2 1/2 Galvanized Square Tubing Types

Yuantai Derun can produce two types of 2 1 2 x 2 1 2 square tubing, one called hot-dip galvanized 2 1 2 square tubing, with high zinc content, better corrosion resistance, higher price, and longer lifespan, generally around 20 years. One type is called pre galvanized 2 1/2 square tube, which has a thinner zinc layer than hot-dip galvanizing, lower corrosion resistance than hot-dip galvanizing, is cheaper, and generally has a lifespan of less than 7 years.

En10219 S355j2h 2 1/2 x 2 1/2 Square Tubing Making Process

At Yuantai Derun, there are two main production processes for EN10219 S355J2H 2 1/2 x 2 1/2 square tubing:
1. Hot dip galvanizing
Hot dip galvanizing EN10219 S355J2H 2 1/2 x 2 1/2 square tubing production process main steps: Black tube ->Surface treatment ->Hot dip galvanizing ->Cooling ->Passivation ->Inspection ->Spray label storage
2. Galvanized coil forming welding
Pre galvanized EN10219 S355J2H 2 1/2 x 2 1/2 square tube production process is smooth. Main steps: uncoiling galvanized coil ->trimming and welding ->straightening ->roll cold forming ->high-frequency welding ->removing excess flux ->sizing ->cooling ->cutting ->inspection ->spray label storage

En10219 S355j2h 2 1/2 Inch Square Tubing Chemical Composition

Carbon ≤ 0.22%, silicon ≤ 0.55%, manganese ≤ 1.60%, phosphorus ≤ 0.030%, sulfur ≤ 0.030%, nitrogen ≤ not required
Secondly, the mechanical properties of S355J2H are excellent, with a minimum yield point of 355MPa, a minimum tensile strength of 510-680MPa, a minimum elongation of 22%, and a maximum shrinkage of 30% after speckle. These mechanical performance parameters are relatively high, indicating that this low alloy structural steel can withstand large mechanical loads, and has good toughness in bending, impact, and other situations. It can also resist stress corrosion cracking in high or low temperature environments.
