Innovations in coated steel for PEBs PPGL, GL, and GP

Pre-engineered buildings are constructed using detailed designs and planning before the work begins. This method includes planning everything from the design and detailing of each part to the processes of fabrication, transportation, and erection. The main advantage of this approach is the time saved due to the detailed planning. Every aspect, including the connections with specific numbers of bolts, is designed in advance. As a result, there's no need to spend time fabricating on-site, as with conventional steel buildings; only the connections need to be made.

Pre-engineered buildings (PEBs) have become increasingly popular in construction due to their efficiency and cost-effectiveness. A key element of PEBs is coated steel, which offers durability and protection against the elements. The construction materials consist of roll-formed profiled sheeting designed for use in roofing and wall applications. These panels are available in color-coated, galvalume, or galvanised steel options and feature ribbed designs for added strength and durability. Let's explore some innovations in coated steel, focusing on pre-painted galvalume (PPGL), galvalume (GL), and galvanised (GI) steels.

Pre-painted galvalume (PPGL)

Pre-painted galvalume (PPGL) steel combines its strength with the anti-corrosive properties of a coating. This type of coated steel is known for its excellent resistance to weathering and rust. Adding paint enhances its aesthetic appeal and provides an additional layer of protection. PPGL is often used in roofing and wall panels, offering functionality and style.

Galvalume (GL) steel

Galvalume (GL) steel is coated with zinc and aluminium, providing superior corrosion resistance to regular galvanised steel. This makes it ideal for use in environments prone to rust and corrosion. Galvalume is used to construct roofing systems, wall panels, and structural frames. Its longevity and durability make it a preferred choice for PEBs.

Galvanised (GI) steel

Galvanised (GI) steel is coated with a layer of zinc to protect it from corrosion. This type of coated steel has been used for decades and is known for its reliability and affordability. GI steel is widely used in PEBs for various applications, including roofing, wall cladding, and framing. Its ease of fabrication and availability make it a popular choice among builders.

JSW Steel makes galvanized and galvalume products that meet high-quality standards and provide reliable performance in construction. The steel coils and sheets are versatile and can be used for roofing, wall cladding, and structural purposes in PEBs.

Benefits of using coated steel in PEBs

Durability: coated steel offers excellent protection against corrosion, extending the life of the building components.

Aesthetic appeal: the availability of pre-painted options like PPGL allows for a variety of colour choices, enhancing the visual appeal of the structures.

Cost-effectiveness: using coated steel reduces maintenance costs and increases the lifespan of the building, providing long-term savings.

Versatility: coated steel can be used in various parts of a PEB, from roofing and walls to structural frames, making it a versatile construction material.

Choosing the right coated steel

When selecting coated steel for your PEB project, consider environmental conditions, aesthetic requirements, and budget. PPGL is ideal for projects where both aesthetics and durability are important. GI steel is suitable for harsher environments due to its superior corrosion resistance. GI steel is a cost-effective option for general applications with sufficient traditional protection.

Conclusion

Innovations in coated steel, such as PPGL, GL, and GI, have significantly contributed to advancing pre-engineered buildings. These materials offer durability, aesthetic appeal, and cost-effectiveness, making them essential in modern construction.
