Features & Uses of Galvanized Steel Decking

1. High strength-to-weight ratio;

2. Attractive appearance;

3. Excellent resistance to corrosion, fire, and weather;

4. Concealed fasteners;

5. Light weight, easy and quick to install;

6. Less concrete usage & high efficiency.

 

Due to these great features, galvanized metal deck is widely used in many construction projects, for example,

1. High-rise buildings, such as business centers, hotels, bank buildings, shopping centers, etc.

2. Multi-storey buildings, for example, large supermarkets, schools, villas, car 4S stores, etc.

3. Public buildings, like stadiums, theaters, libraries, passenger stations, exhibition halls, airport terminals, concert halls, etc.

4. Industrial buildings, like warehouses, logistics centers, power plants, nuclear power plants, steel structure workshops, etc.

GP sheets are zinc-coated steel sheets used in construction and manufacturing for their durability and corrosion resistance. Common uses include roofing, making partition walls, ducting for HVAC systems, automotive body parts, and agricultural structures like grain silos. They are versatile, providing a strong, weather-resistant, and easy-to-fabricate material for a wide variety of applications. 

Galvanised roofing sheets

Galvanised roofing sheets are an excellent choice for those requiring a high-performance roof designed to last. Produced from steel or iron dipped in molten zinc, these sheets can last up to four times longer than other materials, making them the smart option for any serious building project. In addition, the sheets come in many different designs and profiles, adapting well to any roof construction, while their lightweight and cost-efficiency also work to their advantage.

● Galvalume roofing sheets

Galvalume roofing sheets are a highly durable roofing option due to their unique characteristics. Made out of steel or aluminium, an alloy of zinc and aluminium further strengthens these sheets. This coating combines the corrosion resistance of zinc with the sacrificial protection assistance of aluminium, meaning that it faces the elements with greater durability than other roofing solutions. With the classic look, flexibility, and powder finish options, galvalume is a prime choice for high-performance roofing materials.

Both materials provide a strong, long-lasting roof, but their performance has some differences.

Advantages

Here are the advantages of galvanised and galvalume roofing sheets:

The most significant benefits of galvanised roofing sheets are their low cost and long-lasting durability. In addition, the zinc coating used in galvanised roofing sheets offers excellent protection against rust and corrosion, making them well-suited for coastal and industrial environments where the air is moist. Galvalume roofing sheets offer similar protection from rust and corrosion. Still, they can also reflect a significant amount of the sun’s UV rays, making them suitable for applications where heat retention is important.

Disadvantages

Here are the disadvantages of galvanised and galvalume roofing sheets:

The main disadvantage of galvanised roofing sheets is their susceptibility to damage from hail and other debris. In addition, the zinc coating can wear off over time due to exposure to the elements, which means that galvanised roofing sheets may need to be replaced more often than galvalume sheets. Galvalume roofing sheets are also slightly more expensive than galvanised sheets, though the price difference is relatively small.

Choosing between galvanised and galvalume roofing sheets will depend on your specific requirements. Galvanised sheets may be the best choice if you are looking for a low-cost option with excellent durability. However, if you need a material that provides heat reflection and superior protection from the elements, then galvalume sheets may be the better option. Ultimately, it is important to consider all variables to make sure you select a material that is right for your project. Metal wall cladding with either galvanised or galvalume sheets can be a great investment for any building and provide you with the perfect balance of protection and aesthetic appeal.
