Q235 ordinary carbon structural steel is also called A3 steel.
Ordinary carbon structural steel - ordinary plate is a kind of steel material.
Q represents the yield limit of this material. The following 235 refers to the yield value of this material, which is about 235mpa. The yield value will decrease with the increase of material thickness. Due to moderate carbon content, good comprehensive properties, good combination of strength, plasticity and welding, it is most widely used.
Application:
1. It is widely used in architecture and engineering structures. It is used to make steel bars or build plant room frames, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc. it is also widely used as mechanical parts with low performance requirements. C. Grade D steel can also be used as some professional steel.
2. It can be used for various mold handles and other unimportant mold parts.
3. Q235 steel is used as punch material. It is used directly without tempering after quenching. The hardness is 36 ~ 40HRC, which solves the phenomenon of punch fragmentation in use.

PPGI is pre-painted galvanized steel, also known as pre-coated steel, color coated steel etc.

Using Hot Dip Galvanized Steel Coil as the substrate, PPGI is made by first going through surface pretreatment, then the coating of one or more layers of liquid coating by roll coating, and finally baking and cooling. The coatings used including polyester, silicon modified polyester, high-durability, corrosion-resistance and formability.

We are a PPGI & PPGL manufacturer in Shandong, China. Our PPGI (Prepainted Galvanized Steel) & PPGL (Prepainted Galvalume Steel) are available in a variety of specifications.

We could also provide the product life length lasts for decades as customers required.
