Product Details

HDG Hot Dip Galvanized Square Hollow Section Steel SHS ASTM A53

Product Description:

HDG (Hot Dip Galvanized) Square Hollow Section Steel SHS (Structural Hollow Section) ASTM A53 is a type of steel with specific characteristics.

HDG Hot Dip Galvanized means the steel has been coated with a layer of zinc through the hot dip galvanizing process, providing enhanced corrosion resistance.
Square Hollow Section Steel SHS refers to the shape of the steel, which has a square cross-section with a hollow center.
ASTM A53 is the standard specification followed for this type of steel, ensuring certain quality and performance criteria.
This steel is commonly used in construction, structural applications, and fabrication. It offers strength, durability, and protection against rust. The square hollow section allows for efficient use of steel while reducing weight.
The HDG coating adds an extra layer of protection, making it suitable for outdoor and corrosive environments. It can be used in frames, columns, handrails, and various structural components.
