Product Description:

 

Q355 and Q345 Furniture Galvanized Steel Tube 12m Length Decoiling Punching is a type of steel tube used in the furniture industry.

 

Q355 and Q345 are grades of low alloy high-strength structural steel. These grades offer improved mechanical properties such as higher strength and better durability compared to ordinary carbon steel. The "Furniture" designation indicates its intended application in the manufacturing of furniture.

 

"Galvanized" means the steel tube has been coated with a layer of zinc to provide corrosion resistance and enhanced durability. Galvanization protects the steel from rust and extends its lifespan.

 

The "12m Length" specifies the length of the steel tube, which is 12 meters. This length is suitable for various furniture designs and applications.

 

"Decoiling" refers to the process of uncoiling or unwinding the steel coil to obtain the steel tube. This allows for the customization and processing of the steel tube according to specific furniture requirements.

 

"Punching" is a process where holes or perforations are made in the steel tube. This may be necessary for attaching components or allowing for the passage of cables or wires in furniture assembly.

 

Overall, Q355 and Q345 Furniture Galvanized Steel Tube with a 12m length, decoiling, and punching capabilities are designed to meet the needs of the furniture manufacturing industry. They offer strength, corrosion resistance, and the ability to be customized for different furniture designs and assembly processes. These steel tubes are commonly used in the construction of frames, shelves, and other furniture components.
