Application of Galvanized Rectangular Tube

Advantages of Galvanized Rectangular Tube

• Good anti-corrosion and anti-rust performance
• Lightweight and high strength
• Beautiful appearance
• Good processing performance
• Safe and fireproof
• Strong versatility
• Easy and fast construction
• Environmental protection and energy saving

Galvanized Rectangular Tube Weight Calculation Formula

Calculation formula: W = [2 x (A+B) – 4 x S] x S x 7.85 x L ÷ 1000

• W is the weight of the rectangular tube (kg).
• A is the length of the long side of the rectangular tube (mm).
• B is the length of the short side of the rectangular tube (mm).
• S is the wall thickness of the rectangular tube (mm).
• L is the length of the rectangular tube.

The following is the theoretical weight per meter of galvanized rectangular tubes with sizes between 20×30mm – 60×150mm and thickness between 1.5mm – 5mm:

Short side length(mm)	Long side length(mm)	Wall thickness (mm)	Theoretical weight(kg/m)	Short side length(mm)	Long side length(mm)	Wall thickness (mm)	Theoretical weight(kg/m)

Galvanized vs Stainless Steel Rectangular Tube

Item	Galvanized rectangular tube	Stainless steel rectangular tube
Nature	A layer of zinc is plated on the surface of ordinary rectangular tubes	Alloy steel that is corrosion resistant without additional treatment
Strength characteristics	The tensile strength is usually between 400-550MPa, which can meet the requirements of conventional building and structural applications	The tensile strength can reach hundreds to thousands of MPa, with high strength
Corrosion resistance	In general atmospheric environment, the zinc coating can provide better protection	Excellent corrosion resistance, performs well in a variety of environments
Processability	Can be cut, welded, bent and other processing	Some stainless steels are difficult to process
Price	Relatively low	Usually higher
