Basic knowledge of steel bars
Rebar is a steel strip and is a type of building material.
1. What is galvanized corrugated steel sheet?
Galvanized corrugated steel sheet is a metal material made of cold-rolled steel sheet after pretreatment, electrogalvanizing and cold rolling.
What is corrugated steel sheet?
Corrugated steel sheet is a metal sheet with a special structure formed on the surface through a forming process.
Comparison of the difference between electro-galvanized steel coil and hot-dip galvanized steel coil
Galvanized coil is a kind of anti-corrosion steel coil product. Through the galvanizing process, a layer of zinc is formed on the surface of the steel coil to improve the corrosion resistance of the steel coil.
How much do you know about color coated boards?
Color coated steel coil is a product made of hot-dip galvanized steel sheet, hot-dip aluminum-zinc steel sheet, electro-galvanized steel sheet, etc., which is coated with one or several layers of organic coating on the surface after surface pretreatment (chemical degreasing and chemical conversion treatment), and then cured by baking. It is named after the colored steel coil coated with various colors of organic coatings, and is referred to as color coated steel coil.
What is galvanized steel strip？
Galvanized strip coated steel is a raw material made by coating cold-rolled or hot-rolled, long and narrow steel plates with a layer of material called (zinc) to varying degrees.
What are the specifications of patterned steel plates?
Patterned steel plates are rolled using metal embossing equipment.Steel plates with patterns on the surface are called patterned plates.
What material is cold rolled plate made of?
Cold-rolled coils are made of hot-rolled coils and are rolled at room temperature below the recrystallization temperature, including plates and coils.
The Difference Between Hot Rolled Steel and Cold Rolled Steel
The main difference between hot rolled steel and cold rolled steel is the processing. In the case of hot rolled steel, it is rolled at a high temperature to increase the crystallinity whereas cold rolled steel is rolled at a low temperature (below the crystallization temperature)
How many categories are there of galvanized steel pipes?
Galvanized steel pipe is a welded steel pipe with a hot-dip or electroplated zinc layer on the surface.
