the difference between PPGI Steel Coil and PPGL Steel Coil? Below we will show you an answer. The primary difference between the two types of steel coil is in the coating applied to each variant. PPGI or pre-painted galvanized iron steel coil is evenly covered with a layer of zinc. The zinc coating provides...
