JIS G3302 is a Japanese industrial standard that specifies the requirements for hot-dip galvanized steel sheets, coils, and cut lengths for general use. The standard covers steel sheets with zinc-coated (galvanized) coating weights of SGCC (commercial quality), SGCD1 (drawing quality), and SGCD2 (deep drawing quality).

Galvanized roofing sheets are commonly used in construction for their durability, strength, and corrosion resistance. They are made by cold-rolling sheets of steel to form a series of alternating ridges and grooves, which increase the sheet's strength and stiffness. The sheets are then hot-dip galvanized to protect them from corrosion and rust.

JIS G3302 galvanized roofing sheets are popular in applications such as residential roofing, industrial roofing, agricultural buildings, and infrastructure projects. They are available in a variety of thicknesses, widths, and lengths to suit different needs. The sheets can be easily installed using screws or nails and are often overlapped to provide a watertight seal.

In summary, JIS G3302 galvanized roofing sheets are a durable and reliable option for construction projects that require a strong and corrosion-resistant material.

Product advantage

1.Durability: Galvanized steel sheets are highly durable and resistant to corrosion, rust, and other forms of weathering, making them ideal for use in outdoor applications.

2.Strength: The corrugated design of the roofing sheets provides additional strength and stiffness, enabling them to withstand heavy loads and impacts.

3.Easy to install: Galvanized roofing sheets are easy to install, requiring only basic tools and fasteners. Their lightweight design also makes them easy to handle and transport.

4.Cost-effective: Compared to other roofing materials, galvanized roofing sheets are relatively inexpensive, making them a cost-effective option for construction projects.

5.Low maintenance: Once installed, galvanized roofing sheets require very little maintenance, making them a hassle-free option for building owners.

6.Energy efficient: Galvanized steel has a high solar reflectance, which means it reflects a significant amount of sunlight and reduces the amount of heat absorbed by the building, helping to keep the interior cooler and reducing energy costs.

7.Environmentally friendly: Galvanized steel is a recyclable material, making it an environmentally friendly option for construction projects.

Application

1.Residential roofing: Galvanized roofing sheets are a popular choice for residential roofing due to their durability, low maintenance, and cost-effectiveness.

2.Agricultural buildings: The strong and durable nature of galvanized roofing sheets makes them ideal for use in agricultural buildings such as barns and sheds.

3.Industrial buildings: The strength, durability, and corrosion resistance of these sheets make them suitable for use in industrial buildings such as factories, warehouses, and distribution centers.

4.Commercial buildings: Galvanized roofing sheets are also used in commercial buildings such as retail stores, offices, and restaurants.

5.Infrastructure projects: These sheets are also used in infrastructure projects such as bridges and highways as they are able to withstand heavy loads and harsh weather conditions.

6.Temporary structures: Galvanized roofing sheets are often used in temporary structures such as tents and shelters due to their ease of installation and portability.
